AMD Smart Access Memory (Resizable BAR) Guide

Find out what AMD Smart Access Memory is all about, and how to turn it on for a FREE BOOST in performance!

 

Smart Access Memory : PCIe Resizable BAR for AMD!

Smart Access Memory is AMD’s marketing term for their implementation of the PCI Express Resizable BAR (Base Address Registers) capability.

What does that mean exactly?

CPUs are traditionally limited to a 256 MB I/O memory address region for the GPU frame buffer. This of it as an “data dump” for stuff like textures, shaders and geometry.

Since this “data dump” is limited to 256 MB, the CPU can only send texture, shader and geometry data as and when the GPU requires them.

This introduces some latency – delay from when the GPU requires the data, and the CPU send them.

Turning on Resizable BAR or Smart Access Memory greatly expands the size of that data dump, letting the CPU directly access the GPU’s entire frame buffer memory.

Instead of transferring data when requested by the GPU, the CPU processes and stores the data directly in the graphics memory.

Graphics assets can be transferred to graphics memory in full, instead of in pieces. In addition, multiple transfers can occur simultaneously, instead of being queued up.

While this AMD graphic above suggests that Smart Access Memory will widen the memory path (and thus memory bandwidth) between the CPU and GPU, that is not true.

Smart Access Memory / Resizable BAR will not increase memory bandwidth.

What it does is let the CPU directly access the entire GPU frame buffer memory, instead of using the usual 256 MB “dump”. That reduces latency because the graphics assets are now accessible by the GPU at all times.

 

AMD Smart Access Memory : Performance Gains

According to AMD, enabling Smart Access Memory will give you a small but free boost of 5% to 11% in gaming performance.

Here is a summary of the test results from our article, RX 6800 XT Smart Access Memory Performance Comparison!

You can expect up to 16% better performance in some games, but no effect in certain games. But overall, you get a free boost in performance. There is simply no reason not to enable Smart Access Memory.

1080p Resolution (1920 x 1080)

1440p Resolution (2560 x 1440)

2160p Resolution (3840 x 2160)

 

AMD Smart Access Memory : Requirements

Since Smart Access Memory is just an AMD implementation of PCI Express Resizable BAR. Therefore, it can be be implemented for all PCI Express 3.0 and PCI Express 4.0 graphics cards and motherboards.

However, AMD is currently limiting it to a small subset of components, having validated it only for their new Ryzen 5000 series CPUs, select Ryzen 3000 Series Processors and Radeon RX 6000 series graphics cards.

So this is what you currently require to enable AMD Smart Access Memory :

Hardware

Software

  • AMD Radeon Software Driver 20.11.2 or newer
  • Latest Motherboard BIOS (AMD AGESA 1.1.0.0 or newer)

AMD currently recommends these X570 motherboards, because they have updated BIOS available :

 

AMD Smart Access Memory : How To Enable It?

If you have all of those supported components above, and updated your motherboard BIOS, you need to manually enable Smart Access Memory.

Now, the method will vary from motherboard to motherboard, and it probably won’t even be called Smart Access Memory.

Instead, look for variations of Above 4G Decoding, or Resizing BAR, or Resizable BAR, or Re-Size BAR Support.

AMD Generic Method

AMD has provided these generic steps to enable Smart Access Memory :

  1. Enter the System BIOS by press <DEL> or <F12> during the system startup.
  2. Navigate to the Advanced Settings or Advanced menu.
  3. Enable “Above 4G Decoding” and “Re-Size BAR Support“.
  4. Save the changes and restart the computer.

Step-by-Step Method For ASUS Crosshair VIII Hero

In our guide, we are using the ASUS CROSSHAIR VIII Hero (AMD X570) motherboard, as an example :

  1. First you will need to turn off CSM (Compatibility Support Module), or make sure it’s disabled.Go to the Boot menu and look for a CSM / Compatibility Support Module option.

  1. Set CSM (Compatibility Support Module) to Disabled.

  1. Go to the Advanced menu and look for the PCI Subsystem. In other motherboards, look for PCIe / PCI Express configuration options.

  1. Enable Above 4G Decoding.

  1. This will give you access to the Re-Size BAR Support option. Set it to Auto.

  1. Now go to the Exit menu, and select Save Changes & Reset.

  1. It will ask you to confirm the changes. Just verify both, and click OK.

After the motherboard reboots, AMD Smart Access Memory (PCIe Resizable BAR) will be enabled for your Ryzen 5000 series CPU and Radeon RX 6000 series graphics card!

 

CSM Warning For GIGABYTE AORUS X570 Master

AMD currently recommends these X570 motherboards, because they have updated BIOS available :

CSM is disabled by default for the ASUS, ASRock and MSI motherboards. However, it is enabled by default in the GIGABYTE AORUS X570 Master.

If you installed Windows without first turning CSM off, it will be configured as non-UEFI. It will NOT boot if you enable Resizable BAR Support (Smart Access Memory).

You will need to reinstall Windows with CSM support disabled.

NVIDIA To Introduce Resizable BAR In February 2021!

NVIDIA just announced that they will introduce Resizable BAR support at the end of February 2021!

Find out what Resizable BAR is all about, and why it matters!

 

Resizable BAR : What Is It?

Resizable BAR is an optional PCI Express feature, that can deliver a small but free boost in performance for the graphics card.

CPUs are traditionally limited to a 256 MB I/O memory address region for the GPU frame buffer. The CPU can only transfer data like textures, shaders and geometry to the GPU through that small 256 MB “window”.

Turning on Resizable BAR expands that small access window, letting the CPU directly access the GPU’s entire frame buffer memory.

Those graphics assets can thus be sent in full, instead of in pieces. In addition, multiple transfers can occur simultaneously, instead of being queued up.

 

NVIDIA To Introduce Resizable BAR In February 2021!

AMD was first out the door with Resizable BAR in November 2020, launching it as Smart Access Memory.

It gave their Radeon RX 6800 XT graphics card a free performance boost of up to 16% in some games, but no effect in other games.

You can check out the performance difference in our article, RX 6800 XT Smart Access Memory Performance Comparison!

On 12 January 2021, NVIDIA announced that they will be able to introduce Resizable BAR support in GeForce drivers from Late February 2021 onwards.

It will be limited to their GeForce RTX 30 series graphics cards and laptops, but will work with both Intel and AMD CPUs.

The newly announced GeForce RTX 3060 will ship with support for Resizable BAR. However, older GeForce RTX 30 series cards will need to have their VBIOS updated from March 2021 onwards.

The motherboard must also be updated with Resizable BAR support. According to Intel, this will be limited to 11th Gen platforms, and select 10th Gen platforms.

So ironically, Resizable BAR will first work on GeForce RTX 30 series graphics cards paired with AMD Ryzen 5000 processors and AMD 500-series motherboards!

Precision Boost Overdrive 2 : Adaptive Undervolting Comes To Ryzen!

AMD just introduced Precision Boost Overdrive 2 (PBO2), which introduces adaptive undervolting for Ryzen processors, amongst other improvements.

Find out what Precision Boost Overdrive 2 offers, and what effect it has on performance of AMD Ryzen 5000 series processors!

 

Precision Boost Overdrive 2 : Improved Overclocking + Adaptive Undervolting!

Precision Boost Overdrive is the dynamic overclocking capability built into AMD Ryzen processors, with these features :

  • raises socket power limit
  • raises motherboard VRM limit
  • can override max boost frequency
  • primarily designed to improve multi-thread performance

Precision Boost Overdrive 2 (PBO2) comes with all of the original PBO features, as well as these new features :.

  • improved single-thread performance
  • adds adaptive undervolting capability
  • adds standalone undervolting capability for AMD Ryzen 5000 Series processors
  • improved performance per watt.
  • can lower operating temperatures.
  • ability to customise voltages and frequencies to a specific processor.

 

Precision Boost Overdrive 2 : Curve Optimizer

The new adaptive undervolting capability in Precision Boost Overdrive 2 (PBO2) is achieved through the Curve Optimizer.

The new Curve Optimizer tells the firmware what window of undervolting is desired, and adapts to both light and heavy workloads.

Undervolting, however, will not be done with raw millivolts. Instead, it will be applied with “counts“.

  • 1 Count is approximately 3 mV ~ 5 mV. This range means less undervolting during high loads, and more undervolting when the load is lower.
  • You can adjust the voltage by +/- 30 Counts. 30 Counts would be a range of 90~150 mV.
  • The adjustments can be applied per core, or on all cores.

The Curve Optimizer algorithm is adaptive – so it will automatically underplot when the circumstances are suitable, and restore voltage when it needs to.

 

Precision Boost Overdrive 2 : Performance Boost

According to AMD, PBO2 offers better single-threaded performance than the original PBO.

Enabling it will let the Ryzen 7 5800X deliver 2.6% better 1T performance in CINEBENCH R20, while the Ryzen 9 5900X delivers 2% better 1T performance.

Hardly earth-shattering performance, but hey, it’s free!

Multi-threaded performance also gets a small but nice boost from PBO2.

AMD says the Ryzen 7 5800X should get a 2.2% boost, while the Ryzen 9 5900X gets a very nice 10% boost in multi-threaded performance!

 

Precision Boost Overdrive 2 : System Requirements

Here are the system requirements for Precision Boost Overdrive 2 to work :

  • AMD Ryzen 5000 Series desktop processor
  • AMD 500 or 400 Series motherboard
  • Motherboard BIOS based on AMD AGESA 1.1.8.0 or later

The PBO2 update is available for all AMD Ryzen 5000 Series desktop processors through a motherboard BIOS upgrade available in December 2020.

AMD Zen 3 Tech Report : What’s New, What’s Unchanged?

Take a look at what’s new in the AMD Zen 3 microarchitecture, and what they borrowed from the last-gen Zen 2 microarchitecture!

 

AMD Zen 3 Architecture

Codename Vermeer, Zen 3 is the next evolution of the AMD Zen architecture.

While it obviously borrowed considerably from the existing Zen 2 architecture, AMD says it is a ground-up redesign that with major performance and functionality improvements in every area of the core.

These architectural changes allow Zen 3-based processors, like the Ryzen 5000 series, to deliver a 19% improvement in instructions per clock (IPC).

Front-End Enhancements

  • Faster fetching, especially for branchy and large-footprint code
  • L1 branch target buffer doubled in size to 1024 entries for better prediction latency
  • Improved branch predictor bandwidth
  • Faster recovery from misprediction
  • “No bubble” prediction capabilities to make back-to-back predictions more quickly and better handle branchy code
  • Faster sequencing of op-cache fetches
  • Finer granularity in switching of op-cache pipes

Execution Engines

  • Reduce latency and enlarge structures to extract higher instruction-level parallelism (ILP)
  • New dedicated branch and st-data pickers for integer, now at 10 issues per cycle (+3 vs. Zen 2)
  • Larger integer window at +32 vs. Zen 2
  • Reduced latency for select float and int operations
  • Floating point has increased bandwidth by +2 for a total of 6-wide dispatch and issue
  • Floating point FMAC is now 1 cycle faster

Load Store

  • Larger structures and better prefetching to support the enhanced execution engine bandwidth
  • Overall higher bandwidth to feed the appetite of the larger/faster execution resources
  • Higher load bandwidth vs. Zen 2 by +1
  • Higher store bandwidth vs. Zen 2 by +1
  • More flexibility in load/store operations
  • Improved memory dependence detection
  • +4 table walkers in the TLB

SOC Architecture

  • Reduce dependency on main memory accesses, reduce core-to-core latency, reduce core-to-cache latency.
  • Unify all cores in a CCD into a single unified complex consisting of 4, 6, or 8 contiguous cores
  • Unify all L3 cache in a CCD into a single contiguous element of up to 32 MB
  • Rearchitect core/cache communication into a ring system

 

AMD Zen 3 SoC Design

In addition to micro architectural improvements, Zen 3 (Vermeer) also features SoC design changes.

In Zen 2, each CCD (Compute Die) is made up of two CCX (core complexes), each with a 16 MB L3 cache.

Zen 3 uses a unified complex, in which each CCD now contains a single CCX with a unified 32 MB L3 cache.

This unified CCD design completely eliminates CCX-to-CCX communication, greatly improving core-to-core latency.

On the other hand, AMD reused the chiplet design, with one or two CCDs (fabricated on 7 nm) paired with a 12 nm IOD (I/O Die).

Reads from CCD to IO are still 2X write, to conserve die area and transistor budget. And it uses the same IOD from Matisse (Zen 2).

 

AMD Zen 3 Transistor Count + Die Size

The new Zen 3 CCD has 4.15 billion transistors, with a die size of 80.7 mm². That’s up from the 3.8 billion transistors and a die size of 74 mm² for the Zen 2 CCD.

The Matisse-era IOD remains the same – 2.09 billion transistors, with a die size of 125 mm².

They will both be manufactured using the same 7 nm TSMC process for CCD, and 12 nm Global Foundries process for IOD.

Core Die Zen 3 Zen 2
Process 7 nm TSMC
Transistors 4.15 billion 3.8 billion
Die Size 80.7 mm² 74 mm²
I/O Die Zen 3 Zen 2
Process 12 nm GoFlo
Transistors 2.09 billion
Die Size 125 mm²

 

AMD Zen 3 Precision Boost : No Change

Precision Boost 2 in Zen 3 remains the same as that of Zen 2, just with higher frequencies to “play with”.

It is an opportunistic boost algorithm that drives the loaded cores to the highest possible frequency, until it hits any one of these limits :

  • socket power
  • VRM thermal limit
  • VRM current limit
  • maximum clock speed

Precision Boost 2 will dynamically analyse and boost or dither the core clock speeds every 1 ms using the Infinity Fabric command and control functions.

In this example of the new Ryzen 9 5900X with a base clock of 3.7 GHz and a boost clock of 4.8 GHz, Precision Boost 2 will typically result in frequencies of 4.4 GHz to 4.6 GHz, even with 24 threads running at the same time.

 

AMD Zen 3 Voltage Range : No Change

Despite the changes in the microarchitecture and SoC design, Zen 3 processors will continue to be engineered with the same voltage range as Zen- and Zen 2-based processors.

The typical voltage range will vary according to usage, but basically, Zen 3 processors, like the Ryzen 5000 series, will support 0.2 V to 1.5 V.

 

AMD Zen 3 Temperature Range : No Change

AMD Zen 3-based processors will also have the same temperature ranges as Zen- and Zen 2-based processors.

Note : The temperature range below assumes an enclosed chassis, and an air-conditioned room.

 

AMD Zen 3 Memory Overclocking : No Change

Only the Zen 3 core chiplet die (CCD) is new in the Ryzen 5000 series processors. They continue to use the same IO die (IOD) as the 3rd Gen Ryzen processors.

Therefore, the relationship between Infinity Fabric Clock (fclk), Memory Controller Clock (uclk) and Memory Clock (mclk) remains the same.

For optimal performance, they are synchronous – in a 1:1:1 ratio. But users can choose a 1:1:2 ratio if they have trouble overclocking memory.

Unboxing The AMD Ryzen 9 5950X

The AMD Ryzen 9 5950X comes in a slimmer box, because it doesn’t come with any bundled cooler.

The last-generation Ryzen 9 3900X, you may recall, came with the Wraith Prism cooler.

 

The AMD Ryzen 9 5950X Up Close!

The AMD Ryzen 9 5950X has sixteen Ryzen processor cores, with a 3.4 GHz base clock, and a 4.9 GHz boost clock.

It has a 105 watt TDP, and supports SMT (simultaneous multi-threading), which means it can handle up to 32 threads simultaneously.

Like the 3rd Gen Ryzen, it has 512 KB L2 cache per core, for an 8 MB L2 cache size; and a massive 64 MB L3 cache.

The AMD Ryzen 9 5950X can be installed unto existing AMD 500 series motherboards, and later, the AMD 400 series as well, after a simple BIOS update.

AMD Ryzen 9 5950X : 3D Rendering Speed

CINEBENCH R20 is a real-world 3D rendering benchmark based on the MAXON Cinema 4D animation software.

It is a great way to accurately determine the actual performance of a processor in 3D content creation.

CINEBENCH R20 Single Core Performance

This Single Core test is not reflective of real world performance, but it is useful to find out the performance of the individual core.

Like the Ryzen 7 5800X, the Ryzen 9 5950X broke past the 600 mark, and was 22.5% faster than the Ryzen 7 3700X.

Because it has a 11.4% higher boost clock, that works out to a 10% better performance per clock, over the last-generation Ryzen.

CINEBENCH R20 Multi Core Performance

The Multi Core test shows the processor’s real-world 3D rendering performance.

A score of almost 9900! That makes it 66% faster than the Ryzen 7 5800X, and 2X faster than the Ryzen 7 3700X, both 8-core, 16-thread processors.

Multi-Threading Boost

This is not a CINEBENCH benchmark result. The Multi-Threading Boost is our calculation of the performance boost that the processor’s Multi-Threading capability provides.

For some reason, the Ryzen 9 5950X doesn’t benefit at all from its SMT capability.

That’s why it only has a 66% performance advantage over the Ryzen 7 5800X, despite having twice as many cores.

 

AMD Ryzen 9 5950X : Transcoding Speed

HandBrake is a free, open-source video transcoding utility, which converts a video file from one resolution / format to another.

As you can imagine, it’s very compute-intensive, which makes it a great benchmark for multi-core processors. In our test, we converted a 4K video of 1.3 GB in size into a 1080p video (HQ1080p30).

Very nice! The AMD Ryzen 9 5950X was 30% faster than the Ryzen 7 5800X, 44% faster than the Ryzen 7 3700X and 74% faster than Ryzen 7 2700X.

 

AMD Ryzen 9 5950X : Radial Blur Speed

The radial blur filter adds the perception of motion to a picture. This is a compute-intensive operation that benefits from multiple processing cores.

This radial blur test was performed on Photoshop 2020 using a single 13.5 megapixel photo, with a filesize of 4,910,867 bytes.

This is a huge boost in performance! The AMD Ryzen 9 5950X was 87% faster than the Ryzen 7 5800X, 2.33X faster than the Ryzen 7 3700X and 2.67X faster than the Ryzen 7 2700X.

Synthetic Game Test : 3DMark

We used 3DMark’s Time Spy and Time Spy Extreme synthetic benchmarks, which supports DirectX 12, and the latest features like asynchronous compute, and multi-threading support.

Time Spy – 2560 x 1440

The AMD Ryzen 9 5950X was 5% faster than the Ryzen 7 5800X20% faster than Ryzen 7 3700X, and 40% faster than Ryzen 7 2700X.

Of course, the CPU only has a slight influence on a game’s performance, so its effect on the overall gaming score is less significant.

Time Spy Extreme – 3840 x 2160

At the higher 4K resolution, the AMD Ryzen 9 5950X was 20% faster than Ryzen 7 5800X, 81% faster than Ryzen 7 3700X, and 2.3X faster than Ryzen 7 2700X and Core i7-8700K.

Now check out the processors’ effect on the overall gaming score… Obviously, CPU performance only has a small effect at this resolution.

 

F1 2019

F1 2019 is a racing game by Codemasters, released on 28 June 2019. We tested it on three resolutions at the Ultra High settings :

  • 1080p : 1920 x 1080 pixels
  • 1440p : 2560 x 1440 pixels
  • 2160p : 3840 x 2160 pixels

1080p Gaming Resolution

Look at that. The AMD Ryzen 9 5950X delivered 6% higher frame rates than the Ryzen 7 3700X, and 12% higher frame rates than the Ryzen 7 2700X!

1440p Gaming Resolution

At the higher 1440p resolution though, the effect of CPU performance was negligible, even with the GeForce RTX 2080 SUPER.

2160p Gaming Resolution

At 4K resolution, processor performance had no effect. The game was graphics-limited, not CPU-limited.

World War Z

Based on the 2013 movie, World War Z is a relatively recent third-person shooter game, released in April 2019.

We tested it on three resolutions using the Vulkan API at the High settings :

  • 1080p : 1920 x 1080 pixels
  • 1440p : 2560 x 1440 pixels
  • 2160p : 3840 x 2160 pixels

1080p Gaming Resolution

Look at that! The AMD Ryzen 9 5950X topped this comparison, tying with the Ryzen 7 5800X.

It delivered 16% higher frame rates than the Ryzen 7 3700X, and 20% higher frame rates than the Core i7-8700K.

1440p Gaming Resolution

When we bumped the resolution up to 1440p, it really didn’t matter that much which processor we used. They all performed about the same.

2160p Gaming Resolution

At 4K resolution, processor performance had absolutely no effect. The game was completely graphics-limited.

 

Strange Brigade

Strange Brigade is a third-person shooter game, released in August 2018. We tested it in three resolutions using the Vulkan API at the Ultra High settings :

  • 1080p : 1920 x 1080 pixels
  • 1440p : 2560 x 1440 pixels
  • 2160p : 3840 x 2160 pixels

1080p Gaming Resolution

CPU performance had only a small effect on frame rates in Strange Brigade, even at 1080p.

1440p Gaming Resolution

At 1440p, they were virtually all equal in performance. The game was already graphics-limited.

2160p Gaming Resolution

It was the same at 4K, of course – the game was completely graphics-limited.

Metro Exodus

Metro Exodus is a first-person shooter game, released in February 2019. We tested it in three resolutions using the Ultra settings :

  • 1080p : 1920 x 1080 pixels
  • 1440p : 2560 x 1440 pixels
  • 2160p : 3840 x 2160 pixels

1080p Gaming Resolution

Metro Exodus is graphics-intensive, so CPU performance has limited effect on its frame rate.

1440p Gaming Resolution

All of the processors performed the same at 1440p, with a slight edge to the Core i7-8700K.

2160p Gaming Resolution

At 4K, the game was completely graphics-limited, so it didn’t matter which processor we tested.

 

Ashes of the Singularity

Ashes of the Singularity is a 2016 game that supports multi-core processing and asynchronous compute.

In this game, the single core CPU performance has a significant effect on the actual frame rate.

We tested it on three resolutions using the DirectX 12 API at the High settings :

  • 1080p : 1920 x 1080
  • 1440p : 2560 x 1440
  • 2160p : 3840 x 2160

1080p Gaming Resolution

Look at that! The Ryzen 9 5950X delivered 9% higher frame rates than the Ryzen 7 5800X21% higher frame rates than the Core i7-8700K, and 23% higher frame rates than the Ryzen 7 3700X.

1440p Gaming Resolution

At 1440p, the Ryzen 9 5950X delivered 7% higher frame rates than the Ryzen 7 5800X, and 23% higher frame rates than both the Core i7-8700K and the Ryzen 7 3700X.

2160p Gaming Resolution

Even at 4K, CPU performance mattered in Ashes of the Singularity. The Ryzen 9 5950X delivered just 2% higher frame rates than the Ryzen 7 5800X, and 14% higher frame rates than both the Core i7-8700K and the Ryzen 7 3700X.

AMD Ryzen 9 5950X : Our Verdict + Award!

Thanks to the new Zen 3 core optimisations and SoC design, the AMD Ryzen 9 5950X offers a nice leap forward in performance.

It offers significantly better single-core and multi-core performance over the last generation, offering a nice boost to both content creation and gaming performance.

As our benchmark results show, the Ryzen 9 5950X offers a large performance boost over the Ryzen 7 3700X and Ryzen 7 2700X, and even the new Ryzen 7 5800X.

With 16 cores that support up to 32 threads, it barrels through everything thrown at it without a sweat.

But while AMD has highlighted the Ryzen 9 5950X as a great processor for gaming, it’s really best for serious content creation work.

It’s not that it won’t work well in games, it’s just overkill for games.

We cannot emphasise this great point about the Ryzen 9 5950X – even though it uses a new Zen 3 microarchitecture, it continues to use the AM4 socket.

If you have an existing AMD 500 Series motherboard, you can just pop in the Ryzen 9 5950X after a BIOS upgrade.

Those on AMD 400 Series motherboards will have to wait until Q1 2020, before they receive BIOS upgrades to support Zen 3.

In our Ryzen 5 5600X and Ryzen 7 5800X reviews, we pointed out that they were priced significantly higher than their predecessors.

The AMD Ryzen 9 5950X is priced at $799 (RM3,699) – a $50 (RM550) premium over the last-generation Ryzen 9 3950X, which had a launch price of $749 (RM3,149).

But this time, it comes with a free copy of the upcoming game – Far Cry 6 Standard Edition, which is priced at $56.99.

Paradoxically, this makes the Ryzen 9 5950X the best deal of the Ryzen 5000 series, if you can afford it, of course!

That’s why we believe it deserves our Reviewer’s Choice Award. Congratulations, AMD!

So who should, or should NOT, buy the AMD Ryzen 7 5800X?

  • Buy : If you want the best possible 16-core processor for a new content creation system.
  • Buy : If you are upgrading from a first-generation Ryzen processor.
  • Buy : If you need more computing cores than your current system.
  • Consider : If you are upgrading from a second-generation Ryzen processor.
  • Skip : If you are already using a 3rd Gen Ryzen processor.

 

AMD Ryzen 9 5950X : Price + Availability

The AMD Ryzen 9 5950X processor is available for sale starting 5 November 2020, at these RRP inclusive of tax, in Malaysia :

  • Malaysia : RM 3,699 (~US$889) inclusive of 6% tax
