Smart Access Memory Now Enabled For Ryzen 3000 CPUs!

Smart Access Memory Now Enabled For Ryzen 3000 CPUs!

AMD just enabled Smart Access Memory for select Ryzen 3000 desktop processors!

Find out what Smart Access Memory does, and how to enable it for a FREE boost in performance!

 

Smart Access Memory Now Enabled For Ryzen 3000 CPUs!

When AMD launched the Radeon RX 6700 XT graphics card, they also mentioned that Smart Access Memory is now enabled for Ryzen 3000 desktop processors, except :

  • AMD Ryzen 5 3400G
  • AMD Ryzen 3 3200G

This would give those older processors a small but FREE boost in performance, when paired with Radeon RX 6000 series graphics cards and AMD 500 series motherboards.

To enable Smart Access Memory for your Ryzen 3000 / 5000 series PC, please follow the steps! 

Unfortunately, AMD has not enabled Smart Access Memory for Radeon RX 5000 series graphics cards, or AMD 400 series motherboards yet.

Smart Access Memory : How Does It Boost Ryzen 3000 Performance?

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 Ryzen 3 3300X Review : Quite The Bargain @ $120!

The AMD Ryzen 3 3300X is more than just a slightly amped version of the Ryzen 3 3100. And it is quite the bargain at $120!

Find out why we gave this new AMD Ryzen 3 processor our Editor’s Choice Award!

 

AMD Ryzen 3 3300X : Official Tech Briefing

Let’s start with the official AMD Ryzen 3 3300X tech briefing by AMD Ryzen Product Marketing Manager, Erin Maiorino.

 

AMD Ryzen 3 3300X : Key Features

The AMD Ryzen 3 3300X is a quad-core processor, with a 3.8 GHz base clock, and a 4.3 GHz boost clock.

It supports SMT (simultaneous multi-threading), and can therefore handle up to 8 threads at the same time.

New Chiplet Design

Unlike the previous Zen and Zen+ microarchitectures, Zen 2 uses a chiplet design that combines separate CPU chiplets with an I/O chiplet, using Infinity Fabric to connect them.

This chiplet design allows the performance-critical CPU chiplet to be fabricated on the 7 nm TSMC process, while the I/O functions are fabricated on the less expensive 12 nm GlobalFoundries process.

The new I/O chiplet adds PCIe 4.0 support, offering 24 lanes that can be increased to 40 lanes, when paired with the new AMD X570 motherboard.

4+0 CCX Configuration

Unlike the Ryzen 3 3100, the Ryzen 3 3300X uses a 4+0 CCX configuration. That means it uses a single CCX (Core Complex).

Its four cores directly communicate with each other, and share the same 16 MB L3 cache, allowing it to deliver better performance with lower latencies, than the Ryzen 3 3100.

TDP + Bundled Cooler

The AMD Ryzen 3 3300X has a 65 watt TDP, which can be reduced to 45 watts using Ryzen Eco Mode. And it comes bundled with the Wraith Stealth cooler.

Socket AM4

The AMD Ryzen 3 3300X continues to use the AMD AM4 socket, and is backward compatible with AMD 400 Series motherboards, as well as the new X570 and B550 chipsets.

AMD Ryzen 3 3100 : 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.

Will you look at that? The AMD Ryzen 3 3300X is actually 9.6% faster than the Intel Core i7-8700K, and 18.7% faster than the Ryzen 7 2700X in single-core performance!

CINEBENCH R20 Multi Core Performance

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

Of course, the 3300X is still a quad-core processor, which means it will not perform as fast as 6-core processors, or 8-core processors.

Even so, it was actually as fast as the Ryzen 5 1600X (6 cores), and 72% as fast as the Ryzen 7 1800X (8 cores).

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.

While it may appear that the Ryzen 3 3300X has superior SMT (Simultaneous Multi-Threading) capabilities to the Intel Core i7-8700K, this is due to the fact that all four cores are in the same CCD (Core Chipset Die).

And it appears to have lower MT boost than the Ryzen 3 3100 because of its significantly better single-core performance.

 

AMD Ryzen 3 3300X Video 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).

Despite having only four cores, the Ryzen 3 3300X was 89% as fast as the Ryzen 5 1600X (6 cores), and 75% as fast as the Ryzen 7 1800X (8 cores).

In other words, it was 30% to 45% more efficient per core, than both first-gen Ryzen processors.

 

AMD Ryzen 3 3300X 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 CC 14 using a single 13.5 megapixel photo, with a filesize of 4,910,867 bytes.

Despite being a quad-core processor, the AMD Ryzen 3 3300X actually beat  the Ryzen 5 1600X, a 6-core processor!

It is notable in this test that it is 18.5% faster than the Ryzen 3 3100, very likely due to its 4+0 configuration.

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 3 3300X was 7% faster than the Ryzen 3 3100, and just 14% slower than the Ryzen 5 1600X.

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.

Ultimately, it was just 2% faster than the Ryzen 3 3100, and only 3% slower than the Ryzen 5 1600X or Ryzen 5 2600X!

Time Spy Extreme – 3840 x 2160

At the higher 4K resolution, the AMD Ryzen 3 3300X was 9% faster than the Ryzen 3 3100, and 6.7% slower than the Ryzen 5 1600X.

Now check out the processors’ effect on the overall gaming score…

At 4K, it was virtually as fast as the Ryzen 5 1600X, edging out the Ryzen 3 3100 by just 2%.

 

F1 2019

F1 2019 is a relatively recent racing game by Codemasters, released on 28 June 2019.

We tested it on three resolutions at the Ultra High settings :

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

1080p Gaming Resolution

Will you look at that! This is why the number of CPU cores don’t really matter when it comes to games.

The cheap Ryzen 3 3300X delivered average frame rates on par with the 8-core Ryzen 7 2700X!

1440p Gaming Resolution

At the higher 1440p resolution, the importance of CPU performance was greatly reduced. It didn’t matter which processor you used – they all delivered about the same frame rates.

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
  • 1440p : 2560 x 1440

1080p Gaming Resolution

At 1080p, the AMD Ryzen 3 3300X performed as well as the 8-core Ryzen 7 2700X, and was 14.6% better than the Ryzen 3 3100.

1440p Gaming Resolution

When we bumped the resolution up to 1440p though, it really didn’t matter that much which processor you used.

 

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

1080p Gaming Resolution

This showcases the importance of the Ryzen 3 3300X’s greatly-improved single-core performance. It actually delivered 23% and 24% better frame rates than the Ryzen 7 2700X and Ryzen 5 2600X processors!

1440p Gaming Resolution

At the higher 1440p resolution, the Ryzen 3 3300X was 20% and 28% faster than the Ryzen 7 2700X and Ryzen 5 2600X processors!

 

AMD Ryzen 3 3300X : Our Verdict + Award!

Built around the Zen 2 microarchitecture, the AMD Ryzen 3 3300X uses a chiplet design which combines 7 nm and 12 nm parts to deliver a more powerful, and power-efficient processor at a great price point.

The end result is significantly better single-core and multi-core performance over previous generation Ryzen processors.

 

Overall, the AMD Ryzen 3 3300X is roughly equivalent to the Ryzen 5 1600X, a first-gen 6-core Ryzen processor. In some benchmarks, it is perhaps 10% slower, and yet it is equal or faster in other benchmarks.

At first glance, the AMD Ryzen 3 3300X may seem to be an amped-up Ryzen 3 3100, but its 4+0 configuration does confer it additional performance benefits above and beyond its higher clock speeds.

Now if you do a lot of 3D or video rendering, you should definitely get something like the Ryzen 7 3700X with 8 cores and 16 threads of processing power.

But if you want something cheap to power a gaming system, the Ryzen 3 3300X is a great, GREAT option. The money you save can go towards a better graphics card!

And we should point out again that this 4-core, 8-thread processor only costs US$120 / RM 549, and it’s bundled with a Wraith Stealth cooler to boot!

While not quite the steal that the Ryzen 3 3100 really is, it is still a darn good bargain. So we are giving it our Editor’s Choice Award too!

 

AMD Ryzen 3 3300X : Where To Buy?

The AMD Ryzen 3 3300X has a launch price of US$120 / ~£97 / ~A$190 / ~S$172 / RM 549..

AMD Ryzen 3 3300X vs Ryzen 3 3100 Comparison

Now that the first two 3rd Gen Ryzen 3 processors are out, here is a quick comparison of the AMD Ryzen 3 3300X and Ryzen 3 3100 processors!

 

AMD Ryzen 3 3300X vs Ryzen 3 3100 : Official Tech Briefing

Let’s start with the official AMD Ryzen 3 3300X and Ryzen 3 3100 tech briefing by AMD Ryzen Product Marketing Manager, Erin Maiorino.

 

AMD Ryzen 3 3300X vs Ryzen 3 3100 : Comparison

Cores + SMT

They are both quad-core processors that supports SMT (simultaneous multi-threading), so they both can handle up to 8 threads at the same time.

CCX Difference

While they are both quad-core processors using a single CCD (Core Chipset Die), AMD configured both processors differently.

The Ryzen 3 3300X uses a single CCX (Core Complex) – its four cores directly communicate with each other, and share the same 16 MB L3 cache. AMD calls this a 4+0 configuration.

The Ryzen 3 3100 uses two CCXs with two cores in each CCX, sharing their own 8 MB L3 cache. The two CCXs communicate through the Infinity Fabric interconnect. This is known as the 2+2 configuration.

This difference has performance implications – Ryzen 3 3300X will deliver better performance with lower latencies, than the Ryzen 3 3100.

Clock Speed Difference

To further differentiate them, the Ryzen 3 3300X has a 200 MHz (5.55%) higher base clock and a 400 MHz (10.25%) higher boost clock.

TDP + Bundled Cooler

They both have a 65 watt TDP, which can be reduced to 45 watts using Ryzen Eco Mode. They also come bundled with the Wraith Stealth cooler.
