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.

 

Smart Access Memory For Ryzen 3000 : Requirements

This is what you currently require to enable AMD Smart Access Memory for Ryzen 3000 desktop processors :

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 :

Lead Epic Raids

Lead a crew of raiders and launch lightning-fast surprise attacks against Saxon armies and fortresses. Claim the riches of your enemies’ lands for your clan and expand your influence far beyond your growing settlement.

Engage In Visceral Combat

Unleash the ruthless fighting style of a Viking warrior as you dual-wield axes, swords, or even shields against relentless foes. Decapitate opponents in close-quarters combat, riddle them with arrows, or assassinate them with your Hidden Blade.

Grow Your Settlement

Your clan’s new home grows with your legend. Customise your settlement by building upgradable structures. Unlock new features and quests by constructing a barracks, a blacksmith, a tattoo parlour, and much more.

Share Your Custom Raider

Recruit mercenary Vikings designed by other players or create and customise your own to share online. Sit back and reap the rewards when they fight alongside your friends in their game worlds.

 

Assassin’s Creed Valhalla : FREE With Selected AMD Ryzen CPUs

From 7 July until 3 October 2020, you will receive a FREE copy of Assassin’s Creed Valhalla with the purchase of these AMD Ryzen processors :

Unfortunately, the new AMD Ryzen 5 3600XT does NOT qualify for this great freebie. 🙁

AMD Ryzen XT CPUs : Not Turbocharged But Has Free Game!

AMD just launched three XT additions to the 3rd Gen Ryzen family of processors – the Ryzen 9 3900XT, Ryzen 7 3800XT and Ryzen 5 3600XT.

Here’s a quick comparison of the three new Ryzen XT processors, and how they match up against existing 3rd Gen Ryzen processors!

 

AMD Ryzen XT : Turbocharged? Not Quite…

The Ryzen 9 3900XT, Ryzen 7 3800XT and Ryzen 5 3600XT are higher-speed variants existing 3rd Gen Ryzen processors.

These XT variants are slightly different in their performance and the cooler they come with.

While the XT postfix implied these are turbocharged processors, that depends on the model :

  • 3900XT vs 3900X : 100 MHz faster boost clock + $50 higher price tag, no Wraith Prism RGB cooler
  • 3800XT vs 3800X : 200 MHz faster boost clocks, no Wraith Prism RGB cooler.
  • 3600XT vs 3600X : 100 MHz faster boost clock, Wraith Spire instead of Wraith Stealth

Here is the official tech briefing to  take you through its key features :

 

AMD Ryzen XT : Price + Availability

Here are the official prices for the new AMD Ryzen XT processors, which will be available for purchase starting 7 July 2020.

  • AMD Ryzen 9 3900XT : $499 / ~£397 / ~A$723 / RM 2,299
  • AMD Ryzen 7 3800XT : $399 / ~£317 / ~A$578 / RM 1,899
  • AMD Ryzen 5 3600XT : $249 / ~£198 / ~A$361 / RM 1,199

To sweeten the deal, AMD is offering a FREE copy of Assassin’s Creed Valhalla with every purchase of a Ryzen 9 XT or Ryzen 7 XT processor, from 7 July until 3 October 2020!

Unfortunately, the Ryzen 5 3600XT does NOT qualify for the free game… 🙁

AMD Ryzen XT : Our First Impressions

To be honest, the AMD Ryzen XT processors don’t really excite us that much, and here’s why…

AMD Ryzen 9 3900XT

The Ryzen 9 3900XT has a slightly faster boost clock and loses its bundled cooler. Yet it costs $50 more than the Ryzen 9 3900X.

It would be better to stick with the cheaper Ryzen 9 3900 – you won’t notice the difference. And in case it’s not “fast enough” (seriously?), you can just overclock it.

AMD Ryzen 7 3800XT

This is the second-best Ryzen XT model of the trio, offering a 200 MHz faster boost clock than the Ryzen 7 3800X at the same price point.

You are basically trading the bundled Wraith Prism RGB cooler for a 200 MHz faster boost clock.

Frankly, unless you are planning to use water cooling, it might be a better idea to just buy the Ryzen 7 3800X and overclock using its Wraith Prism RGB cooler.

AMD Ryzen 5 3600XT

This is really the best Ryzen XT model, offering a slightly faster boost clock with a better Wraith Spire cooler, at the same price as the Ryzen 5 3600X.

That makes the Ryzen 5 3600X completely pointless. We wouldn’t be surprised if AMD drops price on the Ryzen 5 3600X, or removes it from the line-up.

 

AMD Ryzen XT : Free Game Changes Dynamics!

AMD’s surprise announcement that they will bundle a free copy of the upcoming AAA game – Assassin’s Creed Valhalla – changed everything.

If you are a gamer planning to buy this game, then it’s a great deal, because the game costs US$59.99 / £49.99 / RM 189.99!

Unfortunately, the Ryzen 5 3600XT does NOT qualify for the free game… 🙁
