New The PC Build Thread


Zen 5 bug is also a Zen 4 bug ;)

As also remarked, this could impact other CPUs too.

NOTE: This workaround still produces mixed results. In some instances Zen 5 and Zen 4 scale the same, but in some other instances Zen 5 wins by quite the margin though Zen 4 also wins in some cases. As then observed, this admin workaround is not a solution, there is more to the issue.

Looking a lot better than it did previously.
 
Bought one to try it, does like to boost all the time :P

Was first time post, no isssues with XMP or any BSOD.

Using msi Pro B650-S wifi, cheap board was on special at suppliers for 2500 ex vat

So does everything else. Zen 4 is the AM5 baseline. You can only really compare Zen 5's behaviour to Zen 4 in regard to expectations. Zen 5 'bugs' could also theoretically be Zen 4 'bugs'. Percentile improvements will remain the same, but not the numbers promoted by AMD.

Zen 5 is an improvement, but there are issues with AM5, and AMD needs to iron it out.

The issue with Windows, it is likely impacting Intel too.
 
A change which is made to the 870 series motherboards are the power stages. At Computex Asrock seemed a bit insane with their upgrades, but now I see it with Asus too. Asus did not upgrade all boards, but the mid to lower tiers have had increases and improvements to its power stages. This is applicable to the TUF, ProArt and Prime, but I think that the Strix might also have had a slight upgrade in quality as the heatsinks seem larger. There might have been revisions made to the power design. I won't know, would have to see the boards. Pictures can be misleading.

This said, the TUF, ProArt and Prime also seem to have a dedicated chipset heatsink. I know that some reviewers complained about the temps on the 670 TUF.

Just an interesting observation.

Options, uhm option.

MSI also teased their new 870E Carbon WiFi today. Power phases also look improved, but I can't say since they don't build their marketing around it like Asus and Asrock do.

The 600 series boards are still being supplied. Pricing might bite some considering the 800 series until the 850 drops.

Ryzen 9000 Series Community Update: Gaming Performance​


The new “Zen 5” architecture first introduced in high end laptops earlier this summer is now available in a full stack of desktop processors with the AMD Ryzen 9000 Series. And while “Zen 5” is delivering leadership performance across content creation, productivity and AI applications, we’ve heard from the community that they, with good reason, expected even more gaming performance from Ryzen 9000 Series than initial reviews show.

Community feedback is very important to us, and we have two relevant updates for you today:
  • Why AMD-generated gaming data differs from reviewer data: For our Ryzen 9000 launch, AMD internal labs generated data that showed a 9% average generational uplift in 1080P gaming versus Ryzen 7000 Series, and an average of 6% higher performance across more than 30 games when compared against the competition’s best. Not all reviews are seeing these results, and this reflects the complexity of high-performance PC testing today given the number of system and software variables. There are several factors specifically creating these differences in some Ryzen 9000 reviews:
    • The AMD gaming test suite includes a broad set of esports, AAA, and popular older games, which are a combination of CPU- and GPU-bound titles. Game performance conclusions can be influenced significantly by the makeup of the test suite.
    • AMD tested Intel configurations using comparable DDR5-6000 memory as well as Intel default settings-baseline power profile which can have a small impact on gaming performance.
    • AMD also tests with Windows Virtualization-based Security (VBS) enabled. This is the default Windows behavior and Microsoft recommends activating VBS to improve security, however it can affect gaming performance.
    • The “Zen 5” architecture incorporates a wider branch prediction capacity than prior “Zen” generations. Our automated test methodology was run in “Admin” mode which produced results that reflect branch prediction code optimizations not present in the version of Windows reviewers used to test Ryzen 9000 Series. We have a further update on accessing this performance for users below.
In light of this, the Ryzen 9000 Series delivers leadership performance across content creation, productivity and AI applications. On a generational basis, Ryzen 9000 Series delivers a ~10% improvement in productivity and creative workloads, ~25% improvement in AI workloads, and 5-8% improvement in gaming over the Ryzen 7000 Series.

When comparing to the competition using optimal settings, higher memory speed and extreme power delivery profile for the competition and Windows 11, version 24H2 for both (see details below), we see a double-digit lead for Ryzen 9000 Series in productivity and creator applications, ~30% lead in AI workloads, and parity in gaming using the most popular games included in the reviews.
  • Further enabling advanced “Zen 5” architecture: For “Zen 5” users, here is our recommendation for how to unlock the best performance. Optimized AMD-specific branch prediction code will be available in Windows 11, version 24H2 in preview through the Windows Insider Program (Release Preview Channel - Build 26100) or by downloading the ISO here. While performance will vary based on the application and configurations, below is a sample of what you can expect to see with 24H2 on Ryzen 9000 desktop processors:

Game performance shown as average FPS, 1080p High

"Zen 5" will see the biggest boost, but this Windows update will improve performance for "Zen 4" and "Zen 3" as well. We're collaborating with Microsoft to roll out this optional update to all Windows 11 users soon.

We also want to acknowledge and thank the reviewer community for all their testing and feedback. Many of their observations are helping accelerate our work developing future AMD Ryzen firmware updates that will benefit Ryzen 9000 users. We also want to hear from the community on your experiences with Ryzen 9000 series. As we have done with every new architecture, we will continue to use community and press feedback to tune and optimize and deliver the absolute best possible performance to Ryzen customers.

Wendell shared his mind:


According to him, Zen 4 is not impacted by VBS in the same manner as Zen 5. He still needs to explain his oddities with Zen 4 comparative scores... I mean he got 1706 in multicore with a 7950X, and never cleared that up. Anyhow, in his view, in the instance the anomalies are solved in Windows then Zen 5 will have a massive boost in some cases, using Linux as a benchmark.

I see "Team Red" is already piling on Hardware Unboxed.

So, I don't know, perhaps the situation is true with Zen 5.
 

ASUS debuts its “NitroPath” DRAM tech with its ROG Crosshair X870E Hero motherboard​


...

As DRAM speeds increase, signal integrity is becoming an increasingly important factor. That’s why ASUS have redesigned their DDR5 DRAM slots with new “NitroPath” technology to reduce noise and boost memory speeds.

Not only does these new DRAM slots promise higher levels of signal integrity, they also promise increased retention force. DRAM modules will be secured with 57% more retention force. Additionally, ASUS has reported up to 400 MT/s higher DRAM speeds.

With their new NitroPath DRAM slots, gold finger pins are 39% shorter. The highlighted areas of conventional DRAM slots are where ASUS claims that noise levels are highest. With their new NitroPath design, this area is effectively done away with. With this change, ASUS claims to have delivered a near 40% reduction in noise.

Now we are getting somewhere with enhancement that will have a true impact. The issue though, even improving it at a hardware level, parameters would have to adapt to take advantage otherwise the results will remain the same as the current.

Voltages should improve, and it is this headroom which will allow better overclocking. It still comes down to the memory, and not the motherboard per se. Not all memory, even those rated the same, behaves the same. Just like CPUs and GPUs.
 
Since GamesCom, Asus have been hyping up the 870/E motherboards. They said that release is imminent, but that it is region pending, and hence can't give any pricing. From what I have heard these boards are pushed back to October, but may have been distributed in some quantities. I can't say, won't know.

AMD X870E motherboard reviews expected on September 30 - VideoCardz.com​

First AMD 800-series motherboards launching late September​

After a full showcase at Gamescom, companies are now preparing for the launch set for next month.

...

I’ve finally received the new X870 series motherboard, which is designed to work with the AMD Ryzen 9000 series processors. According to AMD’s official schedule, on August 20, 2024, I can only do an unboxing and provide a basic overview of the specs without powering it on. The embargo on sharing any actual usage experiences lifts on September 30, 2024, so please don’t ask for any performance insights before then.

Videocardz don't always report accurately, but at times they can be reliable. It is still a long wait, and it seems that the go-to-market plan is October, within Intel's launch window. I don't care much about it being delayed since I am in no hurry and October is soon enough.

For those wanting to buy a new, latest generation, system, wait until mid-October/November. See how the market reacts. Zen 3 and older peeps might consider upgrading, and Intel might take migration under consideration. The upcoming Intel CPUs does not look too bad, it will be the same as with Zen 5, perhaps without the existing Intel issues.
 
The Windows 23H2 'bug' which is squashed in Windows 24H2, or otherwise Zen 3/4/5, optimisations, does not seem to bode Intel any good. <More testing required, cherry-picking can sway perception>

Given the above screenshots, there goes Kitguru's cynical remark:


I am sure that there will be more optimisations, more so in regard to core handling.
 
There are claims that the 9950X has dethroned the 7800X3D in 24H2. It is uncertain to say whether this is true. At this time it is best to see results produced by reliable and trusted reviewers.

7800X3D gets as much benefit from 24H2 as Zen 5. So while there might be game specific advantages. The cache is still massive for some games.
