AMD Ryzen 7 2700x - Verified 15% performance decrease

[iphorde]

AMD has introduced a performance penalty in their latest update to their AGESA 1.0.0.4 Microcode. This update decreases the multithreaded performance of the CPU by more than 15%.

I have been in contact with Gigabyte and they acknowledged the problem and were able to reproduce the results as well. The performance decrease can be noticed using real world applications and synthetic benchmarks such as Passmark's PerformanceTest.

Gigabyte said they would be contacting AMD about the issue.

I have since tested this on two other motherboard manufactures and found the same result.

Could someone test the Ryzen 5 2600x and see if this penalty exists there as well?

My guess at the moment is a variant of Spectre flaw was patched and has critically hindered the performance and AMD just silently didn't tell anyone.

Other than the fact Gigabyte verified the problem, and I have degrees in Computer Science and with an emphasis in Computer Architecture and was a game developer for years and years. I guess my street cred isn't legit enough anymore.

Yeah, your "cred" is not legit enough here. This is an internet forum and no one knows who you are. There are a lot of people on this forum who's credibility is good. But you made an account on this site 2 days ago and you go on with unsubstantiated claims and recommend short selling stock. Don't be surprised if people ask a few questions.

Yea, probably, I guess you're right. I have tended to get off social media and forums for the past 7 years, but this AMD CPU issue pissed me off so much I couldn't sit around on it.

I'll start contributing, over time, hopefully I'll earn everyone's trust.

sure sec

Also, I found this article, which shows for mainly single threaded games, they also so a performance drop on the 1800x with 1.0.0.4.

i think you should learn enlish...that tast shows performance gain on every game they posted 😵

I thought you had a 1600x.

i dont understand your sentence, please enlighten me a bit, what do you see?

Never mind, I saw the blurry version of the video before youtube had finished encoding it. It looked like a 2 up front.

Are you interested in running a few tests?

anyway...can you show how your ram performs?
lets say in aida 64?
thats the only bottleneck u can expect when agesa changes (unless u get p2 state lock with 2.2GHZ max frequency)

Send me you contact info here:

Ignore the 10 year old website.

Run the benchmarks for yourself and find out.

Do you have some source that verifies your claims? I monitor several tech sites and I have seen nothing of this. This would be a very big story and they have reported nothing. I think your going down a rabbit hole that does not exist.

But your post doesn't show Gigabyte verifying the 15% performance loss you claimed, only that the only changes they from F2 to F3 was the AGESA code. Do you have any other sources verifying the performance loss?

"I would start shorting the stock" - That's not sketchy at all.

Run the benchmarks for yourself. You can do as you wish. Do the work, then run the benchmark, and get back to us. Tell us if you find something different. Make sure you create a baseline configuration for the BIOS and then test each version.

What other source do you want? Do you want AMD to announce they have a big screw up? That would be great.

I want AMD to fix the problem, but they're not responsive. Hopefully this will start getting their attention.

And yes, they did acknowledge the problem. They said use version F2 to get the best performance.

So I run a performance lab and I cannot recreate this issue. Also, we are saying that Gigabyte is aware. Can I ask who you spoke to at Gigabyte none of my engineering contacts will verify this claim. I want to help and have the ability to help but I cannot seem to verify these claims.

There are some claims that newest W10, 1809 lowered performance by 10% but I'm running Skip ahead 1809 and couldn't verify that either. all runs as usual or at least same benchmark scores. Linux Mint doesn't show any different.

I don't personally have a AM4 system, but this seems bad if true
