good to see that the performance hit wont be very significant for the majority of users.
Sounds like sloppy work by MS to include AMD in this mess. It's a shame if Ryzen is taking a hit for no reason.
Some of those results are within margin of error, but others have found similar results. If it was margin of error we would expect to see some higher numbers post patch. I think they did wait until patches were available before public disclosure.
What he said^. I appreciate the demonstration that this isn't going to affect my games, but what about a VM host with 10 VM's?
Ummmmm.... In order to full secure your PC you also need to update the CPU firmware.
That patch that Intel provides will be the one that impacts performance in certain workloads. Did you do this before the benchmarks? Because I think you're only benchmarking the windows 10 patch which isn't the patch that impacts performance
8700k here and no difference in FPS.
They already stated the media over rated it to hype it up for hits, also Im not doing shoddy stuff on the internet. The patch could be a spy, good work man!
Hilbert if you can , test an AM4 Ryzen or Treadripper system on an SSD or NVMe. It seems Ryzen systems have taken a bigger hit on performance than Intel. Myself and a lot more members can confirm this by our own testing , it's all over the internet by now that degradation in performance on Ryzen systems is worst and more noticable than Intel.
And it shouldn't even affect AMD's CPUs. If I didn't know MS is full of incompetents, I'd tighten my tinfoil hat and say Intel ordered such an outcome. But since I do know MS is a hive of incompetence, I'll just say they simply didn't know what they were doing, as usual.
MS is incompetents run by Intel
I am kidding. Or am i...
JUst wanted to point out...it appears that the MS KB patch that can be downloaded only install the update but does not activate it. MS has issued client guidance today with some Power Shell script to see what is and what is not enabled from this patch.
MS link here: (Powershell info is at the bottom to check) https://support.microsoft.com/en-us...or-it-pros-to-protect-against-speculative-exe
There are specific conditions where the patch would not all protections would activate, and that is with certain anti-virus software installed. My test rigs do not have that. The page you refer to only shows a few PowerShell commands to verify the patch is active. New firmware, however, might be required, as mentioned in the article. I check/verify this a bit more tomorrow (it's almost 11pm here).
No problem...I was just pointing out a bit more confusion on this in hope you or others would be able to check. Anyhow my Skylake system is enjoying a vacation and I am on my Ryzen build and I am on Win 10 Insider build 17063 so did not get the update nor can I run that powershell command it seems. Get some rest.
Are you running latest bios 1003 for the NVME tests? I've heard a report that the patch is not active before that version, but I don't know if that's true.
My own tests show a 20% drop on the 4k read/write
PC specifications ? That info might help a lot. 20% drop it's a lot.
Intel 900p, 8700K, Maximus X Hero
Given that bench marking an ssd can give very random scores, i know my Samsung pro 960 can vary from 2200 -2500mbs seq read so I think its safe to say that the difference in the bench marks is within margin of error and everyone can stop panicking for the sake of it.
This. We are probably drawing conclusions too soon.
Thanks Hilbert for the tests but as someone already commented, I believe it's a little early to come to any clear and definitive conclusion. We are still missing the firmware patches from the CPU and who know what else...
Also, a test on Windows 7 with more down to earth hardware would be appreciated.
Take some rest and keep up the good work!
I´ll say this here too, using 2600K on W10 and i found nothing to be worried. I got same thing aswell, TimeSpy gave abit better result.
Not everyone is going to see noteworthy performance impact. The large performance impacts are very conditional. Some database software is showing performance impact in the 20%+ range according to Phoronix. It's possible that updates to the most heavily affected software might mitigate some of the performance loss. In any event, security should be more important than performance.
I just tested that on my PC, and I had no performance hit at all for 4K reads and writes. In fact, writes were slightly higher than before the patch.
