It seems on Ryzen systems the performance hit it's bigger than on intel
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.

im sorry but those test before and after look like there within "margin" of error
tell said people that response able for the flaw and fixing to fix it they have till so and so time to do so or this info will be released
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.

The wolves are gonna be in cluster virtual machine environments, not for +/- 2% on futuremark.
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.

So I only performed one test on my system, and I would say that I get like 10% worse performance.

Core i7 2600K at 4 GHz, samsung 850 EVO ssd. The test is, in a ConEmu terminal under Windows, under Bash (from git-bash), I type this:


Weasis compilation:
Before patch: 53 seconds
After the patch: 105 seconds

Weasis is a Java viewer for X-Ray, CT-scan and CAT-scan file formats. This ConEmu + MinGW + bash + Maven + javac scenario probably touches quite a few different aspects of the operating system, from file access, to lookup, writes, compilation, the (few) Weasis tests, etc. I tested by restarting the computer, opening ConEmu and running the clean + install cycle 5-6 times until it stabilized.

Nobody cares!!!!!

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.
