A quick look at that expected desktop performance drop after we install the Microsoft CPU Meltdown Vulnerability Patch. Will our test PC drop massively in performance?

Thanks a lot! Not bad then, chispy is this in line with your SSD benches or did you see bigger hits?

It seems on Ryzen systems the performance hit it's bigger than on intel , need to do much more testing. But same as Hilbert findings Storage performance it is where it is more pronounced this performance degradation.
Now let's hope AMD can work with Microsoft to make a new patch to exclude AMD cpu's from this BS and get back our performance. Linux users have already a patch available that excludes them from this performance degradation.
Here: Patch to exclude AMD hit the Linux kernel 5 or 6 hours ago. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=00a5ae218d57741088068799b810416ac249a9ce

I am still doing some NVMe tests on another system as I had an issue with the Samsung 960 pre and post patch results. Will update once the numbers are done.

Good to know,but will be better to test on normal SSD.You know,without fancy wheels like Optane,Nvme.
Not many users have Nvme and the speed on that is already "astronomical".

With everything that has been going on ever since yesterday in regards to the processor bug and the acclaimed up-to 30% performance drops, we decided to grab the new Microsoft patch, install it and tr...
Windows 10 CPU Bug Fix Patch Benchmarks
Thank you for your testing and findings Hilbert. I tested on my Ryzen 1700x / Asus CH VII Hero / Crucial MX300 1TB ssd and i found a big hit in performance in writes and to a lesser extent reads are also affected on my configuration ( Ran Crystal Disk , AS SSD , ATTO and Anvil ). Same PC as yesterday before the patch just tested today with the patch. Trimmed , clean w10 , ran optimized tool between benchmarks and i could not achieve the same scores as yesterday.
Perhaps AMD Ryzen systems are affected in a different way or it might be due to my configuration. But the degradation in performance it is there in the storage department.
