Meltdown slowing computer!

[Anthony_195]

I feel like my computer is slower now after the meltdown patch from windows. I have the i7 4790k. Also my friend said the same. I’ve seen SYS system responsiveness benchmarks that show 30%slowdown on that particular benchmark for i7 6700k and my cpu is even older! Is ryzen a more compelling platform or should I remove the windows updates to a previous point?

You'll get the same meltdown Windows updates even if you have a Ryzen computer. So if you believe the patch slowed down your computer, it would slow down everyone.

I don't know where you found those benchmarks, but the vast majority show a 2-5% performance hit to modern intel CPU's (and by modern, I mean anything from Sandy Bridge (2xxx) onward).Odds are, if you're experiencing noticeably slower performance, something else is involved.

AMD chips aren't hit as hard because they have a different implementation of predictive execution, yes, but the hit to intel CPU's newer than Nehalem is not that huge.

Actually Ryzen's Meltdown issue wasn't hardware related. It was software related and patched by AMD ahead of time. Many sources state because the way Ryzen was effected and fixed. It wont notice those slow downs. Only Intel CPUs would because it is a software patch to a physical design issue, hence more overhead. AMD uses another propriety technology to transfer between the cache and that technology is already encrypted. So effected by the same issue with two different fixes and results due to different design infrastructures.

I've recently read an article that stated they believe Intel found a way to fix the problem without having the slowdowns. However, its still in testing and hasn't been released yet. So if you have an Intel CPU, your only real option is to wait.

The slowdown shouldn't be noticeable to anything 4th gen (Haswell) or newer, as those CPUs were designed to handle that extra overhead. I have the i7 4770k, which is the step down from yours, and have seen no performance loss.

Have you checked the RAM clock? Sometimes an OS update will do stuff to the way the Motherboard handles RAM (my desktop slowed suddenly one day, and I discovered the issue being a 1333 clock, when I expressly set up the maximum stock 1600 clock. I changed it back and it's been smooth sailing ever since).
