Any data on older processors? For example I run a sandy bridge 3930k but didn’t see anything? Also how far back are they going to patch?

Is SB going to remain unpatched? Those systems are still perfectly fine for consumer use. I hope business starts selling them off cheap.

“users who use web applications that involve complex JavaScript operations may see a somewhat higher impact (up to 10 percent based on our initial measurements).“ Ok so that’s probably most websites these days?

I have to say I am pretty PO'd regarding this. A month ago I JUST finally bought a nice new i3-7100 PC to replace my 10yo Core2Duo for Christmas. Office tasks, web games for kid, work, etc.

I have measurably noticed the decrease in speed in various web benchmarks. Enough to make it feel like I was mislead in what I thought I had purchased. I wrote down two tests I did the day I first brought PC home and have run them many times since the first patches hit Windows 10. I got two clear hits - A small hit with the Windows 10 patch, then another hit with the PCU microcode update (through a BIOS update released by Lenovo).

Windows10 x64 1709

Edge: Jetstream: 271 in Dec, 246 today. -9.2% MotionMark: 307 to 245. -20%!

Firefox: Jetstream: 199 In dec on FF-57, 175 today FF-57.0.4. -12%

That is bad enough to me that I would just take this PC back to store for money back if it was still within return timeframe. I'd rather just wait for this to be fixed at the hardware level now or wait for a Zen APU in a few months. Imagine you bought a car a month ago and today got 9-20% LESS horsepower because of a "Fix".

I can only imagine how upset cloud providers must be at this. Or any company needing every ounce of CPU performance they paid for. AutoCAD farms/rendering comes to mind.

I hope there is a class action lawsuit for anyone who bought Intel CPU's. Obviously pro-rated by how long ago you purchased. I'd definitely sign up at this point for some $ back. Problem is it will only be like $5 in my pocket after lawyers get their payday.

Looks like Sandy Bridge is going to remain unpatched. That doesn't mean that your OS, compiler and so on won't get updates though.
