Patches scheduled for May and August... I believe it when I see it.
Last time Intel gave patch dates after the big exploit they took three months longer than expected, and then you didn't get them for all the CPUs they originally claimed they'd patch. Way to go m$, quite a track record in 2017/18 so far.

My god,hopefully will not hurt performance... if so that's a big blow indeed.

Somewhere, an Intel engineer is pulling his hair off in frustration.

My guess is that Intel are just gonna have to neuter the branch prediction capabilities of their CPUs even more to fix this, so this is kinda worrying from a performance perspective! I've seen a 10-15% drop in CPU load required in Battlefield 1 since updating to the latest 1803 version of Windows 10, which also coincides with my Spectre protection disappearing (as Microsoft haven't released KB microcode patches yet for 1803) - so this either proves that 1803 version of Windows is a lot more CPU efficient when it comes to gaming or that Spectre protection microcodes can have a 10-15% performance cost to CPU load, in Battlefield 1 at least. The thought of an even more performance impactful microcode being released to kerb these new Spectre threats is less than ideal!

I feel sorry for those guys. This seems to fall under the old adage "Make something idiot-proof and the world just invents a better idiot", except replace idiot's with very clever hackers.

Ouch.

Speculative execution. The gift that keeps on giving.
You know, I always thought computer security was really hard. I now changed my mind. It's impossible.
fantaskarsef
Well it is possible, just not with the design choices around. If speculative execution wouldn't be around, we'd have decreased performance, but not patches needed (in this very single matter though).
The easiest fix for something like this is not to create any exploitable mechanism. I hope that at least in the future this won't happen again... can't wait to see if Intel's next architecture gets equally exploitable features for another 5% performance increase... 😀

How do you think this will effect on EPYC sales?
As I see it those new vulnerabilities month after month brings huge trouble to company's + after patches they loose performance.
prazola
It will hurt performance for sure.

Whenever I see PC security breaches, I'm reminded of Denuvos anti-piracy measures for PC games. Theres only a brief period where the measures can work. Where theres a will, theres a way for hackers to defeat just about anything.
Here I was foolishly thinking my next CPU Zen 2 will be totally secure from these issues, and it probably will.... until the next big exploit or breach is found.

After patching i can expect performance similar to a Pentium 3? 😛
Joking aside, this sucks!

You reap what you sow, or something like that. XD

I hope they got paid well in the past when they didn't need to do much for 10 years. Now they are paying back the karma. In the end it was the businessmen who told the engineers not to do much at all, but I bet now those same businessmen are then telling the engineers to perform miracles overnight.
Didn't Intel report record earnings? Security is overrated. Nobody seems to care in practice.

What's the problem? Switch to AMD.
NSA is a Intel partner 😉

Next year buddy, next year.

Whats the Cheese mean lol?
TheDeeGee
It's the holes in the cheese, as in Intel has holes everywhere.
Venix
i thought we where done with those ...well apparently not ... ^^

Not good at all for them! (intel), Amd was the laughing stock ( Moar cores ) now this.
