Which Intel CPU generation will have hardware fixes for these Spectre variants?
According to what we're seeing, the situation seems to be reversed with the 3xxx series, where AMD seems to have a small but significant lead; we'll have to wait for independent benchmarks.
They aren't competition if they fall of the map. So a slightly edge would be great because it at least puts them back in the game.
This is easy to prove. The highest clock rate xeons you'll find are a special SKU exclusive to aws. Sure enough, they have far fewer cores than instances with lower clocks.
What you're seeing isn't routing issues, but the fact that their newer process isn't up to snuff, and they don't have the proper yields on larger die sizes.
Like, I've shipped RTL and know pretty well how this stuff works.
It certainly looks promising, but I'll still hold my excitement until we get some 3rd party benchmarks.
I'm also skeptical of first party benchmarks, but I'm already pretty excited that I finally might be able to justify an upgrade from my old haswell setup.
In a cloud you typically pay for cores from a specific CPU type. Presumably any clouds at offer AMD cpus will price them in a competitive manner.
I mean, the cloud business is the place with the most to lose from these kinds of issues, I am incredibly suspicious of the claim that cloud providers aren't patching their microcode.
Whether it's intels or their own modified variant of microcode I would fully expect them to be patched in some way.
They have much to lose from not applying these mitigations, especially if they're the people spending a fortune to find them.
I honestly doubt that claim however and haven't heard it before this thread.
