Interesting. I don't think there's really that much demand for compute. It's marketing angle.

Slide 9, look at that cost for 7nm double or more than double from 12nm or 28nm.

And it gets worse with 5nm.

They did pretty well keeping the consumer costs low though, seeing where the 2600x and 2700x are listed.

I wish they had gone into more detail on their die stacking plans, but such is life.

90% of these slides have been shown previously, only this time they've got Tuesday's date on them. Sure, one or two slides have slightly updated info, like the 5nm cost one, but everything else is fundamentally the same.

Not much detail on anything really. It's interesting they give broad relevant topics. I kind of feel like a marketing guy made these slides.

The scary cost slide actually wasn't cost per transistor but cost per area, for a 250mm2 die at various nodes. So if this Zen2 chiplet is mass produced/reused in many products the costs should be semi-economical.

Hell, for AMD these Zen2 chiplets are what would have gone in the trash because they're unusable in servers. The quality of silicon making its way to consumers will improve as yields continue to improve at TSMC.

SiSoft benchmark for AMD EPYC 7702P 64-Core Processor (64c/128t @ 3.35ghz)

Spoiler alert: It's a monster.
Seems it triggered the competition today with an all core 4.4GHz, 970 Watt Intel(R) Xeon(R) W-3175X CPU @ 3.10GHz (28C 56T 4.4GHz, 3GHz IMC, 28x 1MB L2, 38.5MB L3)

There are only two systems in the world with a W-3175X that contributed to SiSoft. The other is the one with the 1500W chilled water cooler which goes to 4.8 GHz.
Both systems became active again on SiSoft just before and after the Zen2 launch.

They get a lot more chips out of a wafer. And chiplet design ensures a more efficient die-savaging operation.
