Well done with the humour!

You slay me, Timothy, you really do!

But not in the two-socket space where AMD is playing.

“AMD has been meeting or beating Intel’s performance per socket and, at list price at least, cleaning its clock cycles on bang for the buck with the Rome lineup compared to Cascade Lake, and we don’t think that gap is going to change much.”

I’m saying … you compare to Cascade Lake, as if there were no Cooper Lake. Cooper Lake did make big changes … doubling the UPI bandwidth, adding bfloat16 processing to double the ai training performance vs fp32.

We covered Cooper Lake, too. And that was last year. This was about this year coming up.

Those chips doubled the UPI bandwidth in the 4 socket design. They also support up to 18TB of memory per node, including the Optane DIMMs.

So … just curious why no mention of Cooper Lake in this article.

Also … Facebook specified the avx512 bfloat16 requirement for their Zion platform and Intel delivered in Cooper Lake.

Yes, I knew that and just fixed it.

It is the software ecosystem that pushes hardware further upscale as successful companies grow. For open source it is the entry-level hardware market share that drives the software development.

While I understand it’s crucial for IBM to protect established high-end customers with an upgrade path, Red Hat is not an island but instead tightly interlinked with many independent open source projects. Leaders of those projects need to be convinced that Power10 is relevant by market share in order to focus any effort on optimising for that architecture.

Maybe the tapeout of a new design at a new foundry will result in great yields. However, just like the student who aspires for a B grade often fails the course, I think expecting one core out of 16 to be defective on each chip is destined to lead to many chips where less than half the cores work. If so, maybe be those yield problems could be turned into new market share for cost-effective 6 and 8-core workstations.
