Intel announces Cascade Lake Xeons: 48 cores and 12-channel memory per socket
Intel has announced the next family of Xeon processors that it plans to ship in the first half of next year. The new parts represent a substantial upgrade over current Xeon chips, with up to 48 cores and 12 DDR4 memory channels per socket, supporting up to two sockets.
These processors will likely be the top-end Cascade Lake processors; Intel is labelling them "Cascade Lake Advanced Performance," with a higher level of performance than the Xeon Scalable Processors (SP) below them. The current Xeon SP chips use a monolithic die, with up to 28 cores and 56 threads. Cascade Lake AP will instead be a multi-chip processor with multiple dies contained with in a single package. AMD is using a similar approach for its comparable products; the Epyc processors use four dies in each package, with each die having 8 cores.
The switch to a multi-chip design is likely driven by necessity: as the dies become bigger and bigger it becomes more and more likely that they'll contain a defect. Using several smaller dies helps avoid these defects. Because Intel's 10nm manufacturing process isn't yet good enough for mass market production, the new Xeons will continue to use a version of the company's 14nm process. Intel hasn't yet revealed what the topology within each package will be, so the exact distribution of those cores and memory channels between chips is as yet unknown. The enormous number of memory channels will demand an enormous socket, currently believed to be a 5903 pin connector.
Intel also announced tinier 4-6 core E-2100 Xeons with ECC memory support.
Meanwhile, AMD is holding a New Horizon event on Nov. 6, where it is expected to announce 64-core Epyc processors.

...OLD THING...IN A DIFFERENT BOX!
Is anyone else almost pitying how pathetic Intel is looking this past year? Yes, of course, they still are by far the dominant player compared to AMD, but as far as optics go, it seems to have been failure, after security disclosure, after failure, after disclosure, after failure.

This is the second time in the last few months that Intel has frantically tried to divert attention from AMD's own product announcements:

Competition is fine, but what we've gotten from Intel are expensive, hot [tomshardware.com] distractions.
How hot is this thing going to run? Why couldn't they glue two of their 28-cores together?
It's funny that they compare it to the previous generation Epyc the day before the new Epyc will probably be announced. 240% faster in certain workloads (hot-running AVX-512 I guess). Except AMD is probably going to double the core count and increase per-core performance by maybe 25% (+10-15% IPC + clock speed increases), resulting in a theoretical 150% performance increase for Epyc.
With that said, we can praise Intel for following AMD and using multiple dies to increase core counts and get around bad yields. We knew it was coming, and it's the smart move.

Would mod up +1 Insightful...or maybe +1 Funny for the "hot distractions" bit, that made me chuckle. I was almost thinking it would be a link to their Computex incident with the standalone AC unit. So surreal, and strangely satisfying, to see the titan falling. I'm sure it will catch itself before long, but for now I'm content to watch....and invest a little in AMD. I bought at $12/share.

It's included in the "Intel Teases 28 Core Chip, AMD Announces Threadripper 2 With Up to 32 Cores" link, but I also alluded to it in this story:

YES, they are still trying to catchup with IBM Power series.
We been multiple cored for years, with up to 16 "chips" on a single motherboard with 1TB per 4 chips/// that was 2002!

I distinctly remember a 2006 Intel press blitz about "80 core processors... coming soon!"

Could have been, although a lot of the 2006 press flak made it sound like they were 80 parallel GPCPUs, not GPGPUs.

Oh yeah, well just you wait! Intel is still leading the way in innovation, and only a couple of years behind schedule.
They will be rolling out 10 nm any
daymonthyear now!
