AMD has announced its "Milan-X" Epyc CPUs, which reuse the same Zen 3 chiplets found in "Milan" Epyc CPUs with up to 64 cores, but with triple the L3 cache using stacked "3D V-Cache" technology designed in partnership with TSMC. This means that some Epyc CPUs will go from having 256 MiB of L3 cache to a whopping 768 MiB (804 MiB of cache when including L1 and L2 cache). 2-socket servers using Milan-X can have over 1.5 gigabytes of L3 cache. The huge amount of additional cache results in average performance gains in "targeted workloads" of around 50% according to AMD. Microsoft found an 80% improvement in some workloads (e.g. computational fluid dynamics) due to the increase in effective memory bandwidth.
AMD's next-generation of Instinct high-performance computing GPUs will use a multi-chip module (MCM) design, essentially chiplets for GPUs. The Instinct MI250X includes two "CDNA 2" dies for a total of 220 compute units, compared to 120 compute units for the previous MI100 monolithic GPU. Performance is roughly doubled (FP32 Vector/Matrix, FP16 Matrix, INT8 Matrix), quadrupled (FP64 Vector), or octupled (FP64 Matrix). VRAM has been quadrupled to 128 GB of High Bandwidth Memory. Power consumption of the world's first MCM GPU will be high, as it has a 560 Watt TDP.
The Frontier exascale supercomputer will use both Epyc CPUs and Instinct MI200 GPUs.
AMD officially confirmed that upcoming Zen 4 "Genoa" Epyc CPUs made on a TSMC "5nm" node will have up to 96 cores. AMD also announced "Bergamo", a 128-core "Zen 4c" Epyc variant, with the 'c' indicating "cloud-optimized". This is a denser, more power-efficient version of Zen 4 with a smaller cache. According to a recent leak, Zen 4c chiplets will have 16 cores instead of 8, will retain hyperthreading, and will be used in future Zen 5 Ryzen desktop CPUs as AMD's answer to Intel's Alder Lake heterogeneous ("big.LITTLE") x86 microarchitecture.

Sinistar is a multidirectional shooter arcade game developed and manufactured by Williams Electronics.
Sinistar was the first game to use stereo sound (in the sit-down version), with two independent front and back sound boards for this purpose. It was also used a 49-way optical joystick that Williams produced specifically for this game.

When there can be computer articles/tech news for at least a week or more that don't mention Microsoft and/or Windows in it.
Seriously, fuck Microsoft.

They wrote a good blog post about Milan-X, they have the chips on hand, and they are probably the biggest customer right now.

no news in e-mobility? more doom and gloom in energy sector.

But how long 'til we can actually buy one without handing a scalper an arm and a leg for the privilege of owning a new CPU? It's great to hear what awesome new technology is available... only to later learn that it's not available.
Well, we could at least be happy it's not as bad as with GPUs, maybe we should be thankful for what we got...

No problem with consumer parts. If you mean Epyc, you might have a problem. Guess you'll have to rent it at Microsoft's cloud.

Well, AMD doing good so far. High bandwidth memory together with huge memory size is a necessity for Prolog code.
That's something what ARM, even Apple M1 included, cannot compete with.

Prolog !? It's been a long time since I've heard of that one, The standard seems unchanged since around 2005, so unless somebody's written a *really good* library I don't expect to hear about it again soon (except in this thread).
FWIW, I think even Lisp is better, and that is dying for lack of decent libraries. True, Prolog has some built-in capabilities for formal logic, but that's not really all that useful in the face of combinatorial explosions.
Javascript is what you use to allow unknown third parties to run software you have no idea about on your computer.

SWI-Prolog is found in every self-esteemed FOSS distro for ages. It's free, open source and actively developed for decades, competitive to any commercial Prolog implementation. Its library is huge.
Concerning "combinatorial explosions"... no language is miraculous enough for funny people who can't think while writing code.

It's not for you. In fact, the initial version is not a PCIe card and will be headed straight for the likes of supercomputers:
That's not to say that the PCIe version won't have a similar high power consumption. The new 600 Watt PCIe Gen5 power connector [soylentnews.org] (if it uses it) means they could draw up to 675 Watts.
Basically, MCM is multiple GPUs pasted together. Suddenly doubling the compute/execution unit count while increasing the clock speeds by over 10% results in high power consumption. The TSMC N6 node it's made on doesn't help like N5 would, since N6 only increases density a little from N7.
