the new SAP optimized hardware is like made for snowblossom :stuck_out_tongue: https://www.anandtech.com/print/14152/lenovos-new-cascade-lake-thinksystem-servers-up-to-8-sockets-with-optane Lenovo’s New Cascade Lake ThinkSystem Servers: Up to 8 Sockets with Optane

not in any sane price range for years to come, though

and these are getting interesting as well, just not for snowblossom https://www.anandtech.com/print/14149/intel-agilex-10nm-fpgas-with-pcie-50-ddr5-and-cxl Intel Agilex: 10nm FPGAs with PCIe 5.0, DDR5, and CXL

and the red carpet for the deep future of arktika is also getting rolled out https://www.anandtech.com/print/14148/intel-columbiaville-800-series-ethernet-at-100g-with-adq-and-ddp Intel Columbiaville: 800 Series Ethernet at 100G, with ADQ and DDP

and it's so silly a RAID of consumer SSDs will outperform the high end enterprise storage :stuck_out_tongue: https://www.anandtech.com/print/14158/intel-announces-new-optane-and-qlc-enterprise-ssds Intel Announces New Optane And QLC Enterprise SSDs

and last spam of the burst, up to 4.5TB direct-to-cpu optane per socket https://www.anandtech.com/print/14146/intel-xeon-scalable-cascade-lake-deep-dive-now-with-optane The Intel Second Generation Xeon Scalable: Cascade Lake, Now with Up To 56-Cores and Optane!

so what the burst above is about, is intel having announced its current gen 'Xeon E7' platform (in ye olden speek)
2019-04-02 22:10:37
mjay
56 cores, 400W tdp, in one package

Xeon Platinum 9282* 56cores 2,6 / 3,8 GHz 77 MByte cache 400 W

400w

they seem to be under heavy pressure. Same architecture, same power efficiency, just put more cores on a chip and try to sell it
2019-04-02 22:27:18
mjay
8180 was 28 cores 205W with slightly higher clock speed even
2019-04-02 22:30:38
mjay
how do you cool 400W? Water cooling?
2019-04-02 22:31:01
mjay
higher max. temperature maybe?
2019-04-02 22:31:05
Rotonen
well, it is a big chip

i remember when some internet humorist did a linear extrapolation of the energy densities of CPUs around the time of the intel netburst architecture (pentium 4), and pointed out that we'd exceed the energy density of the core of our sun before 2012 at that rate :stuck_out_tongue:
2019-04-02 22:32:49
Rotonen
for cooling, the problem is reducable to power over area as per some symmetries involved
2019-04-02 22:33:03
Rotonen
otherwise it'd be power over the volume, but therein lies magic not easily explained
2019-04-02 22:33:30
Rotonen
but i do not think they'll be able to get sellable yields at larger chip sizes, wafer sizes are also stagnating
2019-04-02 22:33:50
Rotonen
and EUV lithography is the fusion power of the semiconductor world, always just around the corner
2019-04-02 22:34:28
Rotonen
so the third(?) wave of bruteforce by hardware is at an end, as far as i can see
2019-04-02 22:34:55
Rotonen
now people just have to get clever in the below-ring0 software (as in execution pipeline magic, as in exactly the stuff which already landed us in hot water with spectre and friends)
2019-04-02 22:35:38
mjay
Maybe we'll soon see some new architecture, fpga integrated into cpu maybe?
2019-04-02 22:36:24
Rotonen
well, heterogenous multiprocessing architectures are already in your pocket and thus widely used in production
2019-04-02 22:37:18
Rotonen
and intel stratix is already a mature platform, they renamed it to agilex now for whatever reason, but you can have had a cpu/fpga/hbm stack for years now

they have a purchasing wizard on their site upon curiosity https://www.intel.com/content/www/us/en/programmable/buy.html

unrelatedly, let’s see if nethash starts sustaining over 4G now http://snowblossom.hamster.science/munin/hamsterpool/hamsterpool/snowblossom_nethash.html

I've been quiet recently because I am launching an unrelated commercial venture.
