Nadolazeći AMD socketi, ploče i procesori

[Manuel Calavera]

Odličan video. Pogotovo ove info o steppinzima, te "high availability" sredinom 2019. Taj 7nm je stvarno "next big thing" od trpanja abnormalnog broja jezgri u serverima, do brutalne efikasnosti u low power segmentu

oDkud ti ovo o IPC-u?
ne mogu nigdje naći neki trag o tome...?

Evo jedan od linkova, a obzirom da sad skoro svi prate jedno-te-istu stvar, bude se na kraju sve skupa iskristaliziralo.

Process migration has allowed AMD to double chip density by 2X, halve power consumption, and deliver claimed boost in overall performance by 25 percent compared to its previous gen Zen+ architecture.

U međuvremenu:

• 02:20PM EST - Rome is PCIe 4.0
  
  
• 02:20PM EST - Socket compatible with Naples
  
  
• 02:20PM EST - Up to 64 Zen 2 cores, 128 threads
  
  
• 02:19PM EST - Preview of Rome

25% performance, ne IPC. Tih 25% je IPC + takt, a brojke vezane samo za IPC su dosad bile 13-15%.

Zato i velim da treba pričekati da se sve privede kraju, jer su zasad završili s prezentacijom, slijedi još demo tih novih čudesa.

Uglavnom, 7nm Zen 2 64C/128T Rome EPYC CPU (8-core CCX) izgleda obećavajuće i za ostatak (desktop) ponude.

Zen 2 is a departure from the monolithic CPUs that, while bringing the aforementioned density, power, and core configuration gains, also introduces a design concept which both AMD and Intel have been gushing about for a few years now: a modular CPU built on an interconnect (Infinity Fabric) linking multiple CPU chiplets (in this case, the CCX). In Zen 2, each 7nm chiplet contains 8 physical cores and sits on a second gen Infinity Fabric interconnect (built on a 14nm process), connecting the CCX clusters. This enables AMD to add increased flexibility to the CPU designs and, eventually, roll out lower-ranking SKUs such as a next-gen Threadripper and Ryzen 3xxx series CPUs. It also means that AMD found the semiconductor manufacturing Holy Grail, as it can keep costs way down by producing small area (high yield) 7nm dies, and connect them via the 14nm-built infinity fabric. It will essentially punch out multiple CPU SKUs from a single package setup (altough, this is arguably overkill for desktop Zen 2).

Ako ne pregaze Intel u server marketu iduće godine, ne znam kad će.
Sklopili deal s Amazonom.
https://www.barrons.com/articles/amd...ces-1541528041

Koliko znam, Azure ih je već otprije koristio.
Bit će zanimljivo

HP, Dell (VMware), Cray, Oracle, IBM, Baidu, Microsoft (Azure), Amazon (AWS), Tencent, Google, Facebook - mislim da su pokrili sve veće igrače.

Intel muči to kaj single i dual-socket EPYC mašine nude jako lijepi omjer uloženog i dobivenog.

Isus AdoredTV je i najavio ovakav dizajn od 9 čipova tj. 8 sa jezgrama na 7nm + IO/ostalo na jednom velikom od 14/12nm. Ludnica.

Taj veći čip će im vjerojatno praviti GloFo, tako da rješe 2 muhe jednim udarcem
Nemoš vjerovat kako im se poklopilo, jer je zen2 vjerojatno tako zamišljen od starta sa Jim Kellerom.

Combining this breakthrough design methodology with the benefits of TSMC’s leading-edge 7nm process technology, “Zen 2” delivers significant performance, power consumption and density generational improvements that can help reduce datacenter operating costs, carbon footprint and cooling requirements. Other key generational advances over the award-winning “Zen” core include:

- An improved execution pipeline, feeding its compute engines more efficiently.

- Front-end advances – improved branch predictor, better instruction pre-fetching, re-optimized instruction cache and larger op cache.

- Floating point enhancements – doubled floating point width to 256-bit and load/store bandwidth, increased dispatch/retire bandwidth and maintained high throughput for all modes.

- Advanced security features – Hardware-enhanced Spectre mitigations, taking software migration and hardening it into the design, and increased flexibility of memory encryption.

Multiple 7nm-based AMD products are now in development, including next-generation AMD EPYC CPUs and AMD Radeon Instinct GPUs, both of which AMD detailed and demonstrated at the event. Additionally, the company shared that its follow-on 7nm+-based “Zen 3” and “Zen 4” x86 core architectures are on-track.

Meću i ne vade... baš fino
Iako me najviše zanima Ryzen desktop CPU, malo manje Epyc ali dobro je. 1 CCX sa 8/16 da bude u destopu je majka.

Samo pred 2 godine se ovdje pisalo o bankrotu AMDa i o tome kako je Agrokor veća firma od AMDa 2 godine kasnije, lntel se oznojava...

Imam osećaj da će mnogim zagovarateljima singl-tred performansi one odjednom postati nebitne, na isti način kako je i zagrijavanje/potrošnja nestalo sa usana istih.

What a time to be alive

Pazi(te) razliku između Rome i Naples EPYC modela. Dva ova mala 7nm 8C/16T Zen 2 čipa komotno (uz IO kontroler) stanu (primjera radi) na AM4 pakiranje. Zapravo, AMD sad može kombinirati kaj god ih volja, neovisno o socketu.

[Manuel Calavera]

Definitvno mogu sa iznimnom lakoćom izbaciti 16 core na AM4, tu odavno nema više dileme. Samo je pitanje dali žele tj. dali im to treba. Iskreno mislim da to neće navući 95% mainstream publike, ali bi moglo nekakvu semi-pro ekipu kojoj ne treba gro pci-e lejnsa, a ovih 95% će isključivo zanimati IPC i clock napredak, te i efikasnost.

Što se tiče ryzena 3xxx i Navija očito se onda čeka taj 09.01.2019 i CES za predstavljanje/najavu

[The Exiled]

Većini sigurno ne treba, ali hej - ko zna kaj bude Intel spremil za kraj godine. Zlu ne trebalo nek je i dual-7nm 8C/16T@AM4 opcija spremna.

[Brko]

Forbes kaže da je Intel naručio pošiljku od 90.000 plavih A5 kuverti.
