AMD's next compute GPU could have two dies and 128 GB of memory

Aldebaran, the computer part, has appeared a few times in Linux patch notes. Its two-die design was half-implied in February and confirmed last month: "on Aldebaran, only primary die fetches valid power data. Show power/energy values as 0 on secondary die", one note reads. It’s the first AMD Accelerator/GPU to leverage an MCM (multi-chip module) design, a technique that’s been plastered on patents for years but has only just begun to materialize. Using multiple chips/dies connected closely allows for more scalability than traditional monolithic designs, but also reduces the per-compute unit performance of a card, particularly in poorly parallelized workloads. nVidia is expected to challenge Aldebaran with their own MCM designs based on the Hopper architecture next year. Intel, meanwhile, is on the verge of releasing the Ponte Vecchio accelerator based on the Xe HPC architecture and an early MCM implementation. Like Ponte Vecchio, Aldebaran leverages MCM to expand memory capacity, patch notes imply. A note from last week describes Aldebaran as having two dies, four UMCs per die, and eight channels connected to 2 GB of HBM per UMC or 128GB, in total. The patch notes also mention support for a "new HBM2 memory type," presumably HBM2e. If AMD is using SK Hynix’s new HBM2e memory modules with 3.6 Gbps of bandwidth and a 4096-bit bus on each die, then Aldebaran could have 3.6 TB/s of memory bandwidth. AMD CEO Dr Lisa Su has already said that the CDNA 2 architecture, meaning Aldebaran, is slated for release later this year. Presumably, it will release as the MI200 Accelerator.

Next-gen AMD Radeon RDNA 3 flagship to feature 15,360 stream processors?

AMD's next generation RDNA3 graphics architecture generation could see a near-quadrupling in raw SIMD muscle over the current RDNA2, according to a spectacular rumor. Apparently, the company will deploy as many as 15,360 stream processors (quadruple that of a Radeon RX 6800), and spread across 60 WGPs (Workgroup Processors), and do away with the compute unit. This is possibly because the RDNA 3 compute unit won't be as independent as the ones on the original RDNA or even RDNA 2, which begins to see groups of two CUs share common resources. Another set of rumors suggest that AMD won't play nVidia's game of designing GPUs with wide memory bus widths, and instead build on its Infinity Cache technology, by increasing the on-die cache size and bandwidth, while retaining "affordable" discrete memory bus widths, such as 256-bit. As for the chip itself, it's rumored that the top RDNA 3 part, the so-called "Navi 31," could feature a multi-chip module design (at least two logic dies), each with 30 WGPs. Each of the two is expected to be built on a next-gen silicon fabrication node that's either TSMC N5 (5nm), or a special 6nm node TSMC is designing for AMD. Much like the next-generation "Lovelace" architecture by nVidia, AMD's RDNA 3 could see the light of the day only in 2022.

Hoće li to efektivno značiti jeftinije RDNA3 od prethodnika?

[The Exiled]

Neće, jer nVidia i AMD zadnjih nekoliko godina imaju jebenu potvrdu da su krajnji kupci spremni platiti koliko god treba, neovisno o namjeni i(li) potrebi.

AMD ionako već ima spremnu MCM CDNA 2 MI200 karticu, tako da će RDNA 3 MCM modeli iskoristiti iste chiplet temelje, a cijene će sigurno biti paprene.

Prošla su vremena 200$ do 250$ kartica poput HD 4870 ili HD 5850.

Prošla su vremena 200$ do 250$ kartica poput HD 4870 ili HD 5850.

problem je i u tome što grafe niže vrijednosti daleko slabije profitiraju po pitanju perfomansi s novim generacijama

3080, 3070 imale su popriličan napredak u odnosu na prethodnice 2080 i 2070
jeftinija 3060 je puno manji napredak u perfomansama u odnosu na 2060

a nije nit amd ništa bolji, 6700xt je 20-30 posto jača od prethodne 5700xt, a
jeftina 6600xt će imati puno manji napredak, čak su i broj jezgri smanjili u odnosu na 5600xt, što sa 6700xt nisu radili jer ima isti broj jezgri kao i prethodna 5700xt

dakle namjerno se ide na to da jeftinije grafe srežu i da ispadnu manje isplative za upgrejd

[The Exiled]

Da, nažalost skužili su da im to uredno prolazi, a i Škot se u nekolicini svojih osvrta bavil tim da nVidia i Radeon s godinama sve više dižu cijene uz sve manji napredak u performansama u odnosu na prijašnju generaciju.

Jebiga, dokle god prolazi, nemaju razloga za promjene, a vidimo iz svakodnevnih primjera da su ljudi uistinu spremni platiti svaku cijenu. Dok nekome ne pukne film, obje firme dalje nastavljaju istim putem.

Sami smo si krivi...a oni nisu blesavi da gledaju kako skalperi i trgovci zarađuju ko blesavi. Dignu cijenu max tak da njima ostane manje manevarskog prostora.

Pa da, jasno je da npr. jedna RX 6700 XT nema kaj koštati više od 2.500 kn do 3.000 kn, jer je to rang u koji po pitanju performansi spada, ali možemo se slikati kad se prodaju za duplo više bez problema.

AMD confirms initial shipment of Instinct MI200 “Aldebaran” accelerator, its first MCM GPU

AMD said this week that it had started initial shipments of its next-generation Instinct compute GPUs based on the CDNA 2 architecture. These aren't the sort of GPU you'd find in the best graphics cards. Instead, the new Instinct MI200 compute accelerator carries 128GB of HBM2e memory and is designed for supercomputers and other high-performance computing applications, such as AI or ML. AMD's Instinct MI200 'Aldebaran' compute GPU will power the world's first exascale-class Frontier supercomputer, due to be delivered in late 2021 (as well as some smaller machines), so it's about time for AMD to start production of the accelerator. AMD has not yet disclosed any architectural peculiarities about CDNA 2, so the only two things we know about the Instinct MI200 for sure is that it features two dies connected with each other using AMD's Infinity Fabric, and it carries 128GB of HBM2e memory that connects to the dies using two 4096-bit interfaces.
