Gráfica AMD Vega (Radeon Vega 56 & 64 & Frontier Edition)

para quem como eu está agarrado a uma R9 390 8GB e não vai mudar porque estes preços estão malucos, talvez este vídeo traga um sorriso...

Su also said that the first company's first 7nm FinFET chips will be shipping this year, out of the Taiwanese fabrication plants of TSMC, although AMD will continue to have a relationship with the silicon shapers at Global Foundries. Su said she was expecting the new chips to be shipping in volume this year.

Vega 12/20 Added To AMDGPU LLVM, Confirms New GCN Deep Learning Instructions For Vega 20

Hitting mainline LLVM and Clang compilers today were support for Vega 12 "GFX904" and Vega 20 "GFX906" graphics processors.

Not much is unfortunately confirmed for Vega 12 besides being that it's a new part, not any Intel Kabylake G part, and the LLVM patch does confirm it is indeed a discrete GPU. Among the speculation is that Vega 12 could be a lower-end Vega part for succeeding the Radeon RX 500 "Polaris" graphics cards.

Vega 20 meanwhile is a product AMD has teased and mentioned is a 7nm GPU with 32GB of HBM2 memory. The Vega 20 is aimed for machine learning / artificial intelligence workloads albeit not yet launched. So it's not too surprising these patches do confirm new deep learning GPU instructions being present for Vega 20. The deep learning intrinsics added are fdot2, sdot2, udot2, sdot4, udot4, sdot8, and udot8.

Esses resultados já andam aí há um dia ou dois, mas tendo em conta que a própria AMD diz que a Vega é uma Instinct, digaom que o interesse é puramente teórico.
 
Pelo que vi algures por aí não se deve fiar muito nestes testes, pois a Gpu apresenta um clock de 1000mhz e acho que foi anunciado um clock muito superior. E que a bios ainda estava longe de estar perfeita.
 
Certo, só partilhei porque ianda não tinha visto aqui. Estes resultados não significam basicamente nada, apenas que andam em testes com este novo chip. Obviamente que isto é muito preliminar e nem se sabe se os 1000mhz que ali aparecem estão a ser bem "lidos" pelo software.
 
Hmm... alguém andou a vasculhar o código dos drivers opensource, e alguém se esqueceu lá de umas migalhas

Vega 20 adds support for Zero Frame Buffer (which I dont know what it does), Emulation Mode, new Data Fabric.
However I wish the DKMS present in this branch would be mainstreamed, because we could use any Linux version or distro and load the Kernel Module without upgrading the distro or wait for a new release.
The code looks far from prime time, looks like a HW bring up driver.

On the Vega 12 side I saw
It has a new SMU MicroCode
It has 16 DPM levels compared to 8 of Vega 10
It has a simplified thermal management and no LED control unlike Vega 10
It still has fan rpm control, which might suggest it is also meant for desktop
Funny thing is getting rid of the complicated Fan and LED control which is inherited from Vega 10 took out so much of the PP code :lol2:

Interestingly
I found this line in vega12_processpptables.c
#define VEGA12_ENGINECLOCK_HARDMAX 198000
Engine Clock hard Limit is 198000/100 Mhz = 1.98 GHz
This value is used in the overdrive engineClock limit calculation. It is read via SMC for Vega 10 and others, probably it is temporary.

relativamente à Vega 12, o DPM e SMU está explicado neste artigo da anandtech

dá para ver o unboxing e pouco mais, está em alomão...

Ui 8+6 pinos :n1qshok:

Na pagina da powercoler referem que requer uma fonte de 650w isto tudo para uma gráfica assim para o mini... ou esta me a escapar algo?

edit:
andei a ver pesquisar e encontrei uma build com uma sf600 com esta gráfica
