Gráfica AMD Polaris (RX 590)

Radeon Technologies Group Demos HDR at CES

AMD is making to their GPUs is that they plan on implementing High Dynamic Range (HDR) support on their current and next generation AMD Radeon GPUs, allowing AMD Radeon GPUs to support higher than 10-bit displays Allowing AMD GPUs to support up to 32-bit colour, which has full 16.7 million colours compared to 1.07 million colours with 10-bit colour.

CES 2016: AMD Talks Polaris GPU and HDR Monitors

 
AMD have begun shipping Polaris GPUs from the foundries. Based on the information from Zauba, it seems to be two different Polaris chips/families, each with 2 different SKUs/GPUs. Total of 4 new Polaris GPUs. The one with the biggest value is the full Polaris while the other one is the same Polaris GPU but with some shaders/cores disabled.

A explicação está nesse link, comparação dos P/N, as Fury têm um P/N 102-C8xxx, a série 300 P/N 102-C7xxx
 
VB: Does the Polaris brand supplant the Radeon brand?

Koduri: It’s an architecture codename. It’ll still be Radeon something something on the box. But we didn’t have a consistent architecture name like our competitors do. It was hard, because for people, including yourselves and some of the press and enthusiasts—This family of chips has this architecture and a similar class of features. You can group them easily together.

VB: Is that with a generation coming in 2016?

Koduri: Yes. We have two versions of these FinFET GPUs. Both are extremely power efficient. This is Polaris 10 and that’s Polaris 11.

Polaris 10 is an engineering sample for the APU Raven Ridge and the dGPU R7 460X. <50W power comsuption
R7 460X : 4 Shader Engines with 4 CU/SE => 16 CU : 1024 SP + 64 TMU
Other declinaisons for APU with 3 and 2 CU/SE would be.
Other declinaisons for dGPU with 7 and 8 CU/SE would be like for R7 470 and 470X

Polaris 11 is an engineering sample for the dGPU R9 480X. <150W power comsuption
R9 480X : 6 Shader Engines with 8 CU/SE => 48 CU : 3072 SP + 192 TMU
Other declinaisons for dGPU typically with 7 CU/SE for R9 480, and more CU/SE (from 10 to 16) for 490 to Fury2 X.
Seems legit how about 14/16 nm FF can afford actually for low and mid size die.

De onde é que isto vem?
 
Mais uns rumores, depois de Koduri na entrevista à Venturebeat er afirmado a AMD ir lançar 2 GPU FinFet este ano, havia a questão de como se iria conseguir cobrir toda a gama da nova séria 400, porque nada indica que a AMD vá manter as Fiji (Fury) no mercado, tradicionalmente (e no mesmo processo de fabrico) a AMD lança nova high-end/flagship, com a anterior a descer para o mid-high; mas o Charlie (Semiaccurate) diz (no forum) que não haverá 2 mas sim 3 chips FinFET, admitindo que sejam efectivamente lançados apenas 2 este ano, entretanto alguém notou que no HWinfo, surgiram informações de no próximo update irem ser acrescentados suporte para 3 GPU AMD

  • Upcoming changes in the next release:
    • Fixed monitoring of total/NAND reads/writes for some SanDisk drives.
    • Extended NVMe S.M.A.R.T. status and fixed total writes amount.
    • Fixed reporting of sub-zero temperatures on NVIDIA GPUs.
    • Added support of Samsung SSD 950 Pro using the default Microsoft NVMe driver.
    • Added preliminary support of AMD Ellesmere, Baffin, Greenland.
    • Fixed GPU I2C access on AMD Tonga/Amethyst.
    • Added options to choose which type of values (current, mix, max, average) to show in tray, LG LCD and RTSS.
    • Enhanced sensor monitoring on ASUS Z170-PREMIUM.
 
Tinha conhecimento de ser 2 GPU FinFet mas agora 3 só for nova geração fury 2 com novo GPU desenhado. Pode ser 3 novos GPU para cobrir desde gama low até high. Já falei muito. AMD precisa novos GPU e CPU para conquistar novamente mercado e cota mas guerra continua.
Para muito brevemente podemos ter APU com hbm para novo socket de consolas.
 
Seria no mínimo interessante, resta saber se é marketing ou não. Mas a ser, entre Polaris e Zen, a AMD pode estar a tentar fortalecer-se bem nesta zona do mercado.
 
Para quem está fora do assunto e percebe pouco do assunto mas quer informar-se mais, esta geração polaris é só high end ou vai ser algo para todos os preços?

Sendo um pouco de off-topic mas penso que seja melhor ficar num só post a plantaforma zen é a resposta da amd aos skylake?

Em principio pelo que eles (para já) dão a entender é que será um upgrade geral a todas.

Por isso é de esperar que todas as polaris saiam desde o sector mais barato ao mais caro e com a arquitectura GCN 1.3 e 14nm
