AMD Radeon R7/R9 400

[Jorge-Vieira]

Curious what Polaris' rear connectors looks like? Check inside

AMD's Capsaicin event at GDC was quite the blast, if not for the reveal of their Radeon Pro Duo dual-GPU, VR-focused monster card, they also took time to show off just how potent Polaris 10 actually was. And someone was lucky enough to get a close-up of its behind. And it looks like any other GPU's derrière.

Looking closely, which is easy here, you can see that the connectors include three DisplayPort (presumably 1.3) one HDMI (likely 2.0) and a DVI-D port. And we get our first peek at the prototype PCB as well. Though it's only a prototype, and this could change. There it is. It is an engineering sample, so things could change in the future. The best part is the small form-factor it happens to be in. AMD is definitely committed to bringing more power to smaller form factors.

This is "Big Polaris", or Polaris 10, that's running the newest Hitman using DX12. It's stuffed in a Cooler Master Elite 110 case, meaning the board is minuscule to be able to fit into that case. The PCB is probably around the size of the R9 Nano and should consume less power than any Fiji based board to date.

@jotinha, com estas novas gráficas, (AMD e Nvidia) vamos ver certamente um boom na tendencia que ja eram os sistemas micro-atx

AMD's next-gen Polaris-based R9 490 should rock 8GB RAM, 256-bit bus

As we get closer to NVIDIA's GPU Technology Conference, it should come as no surprise that more leaks are arriving on AMD's next-gen Polaris architecture. This time, it's in the form of the Radeon R9 490 and R9 480 video cards.



According to the new leaks, AMD will slap 8GB of the new GDDR5 (and possibly GDDR5X) memory onto the R9 400 series cards, with a 256-bit memory bus. There'll also be 2304 fourth-generation GCN cores, which should be able to easily compete against the likes of NVIDIA's Pascal-based GeForce GTX 1070 and GTX 1080 cards (placeholder names, I really don't see NVIDIA calling them as the GTX 1000 series).

AMD's Polaris cards will be made on the 14nm FinFET process, but remember - these cards are the R9 490 and R9 480, not the R9 490X that should be a little beefier. The R9 490X could be different, where it will feature the faster GDDR5X, while the R9 490 might retain the GDDR5 standard.

AMD Polaris 10 and 11 are Ellesmere and Baffin – Polaris 10 Specification Spotted

With just about 2 months to launch, it is inevitable that more details about Polaris are going to leak out. According to a patch submitted by AMD, it appears that Polaris 10 and 11 are the same chips previously leaked as Ellesmere and Baffin respectively. Furthermore, it appears that Ellesmere will be an R9 390/390X configuration replacement but offer Fury X like performance.
According to the patch, Polaris 10, the top end Polaris chip is codenamed Ellesmere while Baffin is Polaris 11. This collaborates previously released information that Ellesmere, Baffin and Greenland would be launching soon. While Baffin has been spotted shipping, Ellesmere has not, suggesting it is either a bigger more complex die or the higher end product AMD wants to keep under wraps.

Finally, we are getting some more specifications for Polaris 10. According to benchmarks spotted online, one Ellesmere configuration will be 2304 GCN cores in 32CUs running at 800-1000mhz. The chip will also have a 256bit memory bus and 8GB of VRAM running at 1500Mhz (7500Mhz effective). This places the card as a solid replacement for the 390/390X segment with a 2560 core unit being the top model. The reduced memory bus width is offset by AMD’s lossless texture compression and increased GDDR5 clocks.
Given the gains from 14nm and the new Polaris GCN architecture, it wouldn’t be unexpected for a 2560 core unit to beat Fury X as shown in the Hitman demo. This means AMD has managed to bump GCN performance by about 30%, the biggest from them since GCN was originally launched. With Pascal not expected to give much of a boost, AMD may finally seize the performance/efficiency crown from Nvidia.

8gb neste momento com a RV aí à porta, era o indicado.

Boas!
Não deixa de ser bem menos do que esperava...

HBM 2.0 com 8GB é que era... GDDR5x... prontos... meio caminho andado...

Cumprimentos,

Boa tarde,

Com o USB-C já cá fora, capaz de debitar 100W e ter incorporado o DisplayPort... porque raio não saem as gráficas com entradas USB-C? E os monitores também. Acho que 100W chegaria bem para abastecer um monitor (digo eu). E sendo que o cabo também pode ter DisplayPort fica a parte do áudio e da imagem tratada também. Com um cabo resolvia-se três coisas diferentes. Nem se andava mais com cabo de alimentação próprio para o monitor.

Cumprimentos.

O monitor vai ter sempre cabo de energia porque quem não tem gráfica nova ou usa um IGP ou APU também vai comprar monitores...

Boa tarde,

A motherboard se tiver portas USB-C elas podem alimentar o monitor... não? Isto em caso de se usar o iGPU ou uma APU.

Cumprimentos.

[dblaster]

E essa alimentação eléctrica do monitor é proveniente de onde?
Se for da gráfica por exemplo tem que ter mais conectores de 8pinos lá ligados.

[Zavtekirou]

Boa noite,

Com possíveis melhoramentos de consumos das gráficas, quem sabe isso não seja preciso... e possivelmente cada vez os monitores gastarão menos energia também...

Cumprimentos.

Resolve-se o problema facilmente com a seguinte solução: saida directa usb-c da fonte

[SleepyFilipy]

Mas aí não estaria a passar dados pelo cabo, seria somente alimentação, para isso mais vale deixar como está

Não se pode ter tudo...mas nesse caso, até se podia

[Zavtekirou]

Boa noite,

Eu quero é eliminar o máximo de cabos possíveis, através da fusão ou eliminação dos cabos. Para mim seria perfeito ter só um cabo para imagem, som e energia. Penso que o usb c possa ser a solução... Mas posso estar enganado... Os monitores externos da Apple não funcionam assim? Com um cabo thunderbolt que transporta imagem, som e energia? Ou há cabo de alimentação na mesma para o monitor externo?

Cumprimentos.

[Enzo]

Por acaso nunca reparei. Mas numa era em que tanta coisa é wireless, parece que cada vez vejo mais cabos
