ATI RV770 | Radeon HD 4800 séries

[ObscureAngel]

Ya e como foi mostrado nas imagens atras que a ati 4870CF fazia aquele framerate eu acho que é fake!

a nao ser que tenha saido novas drivers milagrosas para a ati

Cumps..

 

[Passarinhuu]

TOu a estranhar muito mas mesmo muito essas imagens!

JA tive a ver as reviews e nao me lembro de ver framerates tao altos a very high!

No entanto se for mesmo verdade como ai tá!

Devemos estar mesmo perto de correr o crysis finalmente maxed out! com filtros

Há mesmo qualquer coisa de errado com esses resultados. Compara single HD4870 com CF, o resultado até é mais alto a 1280x1024 com single, e nas outras resoluções o CF de HD4870 tem mais fps a 1920 do que a 1680.... de certeza que isso é problemas de drivers

por esse gráfico só sei que a GX2 continua no topo

Se olhares po grafico os resultados nao correspondem a tabela, há qq coisa de errado com isso. Ca para mim trocaram os valores entre a GX2 e a GTX280

Acho q aquilo é o crysis com o Very High em DX9 com a tal modificaçao dos .inf...por isso é q ele diz q é custom Very High.
Crysis - custom Very High config - no AA

Por isso é q lhe dá frame rates tao boas.

Chiphell seems to have the pcb shots of the R700 now. Black pcb and all...

Chiphell

No surprise there as we see the smaller PCIE 2.0 PLX chip. Also of note is that the board is definitely much shorter than the R680 it looks like. RAM is on both sides as well.

Then there was this CNET article today that mentions the new propietary interconnect.

CNET Article

For ATI, the execution of this chip-ganging strategy is the key. And this is where ATI appears to have been successful. "The inter-processor communications. Getting that to work has been the trick. This is what ATI has done. They've come up with this stellar way of doing inter-processor communications so they can in fact get the scaling," according to Peddie.

AMD-ATI's upcoming R700 (rumored to be called the 4870 X2) two-chip graphics board will be the ultimate test of this strategy.

"It's a new proprietary inter-processor communication technology. If they put these two chips on one board and it does scale properly, then they have pulled off a coup," he said.

"When you gang up graphics chips (using the traditional Scalable Link Interface or CrossFire technologies) they roll off pretty fast. ("Roll off" implies that performance doesn't scale up well.) "So when you put two boards in, you don't get twice the performance but you (only) get one and a half. You put four boards in and you (only) get about 1.7, 1.8. What ATI is saying is that with two chips using (their) proprietary inter-bus, they will get 1.8 (the performance) with two chips. If that's true, you can expect to see four of them giving you something around 2.5."

Getting 2.5 times the performance from four boards would be a masterstroke for ATI.

The previous ATI dual-chip solution was very different, Peddie said. "The HD 3870 X2 was not a proprietary bus but a CrossFire connection. The CrossFire connection and the SLI connection are at the very, very end of the pipeline. Not the most efficient place to do an inter-processor communication. That's one of the reasons ATI has abandoned it."

So basically the card will not be CF on a board but will be a new interconnect between the GPU's. Also, it seems to suggest that the CrossFire connection was redone in the RV770 or at least for R700 since Peddie suggests that the CF connection is no longer at the very very end of the pipeline. Maybe that's why recent CF results of the 4800's show incredible scaling when it works?

Anyways, with the plethora of information of R700 that was just released it seems like ATI is pushing hard to get these cards out fast.

AMD’s Share on Graphics Card Market Set to Increase – Graphics Cards Makers.
ATI Radeon to Command Larger Part of the Market

Graphics cards makers expect ATI, graphics product group of Advanced Micro Devices, to gain market share in the third quarter as a result of ATI Radeon HD 4800-series graphics processors launch. But while there is overall optimism regarding market performance of ATI’s novelties, it is unlikely that the roll-out that occurred in the end of Q3 will dramatically impact market share.

For several quarters not ATI/AMD’s share on the market of desktop discrete graphics adapters was 35%, whereas Nvidia outsold the rival 2:1 and commanded 65% of the market, according to Jon Peddie Research. Taiwan-based graphics cards makers, which remained anonymous, said to reporters from DigiTimes web-site that they expected AMD to increase its share to 40% of the market in Q3 2008, a rather optimistic prediction.

The expectations may overestimate the impact of the ATI Radeon HD 4800-series release since it occurred in the end of the quarter and could hardly reach ATI’s partners in massive quantities. Nevertheless, if forthcoming launch of ATI Radeon HD lineup decreased the pace of sales of Nvidia GeForce lineup, AMD could well gain market share.

AMD’s graphics product group did not comment on the news-story.

bem, se essa performance chegar mesmo vai haver muita gente na nvidia e fazer horas extra sem vencimento senão a ati papa-lhes o mercado

já agora aquele pcb fica mesmo bem com uma dfi ut ou dk

 

[H3llsinG]

Parece que a ATi agora vestiu a pele do Lobo, e a Nvidia de Cordeirinho

O resultado da ATI ter andado a fumar mais coisas halucinogénicas com 6 meses de atraso.

Èpa sem palavras mesmo!! Brutais as Imagens

Acho mais brutal o numero que está ao canto do que as imagens em si

Exacto... é mesmo uma destas que vou levar para casa no fim do mês que vem!! Finalmente um placa, sem ser super cara, que "mama" qualquer jogo na boa!

As 2 coisas

Fogo é de ficar nas nuvens com essas graficas ATI! Mesmo a Calhar
Excelente resultado em jogo numa resoluçao 1600x1050!

cumps

Crossfire X in action HD4870 + HD4850 :


Ok Crossfire is up and running! I'm going to to 3d06 and Vantage once again, same oc'd settings on my system, stock clocks on the cards.

HD4870 + HD4850 Crossfire X stock clocks. Q6600 @ 3.6ghz, 400FSB, 1200mhz RAM










Crysis in Crossfire. All the same system settings as before...

Here's the last bench of the night with the 4870 OC'd to 790/2000 (4000 effective)

impressionante o poder da 4870 CF.

COD4 a 200-400 fps com AA e AF para dar e vender.

crysis very high a 50-100 fps.

que brutalidade de gráficas e ao mesmo preço de 1 GTX280.

E a 4870 X2 se prometer eliminar os problemas de sincronismo e com nova PLX PCI-e 2.0, bem vai ser uma "razia"

2x R700 = ~5 teraflops

E penso que poderá ser possível montar uma maquina para GPGPU, com 4 meninas destas, 8 gpus = 6400 stream processors = 10000 gigaflops

 

[jopr]

Crysis Very High em DX10 a ~30fps. Nas imagens in game onde haviam os 50fps para cima era Very High em DX9.

 

[DMH]

Sim porque em very high DX10 há quebras de 42% em relação ao very-high DX9

AMD expected to grab 40% discrete graphics card market share in 3Q08

With AMD's ATI Radeon HD 4800-series graphics cards successfully cutting into the US$200-300 mainstream market forcing Nvidia to cut the price of its previous generation GeForce 9800 GTX down to US$199, sources at graphics card makers see AMD's discrete graphics card market share as having a chance to increase to 40% in the third quarter this year from around 30% at the beginning of 2008.
Since Nvidia's GeForce 9800 GTX does not provide advantages in power consumption or performance over the same priced Radeon HD 4850, graphics card makers are more optimistic over AMD's upcoming performance.

Este PCB preto é que é para não distinguirmos com as Nvidia, a X2 é apenas 15% mais rápida que a GTX280?Esperava mais

 

[apenas_nuno]

é mais barata...

e os drivers vão trazendo sempre melhorias

Amigos, podem me tirar um dubida, eu tenho um LCPOWER 550W com 40A mas só tem uma fixa de de 6 pinos, dá para ter uma hd4870 nesta fonte existe algum adaptador, obrigado e bons upgrades

Existe um adaptador que liga a uma das fichas normais e depois tem na outra ponta a tal de 6 pinos. Por acaso esse mesmo cabo já vem nalgumas placas gráficas, provavelmente virá na HD4870 também.

Já agora aproveito o post, compensa a diferença de 154€ (HD4850 512 GDDR3) para 279€ (HD4870 512 GDDR5)?
Ainda são 125€, quase que dá para outra 4850.
