a placa tem power para isso?...
como nao tinha o cPU é que aguentava com isso..
Sim o GPU da placa é que faz o decoding.

Chega ja esta semana ou para a próxima.Só mais 1 pergunta... essa 2900PRO chega quando? em Novembro/Dezembro?
http://my.ocworkbench.com/bbs/showthread.php? threadid=67462According to various sources, the AMD RV670 series will have two new members, the RV670 XT and RV670 Pro. They are also known as Gladiator and Revival. These two models might finally be known as Radeon HD 2950 XT and Radeon HD 2950 Pro.
In terms of Specs, the Gladiator core runs at 825MHz, 512MB GDDR4 at 1.2GHz. Revival core runs at 750MHz with 256M/512M GDDR3 clock at 900MHz. Both GPU are 55nm manufacturing processed and they both have 320 Stream processors and memory width at 256 bits. Supports DX10.1, SM4.1, PCIe 2.0, UVD and new generation CrossFire (tri / quad fire?)
RV670 XT graphics cards will be manufactured by AMD while RV670 Pro will be manufactured by graphics card makers. These two new products are expected to arrive by end of this year or early next year.
A parte mais estranha é que diz que a HD 2950 XT vai ser fabricada nas fábricas da AMD e a HD 2950 PRO nas TSMC.
Então a 2950XT vai ter bus a 256bit, quando a 2900XT já tem bus a 512?
Mesmo tendo a memória a 2.4Ghz, está longe de atingir os 105GB/s da 2900XT.
Ou a 2950XT é mesmo um dual-core com um crossfire interno de 2*256bit, ou então isso cheira-me muito a esturro.
Inquirer disse:AMD silently launches R630 GPU - the HD2900Pro
Lower-spec R600 model available today from GeCube
WITH NO REVIEWS in place, ATI Radeon HD 2900 Pro boards appeared on the market. GeCube was the manufacturer to break the deadlock and send boards through the channel, and the 2900 Pro is available in Europe today.
On my favourite price search site, Geizhals.at, several retailers and e-tailers list GeCube GC-HD2900PRO-VIE3, a board based on R630 chip with full 320 superscalar shader units and 512MB of GDDR3 goes for 225-250 Euro, or probably around 225-250 Dollars (sadly for us Europeans, Americans have 7-10% VAT, while we have 15+ and far stronger currency… feel like everything is free here in Frisco… two 8800Ultra boards cost as one 8800Ultra in Croatia etc…).
As far as we can tell, memory interface on the board is now 256-bit, half of what R600 has. This board actually already exists on the marked as FireGL V7600, and we know that R600 chip with 256-bit memory controller unlinked is called ATI R630.
Clock has been decreased to 600 MHz for the GPU, but memory was decreased by only 26 MHz (or 52 MTransfers/sec) to exactly 800 MHz (1.6 GT/s). With this new spec, this board spots 51.2 GB/s of on-board bandwidth. We don't know the performance characteristics right now, but if you just got this board, we'd be more than glad to see the scores. This low key launch probably means there is no sampling for reviews, but the price is somewhat right.
Now, the only question remains here: if AMD is so silent about new SKUs from the R600 family, does this mean RV670 and R680 will turn the pages or is company preparing all they can for the R700 generation of products? Only time will tell, but somehow my hunch is that something big is cooking in AMD's kitchen...
http://www.techzonept.com/showpost.php?p=2016273&postcount=79tanta largura e banda começa a ser markting... ou nao??
Axo que vai haver 2 duas versões. Umas a 512bits mais caras e outras a 256bits mais baratas.
As versoes 512bits nao vao durar muito tempo no mercado. Vai ser uma daquelas reliquias que esgota em 24h.
São simples HD 2900 XT com menos clocks por metade do preço.
Isto tb deixa pensar o quanto os gaijos nao ganham por cada HD 2900 XT vendida. Se a Pro custa 225 e a XT 360 euros, ganham pelo menos 135 euros por cada XT. Isto sem contar que as HD 2900 PRO tb têm que ter lucro, logo devem ganhar mais de 150 euros de lucro por cada XT. Xulos
http://www.beyond3d.com/content/interviews/39/3Eric Demers disse:All of our designs have had redundancy (pipeline and shader) with fuse support since R420. Basically, if a quad pipeline was detected to be bad, any one of them, or more than 1, could be turned off by fuse. This has lead to many of our mainstream parts, in the past. The same thing existed on R5xx parts, with the R580 and R530 capable of also scaling the amount of SIMDs per quad pipe as well, under electronic fuse control. The R6xx has expanded beyond this, with quad pipes, simds and various other aspects controlled by both redundancy and the ability to turn off subsets. The R600, for example, has redundant shader scalar cores, that replace broken ones internally, to maintain the same performance but increase yield.
As well, we can disable SIMDs or quad pipes internally, to recover parts that redundancy cannot fix. Overall, this strategy has allowed us to have a high end solution and then also capture back parts for lower end designs (the funny thing is that as yields improve, over time, this solution actually doesn’t do as well, as it forces the average sell price of the die down to the lower end part; just a note). At this time, ATI Radeon HD 2900 XT is a full featured part and no other parts have been announced
