Despite what ATI told us at our Avivo briefing last month (although ATI insists it was a miscommunication), H.264 decode acceleration is not launching alongside the R5xx GPUs. ATI is committed to bringing both H.264 decode acceleration and transcode assist by the end of the year, but for now, we have no way of testing those features.

The subjective numbers add up to pretty much summarize our experience with ATI's Avivo at this point. While neither ATI nor NVIDIA produced a perfect solution, at this point Avivo is definitely a step behind NVIDIA's PureVideo in terms of de-interlacing quality.

Something I find less charming regarding all cooling solutions on the entire range of X1000 cards is that the fans are rather noisy. Not terrible but definitely clearly audible during gameplay or when the core temperature rises beyond a certain threshold.

A X1800XT não está nada mal para uma grafica com apenas 16 pixel pipelines. A velocidade que atinge consegue fazer com que tenho um fill rate de texels quase tão grande como a 7800GTX e a nivel dos ROPs arrasa com a 7800GTX. E os 48Gb d memory bandwith tambem ajudam bastante.
Acho é estranho que tenha tantos transistors para apenas 16 pipes.
No geral acho q a vitoria, na luta entre a 7800GTX e X1800XT pertence á ATI, mas por pouca margem.

P.S. : Gostava de ver testes com as novas FW 81.82

Há reviews com os 81.xx, que de certa maneira "salvaram" a nvidia. o r520 não foi a desgraça que alguns apregoavam e esperavam, mas tb não consegui arrasar a gtx que alguns esperavam.

No geral esta tudo muito confuso com os 1000 diferentes drivers da nvidia usados, e por simplesmente dizer 4AA e 16AF não significar que os diferentes produtos estão com settings equivalentes.

Fico com a ideia que é mais rápida, especialmente no jogos mais recentes, e alem disso conseguem ter um IQ melhor, adaptative AA, HQ AF, e AA no HDR. Continua a perder no opengl, mas já não é o massacre que era há alguns tempos atras, e no doom3 parece bastante equilibrado.

As xt de 512mb so vão estar a venda no principio de novembro, e com um preço de 650euros, muito longe dos 550$ "sugeridos".
 
Conclusoes:

The basic architecture, clocks and memory size of the Radeon X1800 XT make it undoubtedly the fastest overall graphics accelerator on the planet, ATI regaining the crown they've not worn since GeForce 7800 GTX and G70 blew us all away back at the end of June. The performance crown, while not as important as it used to be, is a fine fitting one to wear proudly and X1800 XT does that straight out of the gate. The general rule is that if it's D3D9 and you're not CPU limited, it'll likely blow everything else away at the time of writing.

So what have we learned from the launch of the X1800XT? Well first off we can see that ATI have made some huge improvements over the X850XT. There are as expected increases across the board however some of the increases such as those seen in Battlefield 2 are quite astounding.

Looking next at the new features the X1800XT brings to the table there are two which are immediately beneficial to everyone. The first is adaptive anti aliasing, as you can see from our image quality screenshots there are some real benefits to IQ when you apply the new technique. The fact that these IQ benefits are not accompanied by huge performance hits is great. Also immediately beneficial is the ability to use AA with HDR. As mentioned previously there isnt another product on the market that allows this so ATI may well be on to a real winner here. That is of course if Nvidia don’t manage to release a comparative feature before many games take advantage of HDR.

In summary, the X1800XT does exactly what it should. In most applications it outperforms every other single card solution on the market whilst at the same time bringing some excellent must have features to the graphics card world. When you consider all of this comes backed by ATI's excellent software suite which provided us with complete stability throughout our testing period (and for many months previous) its hard not to recommend the X1800XT to anyone wishing for the fastest 3D performance.

From a pure graphics technology standpoint, the Radeon X1000 series of graphics processors doesn't break new ground with bold innovations, but it does give ATI nearly every feature that the GeForce 7 series GPUs have had over the Radeon X800s. Not only that, but ATI has added a number of worthwhile capabilities, including multisampled antialiasing with high-dynamic-range color modes, "free" tone mapping via the Avivo display engine, and much finer-grained batch sizes for dynamic flow control in Shader Model 3.0. ATI has also caught up with NVIDIA on the internal chip architecture front by decoupling the computational units responsible for the various stages of the graphics pipeline from one another, allowing more flexibility for the development adventurous variations on the core GPU architecture, like the RV530

At the very high end of the market, the Radeon X1800 XT is indeed a worthy competitor for the GeForce 7800 GTX. In Direct3D games, the X1800 XT is usually faster than the 7800 GTX. Unfortunately, ATI's weak showing in OpenGL games keep the X1800 XT from capturing the undisputed heavyweight title. I also have a few concerns about the likely extent of the Radeon X1800 XT's availability in the market, given its relatively high GPU clock speeds. We will have to wait and see about that.

There's so much new stuff in these cards that it's almost hard to wrap your head around. ATI has caught up to Nvidia with full support for Shader Model 3.0, though ATI claims it does this better and suffers less from games with long complex shaders and lots of dynamic branching. We'll have to wait for more advanced games to test these claims. The new memory controller, shader thread dispatch unit, and improvements to compression and cache are really promising. ATI has stepped up its video and display output game with this first Avivo-branded part. We'll dig into these features in more detail in a separate article, but our simple subjective tests left us with a great opinion of it. We also like the fact that ATI has a full top-to-bottom card lineup, even if there is quite a gap from $249 to $449. Unfortunately, not all the cards are shipping yet. We've chosen to focus on the two top-tier X1800 cards here.

3dmark01 numa placa destas?

Quanto às reviews, a X1800 parece-me uma boa placa. No geral é mais rapida que a 7800GTX.
Em termos de features, nada de muito novo. A opção do AF é uma boa surpresa. AA com HDR também.
O Adaptive AA é igual ao transparency AA da nVidia.

Já a X1600 é a mais estranha da familia. 12 pipes, mas só 4 texture units. Fill rate quase igual à X1300, mas com o ring bus, + vertex shaders, etc.
Pelo menos a X1600 XT não parece dar grande luta à 6800.
 
A X1600 por agora nao vai ser lançada.
Parece que querem prolongar as versoes X800GT/GTO/GTO2 por mais algum tempo para dar saida as chips R480 e encaixalos nas margens de preço da X1600 e ao mesmo tempo têm controlado essa cota de mercado com performance superior.

Eu penso que será assim:

Top Ultra-End:
X1800XT
High-end:
7800GTX/GT
X1800XL
(X1800pro??)
Mid-end:
X800GT/GTO/GTO2
6800ultra/GT dependendo do preço
Low-End:
X1300

Esse top Ultra-End é para rir não...

Já agora esse mid-end é discutivel, e no lowend a Nvidia tb não tem nada...ai ai ai :rolleyes:
 
Parece uma placa porreira a X1800
É genericamente mais rápida que a GTX mas não oferece assim nada de especial em relação a esta (um bocado como a GTX em relação à 6800U)
A ATI ganhou o direito de dizer que tem a placa mais rápida do mercado
Agora a guerra segue para os preços e disponibilidade
Tb vai ser interessante ver se surge a G80 ou algum tipo de resposta diferente
 
Top-Ultra-high-GT-Mega Tuning-End :D :
SLI/Crossfire 7800GTX/GT e X1800XT/XL
Top Ultra-End:
X1800XT
High-end:
7800GTX/GT
X1800XL
(X1800pro??)
Mid-end:
X800GT (escolha eem detrimento da 6600GT)
X800GTO (escolha em detrimento da 6800)
X800GTO2 e 6800ultra/GT (nos 250/300 euros)
Low-End:
X1300 Nao dá hipotese.

É uma maneira simpatica de dizer que a gtx é uma excelente placa, mas agora vai passar a existir uma melhor.

thread interessante no anando sobre IQ, resta saber se os novos drivers para o black and white resolvem isto.

Pensas que só há bugs nos drivers deles ?
Bugs da X1800...:

Anyway, during our tests we stumbled into a bug here and there. Riddick performance was way beyond what it's supposed to be, also at one point Doom 3 rendered a black screen once, a reset fixed this though. And we did see abnormal performance for the X1600 XT with Doom 3 and 4xAA and 8xAF enabled. This test had to be done with the only beta drivers available.

The Radeon X1800 XL is impressive, but not as impressive as the GeForce 7800 GT is. Often the score is close to the competitors card yet for some reason at several tests falls behind in performance quickly up-to a level where it was close to the Radeon X850 XT series of cards. Now don't get me wrong, that's still really lovely performance. Yet you can pick up an x850 XT for under 350 USD these days. It might be driver related though. The drivers we had available were beta and what I understand from the driver team not at all optimized just yet for the new cards.

Basicamente temos finalmente resultados reais de algo já bastante atrasado.
É ligeiramente mais rapida a nivel de DX9 que a GTX, mas também não deverá ser por muito mais tempo...


A ATI conseguiu recuperar o titulo de Single Graphic Card System mais rapido do mercado. :)

O problema prende-se pelo facto de por quanto tempo mais até a Nvidia decidir atacar a sério (porque eles podem...), a disponibilidade destas X1800 e os preços (pq esperem agora pela descida das 7800GT/GTX).


No Fundo, fico feliz por este lançamento (finalmente) porque todos nós ganhamos.
