As coisas parecem não querer se resolver para os lados do Canadá...
Problemas com o R520, desde problemas de leakage a chips com só 16 dos 32 pipes a funcionar, o novo R520 já tem 8 meses de atraso e ainda nem tem o design pronto.
The information on the R520 suggests that there are some extreme yield problems with the current design. Not only are there few working dice per wafer, but a large number of those dice only have 16 pixel units working, and others are lucky to get 24 working. The information I received suggested that the R520 was in fact designed with 32 pixel units (each with multiple ALU’s), but due to the issues that the chip is facing, very few of them so far are fully functioning. There are of course fully functioning parts that have been shown behind closed doors, and apparently Abit showed off a working card at AConn that scored some impressive 3D Marks.
No campo do Crossfire:
the CrossFire solution requires the use of a “Master” card, or a “CrossFire Edition”. Currently there appears to be two cards that will be offered in CrossFire form. The X850 XT and the X800 (256 MB and 128 MB versions). While consumers will have to choose between those two cards to enable MVP, they can utilize a wide variety of X800 and X850 cards to work with the CrossFire Edition card.
While the technology looks fine (though a bit more cobbled together as compared to NVIDIA’s SLI), I am a bit leery of the claims that ATI is making about their product. It is well known that many older titles do not work as well on NVIDIA’s SLI, and the current driver from NVIDIA only enables automatic SLI profiles for around 70 applications. ATI is claiming that they won’t have that problem, and that nearly every game out there can take advantage of MVP. That is a rather bold claim for them to make, especially considering the issues that NVIDIA has run up against with compatibility.
Aconselho vivamente a leitura do artigo, muito boas razões para calar os profetas/fanboys da ATI
