Ein paar neue Spekulationen zum ATI R600:
- Auch unter DX9 schneller als die X1900:
- Weitere 20-25% Mehrleistung zu erwarten unter DX10 / mit Unified Shader
- 64 Unified Shader, 16 Textureinheiten, GDDR4
- Laut ATI dem G80 überlegen, da mehr Shader und echte Unified Shader (nVidia: Hybrid Shader)

- Taktraten um 1 Gigahertz
- 65 Nanometer
- R600 gegen Dezember, G80 ca. drei Monate früher

Xbitlabs schrieb:“The R600 will be [absolutely] the fastest DirectX 9 chip that we had ever built,” said Richard Huddy, the head of ATI Technologies’ software developers relations department, at a press conference in London, UK.
Mr. Huddy was asked whether the R600’s already well-known unified shader architecture will suit well for the wide-spread DirectX 9 games, which were developed with dedicated pixel and vertex processors in mind. The answer implies that users, who will buy the R600-based graphics cards early, will get top-class performance even in existing applications.
- Weitere 20-25% Mehrleistung zu erwarten unter DX10 / mit Unified Shader
Mr. Huddy said that Xbox 360 game console, which sports developed by ATI Xenos graphics core with unified shader architecture and 48 shader processors, loses 20% to 25% performance in pixel-shader limited games, when its graphics chip is configured as non-unified, e.g.,16 processors work strictly on vertex shaders, whereas 32 are assigned for pixel shaders.
- 64 Unified Shader, 16 Textureinheiten, GDDR4
The code-named R600 visual processing unit may repeat the success of its grand-grand predecessor, as, according to sources familiar with the plans of ATI Technologies as well as some media reports, ATI R600 will have 64 unified shader processors – an unprecedented number so far, 16 texture units – inline with today’s GPUs, clock-speed beyond 650MHz and support for high-speed GDDR4 memory controller.
- Laut ATI dem G80 überlegen, da mehr Shader und echte Unified Shader (nVidia: Hybrid Shader)
Rival Nvidia G80 will have lower amount of shader processors and will also have “hybrid”, not unified, micro-architecture. Neither ATI, nor Nvidia commented on specs of future products.

The Inquirer schrieb:ATI is working hard on R600. It won't finish it until the end of the year but it aims to make the fastest chip to date. We heard that the chip might achieve and even surpass the magical 1000MHz clock.
- 65 Nanometer
The fastest that Nvidia and ATI can do with 90 nanometres is around 650 to 700MHz and we know that you won't be able to overclock much more with a 90 nanometre chip. This may mean that R600 will be a 65 nanometre component.
- R600 gegen Dezember, G80 ca. drei Monate früher
We expect that Nvidia might introduce its G80 a few months before ATI, we expect G80 at late summer or early autumn, while we know that R600 wont see the face of the earth until late Q4. Things can always get delayed, as you know.
