Talk:Radeon R800
From Wikipedia, the free encyclopedia
[edit] Rumours
Based on 45 nm manufacturing process by TSMC, the RV870 will see memory amount to the magnitudes of GBytes, and possible additions of texture units, texture caches and ROPs. --202.40.157.145 (talk) 03:46, 5 May 2008 (UTC)
- initial planning 1000 SPUs, continue to be based on the Radeon R600 architecture as the fourth generation of ATI's Unified Shader architecture (First generation being Xenos/C1, second generation being Radeon R600 and RV670 families, the third generation being Radeon R700 family). --202.40.157.145 (talk) 05:28, 21 May 2008 (UTC)

- Dual GPU version also available, with memory sharing across two GPUs.

- 1 Unified Shaders (Vertex shader/Geometry shader/Pixel shader) : Texture mapping unit : Render Output unit
