Nvidia GT300: Geforce GTX 380 with 512 Shader ALUs in the DirectX 11 GPU?
Speculations about Nvidia's next graphics card generation, based on the GT300 (Geforce GTX 380) with DirectX 11 support, have not been confirmed up to now. The latest rumors say that the GT300 will have 512 Shader ALUs.
The new high-end graphics cards, Geforce GTX 380 (GT300) or Radeon HD 5870 (RV870), are unlikely to be released before DirectX 11 has finally hit the markets. But they are nevertheless expected to deliver a noticeable performance benefit compared to the current models GTX 275 or HD 4890.
According to the latest rumors Nvidia's GT300, that will probably be a completely new developed chip, will have 512 Shader ALUs that are positioned in 16 packs with 32 units each. Furthermore the GT300 is said to support DirectX 11 and Shader Model 3.1 as well as OpenCL. The 512 Shader ALUs are supposed to be placed as a MIMD solution (Multiple Instructions, Multiple Data) and not as a SIMD solution (Single Instruction, Multiple Data).
