[QUOTE="ronvalencia"][QUOTE="trasherhead"] Ok so to sum this up. I'll be using arguments from both sides of the case. RSX is based NV47 aka G70. It supports Open GL 3.0 and Open GL ES 2.0. Some programmers choose to program directly for the GPU and the CPU without using an API. Open GL 3.0 is only supported by G80 chipset and up. This conflicts with the idea that the RSX is only a G70. From this we can conclude that they may have taken some of the features that they already had planed for the G80 and put it into the RSX. We can then think of the RSX as the missing link between the G70 and the G80. trasherhead
OpenGL 3.0 comments are for the alternative APIs and D3D 10 like functionality on Windows XP. It has nothing to do with RSX, therefore there are no conficts for RSX is only NV47/G70 type GPU. Also, note my request on running geometry shaders on RSX. If RSX is the same level as G80 GPU, why would you execute geometry workloads on SPEs? We could compare libGCM vs CUDA 2.0. It seems to be me that certain PS3 sheep doesn't know what G80's basic functionality. So you are ignoring the fact that the base G70 chipset does not support Open GL 3 then? No G70 based PC card can do Open GL 3, yet the RSX can. Im not saying that its a G80 and can do DX10. But from the fact that it can use Open GL 3 tells me that it is more advanced then regular G70. It must in fact be like the 360's GPU, which was the precursor to the R600 chipset which is used today. That isn't saying that it is a R600, but it has SOME of the functionality of the R600. The RSX isn't a G80, but it was the precursor for it and can very likely have some of its functions and ability. So you are ignoring the fact that the NVIDIA says full OpenGL3.0 is only enabled on G80 and up GPUs? NVIDIA OpenGL 3.0 release notes To quote NVIDIA Windows drivers version 181.00 and Linux drivers version 180.11.02 provide full OpenGL 3.0 and GLSL 1.30 support.
The driver download links are at the bottom of this page. OpenGL 3.0 Driver Release Notes You need one of the following graphics cards to get access to the OpenGL 3.0 and GLSL 1.30 functionality:
Desktop Quadro FX 370, 570, 1700, 3700, 4600, 4700x2, 4800, 5600, 5800, Quadro VX200, Quadro CX GeForce 8000 series or higher; GeForce GTX 260, 280
Notebook Quadro FX 360M, 370M, 570M, 770M, 1600M, 1700M, 2700M, 3600M, 3700M GeForce 8000 series or higher
So, where's Geforce 7 in that NVIDIA's release notes? Ignore NVIDIA at your own peril.
