Now that NVIDIA’s has announced its newest GPU architecture (the GeForce GTX 200 series), interesting architectural details are popping up on the web. The best writeup I’ve found is by AnandTech. In the past, such detailed writeups would have required a lot of reverse-engineering and guessing. Nowadays, a lot of the detailed low-level information is forthcoming directly from NVIDIA itself. This is probably due to the desire to promote GPGPU programming models such as CUDA, which require low-level hardware knowledge to write efficient code. The architecture details make for some interesting reading.
