GeForce 9600 GSO 768MB vs Radeon HD 4670 512MB

Intro

The GeForce 9600 GSO 768MB features core speeds of 550 MHz on the GPU, and 800 MHz on the 768 MB of GDDR3 RAM. It features 96 SPUs along with 48 Texture Address Units and 12 Rasterization Operator Units.

Compare that to the Radeon HD 4670 512MB, which makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a speed of 1000 MHz on this model. It features 320(64x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
