GeForce 9600 GSO 384MB vs Radeon HD 4670 512MB

Intro

The GeForce 9600 GSO 384MB uses a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 RAM is set to run at a speed of 800 MHz on this model. It features 96 SPUs along with 48 TAUs and 12 ROPs.

Compare all that to the Radeon HD 4670 512MB, which comes with a GPU core clock speed of 750 MHz, and 512 MB of GDDR4/GDDR3/DDR3/DDR2 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 320(64x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
