GeForce 9600 GT 512MB vs Radeon HD 6670 (OEM) 1GB

Intro

The GeForce 9600 GT 512MB has a GPU core clock speed of 650 MHz, and the 512 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is made up of 64 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
