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

Intro

The GeForce 9600 GT 512MB comes with a GPU core speed of 650 MHz, and the 512 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also is comprised of 64 Stream Processors, 32 Texture Address Units, and 16 ROPs.

Compare that to the Radeon HD 6670 (OEM) 1GB, which comes with a clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It features 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
