GeForce GTX 460 vs Radeon HD 5750 512MB

Intro

The GeForce GTX 460 has a clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 192-bit memory bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 24 ROPs.

Compare all of that to the Radeon HD 5750 512MB, which features clock speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, 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 higher screen resolutions.

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

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