Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.

4 Responses to “GeForce GTX 460 vs Radeon HD 6950 2GB”Sorry to say but your data is incorrect. The GTX460's shader clock is doulbe the core clock. In AIDA64 with a GTX460 HAWK at 925/1850 core/shader 2250 mem
Texel Rate - 155400Mtex/s
Pixel Rate - 29600Mpix/s
Memory bandwidth - 140.6GB/s
@Levi - There are actually 2 different versions of the GTX 460. Here we have listed the 192-bit 768MB version, the HAWK is based on the 256-bit 1GB version.

Fair enough, maybe it should be noted in the title.
Good point... but it'd be a bit of an admin nightmare to change the title now (due to custom database code). 🙁
What I can do is add a little note at the top of this page though.
