Geforce GTX 760 vs Radeon HD 6950

Intro

The Geforce GTX 760 comes with a core clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

Compare all that to the Radeon HD 6950, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also is comprised of 1408 SPUs, 88 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
