GeForce GTX 960 vs Radeon HD 6850

Intro

The GeForce GTX 960 has a GPU core speed of 1127 MHz, and the 2048 MB of GDDR5 memory is set to run at 1750 MHz through a 128-bit bus. It also features 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Compare that to the Radeon HD 6850, which features a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is comprised of 960 Stream Processors, 48 Texture Address Units, and 32 ROPs.

GeForce GTX 960 112000 MB/sec
Difference: 16000 (14%)

Texel Rate

The GeForce GTX 960 will be quite a bit (more or less 94%) better at anisotropic filtering than the Radeon HD 6850. (explain)

GeForce GTX 960 72128 Mtexels/sec
Radeon HD 6850 37200 Mtexels/sec
Difference: 34928 (94%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 960 is a better choice, by far. (explain)

GeForce GTX 960 36064 Mpixels/sec
Radeon HD 6850 24800 Mpixels/sec
Difference: 11264 (45%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
