GeForce 8800 GTX vs Radeon R7 260X

Intro

Compare all of that to the Radeon R7 260X, which has clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

GeForce 8800 GTX		86400 MB/sec
	Difference: 17600 (20%)

Texel Rate

The Radeon R7 260X is quite a bit (more or less 67%) more effective at AF than the GeForce 8800 GTX. (explain)

Radeon R7 260X		61600 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 24800 (67%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 260X is a better choice, by a large margin. (explain)

Radeon R7 260X		17600 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 3800 (28%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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.
