GeForce 8800 GTS (G80) 320MB vs Radeon R7 M260X

Intro

The GeForce 8800 GTS (G80) 320MB uses a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 RAM is set to run at a speed of 792 MHz on this model. It features 96 SPUs as well as 48 TAUs and 20 Rasterization Operator Units.

Compare those specs to the Radeon R7 M260X, which comes with a clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

GeForce 8800 GTS (G80) 320MB 63360 MB/sec
Difference: 640 (1%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB is much (more or less 24%) better at texture filtering than the Radeon R7 M260X. (explain)

GeForce 8800 GTS (G80) 320MB 24624 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 4824 (24%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 8800 GTS (G80) 320MB is the winner, by far. (explain)

GeForce 8800 GTS (G80) 320MB 10260 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 3660 (55%)

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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
