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

Intro

The GeForce 8800 GTS (G80) 320MB comes with a GPU core clock speed of 513 MHz, and the 320 MB of GDDR3 RAM is set to run at 792 MHz through a 320-bit bus. It also is made up of 96 SPUs, 48 TAUs, and 20 Raster Operation Units.

Compare those specs to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

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

Texel Rate

The GeForce 8800 GTS (G80) 320MB should be a lot (about 24%) faster with regards to 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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
