GeForce 8800 GTX vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which comes with a clock frequency of 715 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GTX, in theory, should perform a lot faster than the Radeon R7 M260 overall. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 70400 (440%)

Texel Rate

The GeForce 8800 GTX will be much (approximately 114%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 19640 (114%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 8800 GTX is the winner, by far. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 8080 (141%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
