GeForce 8800 GTS (G80) 320MB vs Radeon R7 M260

Intro

Compare all that to the Radeon R7 M260, which has core clock speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 8800 GTS (G80) 320MB should in theory be a lot superior to the Radeon R7 M260 overall. (explain)

GeForce 8800 GTS (G80) 320MB		63360 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 47360 (296%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB will be a lot (more or less 43%) more effective at AF than the Radeon R7 M260. (explain)

GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 7464 (43%)

Pixel Rate

The GeForce 8800 GTS (G80) 320MB is quite a bit (more or less 79%) more effective at FSAA than the Radeon R7 M260, and also should be capable of handling higher screen resolutions better. (explain)

GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 4540 (79%)

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 information (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
