GeForce 8800 GTS (G80) 640MB vs Radeon R7 M360

Intro

Compare that to the Radeon R7 M360, which comes with clock speeds of 1125 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTS (G80) 640MB will be 296% quicker than the Radeon R7 M360 in general, due to its greater data rate. (explain)

GeForce 8800 GTS (G80) 640MB		63360 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 47360 (296%)

Texel Rate

The Radeon R7 M360 is a little bit (more or less 10%) better at AF than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon R7 M360		27000 Mtexels/sec
GeForce 8800 GTS (G80) 640MB		24624 Mtexels/sec
	Difference: 2376 (10%)

Pixel Rate

The GeForce 8800 GTS (G80) 640MB should be a little bit (more or less 14%) more effective at anti-aliasing than the Radeon R7 M360, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 8800 GTS (G80) 640MB		10260 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 1260 (14%)

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 largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If 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 higher screen 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 texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 potential to get to the max fill rate.
