GeForce 8800 GTS (G80) 320MB vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which has core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GTS (G80) 320MB, in theory, should be a lot faster than the Radeon R7 M265 overall. (explain)

GeForce 8800 GTS (G80) 320MB		63360 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 31360 (98%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB should be quite a bit (about 42%) more effective at AF than the Radeon R7 M265. (explain)

GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 7224 (42%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G80) 320MB is the winner, by a large margin. (explain)

GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 4460 (77%)

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 (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
