GeForce 8800 GS vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which comes with a clock speed of 725 MHz and a DDR3 memory speed of 1000 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 8800 GS should perform just a bit faster than the Radeon R7 M265 overall. (explain)

GeForce 8800 GS		38400 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 6400 (20%)

Texel Rate

The GeForce 8800 GS is much (approximately 52%) better at AF than the Radeon R7 M265. (explain)

GeForce 8800 GS		26400 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 9000 (52%)

Pixel Rate

The GeForce 8800 GS is a bit (approximately 14%) more effective at full screen anti-aliasing than the Radeon R7 M265, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 8800 GS		6600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 800 (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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling 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 that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
