GeForce 8800 GS vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which has core speeds of 725 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 8800 GS should perform a little bit faster than the Radeon R7 M265 in general. (explain)

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

Texel Rate

The GeForce 8800 GS is much (more or less 52%) better at texture filtering than the Radeon R7 M265. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GS is the winner, though only just barely. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 applied in one second. This number is calculated by multiplying the total 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
