Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M265X should theoretically perform a lot faster than the GeForce 8800 GT 1GB in general. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The GeForce 8800 GT 1GB will be much (more or less 46%) faster with regards to AF than the Radeon R9 M265X. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 10600 (46%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 8800 GT 1GB is superior to the Radeon R9 M265X, but it probably won't make a huge difference. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 400 (4%)

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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
