GeForce 8800 GT 512MB vs Radeon R7 M260

Intro

Compare that to the Radeon R7 M260, which comes with a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 8800 GT 512MB should in theory be a lot superior to the Radeon R7 M260 in general. (explain)

GeForce 8800 GT 512MB		57600 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The GeForce 8800 GT 512MB is quite a bit (more or less 96%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 16440 (96%)

Pixel Rate

The GeForce 8800 GT 512MB should be quite a bit (approximately 68%) more effective at FSAA than the Radeon R7 M260, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 8800 GT 512MB		9600 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 3880 (68%)

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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
