GeForce 8800 GT 256MB vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which comes with core clock speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 GT 256MB is 180% faster than the Radeon R7 M260 in general, because of its greater data rate. (explain)

GeForce 8800 GT 256MB		44800 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 28800 (180%)

Texel Rate

The GeForce 8800 GT 256MB is quite a bit (approximately 96%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

GeForce 8800 GT 256MB		33600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 16440 (96%)

Pixel Rate

The GeForce 8800 GT 256MB should be quite a bit (approximately 68%) more effective at AA than the Radeon R7 M260, and will be able to handle higher resolutions more effectively. (explain)

GeForce 8800 GT 256MB		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 largest amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 are processed per second. This is worked out by multiplying the total amount of texture units 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 processed per second.

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