GeForce 8800 GT 512MB vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which has clock speeds of 715 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 speaking, the GeForce 8800 GT 512MB will be 260% faster than the Radeon R7 M260 in general, due to its higher bandwidth. (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 much (more or less 96%) better at 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

If running with high levels of AA is important to you, then the GeForce 8800 GT 512MB is superior to the Radeon R7 M260, and very much so. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
