GeForce 8800 GT 1GB vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which comes with 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 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GT 1GB is 260% faster than the Radeon R7 M260 overall, due to its higher data rate. (explain)

GeForce 8800 GT 1GB		57600 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The GeForce 8800 GT 1GB will be quite a bit (about 96%) more effective at texture filtering than the Radeon R7 M260. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 16440 (96%)

Pixel Rate

The GeForce 8800 GT 1GB should be quite a bit (approximately 68%) better at FSAA than the Radeon R7 M260, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce 8800 GT 1GB		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 (in units of MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
