GeForce 8800 GTX vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which uses a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific card. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 GTX should be 35% faster than the Radeon R7 M260X overall, because of its higher data rate. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 22400 (35%)

Texel Rate

The GeForce 8800 GTX should be a lot (approximately 86%) better at AF than the Radeon R7 M260X. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 17000 (86%)

Pixel Rate

The GeForce 8800 GTX should be quite a bit (more or less 109%) better at FSAA than the Radeon R7 M260X, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 7200 (109%)

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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
