GeForce 8800 GT 512MB vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core speed at 825 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific model. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 M260X should be just a bit faster than the GeForce 8800 GT 512MB in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 8800 GT 512MB is much (more or less 70%) better at texture filtering than the Radeon R7 M260X. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 13800 (70%)

Pixel Rate

The GeForce 8800 GT 512MB is much (approximately 45%) faster with regards to AA than the Radeon R7 M260X, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce 8800 GT 512MB		9600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 3000 (45%)

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 data (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
