GeForce GTX 880M vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which comes with core clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX 880M should be quite a bit faster than the Radeon R7 M260X in general. (explain)

GeForce GTX 880M		128000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 64000 (100%)

Texel Rate

The GeForce GTX 880M should be much (approximately 517%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 880M		122112 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 102312 (517%)

Pixel Rate

The GeForce GTX 880M should be a lot (about 363%) more effective at FSAA than the Radeon R7 M260X, and will be able to handle higher resolutions better. (explain)

GeForce GTX 880M		30528 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 23928 (363%)

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 (in units of MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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