GeForce GTX 880M vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which features GPU clock speed of 825 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 880M should be much faster than the Radeon R7 M260X overall. (explain)

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

Texel Rate

The GeForce GTX 880M will be quite a bit (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

If using a high resolution is important to you, then the GeForce GTX 880M is the winner, by far. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends 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.
