GeForce GTX 880M vs Radeon R7 M265

Intro

Compare those specifications to the Radeon R7 M265, which has a core clock speed of 725 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Radeon R7 M265		32000 MB/sec
	Difference: 96000 (300%)

Texel Rate

The GeForce GTX 880M should be much (more or less 602%) more effective at anisotropic filtering than the Radeon R7 M265. (explain)

GeForce GTX 880M		122112 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 104712 (602%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 880M is a better choice, and very much so. (explain)

GeForce GTX 880M		30528 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 24728 (426%)

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 MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
