GeForce GTX 850M vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which comes with a core clock speed of 825 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be much faster than the GeForce GTX 850M in general. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce GTX 850M		32000 MB/sec
	Difference: 32000 (100%)

Texel Rate

The GeForce GTX 850M should be quite a bit (approximately 77%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

GeForce GTX 850M		35040 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 15240 (77%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 850M is superior to the Radeon R7 M260X, by a large margin. (explain)

GeForce GTX 850M		14016 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 7416 (112%)

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 largest amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the potential to reach the maximum fill rate.
