GeForce GTX 850M vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has clocked the core speed at 825 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 M260X should theoretically 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 much (more or less 77%) faster with regards to 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 850M is superior to the Radeon R7 M260X, by far. (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 max amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
