GeForce GTX 860M vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X should be 13% quicker than the GeForce GTX 860M overall, because of its higher data rate. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce GTX 860M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 860M is quite a bit (about 139%) faster with regards to AF than the Radeon R9 M370X. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 44512 (139%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M370X is superior to the GeForce GTX 860M, not by a very large margin though. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce GTX 860M		12752 Mpixels/sec
	Difference: 48 (0%)

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 information (counted in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be 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 better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
