GeForce GTX 860M vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should in theory be a little bit faster than the GeForce GTX 860M in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GTX 860M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 860M should be much (more or less 88%) more effective at anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 35912 (88%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M375X is a better choice, by far. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GTX 860M		12752 Mpixels/sec
	Difference: 3488 (27%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
