GeForce GTX 860M vs Radeon R9 M370X

Intro

The GeForce GTX 860M comes with a core clock frequency of 797 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 16 Raster Operation Units.

Compare all of that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

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

Texel Rate

The GeForce GTX 860M is much (approximately 139%) faster with regards to anisotropic filtering than the Radeon R9 M370X. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M370X is a better choice, though only just barely. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
