GeForce GTX 860M vs Radeon R9 M270X

Intro

The GeForce GTX 860M uses a 28 nm design. nVidia has clocked the core speed at 797 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this model. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Compare those specifications to the Radeon R9 M270X, which comes with clock speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X should be 13% quicker than the GeForce GTX 860M in general, due to its higher data rate. (explain)

Radeon R9 M270X 72000 MB/sec
GeForce GTX 860M 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The GeForce GTX 860M is much (more or less 164%) faster with regards to anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce GTX 860M 76512 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 47512 (164%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 860M is a better choice, not by a very large margin though. (explain)

GeForce GTX 860M 12752 Mpixels/sec
Radeon R9 M270X 11600 Mpixels/sec
Difference: 1152 (10%)

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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.
