GeForce GTX 960M vs Radeon R9 M270X

Intro

The GeForce GTX 960M makes use of a 28 nm design. nVidia has clocked the core speed at 1096 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon R9 M270X, which features a core clock frequency of 725 MHz and a GDDR5 memory frequency of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Radeon R9 M270X 72000 MB/sec
GeForce GTX 960M 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The GeForce GTX 960M is quite a bit (more or less 51%) more effective at texture filtering than the Radeon R9 M270X. (explain)

GeForce GTX 960M 43840 Mtexels/sec
Radeon R9 M270X 29000 Mtexels/sec
Difference: 14840 (51%)

Pixel Rate

The GeForce GTX 960M will be quite a bit (about 51%) more effective at full screen anti-aliasing than the Radeon R9 M270X, and also able to handle higher resolutions while still performing well. (explain)

GeForce GTX 960M 17536 Mpixels/sec
Radeon R9 M270X 11600 Mpixels/sec
Difference: 5936 (51%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
