GeForce GTX 960M vs Radeon R9 M270X

Intro

The GeForce GTX 960M comes with a GPU core speed of 1096 MHz, and the 2048 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare that to the Radeon R9 M270X, which comes with core speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M270X is 13% faster than the GeForce GTX 960M in general, because of its higher data rate. (explain)

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 (about 51%) faster with regards to AF than the Radeon R9 M270X. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960M is a better choice, and very much so. (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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
