GeForce GTX 960M vs Radeon R9 M270X

Intro

The GeForce GTX 960M features a GPU core clock 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 Texture Address Units, and 16 ROPs.

Compare all that to the Radeon R9 M270X, which has GPU core speed of 725 MHz, and 2048 MB of GDDR5 RAM set to run at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

GeForce GTX 960M 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The GeForce GTX 960M is much (about 51%) better 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 is a lot (more or less 51%) faster with regards to FSAA than the Radeon R9 M270X, and also will be capable of handling higher screen resolutions without slowing down too much. (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 largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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.
