GeForce GTX 960M vs Radeon R9 M265X

Intro

The GeForce GTX 960M features a GPU core clock speed of 1096 MHz, and the 2048 MB of GDDR5 memory is set to run at 1000 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare those specs to the Radeon R9 M265X, which comes with GPU clock speed of 575 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

The Radeon R9 M265X should theoretically perform just a bit faster than the GeForce GTX 960M overall. (explain)

Radeon R9 M265X 72000 MB/sec
GeForce GTX 960M 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The GeForce GTX 960M is much (more or less 91%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 960M 43840 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 20840 (91%)

Pixel Rate

The GeForce GTX 960M is quite a bit (about 91%) faster with regards to AA than the Radeon R9 M265X, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 960M 17536 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 8336 (91%)

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 max amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of 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.
