GeForce GTX 960M vs Radeon R9 M270X

Intro

Compare that to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M270X should perform a bit faster than the GeForce GTX 960M in general. (explain)

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

Texel Rate

The GeForce GTX 960M should be quite a bit (more or less 51%) faster with regards to 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

If running with a high resolution is important to you, then the GeForce GTX 960M is the winner, by a large margin. (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB 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, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, 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 number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The figure 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
