GeForce GTX 960M vs Radeon R9 M270X

Intro

The GeForce GTX 960M comes with a clock frequency of 1096 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 ROPs.

Compare all that to the Radeon R9 M270X, which uses a 28 nm design. AMD has set the core speed at 725 MHz. The GDDR5 memory runs at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M270X should theoretically be a little bit faster than the GeForce GTX 960M overall. (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%) better at anisotropic 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 should be much (more or less 51%) better at anti-aliasing than the Radeon R9 M270X, and should be capable of handling higher screen 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 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 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 processed per 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 this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
