GeForce GTX 960M vs Radeon R9 M270X

Intro

The GeForce GTX 960M uses a 28 nm design. nVidia has clocked the core frequency at 1096 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the Radeon R9 M270X, which uses a 28 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

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

Texel Rate

The GeForce GTX 960M should be a lot (more or less 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

The GeForce GTX 960M should be quite a bit (approximately 51%) faster with regards to anti-aliasing than the Radeon R9 M270X, and should be able to handle higher 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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
