GeForce GTX 960M vs Radeon R9 M375

Intro

Compare all that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 RAM is set to run at a frequency of 1100 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Radeon R9 M375		40600 Mtexels/sec
	Difference: 3240 (8%)

Pixel Rate

The GeForce GTX 960M is a little bit (more or less 8%) faster with regards to anti-aliasing than the Radeon R9 M375, and capable of handling higher resolutions more effectively. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 1296 (8%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 ability to get to the max fill rate.
