GeForce 940M vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which features a core clock speed of 1015 MHz and a DDR3 memory frequency of 1100 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M375 should perform quite a bit faster than the GeForce 940M overall. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 19200 (120%)

Texel Rate

The Radeon R9 M375 will be much (more or less 58%) more effective at texture filtering than the GeForce 940M. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 14872 (58%)

Pixel Rate

The Radeon R9 M375 should be much (about 89%) better at anti-aliasing than the GeForce 940M, and will be able to handle higher resolutions better. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 7664 (89%)

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 largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen 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 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
