GeForce 920M vs Radeon R9 M375

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375 is 144% quicker than the GeForce 920M in general, due to its greater data rate. (explain)

Radeon R9 M375		35200 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 20800 (144%)

Texel Rate

The Radeon R9 M375 should be much (about 33%) better at anisotropic filtering than the GeForce 920M. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 10072 (33%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M375 is the winner, by far. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 8608 (113%)

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 information (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
