GeForce 920M vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M375X should theoretically be much superior to the GeForce 920M in general. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M375X will be quite a bit (approximately 33%) better at AF than the GeForce 920M. (explain)

Radeon R9 M375X		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 M375X is superior to the GeForce 920M, by far. (explain)

Radeon R9 M375X		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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
