GeForce 920M vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which features GPU core speed of 1015 MHz, and 4096 MB of DDR3 memory running at 1100 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375 should theoretically be a lot superior to the GeForce 920M in general. (explain)

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

Texel Rate

The Radeon R9 M375 is much (about 33%) more effective at AF than the GeForce 920M. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375 is superior to the GeForce 920M, and very much so. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
