GeForce 920M vs Radeon R7 370 4G

Intro

Compare those specifications to the Radeon R7 370 4G, which features GPU core speed of 975 MHz, and 4096 MB of GDDR5 RAM running at 1400 MHz through a 256-bit bus. It also is comprised of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 370 4G should be 1144% faster than the GeForce 920M in general, because of its greater data rate. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 164800 (1144%)

Texel Rate

The Radeon R7 370 4G should be much (more or less 104%) better at texture filtering than the GeForce 920M. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 31872 (104%)

Pixel Rate

The Radeon R7 370 4G will be quite a bit (about 309%) better at AA than the GeForce 920M, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 23568 (309%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number 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 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
