GeForce 920M vs Radeon R7 370 4G

Intro

Compare all of that to the Radeon R7 370 4G, which makes use of a 28 nm design. AMD has set the core speed at 975 MHz. The GDDR5 memory is set to run at a speed of 1400 MHz on this particular model. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 370 4G, in theory, should be much faster than the GeForce 920M in general. (explain)

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

Texel Rate

The Radeon R7 370 4G is much (approximately 104%) better at AF than the GeForce 920M. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 370 4G is the winner, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out 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 4 instead. The higher the bandwidth is, the faster 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 are processed per second. This 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
