GeForce 920M vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which comes with a clock speed of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X should in theory perform much faster than the GeForce 920M in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M365X is much (approximately 21%) more effective at anisotropic filtering than the GeForce 920M. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 6472 (21%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M365X is superior to the GeForce 920M, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 7168 (94%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
