GeForce 920M vs Radeon R7 M260X

Intro

Compare those specifications to the Radeon R7 M260X, which features clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should be 344% quicker than the GeForce 920M overall, because of its higher data rate. (explain)

Radeon R7 M260X		64000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The GeForce 920M will be quite a bit (approximately 54%) faster with regards to AF than the Radeon R7 M260X. (explain)

GeForce 920M		30528 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 10728 (54%)

Pixel Rate

The GeForce 920M is just a bit (more or less 16%) better at full screen anti-aliasing than the Radeon R7 M260X, and will be capable of handling higher resolutions while still performing well. (explain)

GeForce 920M		7632 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 1032 (16%)

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: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
