GeForce 920M vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which comes with a core clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260X should perform much faster than the GeForce 920M in general. (explain)

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

Texel Rate

The GeForce 920M is a lot (approximately 54%) better at texture filtering than the Radeon R7 M260X. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce 920M is the winner, but it probably won't make a huge difference. (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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
