GeForce 920M vs Radeon R7 M265

Intro

Compare all that to the Radeon R7 M265, which features a clock speed of 725 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M265 is 122% quicker than the GeForce 920M in general, because of its higher bandwidth. (explain)

Radeon R7 M265		32000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 17600 (122%)

Texel Rate

The GeForce 920M should be quite a bit (approximately 75%) better at AF than the Radeon R7 M265. (explain)

GeForce 920M		30528 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 13128 (75%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 920M is the winner, and very much so. (explain)

GeForce 920M		7632 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 1832 (32%)

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 transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
