GeForce 920M vs Radeon HD 5750 512MB

Intro

Compare all of that to the Radeon HD 5750 512MB, which makes use of a 40 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 RAM runs at a speed of 1150 MHz on this card. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 5750 512MB should in theory perform a lot faster than the GeForce 920M in general. (explain)

Radeon HD 5750 512MB		73600 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 59200 (411%)

Texel Rate

The GeForce 920M is much (more or less 21%) better at texture filtering than the Radeon HD 5750 512MB. (explain)

GeForce 920M		30528 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 5328 (21%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 5750 512MB is the winner, by far. (explain)

Radeon HD 5750 512MB		11200 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 3568 (47%)

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 max amount of information (in units of MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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