GeForce GT 440 1.5GB vs Radeon HD 5750 512MB

Intro

Compare all of that to the Radeon HD 5750 512MB, which has a core clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

	Difference: 30400 (70%)

Texel Rate

The Radeon HD 5750 512MB will be a lot (approximately 77%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)

Radeon HD 5750 512MB		25200 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 10944 (77%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is a better choice, and very much so. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 3056 (27%)

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 megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
