GeForce GT 440 3GB vs Radeon HD 5570

Intro

Compare all of that to the Radeon HD 5570, which makes use of a 40 nm design. AMD has set the core frequency at 650 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.

Radeon HD 5570		13000 Mtexels/sec
	Difference: 1256 (10%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 440 3GB is superior to the Radeon HD 5570, by a large margin. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 9056 (174%)

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 data (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
