GeForce GT 440 1.5GB vs Radeon HD 5850

Intro

Compare all of that to the Radeon HD 5850, which comes with GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 256-bit bus. It also is comprised of 1440(288x5) SPUs, 72 TAUs, and 32 Raster Operation Units.

Memory Bandwidth

The Radeon HD 5850, in theory, should be quite a bit faster than the GeForce GT 440 1.5GB overall. (explain)

Radeon HD 5850		128000 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 84800 (196%)

Texel Rate

The Radeon HD 5850 should be much (about 266%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)

Radeon HD 5850		52200 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 37944 (266%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5850 is a better choice, by a large margin. (explain)

Radeon HD 5850		23200 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 8944 (63%)

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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
