GeForce 9800 GTX vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 RAM runs at a frequency of 1150 MHz on this specific card. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

Texel Rate

The GeForce 9800 GTX will be a lot (more or less 71%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 18000 (71%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is the winner, but only just. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 400 (4%)

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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, 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 worked out by multiplying the total number of texture units by the core speed of the chip. The higher 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 amount of pixels the graphics card could possibly write to its local memory per 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant 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.
