Geforce GTX 680 vs Radeon HD 5750 1GB

Intro

Compare those specs to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 memory is set to run at a speed of 1150 MHz on this specific card. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.

	Difference: 118656 (161%)

Texel Rate

The Geforce GTX 680 should be much (more or less 411%) better at AF than the Radeon HD 5750 1GB. (explain)

Geforce GTX 680		128768 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 103568 (411%)

Pixel Rate

The Geforce GTX 680 should be quite a bit (about 187%) more effective at AA than the Radeon HD 5750 1GB, and also should be capable of handling higher screen resolutions better. (explain)

Geforce GTX 680		32192 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 20992 (187%)

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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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