GeForce 8800 GTS (G80) 320MB vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which uses a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this specific model. It features 720 SPUs along with 36 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
GeForce 8800 GTS (G80) 320MB		143 Watts
	Difference: 57 Watts (66%)

Memory Bandwidth

The Radeon HD 6750, in theory, should perform a small bit faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 8800 GTS (G80) 320MB		63360 MB/sec
	Difference: 640 (1%)

Texel Rate

The Radeon HD 6750 will be a small bit (more or less 6%) more effective at anisotropic filtering than the GeForce 8800 GTS (G80) 320MB. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 1476 (6%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6750 is superior to the GeForce 8800 GTS (G80) 320MB, but it probably won't make a huge difference. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
	Difference: 1340 (13%)

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 (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number 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 clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
