GeForce 8800 GTS (G92) vs Radeon HD 6750 1GB

Intro

Compare those specs to the Radeon HD 6750 1GB, which comes with a core clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It features 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Radeon HD 6750 1GB		86 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 49 Watts (57%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 1GB is 3% quicker than the GeForce 8800 GTS (G92) in general, due to its higher data rate. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 1920 (3%)

Texel Rate

The GeForce 8800 GTS (G92) will be much (more or less 59%) better at AF than the Radeon HD 6750 1GB. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 15500 (59%)

Pixel Rate

The Radeon HD 6750 1GB is just a bit (about 12%) more effective at FSAA than the GeForce 8800 GTS (G92), and also capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 1200 (12%)

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 (measured in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
