GeForce 8800 GT 512MB vs Radeon HD 6750 1GB

Intro

Compare those specs to the Radeon HD 6750 1GB, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular card. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750 1GB		86 Watts
GeForce 8800 GT 512MB		105 Watts
	Difference: 19 Watts (22%)

Memory Bandwidth

Performance-wise, the Radeon HD 6750 1GB should in theory be just a bit better than the GeForce 8800 GT 512MB overall. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 8800 GT 512MB will be a lot (more or less 29%) more effective at anisotropic filtering than the Radeon HD 6750 1GB. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 7500 (29%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is superior to the GeForce 8800 GT 512MB, and very much so. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 2000 (21%)

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 max amount of information (measured in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
