GeForce 8800 GT 512MB vs Radeon Pro Duo

Intro

Compare all that to the Radeon Pro Duo, which has GPU core speed of 1000 MHz, and 4096 MB of HBM RAM running at 500 MHz through a 4096-bit bus. It also is comprised of 4096 Stream Processors, 256 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB		105 Watts
Radeon Pro Duo		350 Watts
	Difference: 245 Watts (233%)

Memory Bandwidth

Theoretically speaking, the Radeon Pro Duo should be 1678% quicker than the GeForce 8800 GT 512MB overall, due to its higher bandwidth. (explain)

Radeon Pro Duo		1024000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 966400 (1678%)

Texel Rate

The Radeon Pro Duo will be quite a bit (about 1424%) more effective at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon Pro Duo		512000 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 478400 (1424%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon Pro Duo is superior to the GeForce 8800 GT 512MB, by a large margin. (explain)

Radeon Pro Duo		128000 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 118400 (1233%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
