GeForce 9600 GSO 768MB vs Radeon Pro Duo

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 768MB		84 Watts
Radeon Pro Duo		350 Watts
	Difference: 266 Watts (317%)

Memory Bandwidth

In theory, the Radeon Pro Duo will be 2567% quicker than the GeForce 9600 GSO 768MB in general, because of its higher bandwidth. (explain)

Radeon Pro Duo		1024000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 985600 (2567%)

Texel Rate

The Radeon Pro Duo should be a lot (more or less 1839%) better at AF than the GeForce 9600 GSO 768MB. (explain)

Radeon Pro Duo		512000 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 485600 (1839%)

Pixel Rate

The Radeon Pro Duo should be a lot (approximately 1839%) better at AA than the GeForce 9600 GSO 768MB, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon Pro Duo		128000 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 121400 (1839%)

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 information (measured in MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
