GeForce 8600 GT 256MB DDR2 vs Radeon HD 4550 256MB

Intro

The GeForce 8600 GT 256MB DDR2 has a GPU clock speed of 540 MHz, and the 256 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Compare those specs to the Radeon HD 4550 256MB, which has a core clock frequency of 600 MHz and a DDR3 memory speed of 800 MHz. It also uses a 64-bit bus, and uses a 55 nm design. It features 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4550 256MB 25 Watts
GeForce 8600 GT 256MB DDR2 47 Watts
Difference: 22 Watts (88%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce 8600 GT 256MB DDR2 will be quite a bit (approximately 80%) more effective at AF than the Radeon HD 4550 256MB. (explain)

GeForce 8600 GT 256MB DDR2 8640 Mtexels/sec
Radeon HD 4550 256MB 4800 Mtexels/sec
Difference: 3840 (80%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 8600 GT 256MB DDR2 is the winner, and very much so. (explain)

GeForce 8600 GT 256MB DDR2 4320 Mpixels/sec
Radeon HD 4550 256MB 2400 Mpixels/sec
Difference: 1920 (80%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
