GeForce 8500 GT vs Radeon HD 4550 512MB

Intro

The GeForce 8500 GT comes with a GPU core speed of 450 MHz, and the 512 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also features 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Compare those specifications to the Radeon HD 4550 512MB, which comes with a core clock frequency of 600 MHz and a GDDR3 memory speed of 800 MHz. It also features a 64-bit bus, and uses a 55 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4550 512MB 25 Watts
GeForce 8500 GT 45 Watts
Difference: 20 Watts (80%)

Memory Bandwidth

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

Texel Rate

The Radeon HD 4550 512MB will be a lot (approximately 33%) more effective at texture filtering than the GeForce 8500 GT. (explain)

Radeon HD 4550 512MB 4800 Mtexels/sec
GeForce 8500 GT 3600 Mtexels/sec
Difference: 1200 (33%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 4550 512MB is the winner, by a large margin. (explain)

Radeon HD 4550 512MB 2400 Mpixels/sec
GeForce 8500 GT 1800 Mpixels/sec
Difference: 600 (33%)

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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure 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 graphics 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 maximum number of pixels that 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 amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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.
