GeForce 8600 GT 512MB DDR2 vs Radeon HD 4550 512MB

Intro

The GeForce 8600 GT 512MB DDR2 has a GPU core speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare that to the Radeon HD 4550 512MB, which has core clock speeds of 600 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4550 512MB 25 Watts
GeForce 8600 GT 512MB DDR2 47 Watts
Difference: 22 Watts (88%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The GeForce 8600 GT 512MB DDR2 will be quite a bit (more or less 80%) faster with regards to AF than the Radeon HD 4550 512MB. (explain)

GeForce 8600 GT 512MB DDR2 8640 Mtexels/sec
Radeon HD 4550 512MB 4800 Mtexels/sec
Difference: 3840 (80%)

Pixel Rate

The GeForce 8600 GT 512MB DDR2 is a lot (more or less 80%) better at FSAA than the Radeon HD 4550 512MB, and capable of handling higher screen resolutions while still performing well. (explain)

GeForce 8600 GT 512MB DDR2 4320 Mpixels/sec
Radeon HD 4550 512MB 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 data (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
