VS

GeForce 8500 GT vs Radeon HD 5550

Intro

The GeForce 8500 GT makes use of a 80 nm design. nVidia has clocked the core speed at 450 MHz. The DDR2 RAM runs at a speed of 400 MHz on this model. It features 16 SPUs along with 8 TAUs and 4 ROPs.

Compare those specs to the Radeon HD 5550, which comes with a GPU core clock speed of 550 MHz, and 512 MB of DDR2 memory set to run at 400 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon HD 5550 is a lot (about 144%) more effective at AF than the GeForce 8500 GT. (explain)

Radeon HD 5550 8800 Mtexels/sec
GeForce 8500 GT 3600 Mtexels/sec
Difference: 5200 (144%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5550 is the winner, and very much so. (explain)

Radeon HD 5550 4400 Mpixels/sec
GeForce 8500 GT 1800 Mpixels/sec
Difference: 2600 (144%)

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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number 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 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 the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
