Compare any two graphics cards:
VS

GeForce 8600 GS (OEM) vs Radeon HD 5450

Intro

The GeForce 8600 GS (OEM) comes with a core clock speed of 540 MHz and a DDR2 memory speed of 400 MHz. It also uses a 128-bit memory bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare those specifications to the Radeon HD 5450, which comes with a core clock frequency of 650 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 64-bit bus, and makes use of a 40 nm design. It is comprised of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5450 19 Watts
GeForce 8600 GS (OEM) 47 Watts
Difference: 28 Watts (147%)

Memory Bandwidth

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

Texel Rate

The GeForce 8600 GS (OEM) will be much (about 66%) faster with regards to anisotropic filtering than the Radeon HD 5450. (explain)

GeForce 8600 GS (OEM) 8640 Mtexels/sec
Radeon HD 5450 5200 Mtexels/sec
Difference: 3440 (66%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 8600 GS (OEM) is the winner, by a large margin. (explain)

GeForce 8600 GS (OEM) 4320 Mpixels/sec
Radeon HD 5450 2600 Mpixels/sec
Difference: 1720 (66%)

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 information (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
