Compare any two graphics cards:
VS

GeForce 8600 GS (OEM) vs Radeon HD 5450

Intro

The GeForce 8600 GS (OEM) features a clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also features a 128-bit bus, and uses a 80 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Compare those specifications to the Radeon HD 5450, which comes with core clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

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

Texel Rate

The GeForce 8600 GS (OEM) is a lot (about 66%) more effective at AF than the Radeon HD 5450. (explain)

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

Pixel Rate

The GeForce 8600 GS (OEM) should be quite a bit (approximately 66%) faster with regards to FSAA than the Radeon HD 5450, and should be capable of handling higher screen resolutions without losing too much performance. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
