Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs Radeon HD 6450 (OEM)
IntroThe GeForce 8600 GT 256MB DDR2 comes with core speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specifications to the Radeon HD 6450 (OEM), which has clock speeds of 625 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 160 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same memory bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe GeForce 8600 GT 256MB DDR2 will be quite a bit (about 73%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce 8600 GT 256MB DDR2 will be quite a bit (more or less 73%) better at full screen anti-aliasing than the Radeon HD 6450 (OEM), and also able to handle higher resolutions while still performing well. (explain)
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. Price Comparison

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, 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 amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
