Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 6450 (OEM)
IntroThe GeForce 8600 GT 512MB DDR2 comes with core clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the Radeon HD 6450 (OEM), which has a clock frequency of 625 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 64-bit memory bus, and makes use of a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe GeForce 8600 GT 512MB DDR2 is quite a bit (approximately 73%) faster with regards to texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce 8600 GT 512MB DDR2 will be a lot (approximately 73%) faster with regards to AA than the Radeon HD 6450 (OEM), and also will be able to handle higher screen resolutions better. (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

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to reach the max fill rate.
