Compare any two graphics cards:
GeForce 8500 GT vs Radeon HD 6450 (OEM)
IntroThe GeForce 8500 GT features a core clock frequency of 450 MHz and a DDR2 memory frequency of 400 MHz. It also uses a 128-bit memory bus, and makes use of a 80 nm design. It is made up of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.Compare all that to the Radeon HD 6450 (OEM), which has a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also is made up of 160 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so in theory they should perform the same. (explain)
Texel RateThe Radeon HD 6450 (OEM) will be a lot (approximately 39%) faster with regards to AF than the GeForce 8500 GT. (explain)
Pixel RateThe Radeon HD 6450 (OEM) should be a lot (more or less 39%) more effective at FSAA than the GeForce 8500 GT, and able to handle higher screen resolutions more effectively. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core 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 maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
