Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 4870 2GB
IntroThe GeForce GT 450 (OEM) features a GPU core speed of 790 MHz, and the 1536 MB of GDDR5 RAM is set to run at 1000 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 TAUs, and 24 ROPs.Compare all that to the Radeon HD 4870 2GB, which comes with core speeds of 750 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 memory. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4870 2GB should perform a little bit faster than the GeForce GT 450 (OEM) overall. (explain)
Texel RateThe Radeon HD 4870 2GB is quite a bit (more or less 58%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GT 450 (OEM) is a better choice, by far. (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 information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
