Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 5670
IntroThe GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 RAM runs at a speed of 902 MHz on this particular model. It features 192 SPUs along with 32 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 5670, which comes with GPU clock speed of 775 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5670 should be a bit faster than the GeForce GTS 450 1GB in general. (explain)
Texel RateThe GeForce GTS 450 1GB will be a lot (more or less 62%) better at AF than the Radeon HD 5670. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTS 450 1GB is the winner, and very much so. (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 max amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the 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 video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
