Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 3870 512MB
IntroThe GeForce GTS 450 1GB uses a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 memory runs at a speed of 902 MHz on this particular card. It features 192 SPUs along with 32 TAUs and 16 ROPs.Compare all that to the Radeon HD 3870 512MB, which has core clock speeds of 775 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthIn theory, the GeForce GTS 450 1GB is 0% quicker than the Radeon HD 3870 512MB in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTS 450 1GB should be a lot (more or less 102%) more effective at anisotropic filtering than the Radeon HD 3870 512MB. (explain)
Pixel RateThe GeForce GTS 450 1GB will be a bit (about 1%) faster with regards to full screen anti-aliasing than the Radeon HD 3870 512MB, and able to handle higher resolutions without slowing down too much. (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 max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
