Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 3850 256MB
IntroThe GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 RAM works at a speed of 902 MHz on this specific card. It features 192 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 3850 256MB, which features a clock speed of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTS 450 1GB should theoretically be a bit better than the Radeon HD 3850 256MB in general. (explain)
Texel RateThe GeForce GTS 450 1GB will be quite a bit (about 134%) more effective at texture filtering than the Radeon HD 3850 256MB. (explain)
Pixel RateThe GeForce GTS 450 1GB should be just a bit (about 17%) better at FSAA than the Radeon HD 3850 256MB, and also able to handle higher resolutions while still performing well. (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

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units 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 in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
