Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 3850 X2
IntroThe GeForce GT 340 1GB features core clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs as well as 32 TAUs and 8 ROPs.Compare those specifications to the Radeon HD 3850 X2, which uses a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 memory is set to run at a frequency of 828 MHz on this particular model. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3850 X2 should theoretically be quite a bit better than the GeForce GT 340 1GB in general. (explain)
Texel RateThe Radeon HD 3850 X2 is quite a bit (more or less 21%) more effective at anisotropic filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon HD 3850 X2 should be much (approximately 386%) more effective at FSAA than the GeForce GT 340 1GB, and also will be 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
