Compare any two graphics cards:
GeForce GT 340 1GB vs Radeon HD 4850 2GB
IntroThe GeForce GT 340 1GB comes with a GPU clock speed of 550 MHz, and the 1024 MB of GDDR5 memory is set to run at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 Texture Address Units, and 8 ROPs.Compare all of that to the Radeon HD 4850 2GB, which makes use of a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR4 memory is set to run at a frequency of 993 MHz on this specific card. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4850 2GB should theoretically be a bit faster than the GeForce GT 340 1GB overall. (explain)
Texel RateThe Radeon HD 4850 2GB will be quite a bit (about 42%) better at texture filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe Radeon HD 4850 2GB should be a lot (about 127%) more effective at full screen anti-aliasing than the GeForce GT 340 1GB, and capable of handling higher screen 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

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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 number of ROPs by the the core clock speed. 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
