Compare any two graphics cards:
GeForce GT 340 1GB vs GeForce GTX 570
IntroThe GeForce GT 340 1GB uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 memory works at a frequency of 850 MHz on this particular card. It features 96 SPUs as well as 32 TAUs and 8 ROPs.Compare those specifications to the GeForce GTX 570, which comes with clock speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 RAM. It features 480 SPUs as well as 60 Texture Address Units and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 570 should in theory be quite a bit superior to the GeForce GT 340 1GB overall. (explain)
Texel RateThe GeForce GTX 570 is much (more or less 150%) faster with regards to anisotropic filtering than the GeForce GT 340 1GB. (explain)
Pixel RateThe GeForce GTX 570 should be much (about 565%) better at anti-aliasing than the GeForce GT 340 1GB, and also should be capable of handling higher screen 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 data (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core clock 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 in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
