Compare any two graphics cards:
GeForce GT 340 1GB vs GeForce GTX 590
IntroThe GeForce GT 340 1GB has core speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.Compare those specs to the GeForce GTX 590, which comes with core speeds of 607 MHz on the GPU, and 855 MHz on the 1536 MB of GDDR5 RAM. It features 512 SPUs along with 64 Texture Address Units and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 590 should theoretically perform much faster than the GeForce GT 340 1GB in general. (explain)
Texel RateThe GeForce GTX 590 will be a lot (about 341%) more effective at AF than the GeForce GT 340 1GB. (explain)
Pixel RateThe GeForce GTX 590 is a lot (more or less 1224%) more effective at anti-aliasing than the GeForce GT 340 1GB, and should be able to handle higher resolutions without losing too much performance. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core 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 applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 get to the maximum fill rate.
