Compare any two graphics cards:
GeForce GT 320 vs GeForce GT 340
IntroThe GeForce GT 320 makes use of a 40 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 RAM is set to run at a speed of 790 MHz on this particular model. It features 72 SPUs along with 24 TAUs and 8 Rasterization Operator Units.Compare those specs to the GeForce GT 340, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory is set to run at a speed of 850 MHz on this model. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 340 is 115% faster than the GeForce GT 320 overall, due to its greater data rate. (explain)
Texel RateThe GeForce GT 340 is a lot (approximately 36%) better at AF than the GeForce GT 320. (explain)
Pixel RateThe GeForce GT 340 should be a little bit (approximately 2%) faster with regards to anti-aliasing than the GeForce GT 320, and also will be able to handle 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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 maximum number 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 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
