Compare any two graphics cards:
GeForce GT 340 vs GeForce GT 430
IntroThe GeForce GT 340 makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this model. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.Compare that to the GeForce GT 430, which features GPU core speed of 700 MHz, and 512 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also features 96 Stream Processors, 16 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 340 should theoretically be much better than the GeForce GT 430 overall. (explain)
Texel RateThe GeForce GT 340 will be quite a bit (more or less 57%) faster with regards to anisotropic filtering than the GeForce GT 430. (explain)
Pixel RateThe GeForce GT 340 should be much (about 57%) more effective at anti-aliasing than the GeForce GT 430, and should be 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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on 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 maximum fill rate.
