Compare any two graphics cards:
GeForce GT 320 vs GeForce GT 340
IntroThe GeForce GT 320 uses a 40 nm design. nVidia has set the core speed at 540 MHz. The GDDR3 memory is set to run at a frequency of 790 MHz on this particular model. It features 72 SPUs as well as 24 Texture Address Units and 8 ROPs.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 frequency 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 should perform quite a bit faster than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GT 340 should be a lot (about 36%) faster with regards to texture filtering than the GeForce GT 320. (explain)
Pixel RateThe GeForce GT 340 should be just a bit (approximately 2%) faster with regards to AA than the GeForce GT 320, and also should be able to handle higher screen resolutions better. (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 data (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 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 maximum fill rate.
