Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GT 340
IntroThe GeForce 9800 GT 512MB has a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also features 112 SPUs, 56 Texture Address Units, and 16 ROPs.Compare all that to the GeForce GT 340, which has GPU core speed of 550 MHz, and 512 MB of GDDR5 RAM set to run at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GT 512MB, in theory, should be just a bit faster than the GeForce GT 340 overall. (explain)
Texel RateThe GeForce 9800 GT 512MB should be much (approximately 91%) faster with regards to texture filtering than the GeForce GT 340. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9800 GT 512MB is superior to the GeForce GT 340, by far. (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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core 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 fill rate also depends on quite a few 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.
