Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GT 340
IntroThe GeForce 9800 GT 512MB features a core clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 65/55 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare that to the GeForce GT 340, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this card. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 9800 GT 512MB should in theory be a small bit better than the GeForce GT 340 overall. (explain)
Texel RateThe GeForce 9800 GT 512MB should be much (about 91%) faster with regards to texture filtering than the GeForce GT 340. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 9800 GT 512MB is a better choice, 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: Bandwidth is the max 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 card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 are applied in one second. This figure 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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 max fill rate.
