Compare any two graphics cards:
GeForce 9800 GTX+ vs GeForce GT 340
IntroThe GeForce 9800 GTX+ features a GPU core speed of 738 MHz, and the 512 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the GeForce GT 340, which uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this particular card. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GTX+ should be 29% faster than the GeForce GT 340 overall, due to its higher data rate. (explain)
Texel RateThe GeForce 9800 GTX+ should be quite a bit (approximately 168%) better at AF than the GeForce GT 340. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 9800 GTX+ is the winner, and very much so. (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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
