Compare any two graphics cards:
GeForce GT 340 vs GeForce GT 340 1GB
IntroThe GeForce GT 340 features a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 ROPs.Compare those specs to the GeForce GT 340 1GB, which has GPU core speed of 550 MHz, and 1024 MB of GDDR5 RAM running at 850 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should have the same performance. (explain)
Texel RateBoth cards have the exact same texel fill rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)Pixel RateBoth cards have exactly the same pixel fill rate, so in theory they should be equally good at at FSAA, and be able to handle the same resolutions. (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 data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 potential to get to the maximum fill rate.
