Compare any two graphics cards:
GeForce GT 230 vs GeForce GT 340 1GB
IntroThe GeForce GT 230 uses a 40 nm design. nVidia has clocked the core speed at 550 MHz. The DDR3 memory is set to run at a speed of 800 MHz on this particular model. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.Compare all of that to the GeForce GT 340 1GB, which makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this particular card. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 340 1GB should be 42% quicker than the GeForce GT 230 in general, due to its higher data rate. (explain)
Texel RateThe GeForce GT 340 1GB should be much (approximately 100%) faster with regards to anisotropic filtering than the GeForce GT 230. (explain)
Pixel RateBoth cards have exactly the same pixel rate, so theoretically they should be equally good at at AA, and be capable of handling the same screen 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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at 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 graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
