Compare any two graphics cards:
GeForce GT 430 vs GeForce GTS 250 1GB
IntroThe GeForce GT 430 comes with a core clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.Compare all that to the GeForce GTS 250 1GB, which features a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also makes use of a 256-bit bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 250 1GB should theoretically be a lot better than the GeForce GT 430 in general. (explain)
Texel RateThe GeForce GTS 250 1GB will be a lot (more or less 322%) faster with regards to texture filtering than the GeForce GT 430. (explain)
Pixel RateThe GeForce GTS 250 1GB will be a lot (approximately 322%) faster with regards to FSAA than the GeForce GT 430, and able to handle higher screen resolutions without losing too much performance. (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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to 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 bandwidth is, the lower the potential to get to the maximum fill rate.
