Compare any two graphics cards:
GeForce GT 320 vs GeForce GTS 250 1GB
IntroThe GeForce GT 320 features a GPU core clock speed of 540 MHz, and the 1024 MB of GDDR3 RAM is set to run at 790 MHz through a 128-bit bus. It also is comprised of 72 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the GeForce GTS 250 1GB, which makes use of a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 RAM is set to run at a frequency of 1100 MHz on this particular card. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 250 1GB should be quite a bit faster than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GTS 250 1GB should be a lot (approximately 264%) more effective at AF than the GeForce GT 320. (explain)
Pixel RateThe GeForce GTS 250 1GB is much (about 173%) faster with regards to anti-aliasing than the GeForce GT 320, and will be capable of handling higher resolutions more effectively. (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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
