Compare any two graphics cards:
GeForce GTX 275 vs GeForce GTX 465
IntroThe GeForce GTX 275 comes with a core clock speed of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also features a 448-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.Compare all that to the GeForce GTX 465, which features a GPU core clock speed of 607 MHz, and 1024 MB of GDDR5 RAM running at 802 MHz through a 256-bit bus. It also features 352 SPUs, 44 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 275 should in theory be much better than the GeForce GTX 465 in general. (explain)
Texel RateThe GeForce GTX 275 should be quite a bit (about 90%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)
Pixel RateThe GeForce GTX 465 is a little bit (approximately 10%) more effective at anti-aliasing than the GeForce GTX 275, and should be capable of handling higher screen 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 (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
