Compare any two graphics cards:
GeForce GTX 275 vs GeForce GTX 465
IntroThe GeForce GTX 275 has a core clock speed of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also uses a 448-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.Compare those specifications to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 RAM works at a frequency of 802 MHz on this particular card. It features 352 SPUs along with 44 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 275 should in theory perform quite a bit faster than the GeForce GTX 465 in general. (explain)
Texel RateThe GeForce GTX 275 will be quite a bit (about 90%) more effective at texture filtering than the GeForce GTX 465. (explain)
Pixel RateThe GeForce GTX 465 is a bit (approximately 10%) more effective at FSAA than the GeForce GTX 275, and also will be able to handle higher screen resolutions without slowing down too much. (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 data (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
