Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs GeForce GTX 295
IntroThe GeForce GTX 260 216SP 55 nm comes with a clock frequency of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also uses a 448-bit memory bus, and makes use of a 55 nm design. It features 216 SPUs, 72 Texture Address Units, and 28 ROPs.Compare all that to the GeForce GTX 295, which comes with GPU clock speed of 576 MHz, and 896 MB of GDDR3 RAM running at 999 MHz through a 448-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 28 ROPs.

GeForce GTX 295 wins(Based entirely on the benchmarks listed above)When combining all game benchmark scores on this page together, the GeForce GTX 295 wins overall, by 119 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 295 is 100% quicker than the GeForce GTX 260 216SP 55 nm overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 295 will be a lot (about 122%) better at AF than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateThe GeForce GTX 295 should be a lot (about 100%) faster with regards to full screen anti-aliasing than the GeForce GTX 260 216SP 55 nm, and capable of handling higher screen resolutions while still performing well. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Specifications
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
