Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 460 (OEM)
IntroThe GeForce GTX 260 comes with a clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit memory bus, and makes use of a 65 nm design. It features 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.Compare all that to the GeForce GTX 460 (OEM), which has GPU core speed of 650 MHz, and 1024 MB of GDDR5 RAM set to run at 850 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 260 should be a bit faster than the GeForce GTX 460 (OEM) overall. (explain)
Texel RateThe GeForce GTX 260 should be just a bit (approximately 1%) more effective at texture filtering than the GeForce GTX 460 (OEM). (explain)
Pixel RateThe GeForce GTX 460 (OEM) is much (more or less 29%) faster with regards to full screen anti-aliasing than the GeForce GTX 260, and should be able to handle higher resolutions better. (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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page.

Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
