Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 460 (OEM)
IntroThe GeForce GTX 260 makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory works at a speed of 999 MHz on this specific card. It features 192 SPUs as well as 64 Texture Address Units and 28 ROPs.
Compare those specifications to the GeForce GTX 460 (OEM), which comes with a clock frequency of 650 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 260 should be a bit faster than the GeForce GTX 460 (OEM) overall. (explain)
Texel RateThe GeForce GTX 260 is a bit (about 1%) better at anisotropic filtering than the GeForce GTX 460 (OEM). (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 460 (OEM) is superior to the GeForce GTX 260, by far. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
