Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 460 (OEM)
IntroThe GeForce GTX 260 features core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 192 SPUs along with 64 TAUs and 28 ROPs.
Compare those specifications to the GeForce GTX 460 (OEM), which makes use of a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 RAM runs at a speed of 850 MHz on this specific card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 260 should in theory be a bit superior to the GeForce GTX 460 (OEM) in general. (explain)
Texel RateThe GeForce GTX 260 should be just a bit (approximately 1%) more effective at anisotropic filtering than the GeForce GTX 460 (OEM). (explain)
Pixel RateThe GeForce GTX 460 (OEM) will be a lot (more or less 29%) better at anti-aliasing than the GeForce GTX 260, and also 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.
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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card 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 applied per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
