Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 480
IntroThe GeForce GTX 460 1GB has core speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 32 ROPs.
Compare that to the GeForce GTX 480, which uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a frequency of 924 MHz on this particular model. It features 480 SPUs along with 60 TAUs and 48 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 480, in theory, should be a lot faster than the GeForce GTX 460 1GB in general. (explain)
Texel RateThe GeForce GTX 480 is a small bit (about 11%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 480 is superior to the GeForce GTX 460 1GB, 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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
