Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 560
IntroThe GeForce GTX 480 has a GPU core clock speed of 700 MHz, and the 1536 MB of GDDR5 RAM is set to run at 924 MHz through a 384-bit bus. It also features 480 SPUs, 60 TAUs, and 48 ROPs.
Compare those specifications to the GeForce GTX 560, which features a core clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 480 should theoretically be much better than the GeForce GTX 560 overall. (explain)
Texel RateThe GeForce GTX 560 should be a bit (approximately 8%) more effective at texture filtering than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 480 should be much (approximately 30%) faster with regards to AA than the GeForce GTX 560, and also capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once 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, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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.
