Compare any two graphics cards:
GeForce GTX 570 vs Geforce GTX 670
IntroThe GeForce GTX 570 comes with a core clock speed of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also makes use of a 320-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 TAUs, and 40 Raster Operation Units.
Compare that to the Geforce GTX 670, which uses a 28 nm design. nVidia has clocked the core speed at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this card. It features 1344 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 670 should perform a lot faster than the GeForce GTX 570 overall. (explain)
Texel RateThe Geforce GTX 670 is a lot (about 133%) faster with regards to texture filtering than the GeForce GTX 570. (explain)
Pixel RateBoth cards have the exact same pixel rate, so in theory they should be equally good at at anti-aliasing, and be able to handle the same resolutions. (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. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core clock 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 in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
