Compare any two graphics cards:
GeForce GTX 570 vs Geforce GTX 760
IntroThe GeForce GTX 570 comes with a GPU core speed of 732 MHz, and the 1280 MB of GDDR5 memory runs at 950 MHz through a 320-bit bus. It also is comprised of 480 SPUs, 60 TAUs, and 40 Raster Operation Units.
Compare those specs to the Geforce GTX 760, which features a clock frequency of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1152 SPUs, 96 Texture Address Units, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 760 is 26% faster than the GeForce GTX 570 in general, due to its higher data rate. (explain)
Texel RateThe Geforce GTX 760 will be much (about 114%) faster with regards to texture filtering than the GeForce GTX 570. (explain)
Pixel RateThe Geforce GTX 760 will be a bit (more or less 7%) faster with regards to full screen anti-aliasing than the GeForce GTX 570, and should be able to handle higher resolutions without losing too much performance. (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 MB per second) that can be transferred over 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 RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 maximum number of pixels that 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 ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
