Compare any two graphics cards:
GeForce GTX 570 vs Geforce GTX 760
IntroThe GeForce GTX 570 has a core clock speed of 732 MHz and a GDDR5 memory speed of 950 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.
Compare those specs to the Geforce GTX 760, which uses a 28 nm design. nVidia has clocked the core frequency at 980 MHz. The GDDR5 memory works at a speed of 1502 MHz on this specific model. It features 1152 SPUs as well as 96 TAUs and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 760, in theory, should perform quite a bit faster than the GeForce GTX 570 in general. (explain)
Texel RateThe Geforce GTX 760 should be a lot (more or less 114%) more effective at AF than the GeForce GTX 570. (explain)
Pixel RateThe Geforce GTX 760 will be a small bit (about 7%) more effective at full screen anti-aliasing than the GeForce GTX 570, and also capable of handling higher screen 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: Bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, 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 maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 ability to get to the max fill rate.
