Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 has a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 memory is set to run at 1500 MHz through a 256-bit bus. It also is comprised of 1344 Stream Processors, 112 Texture Address Units, and 32 Raster Operation Units.
Compare those specs to the Geforce GTX 760, which uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 memory works at a speed of 1502 MHz on this model. It features 1152 SPUs along with 96 TAUs and 32 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
As far as performance goes, the Geforce GTX 760 should in theory be just a bit superior to the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 670 will be a bit (approximately 9%) more effective at anisotropic filtering than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 760 is a bit (more or less 7%) faster with regards to anti-aliasing than the Geforce GTX 670, and also will be 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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses 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 high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
