Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 has a GPU core speed of 915 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1500 MHz through a 256-bit bus. It also is made up of 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.
Compare that to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this particular card. It features 1152 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
As far as performance goes, the Geforce GTX 760 should in theory be a little bit superior to the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 670 will be just a bit (approximately 9%) better at AF than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 760 is just a bit (approximately 7%) faster with regards to anti-aliasing than the Geforce GTX 670, and able to handle higher screen resolutions better. (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 largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core 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 output 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.
