Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 760
IntroThe Geforce GTX 670 comes with a GPU core clock speed of 915 MHz, and the 2048 MB of GDDR5 RAM runs at 1500 MHz through a 256-bit bus. It also is made up of 1344 SPUs, 112 Texture Address Units, and 32 ROPs.
Compare those specs to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has clocked the core speed at 980 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this card. It features 1152 SPUs along with 96 TAUs and 32 Rasterization Operator Units.
(No game benchmarks for this combination yet.)
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Theoretically, the Geforce GTX 760 should perform a little bit faster than the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 670 will be a bit (more or less 9%) faster with regards to texture filtering than the Geforce GTX 760. (explain)
Pixel RateThe Geforce GTX 760 is just a bit (about 7%) faster with regards to anti-aliasing than the Geforce GTX 670, and also should be capable of handling higher resolutions while still performing well. (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 information (counted in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 are processed in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 that the graphics chip 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 amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
