Compare any two graphics cards:
GeForce GTX 1060 3GB vs Geforce GTX 770
IntroThe GeForce GTX 1060 3GB has a GPU core clock speed of 1506 MHz, and the 3072 MB of GDDR5 RAM runs at 2000 MHz through a 192-bit bus. It also is made up of 1152 Stream Processors, 72 Texture Address Units, and 48 Raster Operation Units.
Compare all that to the Geforce GTX 770, which uses a 28 nm design. nVidia has set the core frequency at 1046 MHz. The GDDR5 RAM works at a frequency of 1753 MHz on this specific model. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 770 should perform just a bit faster than the GeForce GTX 1060 3GB overall. (explain)
Texel RateThe Geforce GTX 770 is a lot (more or less 23%) better at texture filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB should be quite a bit (about 116%) better at full screen anti-aliasing than the Geforce GTX 770, and 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: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
