Compare any two graphics cards:
GeForce GTX 1060 vs GeForce GTX 1060 3GB
IntroThe GeForce GTX 1060 comes with a GPU clock speed of 1506 MHz, and the 6144 MB of GDDR5 memory runs at 2000 MHz through a 192-bit bus. It also is comprised of 1280 SPUs, 80 Texture Address Units, and 48 ROPs.
Compare those specs to the GeForce GTX 1060 3GB, which features a core clock speed of 1506 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 192-bit memory bus, and uses a 16 nm design. It features 1152 SPUs, 72 TAUs, and 48 Raster Operation Units.
BenchmarksThese are real-world performance benchmarks that were submitted by Hardware Compare users. The scores seen here are the average of all benchmarks submitted for each respective test and hardware.
Zcash Mining Hash Rate
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have exactly the same bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe GeForce GTX 1060 will be a little bit (approximately 11%) more effective at texture filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateBoth cards have the exact same pixel rate, so in theory they should perform equally good at at FSAA, and be capable of handling the same resolutions. (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.
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in 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 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
