MSI GTX 1660 Ti Gaming X 6G Review

We of course turned to MSI Afterburner for our overclocking exploits with the Gaming X 1660 Ti. Our best result came with +100MHz to the GPU core, and +875MHz to the Micron GDDR6 memory. I did actually have +145MHz stable during 3DMark testing, but any higher than +100MHz caused Deus Ex: Mankind Divided to insta-crash.

3DMark and games testing

This overclock brought some impressive gains, with an 8% performance bump to our Fire Strike score, and almost another 8FPS when playing Shadow of the Tomb Raider at 1080p. Interestingly, both our games tested with the card overclocked has performance right around RTX 2060 level – 2FPS or so behind, but still very close.

Average clock speed under load

Just to confirm the real-world benefit of our overclock, we saw average clock speed under load increase from 1914MHz to 2003MHz – so we just moved beyond that 2GHz figure which is always good to see.
