We've heard a lot about the GTX 1660 SUPER over the last few weeks, and today the new graphics card from Nvidia has been officially announced. For launch we have two partner card reviews, but this is focused on the Gigabyte GTX 1660 SUPER Gaming OC 6G – a triple-fan, factory overclocked card that promises low temperatures and high frame rates. Is it – and 1660 SUPER as a whole – any good?

If you've been living under a rock for the last few weeks, it is very easy to summarise what Nvidia has done with the GTX 1660 SUPER – take a vanilla GTX 1660, swap out the slower GDDR5 memory for improved GDDR6 modules, and you have a GTX 1660 SUPER.

That means the TU116 GPU at the heart of the GTX 1660 is entirely unchanged – it's the same Turing architecture, it still sports 22 SMs and 1408 CUDA Cores, and there's still no RT or Tensor cores as per the RTX 20-series cards. It's purely the upgrade to G6 memory from G5 which makes this a ‘SUPER' card.

I'd also like to just clarify where the 1660 SUPER sits in Nvidia's product stack, as it is now a very busy line-up. Put simply, GTX 1660 SUPER, with a £209.99 MSRP, slots in between GTX 1660 (£199) and GTX 1660 Ti (£259). Neither the GTX 1660 or GTX 1660 Ti are being phased out according to Nvidia, but while there will be no official price cut to the GTX 1660, Nvidia does expect prices to fall naturally as a result of 1660 SUPER entering the market.

We already mentioned how the only core change to the GTX 1660 is the upgraded 14Gbps GDDR6 memory, and that improves total memory bandwidth from 192.1GB/s to 336 GB/s.

Additionally, while there is no reference card per se, Nvidia did release ‘reference spec', so we can see that the Gigabyte Gaming OC 6G model for review here has been factory overclocked by 75MHz, up to 1860MHz boost.

Lastly, with what can only be a consequence of the change in memory, it is also worth noting that 1660 SUPER has a Total Graphics Power (TGP) rating of 125W, a 5W increase over the vanilla 1660.
