I started testing off with the usual suspects in synthetic benchmarks 3DMark and Unigine’s Superposition. For 3DMark I ran all three Fire Strike tests which are all DX11 based and then I did the newer Time Spy DX12 focused tests as well. It is important to keep in mind that comparing the Gigabyte GTX 1660 Ti OC to the other GTX 1660 Ti’s that I have tested. All three were overclocked over the 1770 MHz of a “stock” GTX 1660 Ti, not that I have seen any at that speed. The Gigabyte card though comes in with an 1800 MHz boost clock where the MSI was 1830 MHz and the EVGA was a high end 1660 Ti with its 1860 MHz clock speed. So with that in mind, I wasn’t expected the Gigabyte to outperform the other two GTX 1660 Ti’s. The drop in Fire Strike in the first two tests, however, was more than I anticipated with the RX 590 even slipping up over it in the Extreme setting.
Like Nvidia’s other Turning based cards the Gigabyte GTX 1660 Ti OC did pull ahead in the DX12 based Time Spy tests. It was again still a lot farther behind the other 1660 Ti’s than expected, but still up over the GTX 1070.
Then in Unigine Superposition, we saw more of the same. A drop down from the two higher overclocked cards, but worlds better than the RX590. In this test however the GTX 1070 was still faster, being a DX11 based test this is to be expected.
