The NVIDIA GeForce GTX 1660 Review, Feat. EVGA XC GAMING: Turing Stakes Its Claim at $219by Ryan Smith & Nate Oh on March 14, 2019 9:01 AM EST
Last, but not least, we'll take a look at overclocking. While NVIDIA does support overclocking, they have limited actual overvolting, and instead providing the ability to unlock 1-2 more boost bins and associated voltages. Either way, Maxwell 2 and Pascal certainly have much to thank for high clockspeeds; for Maxwell 2, it was a combination of high efficiency and ample overclocking headroom, while Pascal took advantage of the FinFET process to ramp up the clocks to new heights.
A total of four different overclocks were tested via EVGA's Precision X1; unfortunately, we were not able to get the auto OC scanning functionality to fully work. First was a baseline, consisting of 100% overvoltage and max temperature limits; power limit is already set to a soft cap of 130W at stock. The second was overclocking the GDDR5 memory by 1Gbps. The third was overclocking the GPU by +100MHz; in practice, observed clocks were in the mid 1900MHz. Lastly, all previous adjustments were combined for an overall overclock.
|GeForce GTX 1660 Overclocking|
|Baseline||Memory OC||GPU OC||All OC|
|Memory Clock||8Gbps||9Gbps (+250MHz)||8Gbps||9Gbps (+250MHz)|
Naturally, these results cannot be taken as representative of all GTX 1660 cards, but results here can offer some insight.
