NVIDIA TITAN V Review: Volta Compute, Mining, And Gaming Performance Explored
NVIDIA TITAN V: Overclocking, Power, Heat, And Noise
We also spent a little time overclocking the NVIDIA TITAN V to see what kind of additional performance it had left under its hood. To overclock the card we used the latest version of EVGA's Precision app, which has proper support for the GV100, and kept things super simple.
We've only had the card in hand for a very short time, and wanted to get this article posted as soon as possible, so all we did to overclock the TITAN V was crank up the power and temperature targets to see how it affected the GPU frequency.
Right out of the box, the TITAN V will actually hit its default power and temperature targets while under a sustained load, which causes the card to quickly bounce in and out of boost states. Its default boost clock is 1,455MHz, so simply increasing the power and temperature targets unlocked quite of a bit of frequency. We saw a peak GPU clock of 1,815MHz, which is quite a significant jump without touching the offset frequency. Even with additional cooling and frequency manipulation, however, we suspect the TITAN V will be power limited -- as you can see, we hit the power limit even with the target maxed out. We have to do some more experimenting here.

Before bringing this article to a close, we'd like to cover a couple of final data points for power consumption and acoustics. Throughout all of our benchmarking and testing, we monitored noise output and tracked how much power our test system was consuming using a power meter. Our goal was to give you an idea of how much power each configuration used while idle and also while under a heavy gaming workload. Please keep in mind that we were testing total system power consumption at the outlet here, not the power being drawn by the graphics cards alone. It's a relative measurement that gives you a decent view of how much additional power draw a graphics card is placing on a system.
The TITAN V consumed more power than all of the other cards we tested, under both idle and load conditions. Idle power was roughly 11 watts higher than a TITAN Xp and peak, load power was about 23 watts higher and topped the charts. In terms of efficiency, however, the TITAN V is a clear winner. It was nearly twice as fast a Radeon RX Vega 64 in many gaming workloads and many times faster in some compute workloads, while consuming only a bit more power.
We also monitored system power with the TITAN V installed under a variety of other conditions. The overclocked gaming workload resulted in the highest power consumption, but all of the compute workloads resulted in significantly lower power utilization.
We should also mention that noise on the TITAN V is a non-issue. Even under a sustained load, the card sounds and behaves much like a TITAN Xp or GTX 1080 Ti, which is to say its fan does spin up and become audible outside of a chassis, but it is not loud by any means. GPU temperatures on the TITAN V aren't really a concern either, but the card will hit its 82 degree temperature target under load with the default fan curve.
