Power, Temperature, & Noise

Finally, let's talk about power, temperature, and noise. At a high level, the Titan V should not be substantially different from other high-end NVIDIA cards. It has the same 250W TDP, and the cooler is nearly identical to NVIDIA’s other vapor chamber cooler designs. In short, NVIDIA has carved out a specific niche on power consumption that the Titan V should fall nicely into.

Unfortunately, no utilities seem to be reporting voltage or HBM temperature of Titan V at this time. These would be particularly of interest considering that Volta is fabbed on TSMC's bespoke 12FFN as opposed to 16nm FinFET. This also marks the first time NVIDIA has implemented HBM2 in gaming use-cases, where HBM temperatures or voltages could be elucidating.

Interestingly, LuxMark only brings Titan V to 1355MHz instead of its maximum boost clock, a behavior that differs from every other card we've benched in recent memory. Other compute and gaming tasks do bring the clocks higher, with a reported peak of 1785MHz.

The other takeaway is that Titan V is consistently outclocked by Titan Xp. In terms of gaming, Volta's performance gains do not seem to be coming from clockspeed improvements, unlike the bulk of Pascal's performance improvement over Maxwell.

Meanwhile it's worth noting that the HBM2 memory on the Titan V has only one observed clock state: 850MHz. This never deviates, even during FurMark as well as extended compute or gameplay. For the other consumer/prosumer graphics cards with HBM2, AMD's Vega cards downclock HBM2 in high temperature situations like FurMark, and also features a low-power 167MHz idle state.

Idle Power Consumption

Measuring power from the wall, Titan V's high idle and lower load readings jump out.

Meanwhile under load, the Titan V's power consumption at the wall is slightly but consistently lower than the Titan Xp's. Again despite the fact that both cards have the same TDPs, and NVIDIA's figures tend to be pretty consistent here since Maxwell implemented better power management.

Idle GPU Temperature

During the course of benchmarking, GPU-Z reported a significant amount of Titan V thermal throttling, and that continued in Battlefield 1, where it oscillated between being capped out by GPU underutilization and temperature. And in FurMark, the Titan V was consistently temperature-limited.

Without HBM2 voltages, it is hard to say if the constant 850MHz clocks are related to Titan V's higher idle system draw. 815mm2 is quite large, but then again elements like Volta's tensor cores are not being utilized in gaming. In Battlefield 1, system power draw is actually lower than Titan Xp but GPU Z would suggest that thermal limits are the cause. Typically what we've seen with other NVIDIA 250W TDP cards is that they hit their TDP limits more often than they hit their temperature limits. So this is an unusual development.

Featuring an improved cooler, Titan V essentially manages the same noise metrics as its Titan siblings.

    Bah but this is last week's Titan, aren't they launching a new one this week? Reply

    Titan A, next week Titan G, next 2 weeks Titan I, next month Titan N, and lastly Titan AS Reply

    Don't forget the dual Volta Titan ZZ Reply

    ...in case anyone wondered why they never released Pascal as Titan P. I guess Nvidia knows their market too well for that. Reply

    Well, they'll presumably release the GV102 in some more affordable flavor of Titan. Titan V0?

    And maybe they'll eventually release a GV100 in a PCIe card with all four HBM2 stacks... although that'll probably receive Quadro branding & price point, like the Quadro GP100.

    So, after Titan Xp and Titan V(ista), next should be Titan 7. That's a definite buy, but I'd skip Titan 8. Maybe go for Titan 8.1, or just hold out for Titan 10. Reply

    OK, while I agree that nobody should buy a Titan V for gaming you say: "Already after Battlefield 1 (DX11) and Ashes (DX12), we can see that Titan V is not a monster gaming card, though it still is faster than Titan Xp. "

    Uh... yeah that's wrong. Anything that's faster than a Titan XP *is* a monster gaming card by definition. It's just not a very good purchase for $3000 since it's not really targeted towards gaming.

    I agree with this. Cost aside - it's the best gaming card on the market. Unless NVIDIA launches the 1180/2080/whatever80 soon, this card will be in Terry Crews' Old Spice rig by the end of the month.

    P-P-P-POWWWWERRRRRRRRRR!

    "Uh... yeah that's wrong. Anything that's faster than a Titan XP *is* a monster gaming card by definition."

    The big issue right now is that it's not consistently faster, especially at the 99th percentile Or for that matter, not as bug-free as it needs to be.

    I'm going to be surprised if it doesn't get better with later drivers. But for the moment, even if you throw out the price, it's kind of janky in games.
