Nvidia octane render
We ran the same GPU on the Classroom project as a sanity check, and it does use more power there, but still not as much as we’d expect (260W) for a top-end Vega. We’ve seen this same behavior in previous looks, where rendering uses far less power than gaming, although the delta between them is far more pronounced today.
While its performance makes the Radeon VII not as relevant today as it was at launch, we feel compelled to point out that we have no idea why its power consumption is so modest in comparison to the rest of the GPUs here. With either metric, NVIDIA’s top-end RTX 3080 Ti and RTX 3090 prove to be the power-hungriest in our lineup, but they also happen to deliver the best performance, so it’s hard to complain. In every single case (aside from 1080 Ti), gaming will draw far more power than rendering. The reason we power test both rendering and gaming workloads is probably made obvious by the big deltas seen above.

Power is recorded with a Kill-A-Watt meter, measuring full system power draw. Both workloads are run for five minutes, with safe peak values recorded (eg: ignoring spikes that happen for a split second because Windows decides to do something). On the rendering side, we run the Still Life project released alongside Blender 2.93 for gaming, we use 3DMark’s Fire Strike 4K stress-test. To test this collection of GPUs for power and temperatures, we use both rendering and gaming workloads. Truly odd, and annoying, since it leads us to spend time retesting! Power Consumption Last summer, we saw the same thing with the RTX 2070 SUPER performing the same (or better) than the RTX 2080 SUPER. But no one wants to pay more for less performance in their tool of choice. If the 3070 Ti had a bigger frame buffer, it’d be a no-brainer. It could be that future KeyShot versions will fix those flip-flopped results, but as it stands today, we’d suggest the RTX 3070 over the 3070 Ti if KeyShot is your primary design tool, since it does prove faster at this current point in time. Similarly, with the Circuit Board scene, the 3080 Ti somehow fell behind the 3080 (yes, we retested that, too.) We can’t explain why these anomalies happen, but we’re well over being surprised when they creep up. In both projects, the RTX 3070 Ti fell behind the performance of the RTX 3070, which is yet another thing that forced us to reinstall both GPUs in order to sanity check (surprise: the results held). There are a couple of odd results in both of the graphs above worth highlighting.

Like Arnold, KeyShot will automatically take advantage of RT acceleration if a GPU offers it, and also like Arnold, KeyShot highlights that it’s time to upgrade your GTX 1080 Ti.
