The venerable Neat ReduceNoise has a major update with faster speeds.
And without AI. The good old way.
Initial reactions from other folks that have installed it have been very positive. There are reasonable update offers avaiable if you login.

Did some of my own testing.
The claimed performance gains are very localized. Neat 6 is always faster, but not always 2x faster. But it’s good news for Flame artist.
All tests were done a 2 min clip of 4K DCI video in ProRes 4444. Rendered on the timeline with only Neat plugin applied. And always running the performance analysis to make sure it’s tuned to the hardware.
Test 1:
Mac Studio M1 Ultra, Resolve 19
Neat 5: 2min 15s
Neat 6: 1min 56s - 15% improvement
Test 2:
Puget Systems Linux, 12 core i9 12th Gen, 1x A5000 GPU, Flame 2025.2.2
Neat added as TL-FX in timeline clip.
Neat 5: 9min 43s
Neat 6: 5min 53s - 40% improvement
Test 3:
Puget System Windows, 32 core Xeon, 2x A5000 GPU, Nuke 15.1
Neat 5: 15min 41s
Neat 6: 14min 08s - 10% improvement
Caveat: this time includes decode of ProRes, denoise, and encode of ProRes. Harder to isolate the denoise on it’s own, but also part of real life.
Now you can glee on Flame over Nuke 
but Resolver drivers have your lunch and breakfast.
update
Doing another test on the Mac I noticed that this performance may not be sustained, and the test may need to run longer. Further into the clip it started dropping in FPS as the hardware became too hot.
Initial fps was 27, steady state was around 20, but towards the end dropped to between 6 and 14.
Power consumption: 35W > 199W
CPU Utiliziation > 84%
GPU Utiliziation > 99%
CPU Temp: 139F > 199F
GPU Temp: 136F > 182F
It’s the Mac Trashcan all over. Not designed for sustained max render temp load. Compared to the Puget systems with their big heat sinks and fans, that have consistent render times.

Are the results better?
Haven’t done a detailed comparison, but also generally have no complaints about its quality even before the update. It’s the industry standard, just like DasGrain.
