Willow R. Used for: 3–6 months
Cons
Needs a serious cooler, none supplied
Comment
Brilliant all rounder. Buy a big cooler though
Grace F. Used for: More than a year
Pros
Twelve cores at a sensible price
Cons
Stock power settings chase the last few percent
Comment
Solid service throughout. Wish I had known sooner how much cooler the eco mode runs for so little loss.
Grace R. Used for: 6–12 months
Pros
Twelve cores means a VM can have four and I never notice
Comment
This has been the right chip for a machine that has to do two jobs. Daytime it runs virtual machines and a database locally, and twelve cores means I can give four to a VM and never notice. Evenings it plays whatever I fancy at 1440p and the graphics card is always the limit, not this. The only reason it is not five stars is that AMD ship it configured to run hot for a couple of percent. Set a modest curve offset and it is thirteen degrees cooler for nothing measurable. Eleven months of running it that way and nothing has misbehaved.
Oscar K. Used for: Less than a month
Pros
Genuinely fast once you get it settled
Cons
Boost spikes make the fan curve surge constantly
Comment
I am not convinced yet, which is not what I expected to be writing about a Ryzen 9. The raw performance is there, no argument. Twelve cores handle anything I throw at them and the single core speed is high enough that ordinary desktop work feels instant. The problem is the boost behaviour on my board. It spikes to 95 within a second of any load starting, then throttles back, and the fan curve chases it up and down constantly so the machine is never quietly idle or steadily loud, just surging. Manually capping the boost calmed it, but I should not have to do that on a chip at this price. Three stars until I get it settled. Two weeks of fiddling with it and I am not there yet.

Pros
Twelve cores cut my full rebuild from eleven minutes to seven
Comment
This lives in a machine that spends its working hours compiling and its evenings gaming, and my verdict is that twelve cores is the right number for that mix, and fifteen months in the machine has not changed my mind. On the work side it is a big step up from the eight core part it replaced. Full rebuilds that took eleven minutes now take seven, and the machine stays responsive while it happens, which the old chip never managed. Power draw under that load is around 180W which my 280 AIO handles without getting loud. Gaming is where the four stars come from. It is perfectly good, but it is not an X3D chip and in the two simulation titles I play most a friend's cheaper 7800X3D beats it on the lows despite having fewer cores. If your machine is mostly for games, buy that instead and spend the difference elsewhere. For mixed use, this is the better buy.
