The vast majority of AMD Ryzen 3000 processors cannot reach their turbo speeds according to a recent survey. The Ryzen 9 3900X with 12 cores is the worst, where less than 6% of the chips are capable of reaching 4.6GHz (which is the frequency it should reach according to the advertising specifications).
The famous overclocker, Der8auer, has been doing an investigation, surveying more than 3000 Ryzen third-generation CPU owners to do a Cinebench test, to see at what maximum frequency the CPU reaches. And the results are, in his words, "much worse than I expected."
AMD's latest Ryzen 3000 processors have been a great success, manufactured at 7 nm offering unprecedented multinuclear performance and making it almost impossible to recommend Intel chips for a similar price. But it would not be a new release of AMD if there was something that went terribly wrong, and it is increasingly clear that the turbo speeds announced by AMD are beyond the capabilities of the vast majority of CPUs that have been sold so far.
But the truth is, the survey is not very fair, and Der8auer strives in his video to explain the possible difficulties of creating these statistics. Users would have to have the energy management of AMD, a particular BIOS version, and even a motherboard model and, a cooling system that allows to offer a suitable temperature for that speed.
But still it is not a good read. Obviously, the worst result is for the AMD Ryzen 9 3900X, 12-core with a 4.6GHz turbo and AMD making a lot of noise before launching on the fact that its most powerful and most expensive 7 nm processor was also the best CPU for games for having higher speeds.
Of the 685 results with this CPU, Der8auer concludes that only 6% of those processors were capable of delivering a maximum speed of 4.6GHz. According to Der8auer some reach 4.55 GHz, for example, something that can only hold for a second, and then slow down.
It's worse than I thought – RYZEN 3000 Boost Survey
The rest of the CPUs are left with these percentages: In the Ryzen 5 3600X 10% can reach its maximum speed, and the 3600 has a 50% chance of reaching its maximum speed.
In the Ryzen 7 3700X, around 15% can reach its maximum speed and around 25% of the Ryzen 7 3800X reach 4.5GHz. Although Der8auer calls the 3800X a “useless CPU that I would not recommend buying”. Useless is not the word we would use, but we don't recommend it either.
Basically, this seems to show that 7 nm Zen 2 silicon is currently not able to give what it says. Der8auer also talks about the Aorus X570 motherboards that are largely the majority in the survey results.
