Less Than 6% of Ryzen 9 3900X Processors Can Reach The Advertised Boost Clocks
It is no longer a secret that most of the new AMD Ryzen 3000 series processors can’t reach the advertised boost clocks, but a recent study shows that the Ryzen 9 3900X is the worst of them, with less than 6% of these chips being able to reach the 4.6 GHz frequency.
The famous overclocker and CPU guru, De8auer, held a brief public investigation, asking more than 3,000 people who own a third generation Ryzen to run Cinebench and send him the results to see the max frequencies reached during the test. These results were, according to him, "much weaker than expected."
The third generation Ryzen from AMD was a huge success, however; 7nm processors offer unexpectedly good multi-core performance for the ammount you have to pay for it making it impossible to recommend a similar priced Intel processor.
But it would not be an AMD launch if something wouldn’t go wrong, so it is quite clear that the Boos frequencies that AMD mentioned before launch are far beyond the power offered by the available CPUs at this point.
But the worst result is the Ryzen 9 3900X the 12 cores CPU that has an advertised boost frequency of 4.6Ghz, and AMD strongly argued before launch that the most expensive processor in the 7nm series will be at the same time and best in games due to higher operating frequency.
Meanwhile, the Ryzen 7 3700X with its 65W TDP sees an average of 15% of processors that can reach 4.4Ghz, while 25% of the 95W Ryzen 7 3800X manages to reach 4.5Ghz. But De8auer says the 3800X is a useless processor that no one would recommend. "Useless" might be a bad term, but I would not recommend this processor, realistically speaking.
I have on my personal rig an AMD Ryzen 3600X, and while not even my sample reaches the speed of 4.4Ghz on water cooling, I managed to calm the voltage that reached 1.45v on auto and lower it to 1.2v while all 6 cores of the processor work at the frequency of 4.2Ghz set in the BIOS, so I can say that I got a decent OC without bibbing a lot. Anyway, I'm still convinced that I made the right choice with this processor and I know that Intel couldn't offer me the same level of performance for this money.
