Ryzen 9 3900X And Ryzen 7 3700X: Zen 2 Arrives With A Bang
The Zen 2-based AMD Ryzen 3000 series is easily one of the most anticipated product launches in the PC space in recent memory. AMD has essentially promised to address virtually all of the perceived shortcomings of the original Zen-based Ryzen processors, with the Ryzen 3000 series, while continuing to aggressively challenge Intel on multiple fronts – performance, power, price, you name it.

Our Verdict
The AMD Ryzen 9 3900X is the best mainstream processor on the market right now. With multi-threaded performance that destroys everything in its path and the inclusion of PCIe 4.0, you can’t find a better
processor without stepping up to the HEDT market.

Only 5.6% Of Ryzen 9 3900X CPUs Reach Advertised Boost Speeds: Survey
September 2, 2019
https://fossbytes.com/only-5-6-of-ryzen-9-3900x-cpus-reach-advertised-boost-speeds-survey/

However, a recent survey by hardware reviewer De8auer has revealed that a majority of AMD’s Ryzen 9 3900X fail to reach the advertised boost speeds.

It was found that only 5.6% of CPUs reached the advertised boost speed of 4.6 GHz. Other SKUs from the Ryzen series performed well in the survey except 3900X. AMD recently confirmed that only one core on any CPU reaches the rated boost speed.
On the contrary, the survey shows that most users aren’t getting the advertised boost clock on any of the cores.

“Why did AMD feel that it is necessary to advertise the boost or give the people false expectations and false hope for something that they cannot get?” – he questioned AMD.
While the numbers give an idea of situation many users are facing, it still can’t be generalized. For instance, De8auer notes that users who didn’t get satisfactory results are more likely to report the results than one who did, and this could affect the overall results.

AMD Promises to Fix 3rd-gen Ryzen Speed Boost Bug

https://www.cdrinfo.com/d7/content/amd-promises-fix-3rd-gen-ryzen-speed-boost-bug

AMD on Tuesday promised that a BIOS update will address reports that its 3rd-generation Ryzen processors aren’t able to hit advertised boost speeds under all conditions.

“While processor boost frequency is dependent on many variables including workload system design, and cooling solution, we have closely reviewed the feedback from our customers and have identified an issue in our firmware that reduces boost frequency in some situations,” AMD said via Twitter, The statement says that the BIOS update will be released on September 10 via AMD’s motherboard partners.
AMD’s statement also says the BIOS update will provide “additional boost performance optimizations,” in addition to addressing the boost issue.

AMD releases BIOS update to fix Ryzen boost performance
September 10, 2019
https://venturebeat.com/2019/09/10/amd-ryzen-boost-bios-update/

AMD claims it has a fix for the Ryzen boost that will roll out soon in a BIOS update. Since launching in July, Ryzen owners have discovered that many CPUs don’t reach their max boost clock speed. But the processor company says it has eliminated this problem in many circumstances.

“Our analysis indicates that the processor boost algorithm was affected by an issue that could cause target frequencies to be lower than expected,” reads an AMD press release.
“This has been resolved. We’ve also been exploring other opportunities to optimize performance, which can further enhance the frequency. These changes are now being implemented in flashable BIOSes from our motherboard partners.”
When does AMD’s boost clock fix BIOS update go live, and how can I get it?
AMD estimates that it’s going to take about three weeks for its patch to reach you and me. The update is finished, and the company handed it over to motherboard manufacturers. But now those hardware partners new to certify the update and run it through their own prelaunch testing.
