You made me look into this and what I found... Let's just say I'm turning this shit off on my 3700x
Charts at the link.
It's crazy how in some cases, NO PBO is actually better (particularly in gaming environments). Fuck that. Ain't worth it. pbo actually performed worse in 7zip decompression. It only had a = or greater than ~1% performance increase with benchmarks like jetstream tho.Conclusion: There is no reason to use Precision Boost Overdrive and AutoOC
Our conclusion is that neither "Precision Boost Overdrive" nor PBO + AutoOC are worth enabling if you are using an AMD Ryzen 7 3700X:
- The performance gains in benchmarks are mixed. Although you can get a one percent speed boost, more often than not, you're getting less performance
- In some games you get a few more frames per second, but in others you get fewer frames per second
- Both the processor's temperature and its power consumption increase, because of the higher voltages used
Power draw was significantly higher and thus temperatures were also higher:
To get an idea of how much the temperature of the processor is affected by enabling "Precision Boost Overdrive," we did some logging using HWiNFO while running Prime95. While running at factory settings, the processor did not get hotter than 89 degrees Celsius. However, with PBO and PBO + AutoOC enabled, the processor reached 95 degrees Celsius, which is its maximum official temperature.
Yea fuck that.
