Particularly in regards to both Precision Boost Overdrive and manual overclocking.We chose to go with the limits of the motherboard, noted on the charts below as PBO, and the all-core 4.3 GHz overclock we outlined on the prior page. From a performance and power consumption standpoint, it is more comparable to our all-core 4.3 GHz overclock.
We activated Precision Boost Overdrive, and the processor's power draw only increased marginally to 95W.
Score: 9. Conversely, the all-core overclock consumes much more power but doesn't yield big performance benefits over the PBO settings. But as long as your 12V supply (EPS) readings, motherboard power supply sensor values, and voltage transformer losses plausibly coincide, everything is fine. AMD's Ryzen 3rd Gen. CPUs are completely out in the wild but how does the top-end 8-core model compare to it's lower-powered brother? As such, our PBO+AOC results for the Ryzen 9 3900X and Ryzen 7 3700X are more comparable to the 3800X's all-core overclock.Get instant access to breaking news, in-depth reviews and helpful tips.Thank you for signing up to Tom's Hardware.
The latter uses a heavier distribution of AVX instructions than the former, but both transcoders are great for stressing the processor with a real-world workload.Our power measurements, which we recently migrated towards a more efficiency-focused approach, revealed some interesting tidbits.
Therefore, we're using pure package power to avoid possible influences from our motherboard.
We chose the latter to unlock the full potential of PBO.
AMD Ryzen 7 3800X CPU Review 8-Core Enthusiast Powerhouse. The Ryzen 7 3800X sits on the higher end so it is without a doubt a beast of a CPU for gaming PCs.

That shows that the Ryzen 7 3700X, while slower than the 3800X at stock settings by a larger margin, is competitive in threaded workloads after we tune both processors.

This new feature grants you some control over the maximum attainable boost clocks by allowing you to add up to an extra 200MHz to the maximum boost clock, but it isn't guaranteed that the processor will reach those speeds at all times, or under all conditions. The CPU market is steadily changing colour from Blue to … It's noteworthy that our all-core overclock comes at the expense of the single-core 4.5 GHz boost, which was a relatively rare occurrence during our testing in both stock and PBO trim. These limits vary by motherboard and are defined by the vendor.

Here we can see the 3800X's 4.3 GHz all-core overclock regularly outperform the stock and PBO configurations, but its performance is very similar to the Ryzen 7 3700X with PBO.
This PBO configuration also seems to retain some of those same characteristics, but that doesn't leave much headroom for explosive performance gains.AMD enables two options for PBO: IPM is AMD's default PBO setting, which is activated if you leave the PBO setting to 'Auto' in the Godlike's UEFI.
