It would seem the recently announced Ryzen 7 5800 can be “upgraded” to match its X-series counterpart, simply by enabling PBO. Given its inferior 65W TDP, the non-X SKU runs at lower clocks when using stock settings, but once PBO is enabled, the boosting behaviour appears to be very similar to the Ryzen 7 5800X.
Posting on Weibo, Wolstame (via @9550pro), Lenovo China’s gaming desktop product planning manager, was the first to come to this conclusion. As per the shared screenshots, the Ryzen 7 5800 is an 8C/16T processor featuring a 3.4GHz base clock that boosts up to 4.6GHz and should come with the same 36MB of cache.

After gathering data from both a Ryzen 7 5800 and a Ryzen 7 5800X on a Lenovo 7000P desktop featuring the B550, Wolstame put the results side-by-side for comparison. At stock settings, the Ryzen 7 5800 clocked 100MHz lower in single-core workloads and about the same in multi-core workloads when compared to a stock Ryzen 7 5800X. Once PBO is enabled, the single-core frequency of the Ryzen 7 5800 reaches 4.79GHz, which is about the same as the Ryzen 7 5800X with PBO enabled. The graph shared by Wolstame showed that when running at the same frequency, both processors scored about the same on Cinebench R20 and R23 in both single-core and multi-core workloads.
With such impressive results, the Ryzen 7 5800 would probably be well received in the DIY market, but AMD has already confirmed that it will be OEM-exclusive.
KitGuru says: Let’s hope we see non-X Ryzen 5000 CPUs hit the DIY market before too long.
