AMD Ryzen XFR Frequencies Revealed
AMD's upcoming Ryzen processors are "unlocked," in that they feature unlocked base-clock multipliers that let you easily overclock them; yet a few of its variants feature a brand extension "X." As our older article details, the "X" refers to availability of the XFR (extended frequency range) feature. Think of it as a second stage boost that rewards good CPU cooling with higher CPU clocks set automatically. The Ryzen R7-1800X, R7-1700X, R5-1600X, R5-1400X, and R3-1200X feature this.
The R7-1800X features clock speeds of 3.60 GHz, with TurboCore frequencies of 4.00 GHz and XFR ranging beyond 4.00 GHz. That of the R7-1700X is set beyond 3.80 GHz, and the R7-1600X beyond 3.70 GHz, R5-1400X beyond 3.90 GHz, and the R3-1200X beyond 3.80 GHz. There are no fixed values as to how much higher these frequencies will go, probably because AMD doesn't want to advertise clock speed figures consumers hold it to account for. The TurboCore frequencies, on the other hand, are achievable on even the included stock cooling solutions, or coolers that meet the TDP ratings of these chips.

The other thing I notice is we appear to have learned nothing more than the prior post as the XFR range is "4.0+"....useless thread is useless...
EDIT: after reading (again) what TDP is on wikipedia, I've figured that these two will have very different power consumption, but are limited to the 65W design. So... the 4C one should overclock way higher =)

Bottom line is, Turbo boost is guaranteed if basic conditions are in check. XFR just means extended potential which is not guaranteed and heavily depends on conditions.
TDP stands for Thermal Design Power and it's simply what the CPU manufacturers says will be the absolute maximum thermal output from a CPU when running at 100%. It's so you as a consumer can buy a matching cooling solution.
It's highly likely that the Ryzen 5 will draw a lot less power than the Ryzen 7, but it it's the same processor with parts of the chip disabled to make it a different SKU, then the power draw might not be half. We don't know how well AMD has succeeded in disabling the unused parts and there might be some power leakage here. Even so, AMD didn't design these to be the most power efficient parts in its lineup and it's likely we'll see more power efficient parts in the future, much like Intel's T-series of processors.
My router has similar situation. It comes with a 30w charger but I seriously doubt it can ever reach 15w at peak.
Intel has stagnated, AMD has caught up... don't ignore their lead again or the cycle will continue.
