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.

It will be interesting to see if there is also a settable TDP for these, so you could benefit from the speed for short bursts (like phones) but restrict the comnsumption/heat for smaller builds/24/7 use etc.
It all sounds very flexible anyway. :)

You have the Xs, non Xs, Pros and no Pros,
Different TDPs among the above mentioned,
3 coolers (HS55, HS65, HS81) under 3 categories (A, B, F)
You have the R5 that can either be a 6/12 or a 4/8,
Cherry on top you have the XFR thing
oh, and there's temps, the 1800X is supposed to stay below 60C, while the Pro 1800 (same TDP) can reach 72C
Confusing
i5 like performance <150$
i7 like performance <200$
i7 HE like performance <500$
Prices are amazing, but we have to see performance.
Based on the prices, and considering there is no point for AMD to undercut Intel by much, I would assume the performance to also be like 2/3 of the comparable Intel CPU, probably targeting for a 10-20% better performance/price ratio. At least this is what I would do if I would be AMD management.
That would give a nice competitive product, while the margins will be huge compared to Intel as they'll not have the 60% die space wasted due to the iGPU, which nobody (99% of the desktop users) uses anyway.
Now AMD needs to come also with a nice mobile solution, this time with integrated graphics, as businesses need that and to use integrated for a laptop is much more common than for the desktop.
