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.
