Although the third-generation Ryzen processor based on the 7nm Zen2 architecture has become the main market force, in fact the price drop is touching on the first and second generation ryzen still quite popular. Interestingly, the user found that the prototype YD1600BBAE Ryzen 5 1600 processor was quietly replaced with YD1600BBAF, by CPU-Z, HWinfo and other hardware detection tools, the AF version of the new processor actually upgraded to 12nm process.
The new process not only results in lower power consumption and heat, but also improves performance stability.
Users on Reddit have reported that the old chip, under any load, can easily drop to 3.4GHz at a frequency, even if it is only single-core and dual-core, while the new chip can “go” for longer at 3.7GHz, which is only 200MHz lower than the 2600.
It is important to note that AMD is attached to the AF processor with a Wraith Stealth heatsink, not a Wraith Spire.
As for why AMD quietly made this adjustment is not known, there is speculation that 1600 demand exceeds 2600, there is speculation that GF for some reason closed the 14nm production line.
