Upgrading the first generation of Ryzen processors to 12nm lithography

The first member of the first generation of AMD Ryzen processors, called Ryzen 5 1600 with 6 cores and 12 processing threads was introduced in 2017. This processor was built using 14nm lithography based on the Zen architecture . But now it seems that a new version of the said processor with 12 nm lithography and Zen + core architecture has been seen in the market.

The first way to distinguish between the new model and the old model of this processor Pay attention to the serial number written on the IHS of the processor. IHS or integrated heat spreader is the integrated heat spreader system on the processor. The serial number on the IHS for the 2017 version of this chip is YD1600BBAE, while the newer Ryzen 5 1600 comes with the code YD1600BBM6IAF. First, in September, the new version of the processor, which is also named AF based on the last characters of its model, was seen in some online retailers. hardware diagnostic tools including CPU-Z and HWInfo also identified the AF model as a 12nm lithography processor. AMD has not confirmed anything about this yet. As a result, there is no guarantee for the validity of the reports.

  • AMD is again increasing the number of cores of Ryzen processors

According to the reports, the Ryzen 5 1600 processor is now manufactured with the Zen+ architecture and compared to the old Zen cores, it has about 3-5% better IPC and has seen some improvements in the field of overclocking. IPC stands for Instruction per Clock, which means the average number of executable instructions in processor cores per clock cycle.

Using the Zen + microarchitecture from the beginning in the Ryzen 5 2600 processor has caused this chip to show huge improvements compared to the old version of the Ryzen 5 1600. Although the difference in microarchitecture makes the Ryzen 5 1600 not perform as well as the second generation of Ryzen processors, the considerable leap in performance of the AF version of this processor is undeniable. Finally, the Ryzen 5 2600 chip has a higher clock speed and boost than the Ryzen 5 1600 processor, and the use of the Zen+ architecture did not significantly increase the processing frequency and boost in the AF model, however, it seems It turns out that the PBO (Precise Boost) technology has had a more positive effect on the AF type.

At first, it was thought that the AF ID was used to classify chips between two steps different from 14nm dies. Chip manufacturing companies code their products asstep and classify based on the updates applied to the chip structure. But recently, a user on tech website Reddit has received an AF version of the Ryzen 5 1600 processor. The microarchitecture renewal in this chip has caused a slight increase in the boost frequency. The boost speed in the AF model is around 3.7 GHz, which is 100 MHz higher than the reference processor with a boost frequency of 3.6 GHz. But this amount is not very impressive. A Reddit user commented on the AF version’s boost frequency:

The Ryzen 5 1600 main processor boosted up to 3.4 after the cores were loaded once or twice. GHz decreases. Meanwhile, the AF version of this processor maintains its 3.7 GHz boost speed for a longer time. The boost frequency of the AF version is only 200 MHz lower than the Ryzen 5 2600 processor.

At this moment, the reason for using a 12nm die in the mentioned processor is in an aura of ambiguity. Maybe there was just a mistake in the microcode of the chip, and maybe AMD had usable dies from the Ryzen 5 2600 processor and decided to use them in the AF version. It is also possible that GlobalFoundries, which is the manufacturer of 14nm dies for AMD, has shut down the lithography department for some reason. In any case, consumers have to buy the AF version of this processor instead of the AE version.

AE model at Amazon It sells for $120. The price of Ryzen 5 2600 processor is also $120. So if you want to spend $120 on a processor, considering the Ryzen 5 2600 processor’s superior performance, it’s better to buy this chip. Meanwhile, the AF version, which potentially performs better than the AE version, retails for $85. The AF version of the processor is sold with a Wraith Stealth type cooler; While the main Ryzen 5 1600 processor comes with a weaker Wraith Spire cooler. Tests show that the AF version is 5 degrees Celsius hotter than the reference model when gaming, as a result, the more powerful cooling makes the AF version more worth buying.
