For example, i AMD Ryzen 5 1600 The Original came on the market with six cores and a dozen processors, and was manufactured with a 14 nm process for GlobalFoundries, but now a new version called "AF" at some retailers is priced at 85 euros, and apparently made with 12 nm Zen + structures
AMD production facilities
The second generation of Lyzen processors are the ones that set the node at 12 nm, and although this process did not offer any small transistors or new structure, it does not bring about efficiency improvements compared to the first-generation processors at 14 nm LPP. AMD developed the Zen architecture in the process, to name it Zen +
Of course you can also test it with tools such as the CPU-Z, where you will see a processor to produce a processor identified as 12 nm and not 14 nm for the original processors.
The fact is that the situation is real, too AMD puts on the market some of the first-generation Ryzen controllers updated with the process at 12 nm GlobalFo. And best of all, it seems that even though the third generation is on the road, they continue to sell first-generation processors (and at those prices it's no surprise).
Is there a real performance improvement?
Yes, here we go in terms of the user experience, but there are several threads on reddit where we can find several users who are new company owners claiming their development. For example the user "vogonpoetry" said that his processor has it boost speed of 3.7 GHz, 100 MHz over the original processor version. He also said that with the old processor this speed was only 3.4 GHz in 1-2 cores, while the newest one was stored at 3.7 GHz, only 200 MHz less than the Ryzen 5 2600.
It is also interesting that the Ryzen Master did not see the processor until it installed the latest version:
In the end, they point out that AMD doesn't seem to use the best Zen + architecture on these processors because its power consumption is basically the same as first-generation Ryzen, but you already know that with each processor's overhead it's a world and everyone is going up differently.
