Picasso desktop APU might have tipped up

AMD engineering sample could be it

The codename given to an AMD engineering sample processor has been leaked online and might be a desktop APU from the Picasso range based on the Zen+ microarchitecture.

The series is just mobile processors at the moment. To be fair we and the tech press are extrapolating rather a long from the name of the mysteriously titled AMD engineering sample “PD340SC5M4MFH_37/34_Y, AMD Myrtle-PCO” which was leaked online by Tum Apisak.

Reddit readers  logically broke down the name and hit a snag with the the first letter. “P” points to production EPYC, which is of course AMD’s server series. The “D” is probably “desktop”, while the “340” part could hint at the APU’s final production name.

“S” could be “SKU”, and then “C5” is for 65 W Raven Ridge. “M” is for AM4 (socket), “4” means four cores, and “M” is likely to be a cache memory reference (4x 512kB L2 + 4 MB L3).

“FH” is believed to be a stepping or revision code, and the "37" and "34" likely point to 3.4 GHz base clock and 3.7 GHz boost clock. “Myrtle” also refers to AM4 testing.
