A pair of AMD Zen 4 engineering samples have appeared online

Looking to the future: AMD announced Zen 4 earlier this week at CES 2022, but they didn’t go into details. So, let the Ryzen 7000 series leak begin.

A pair of engineering samples has been find in the public database of the MilkyWay @ home project, which uses distributed computing to create a model of our galaxy. They both ran the app for a few days at the end of December.

The couple identified themselves as “Family 25”, which is how we know they are based on the Zen 4 architecture. One of their OPNs ended with “665” while that the other ended with “666”, indicating that they are adjacent to each other in the schedule.

It’s interesting because one of them had 8 cores and the other had 16 cores, so there might not be a 12-core model.

Database entries also revealed that they had 1024KB of L2 cache per core, compared to 512KB used by all previous Zen architectures. Beyond that, however, the entries didn’t say much else about the processors.

Oddly enough, they were both paired with an Nvidia RTX 2080, which suggests they’re in the hands of an OEM, not AMD themselves. This fits in with AMD’s plan to release them in the second half of the year.

In the meantime, there will be a lot more leaks as OEMs test their AM5 motherboards, DDR5 memory, and PCIe 5.0 peripherals with the new processors.
