AMD Zen 4 Ryzen 7000 series have entered pre-production
AMD’s Ryzen 7000 series CPUs have surfaced as engineering samples, meaning they have entered the pre-production stage of development.

AMD Zen 4 ‘Raphael’ CPUs are the next big up-and-coming CPU release. Expected to release around Q3 2022 these 5nm chips have been one of the highest anticipated CPU releases ever, as AMD drops its much loved AM4 platform in the wake of a newer more advanced platform, AM5. But with the Zen 4 pre-production, we have news surrounding both.
AMD 7000 series CPUs were announced at CES 2022, and along with the announcements came some pretty big promises in terms of performance, a 15% increase in performance with a 30% power reduction. All of this along with never before seen features on the AMD platform such as PCIe Gen 5 and support for DDR5 RAM as standard.
According to @BenchLeaks on Twitter, It looks like AMD’s first AMD 7000 series Engineering sample has made its way onto the MilkyWay@Home specification sheet. This brand new information is comprised of CPU family, model and stepping name. There’s also some information surrounding CPU core count and cache size, indicating that the Zen 4 CPU is getting close to completion. But what does Zen 4 pre-production mean?
The information on the MilkyWay@Home specification sheet is a little vague, however, as the cache size, for example, is only listed as 1024KB no indication whether or not this is an L1 cache or a per-core cache measurement.
What is listed in this spec sheet, however, is the AMD Eng Sample: 100-000000514-03_N the family is 25, model 97 and stepping 1. Some of the recent leaks have shown models with steppings of 96 however, but we can assume it’s still a pre-production model that isn’t yet ready for the public market.
MilkyWay is reported to bundle the cores and threads together and listing them as one metric, much like an OS bundles cores and threads together as ‘Logical processors’.
This suggests that the engineering sample we have must be a lower-end eight-core 7000 series CPU, Possibly a Ryzen 5.
Clock speeds seem to be taking a massive leap in terms of performance, with max boost speeds breaking the 5GHz barrier. That’s something AMD has yet to manage and probably won’t until the release of Zen 4.
The AMD Zen 4 Raphael CPUs should release within Q3 2022 as recent rumours suggest, this also implies that the long awaited X670 chipset AM5 motherboard is probably well into pre-production itself. This is because we believe the two are set to release side-by-side.
