AMD has already stated that the first Zen 4-based chips would release later this year, likely in late Q3 or early Q4. Although we don't have a specific date, it seems things are going as the company planned, as the first pre-production samples are already hitting benchmark databases.

The news comes from Benchleaks, which found a Zen 4 CPU sample on MilkyWay@home. It may not be the best tool for comparing CPU performance as a benchmark, but the information on the entry is useful. One example is the CPU name, which suggests the upcoming Raphael chips are already in pre-production.

Looks like Raphael got it's production model ID (the previous one was 96), probably stepping RPL-B1.

The listing shows that the processor's name is “AMD Eng Sample: 100-000000514-03_N [Family 25 Model 97 Stepping 1]”. Although it may seem confusing, pay attention to the ‘Model 97' part.

Previous engineering samples were listed as ‘Model 96', but this one is one version above. Benchleaks claims the ‘Model 97' is the production ID, but the sample is still referred to as an engineering sample. As such, it may be better to refer to it as a pre-production sample.

KitGuru says: With the first Zen 4-based chips coming in about half a year, we should start seeing more benchmark results. Hopefully, these will be from Geekbench, CPU-Z and similar benchmark tools that make it easier to compare with other CPUs.
