Strix Point: AMD also adds E-Core to its CPUs!

For its future mobile processors, AMD would follow Intel’s lead. The brand would offer its Strix Point models, featuring a hybrid core configuration with P-Core and E-Core. All based on the Zen 5 architecture!

Strix Point: Zen 5 hybrid cores!

The screenshots from Performancedatabase.com show the CPU in action. We learn that it’s an engineering sample with a hybrid core configuration. This twelve-core model features four P-Cores and eight E-Cores. AMD follows Intel’s model, mixing high-performance cores with more economical ones.

If we follow the current logic (Zen 4 and Zen 4c), the P-Cores will be in Zen 5 and the E-Cores in Zen 5c. The latter would then operate at slower frequencies, have lower power limits and benefit from less L3 Cache. This reduces power consumption, heat generation and die space.

Last but not least, there’s the “monolithic” design, i.e., a single large chip. According to TechpowerUp, we can expect P-Cores and E-Cores to be grouped in separate CCXs with their own L3 cache. P-Cores would then have 4 MB of L3 per core, compared with 512 KB for E-Cores. As for L1, the amount would be identical regardless of core type (48 kB of L1D and 32 kB of L1I), while L2 would be present at 1 MB per core.

As for engraving, TSMC would be in charge, and the whole unit would be engraved in 4 nm. The TDP reported by the info software is 45 W. And let’s not forget the massive performance gains promised by Zen 5.
