AMD appears to have confirmed that its Ryzen 7040 “Phoenix” APUs are available hybrid flavors that includes Zen 4 and Zen 4C cores.

AMD Ryzen 7040 “Phoenix” APUs Come In Zen 4C & Zen 4 Hybrid Designs: Ryzen 5 7440U Amongst The First

Speaking to XDA-Builders, AMD confirmed the existence of a second Phoenix SKU powering its Ryzen 7040 APU lineup. Whereas unique Phoenix chips are based mostly totally on the Zen 4 and RDNA 3 graphics structure, the second Phoenix SKU, often known as Phoenix 2, makes use of a hybrid Zen 4 + Zen 4C mixture for the CPU cores.

As per the confirmed info, the AMD Phoenix 2 Hybrid APUs will characteristic a dual-core Zen 4 and quad-core Zen 4C implementation on the identical CPU die and the RDNA 3 graphics cores for its iGPU. The primary APU to utilize such a configuration has additionally been confirmed to be the Ryzen 5 7440U which is able to characteristic 6 cores and 12 threads. The chip will even be out there in the usual Zen 4-only variation which might permit AMD to dual-source the manufacturing based mostly on demand for these chips.

In my correspondence with AMD, a number of key particulars about this small APU (presumably Phoenix 2) had been confirmed, and it is not only a easy hybrid model of the bigger 8-core Phoenix design used within the higher-end fashions.

The unique rumor recommended that Phoenix 2 would characteristic within the Ryzen 3 7440U and Ryzen 5 7540U, and for the reason that 7540U is marketed as not having Ryzen AI and 4 GPU cores, that is believable. Nonetheless, I requested AMD to verify whether or not the Ryzen 5 7540U used this new APU, and I used to be instructed it is “simply the 7440U for now”.

Now technically, having Zen 4 and Zen 4C cores should not make for an enormous distinction as a result of, not like Intel’s P-Core and E-Core implementation, the Zen 4 variants characteristic the identical ISA & the variations primarily lay inside the L3 cache per core which is decreased to 2 MB from 4 MB on the usual Zen 4 cores. Which means that the AMD Ryzen 5 7440U “Phoenix 2” APU will characteristic 16 MB of L3 cache.

The present 6-core Ryzen 7040 APUs additionally include 16 MB of L3 cache so as soon as once more, there isn’t any main distinction. An enormous distinction nevertheless would be the package deal measurement since Zen 4C cores are extra compact and have a a lot smaller die measurement of 137mm2 versus the usual Phoenix chips that measure 178mm2.

Phoenix2 high die is 7540U (2 excessive+4 low), however 7540U is twin sourced: some chips can be full Phoenix2 dies (2+4), some can be lower down Phoenix1 dies (since Zen4c is only a downclocked Zen4, it is simple to bin it down from 8 high-clock cores to 2 high-clock + 4 low-clock cores)

AMD lately said that it will not be following Intel’s hybrid P-Core & E-Core architectural method and somewhat use a mixture of IPs of the identical ISA which are workload-optimized. There have been additionally studies of a Ryzen 5 7540U APU with a 2+4 (Zen 4 + Zen 4C) configuration however that hasn’t been confirmed by AMD but. It’s anticipated that the AMD Phoenix 2 APUs will launch someplace between This fall 2023. The APUs will in all probability be utilized in power-efficient PC gaming handhelds or laptops.
