Additionally, Zen 4 supports new AMD EXPO SPD profiles for more comprehensive memory tuning and overclocking by the RAM manufacturers.

Unlike Intel's XMP, EXPO is marketed as an open, license and royalty-free standard for describing memory kit parameters, such as operating frequency, timings and voltages.

[11] All Zen 4 Ryzen desktop processors feature 28 (24 usable + 4 reserved) PCI Express 5.0 lanes.

[26][27] On April 1, 2024, AMD quietly released the Ryzen 8000 series of desktop processors without integrated graphics.

[38] Common features of Ryzen 7000 HEDT/workstation CPUs: On January 4, 2023, AMD announced its Phoenix and Dragon Range series of mobile processors based on Zen 4 at the 2023 Consumer Electronics Show (CES).

The Phoenix processors target the mainstream notebook segment, feature an AI accelerator branded as "Ryzen AI", similar to Apple's Neural Engine, and are of a monolithic chip design, while the Dragon Range processors target the high-end segment, providing core counts up to 16 cores and 32 threads, and are built on a multi-chip module design, utilizing an I/O die and up to two core complex dies (CCDs).

On November 10, 2022, AMD launched the fourth generation (also known as the 9004 series) of EPYC server and data center processors based on the Zen 4 microarchitecture, codenamed Genoa.

[48] Genoa features between 16 and 96 Zen 4 cores, alongside PCIe 5.0 and DDR5, designed for enterprise and cloud data center clients.

[53] In addition to the reduced core footprint, die space is further saved in the Zen 4c CCD via the use of denser 6T dual-port SRAM cells and an overall reduction of L3 cache to 16 MB per 8-core CCX.

"[54] Unlike Intel's competing Gracemont E-cores, Zen 4c features 2 threads per core with simultaneous multithreading.

Intel's Gracemont E-cores lack support for the AVX-512 instructions contained in Golden Cove P-cores.

With up to 64 cores and 128 threads, Siena is designed with a lower cost platform in mind for entry-level server, edge computing, and telecommunications segments where higher energy efficiency is a priority.

[60] Zen 4c made its debut outside of server processors in the Ryzen 7040U series, codenamed "Phoenix 2", which launched on November 2, 2023.
