AMD’s latest embedded roadmap has revealed the core counts that we can expect on the Zen 4 powered EPYC Genoa ‘7004’ and EPYC Embedded ‘3004’ series processors. Leaked by Videocardz, the roadmap confirms that Zen 4 is expected to launch in 2022.
Leaked Roadmap Confirms AMD EPYC Genoa ‘7004’ CPUs With More Than 64 Cores, EPYC Embedded ‘3004’ With Up To 64 Cores
According to the leak, AMD’s Zen 4 processors, or at least, the Zen 4 powered EPYC CPUs, will be launching in 2022. Based on the positioning on the roadmap, it looks like we are expecting a hard launch around mid of 2022. We will first get the Genoa ‘7004’ CPUs followed by EPYC Embedded ‘3004’ CPUs in Q1 2023. As for the details on what to expect from these CPUs, well they are listed below.
AMD EPYC Genoa ‘7004’ Server CPUs With Zen 4 Architecture
Talking about AMD EPYC Genoa CPUs themselves, the chips will pack a mammoth of 96 cores & 192 threads. These will be based on AMD’s brand new Zen 4 core architecture which is expected to deliver some insane IPC uplifts while utilizing the TSMC 5nm process node. A recent rumor had pointed out that the AMD EPYC Genoa CPUs are expected to offer up to 29% IPC uplift over Milan CPUs and a 40% overall improvement thanks to other key technologies that we will get to in a bit.
To get to 96 cores, AMD has to pack more cores in its EPYC Genoa CPU package. AMD is said to achieve this by incorporating a total of up to 12 CCD’s in its Genoa chip. Each CCD will feature 8 cores based on the Zen 4 architecture. That aligns with the increased socket size and we could be looking at a massive CPU interposer, even larger than the existing EPYC CPUs. The CPU is said to feature TDPs ranging between 120W-320W which will be configurable up to 400W.
The CPUs will be compatible with the LGA 6096 socket which will be the largest socket in existence at the time of its launch. Other than that, it is stated that AMD’s EPYC Genoa CPUs will feature 128 PCIe Gen 5.0 lanes, 160 for a 2P (dual-socket) configuration. The SP5 platform will also feature DDR5-5200 memory support which is some insane improvement over the existing DDR4-3200 MHz DIMMs. But that’s not all, it will also support up to 12 DDR5 memory channels and 2 DIMMs per channel which will allow up to 3 TB of system memory using 128 GB modules.

AMD EPYC Embedded ‘3004’ Server CPUs With Zen 4 Architecture
Moving over to the Embedded stuff, the EPYC Embedded ‘3004’ CPUs will also be featuring the Zen 4 core architecture and come with a multi-chip module solution. The chips would range from 32 to up to 64 cores while the TDPs are mentioned between 65W to 120W. The EPYC Embedded chips are soldered straight on the motherboard so we can expect a diverse range of platforms around them.
AMD just recently launched its Zen 3 powered Milan ‘7003’ CPUs so we can expect them to start talking about Genoa later this year or at CES 2022.
