In the battle for the next-generation data center, AMD hopes to advance x86 processing performance and efficiency with its latest line-up of AMD EPYC 9004 Series CPUs. Formerly known by the codename 'Genoa', these new processors are designed to meet the demanding requirements of today's data center workloads and they do so by using a number of new technologies.

Notably, the new 5nm 'Zen4' processors from AMD feature SKUs up to 96 cores, compared with a maximum of 64 cores in the previous AMD EPYC™ 7003 'Zen3' CPUs. According to AMD, an EPYC 9004 Series processor with 96 cores can deliver "3x the integer performance and speed" of technical applications with "2.5x the floating-point performance" ^[1] versus a comparable x86 system.

Balancing memory and bandwidth

Performance is also enhanced by AMD's support for 12x DDR5-4800 memory channels, boosting the maximum memory capacity from 4TB per socket in 3rd Gen EPYC CPUs to 6TB per socket (with a peak memory bandwidth of 460GB/s) for 4th Gen 9004-Series processors. "Having more, and more powerful CPU cores creates a higher demand for memory," explains AMD. "Additional memory channels and higher bandwidth keeps this equation in balance." ^[2]

Speaking of bandwidth, the latest AMD EPYC 9004 Series processors also support the PCIe 5.0 standard. This allows for faster data transfer between the processor and other system components, such as storage drives and networking interfaces. This, in turn, improves performance and scalability. The 4th gen AMD EPYC processors can support up to 128 PCIe Gen 5 lanes in a single socket configuration and up to 160 lanes in a dual-socket setup.

In addition, 4th Gen AMD EPYC processors also provide CXL 1.1+ support for memory expansion, helping customers to meet demands for larger in-memory workload capacity. At the same time, silicon level data security is further enhanced through an evolution of AMD Infinity Guard, which features twice the number of encryption keys compared to previous AMD CPUs.

Tyan servers powered by AMD EPYC™

All of these features are integrated into the latest Transport server platforms from Tyan, which support AMD EPYC 9004 Series processors up to 96 cores, along with DDR5 memory, PCIe 5.0, and CXL. For example, the Tyan Transport SX TS70-B8056 is a 2U server that supports the entire EPYC 9004 Series processor line all the way up to 400W of TDP, taking full advantage of 12 memory channels by incorporating 24 DIMM slots compatible with DDR5 4800 memory.

The Tyan Transport SX TS70A-B8056, meanwhile, combines AMD EPYC 9004 Series processors with 26x 2.5-inch U.2 NVMe drive bays, 24 DIMMs and high-end networking support provided by a PCIe 5.0 x16 OCP v3.0 LAN mezzanine slot. It's ideal for running high density, high performance flash applications. In contrast, the Tyan Transport HX FT65T-B8050 is a 4U, rack-convertible workstation platform that mixes 9004 Series CPU support with 8 DIMM slots and two double-wide GPU accelerators for HPC deskside needs.



AMD EPYC 9004 Series processors will provide increased performance, reliability, and scalability in the data center, with support for increased CPU clock speeds, DDR5 memory, PCIe 5.0, and CXL. The 4th Gen CPUs are at the heart of the latest world class server platforms from Tyan, maximizing the technology benefits while delivering high performance, improved TCO, reduced energy costs (by deploying fewer, more powerful servers) and enhanced data security.

Built for the most demanding technical computing workloads, the Tyan Transport series is a line of world class server platforms based on AMD's latest technology, including 4th Gen AMD EPYC™ processors. For more information about Tyan's latest products, click here.
