AMD "Zen 4" EPYC 9004
AMD EPYC 9004 Series processors include up to 96 "Zen 4" microarchitecture-based cores, built on 5nm process technology. "Zen 4" enables leadership memory bandwidth and capacity with 12 DDR5 channels, as well as next-gen I/O with PCIe 5.0 and memory expansion with CXL. Three goals have drive the design of the AMD EPYC 9004 Series processors:
- Performance, with a goal of double-digit instructions-per-clock (IPC) and frequency improvements.
- Latency, with a goal of reducing average latency with higher cache sizes and effectiveness.
- Throughput, with a goal of reducing dynamic power to enable significantly higher core counts.
Efficient by Nature
AMD EPYC processors power the most energy-efficient x86 servers in the game, delivering exceptional performance and lower energy consumption. The EPYC 9004 Series doubles the I/O Bandwidth o the CPU from past generations by incorporating PCIe Gen 5 capabilities onto the I/O. The heart of the AMD Infinity Architecture is a leadership interconnect that supports extraordinary levels of scale at every layer. As a result, the architecture delivers breakthrough performance and efficiency to deliver on the promise of next generation computing.
New Instructions
The "Zen 4" core introduces new instructions designed to advance artificial intelligence, machine learning, and high-performance computing workloads. The full set of AVX-512 instructions are implemented to match industry standards. These include BFLOAT16 and Vectorized Neural Network Instruction (VNNI). AMD's implementation of these data heavy instructions enables applications that are hard coed for AVX-512 to work without modification.
Security Enhancements
Building upon the security features of the previous generation, the "Zen 4" core introduced the capability for guest operating systems in virtualized environments to run exclusively on one core thus introducing further solutions that can help protect against side-channel attacks targeted at cached memory. New support for virtualized environments includes secure multi-key encryption (SMKE) that enables hypervisors to selectively encrypt address space ranges on CXL-attached memory.
