EPYC 5th Generation

The Leading CPU for AI

AMD EPYCâ„¢ 9005 processors provide end-to-end AI performance.

Maximizing Per-Server Performance

AMD EPYC™ 9005 can match integer performance of legacy hardware with up to 86% fewer racks2, dramatically reducing physical footprint, power consumption, and the number of software licenses needed - freeing up space for new or expanded AI workloads.

Leadership AI Inference Performance

Many AI workloads—language models with 13 billion parameters and below, image and fraud analysis, or recommendation systems run efficiently on CPU-only servers that feature AMD EPYC™ 9005 CPUs. Servers running two 5th Gen AMD EPYC 9965 CPUs offer up to 2x inference throughput when compared to previous generation offerings.

Maximizing GPU Acceleration

The AMD EPYC™ 9005 family includes options that are optimized to be host-CPUs for GPU-enabled systems to help increase performance on select AI workloads and improve the ROI of each GPU server. For example, a high frequency AMD EPYC 9575F processor powered server with 8x GPUs delivers up to 20% greater system performance than a server with Intel Xeon 8592+ processors as the host CPU with the same 8x GPUs running Llama3.1-70B.

DDR 5

DDR5—Packing Power and Performance into a New Generation

DDR 5
Increased Banks and Burst Length

DDR5 doubles the banks from 16 to 32. This allows for more pages to be open at a time, increasing efficiency. Also doubled is the minimum burst length to 16, up from 8 for DDR4. This improves data bus efficiency, providing twice the data on the bus, and consequently reduces the number of reads/writes to access the same cache data line.

Improved Refreshes

DDR5 adds a new command called SAME-BANK Refresh, which allows a refresh of just one bank per bank group, versus all banks. When compared to DDR4, this command allows DDR5 to further improve on performance and efficiency.

Decision Feedback Equalization

DDR5 utilizes Decision Feedback Equalization (DFE) to provide stable, reliable signal integrity on the module, required for high bandwidth.
