5th Generation AMD EPYC™ Processors for SP5 Socket

The SP5 socket has reached its pinnacle form with 5th Generation AMD EPYC™ processors. The same successful platform that was shared by AMD EPYC™ 9004 & 8004 series processors is now the same one for AMD EPYC™ 9005 series processors. With up to 192 cores, increased frequencies and cache, this top tier performance platform targets general purpose, cloud native, and technical computing. Building on the advantages of the EPYC™ 9004 series, the new EPYC™ 9005 series adopts the 3nm process with AMD “Zen5” and “Zen5c” core architecture, excelling in both energy efficiency and cost optimization.
Product Overview

High Performance
Supports NVIDIA HGX™ B300
NVIDIA HGX™ B300 is built for the age of AI reasoning with enhanced compute and increased memory. Featuring 7X more AI compute than Hopper platforms, 2.1TB of HBM3E memory, and high-performance networking integration with NVIDIA® ConnectX®-8 SuperNICs, Blackwell Ultra delivers breakthrough performance on the most complex workloads from agentic systems and reasoning, to real time video generation for every data center.

Power Efficiency
Automatic Fan Speed Control
These servers are equipped with Automatic Fan Speed Control to optimize cooling and power efficiency. Fan speeds are automatically adjusted based on temperature readings from strategically placed sensors, ensuring optimal airflow and energy usage.

High Availability
Smart Ride Through (SmaRT) 
To minimize server downtime and prevent data loss during AC power interruptions, we incorporate Smart Ride Through (SmaRT) in all our server platforms. In the event of a power loss, the system will throttle to maintain availability while reducing power consumption. Capacitors in the power supply provide 10-20ms of backup power, giving the system enough time to switch to a backup power source and ensure continuous operation.
Smart Crises Management and Protection (SCMP)
SCMP is a patented feature which is deployed in servers with non-fully redundant PSU design. With SCMP, in the event of faulty PSU or overheated system, the system will force the CPU into an ultra-low power mode that reduces the power load, which prevents the system from unexpected shutdown and avoids component damage or data loss.

Dual ROM Architecture

If the ROM that stores the BMC and BIOS fails to boot, the system will reboot with the backup BMC and/or BIOS replacing the primary. Once the primary BMC is updated, the ROM of the backup BMC will automatically update the backup through synchronization. For the BIOS, it can be updated based on user's choice of firmware version.
Hardware Security
Optional TPM 2.0 Module
For hardware-based authentication, the passwords, encryption keys, and digital certificates are stored in a TPM module to prevent unwanted users from gaining access to your data. TPM modules come in either a Serial Peripheral Interface or Low Pin Count bus. 
User Friendly

Tool-less Drive Bays Design
Clipping mechanism secures the drive in place. Install or replace a new drive in seconds.

Certified Ready with Software Partners
Being a member of key software alliance partner programs enables us to rapidly develop and validate joint solutions, enabling our customers to modernize their data centers and implement IT infrastructure and application services with speed, agility, and cost optimization.
