AMD Releases EPYC 4005 Series Workstation CPUs, Featuring Up to 16 Zen 5 Cores With Impressive Performance Figures
AMD has officially launched its newest line of enterprise-focused CPUs under the EPYC 4005 Series, codenamed "Grado." These Zen 5-based processors are designed to power small and medium business infrastructure, hosted IT platforms, and enterprise-class servers with a strong emphasis on value, simplicity, and high performance per dollar.
In AMD's official release, the company highlighted how these processors provide an accessible solution for businesses that need scalable performance without the cost or complexity of high-end enterprise CPUs. Leveraging the same AM5 socket as the EPYC 4004 Series, the new CPUs simplify deployment while maintaining support for a wide range of form factors, including towers, rackmounts, and blades.
Scalable Zen 5 Performance at Every Tier
At the top of the stack is the EPYC 4585PX, offering 16 cores, 32 threads, a massive 128MB of L3 cache, and a clock speed that boosts up to 5.7GHz with a 170W TDP. It's priced at $699 (1KU). Just below it is the 4565P, which offers the same core count and clocks but comes with 64MB of L3 cache at a reduced price of $589.
Other options include the 4545P, a power-efficient 65W model with 16 cores and a base clock of 3.0GHz (boosting to 5.4GHz), priced at $549. The 4465P delivers 12 cores and 64MB cache for $399, while the 4345P offers 8 cores for $329. At the entry level, the 4245P provides 6 cores and 32MB cache with a clock boost up to 5.4GHz, priced at just $239.
These chips feature support for ECC memory, on-chip power management, and enterprise-grade reliability, making them ideal for edge compute, dedicated hosting, office virtualization, and light AI inference workloads.
Validation and Test Results
In benchmark testing using the Phoronix Test Suite, the EPYC 4565P was shown to outperform Intel’s 6th-gen Xeon 6300P by up to 1.83x, underscoring AMD’s leadership in performance-per-watt and multithreaded compute capability. Tests included a range of workloads such as web hosting stacks, database queries, memory bandwidth assessments, and synthetic AI tasks, where EPYC’s Zen 5 architecture showed both superior throughput and lower power draw under load.
Beyond synthetic testing, system integrators like Supermicro, ASRock Rack, Gigabyte, Lenovo, and cloud providers such as OVHcloud and Vultr have already begun integrating EPYC 4005 chips into turnkey server offerings.
Industry Response and Vision
AMD’s Corporate VP, Derek Dicker, stated:
“Growing businesses and dedicated hosters often face significant constraints around budget, complexity, and deployment timelines. With the latest AMD EPYC 4005 Series CPUs, we are delivering the right balance of performance, simplicity, and affordability, giving our customers and system partners the ability to deploy enterprise-class solutions that solve everyday business challenges.”
Lenovo echoed that sentiment in AMD’s official release, emphasizing that their new EPYC-powered platforms are designed to prepare small businesses for the AI era with cost-effective, high-reliability systems.
With the EPYC 4005 Series, AMD has broadened its workstation and server reach, offering a compelling alternative to Intel’s Xeon platform while reinforcing its commitment to scalable and efficient enterprise computing. Whether for edge deployments or compact data centers, the EPYC 4005 line offers power, flexibility, and performance—all at aggressive price points.
