Announcing AMD EPYC™ 4005 Processors

Affordable, enterprise class server solutions for small and medium businesses and dedicated hosting providers 

As a server business leader at AMD, I get the privilege of sharing exciting innovations that truly meet our customers’ needs. Today, I’m thrilled to introduce the latest addition to the AMD EPYC family: the AMD EPYC™ 4005 Series processors. 

These new processors are purpose-built to support small and medium-sized businesses (SMBs), dedicated hosting providers, and branch office IT environments that need cost-effective compute power that is reliable and easy to deploy. In a market long dominated by a single vendor, we are disrupting the status quo with compelling price-to-performance ratios and total cost of ownership (TCO) that make AMD a strategic choice for these verticals. 

Advancing AMD EPYC 4000 series 

The AMD EPYC 4005 Series is part of the AMD Enterprise Class CPU offerings, building on the previously released 4004 family. It’s based on the ‘Zen’ architecture designed to deliver high performance and efficiency. With core counts ranging from 6 to 16, TDP options between 65W and 170W, up to 192GB DDR5 ECC memory support, and PCIe® Gen 5 connectivity, the 4005 Series is designed for workloads that demand a balance of power, scalability, and affordability. 

These processors power servers that are incredibly easy to deploy, making them an excellent fit for SMBs that don’t have deep IT benches or large budgets for consulting services. Ideal for running office-based workloads, building out branch infrastructure, or managing hosted IT services, these processors deliver reliable performance. 

Advancing Innovation: Why Now is the Time to Switch

A lot of organizations stick with the status quo simply because it is what they have always done. But in doing so, you may be missing out on real business benefits. For example, in addition to leading performance and energy efficiency, AMD EPYC 4000 series processors offer up to 16 cores, allowing you to maximize your Windows Server® Standard or Datacenter license which is sold with a base of 16 cores. Competitive solutions max out at 8 cores – leaving half of your license unused.  The additional cores can also provide headroom to grow with your business without constant reinvestment. 

Built for the Real World 

We’ve designed the 4005 Series with today’s real-world use cases in mind: 

• Office infrastructure: Quiet, power-efficient towers for offices without dedicated server rooms 

• Remote office/ branch office: Reliable compute that scales as your teams grow 

Dedicated hosting: Energy-efficient performance that helps reduce operational costs OVHCloud, a leading hosting provider, is already deploying EPYC 4005 CPUs following their success with our 4004 Series. Their need for high performance, affordability, and energy efficiency made AMD the clear choice. That same value proposition is what we’re bringing to SMBs across the globe.

Advancing Reseller and MSP Growth 

EPYC 4005 processors revolutionize offerings for resellers and managed service providers (MSPs), empowering them to deliver enhanced performance, scalability, and efficiency.  

• Highly competitive price points for entry-level systems 

• Enterprise-class features (RAID, ECC memory, AVX512) 

• Leadership core density in class, optimized for Windows Server licensing 

There are also real opportunities to build high-margin services on top of this platform. Whether you're onboarding new clients, supporting a wider range of applications, or delivering AI capabilities, EPYC 4005 gives you the flexibility to scale without sacrificing profitability. 

The Ecosystem Is Here 

AMD EPYC 4000 series-based servers are available now from trusted OEM and ODM partners like Altos, ASRock Rack, Gigabyte, Lenovo, MiTAC, MSI, and Supermicro. Whatever your configuration needs, the ecosystem is ready. 

Compatibility Without Compromise 

We know compatibility can be a concern, especially in environments with legacy software or hardware. AMD EPYC 4005 processors are x86 compatible, offering seamless deployment for existing workloads. They are certified on popular Server OSes like Windows Server, RHEL, SLES, and Ubuntu®, and are supported by leading OEM/ODMs to help ensure the systems integrate easily into your IT environment. 

With the launch of the EPYC™ 4005 Series, we’re bringing the power of EPYC innovation to a broader audience than ever before. Designed for small and medium-sized businesses, hosting providers, and IT leaders, this platform combines enterprise-grade performance, energy efficiency, and exceptional value—all in a right-sized solution. 

Now is the time to reimagine what’s possible for small business IT. Whether you're modernizing infrastructure, scaling services, or simply demanding more from your investment, EPYC 4005 delivers uncompromising performance and flexibility to help you grow with confidence. 

Don’t settle for yesterday’s limits. Step into what’s next—powered by AMD.
