AMD has announced its 4th Gen EPYC processors, confirming the specifications for 18 new models that promise what the company has described as unmatched performance for professional workloads thanks to improvements enabled by the new Zen 4 architecture. According to a press release, 4th Gen AMD EPYC processors boast up to 2.8x more performance versus the competition and up to 54% less power, headlined by the 9654, a flagship chip that features 96 cores, a boost clock of 3.7 GHz, and $11,805 1kU pricing. The partner list includes the likes of Microsoft, Google, and Dell, the latter of which complemented AMD’s announcement with its own reveal of new PowerEdge servers that feature 4th Gen EPYC processors.
AMD on what 4th Gen EPYC processors bring to businesses:
- Support Performance and Efficiency. With up to 96 cores in a single processor, the new AMD EPYC processors can enable customers to deploy fewer and more powerful servers to continue to meet their compute needs. This allows them to drive greater flexibility within the data center that can be leveraged to address business sustainability goals and drive real-world dividends.
- Help Keep Data Secure. Through a “Security by Design” approach, AMD continues to deliver enhanced security features in x86 CPUs. The 4th Gen AMD EPYC processor series expands on AMD Infinity Guard6, a cutting-edge set of features that offers physical and virtual layers of protection. With 2X the number of encryption keys compared to previous generations, 4th Gen EPYC processors help customers keep data secure, whether it is stored locally, in the cloud, or residing in storage.
- Use the Latest Industry Features and Architectures. These processors continue to provide customers with an “all-in” feature set, with customers just needing to pick the core count and frequency that matches their workload needs. The 4th Gen AMD EPYC processor introduces support for DDR5 memory and PCIe Gen 5, which are critical for AI and ML applications. In addition, 4th Gen AMD EPYC processors support CXL 1.1+ for memory expansion, helping customers to meet demands for larger in-memory workload capacity.
“Choosing the right data center processor is more important than ever, and 4th Gen EPYC processors deliver leadership in every dimension,” said Dr. Lisa Su, Chair and CEO, AMD. “The data center represents the largest growth opportunity and most strategic priority for AMD, and we are committed to making AMD the partner of choice by offering the industry’s broadest portfolio of high-performance and adaptive computing engines. We have built the best data center CPU roadmap in the industry, and with 4th Gen EPYC we deliver another major step forward in performance and efficiency to make the best server processor roadmap even better. With a significantly expanded set of solutions on-track to launch from our ecosystem of partners, customers selecting 4th Gen EPYC to power their data centers can improve performance, consolidate their infrastructure, and lower energy costs.”
