AMD Announce 4th Gen EPYC Data Centre Processors, Why Should You Care?
November 11, 2022 News

If you are not in the System Builder or Data Centre business, then most likely processor launches come and go and though interesting, probably don’t garner more than a quick acknowledgement of more cores or a larger integer score.

So, what’s different this time? Why are AMD so excited about this launch and why should it matter to anyone anywhere who works in technology?

In order to help me answer the question, AMD kindly flew DTA over to San Francisco to hear from and chat with their product team directly at their Launch event “Together We Advance Datacentres.”

If you check the official headline on their press release, AMD tell us the following  “Offering Unmatched Performance, Leadership Energy Efficiency and Next-Generation Architecture, AMD Brings 4th Gen AMD EPYC ™ Processors to The Modern Datacentre”

As I listened to the presenters at the pre-event press briefing, what became clear is that it’s the sheer scale of the improvements in performance and efficiency that are somewhat breath-taking but more than that, it’s the OUTCOMES of these improvements which is why we all should care and take note. More on that shortly.

If you want to understand at a granular level how and why this new generation performs so well, check out the details below. Suffice it to say that compared to current processors from AMD or competitors like Intel, these 4th gen EPYCs are increasing performance and efficiency by numbers around 2x across every major metric worth measuring.

Let’s look at outcomes because it’s the outcomes that matter to those of us running the IT that runs our business.

Keeping it as simple as possible, the performance and energy efficiencies announced here mean that a cloud or hosting provider, can deliver the same performance with fewer servers but not just slightly less, an order of magnitude less, arguably never seen between generations of processors.  Painting the picture further for your hosting provider, this could mean delaying buying more racks or real estate for months or years and at the same time spending less on power consumption by significant amounts. So if AMD is redefining the economics of the data centre shouldn’t we see some “trickle-down economics” hit corporate It budgets? That’s a conversation that’s worth having between IT Directors and and their cloud providers for sure.


Outside of the cloud, hosting and SaaS, the performance levels AMD have announced mean that you can start recalibrating how you spec computers for the critical apps that are driving modernisation. From Analytics through to VDI, whether through a provider or hosted on-prem, you can start to benefit from the same performance and efficiency crammed into the 4th Gen EPYC ™.


I spoke to AMD’s Dylan Larson, Director, EPYC product management about this launch to get a better understanding of how AMD themselves are viewing it.

Dylan was keen to point out that AMD is making increasingly more effort to expand the reach of its announcements. He feels it’s important that everyone involved in the business of delivering IT has an understanding of developments with processor technology, he explains that given the cloud, SaaS and hosting options, IT managers may not always make decisions about processors but he feels they should be part of the discussion, and that starts with being kept well informed about the landscape.

Dylan confirmed that in his three years at AMD, this is the most significant announcement they have made regarding EPYC. Whilst every announcement is substantive, Dylan feels this one really does make a mark and ups the game in terms of the leap forward AMD has made against the rest of the playing field.


According to Dylan, it’s not just about the performance, this time round the major advances made in energy efficiency are massive and, in his view, makes the launch even more significant.  We know this translates to cost savings but at a time when ecological imperatives are steering corporate direction, IT teams are questioning their IaaS providers more deeply about their own green credentials, so this topic is indeed taking on more significance.

Interestingly in Dylan’s opinion, he feels like it’s a pivotal moment in his industry. He can’t remember a time when any company had such a large technical lead over the competition as AMD has today with the announcement of the 4th gen processors.

For Dylan, this comes back to outcomes, faster time to market for manufacturers, more capability to spot fraud at scale in real-time for FSIs, and HPC tasks hammered out increasingly more quickly.

Dylan’s colleague Ram Peddibhotla, VP of Product Marketing at AMD, probably nailed it when he briefed us earlier in the day and stated that companies that do not adopt this next level of processor performance and efficiency are simply going to be left behind.

Offering Unmatched Performance, Leadership Energy Efficiency and Next-Generation Architecture, AMD Brings 4th Gen AMD EPYC ™ Processors to The Modern Data Center

-New AMO EPYC™ processors are the world’s fastest and most energy efficient, allowing customers to

modernize their data centers to drive actionable insights for better business results-

-AMO EPYC™ processors are supported by a complete cloud, enterprise, hardware and software


SANTA CLARA, Calif. – November 10, 2022 -Today, at the “together we

advance_data centers” event, AMO (NASDAQ: AMO) announced the general availability of the

4th Gen AMO EPYC™ processors; with unmatched performance for critical workloads across

cloud;, enterprise;; and high performance computing;;;_

The 4th Gen AMO EPYC processors bring next-generation architecture, technology, and features to the modern data center. Built on the “Zen 4” core, the highest performance core ever

from AMDiv, the processors deliver leadership performance, energy efficiencyv and help customers accelerate data center modernization for greater application throughput and more actionable insights.

“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.”


Accelerating Results and Driving Actionable Insights for Businesses


4th Gen AMO EPYC processors are designed to deliver optimizations across market

segments and applications, while helping businesses free data center resources to create additional workload processing and accelerate output.

With 4th Gen AMO EPYC processors, businesses can:

  • Support Performance and Efficiency. With up to 96 cores in a single processor, the new AMO 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, AMO continues to deliver enhanced security features in x86 CPUs. The 4th Gen AMO EPYC processor series expands on AMO Infinity Guardvi, 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 AMO EPYC processor introduces support for DDR5 memory and PCle® Gen 5, which are critical for Al and ML applications. In addition, 4th Gen AMO EPYC processors support CXL ® 1.1 + for memory expansion, helping customers to meet demands for larger in-memory workload capacity.

All of these features and capabilities ultimately enable customers to use the 4th Gen EPYC processors to drive infrastructure consolidation with similar or better performance; thereby helping reduce the costs and energy consumption of their data center.
