AMD has taken the wraps off its 4th Gen EPYC processors built for critical workloads in the cloud (opens in new tab)enterprise and high performance computing (HPC).
AMD, unveiled at an event in San Francisco, says the launch will drive greater energy efficiency and help its customers accelerate the process of data center modernization.
The AMD Zen 4 series is divided into three families, the standard Zen 4 for EPYC Genoa, the Compute Density-Optimized Zen 4C for EPYC Bergamo and the Cache-Optimized Zen 4 V-Cache within the EPYC Genoa-X series.
4th generation EPYC
With up to 96 cores in a single processor, AMD claims its new EPYC lineup should allow its customers to deploy fewer but more powerful servers to meet individual computing needs, which in turn will apparently push more flexibility within the data center.
The 4th generation data center fabric technology takes a more holistic approach to simplify and scale connectivity as well as the full set of infrastructure services.
Ram Peddibhotla, Corporate VP EPYC product management, said: TechRadar Pro that the qualities of the 4th generation EPYC that make it the best performing server processor come in three parts, starting at the core.
“We have been on a journey to improve our core and with Zen 4 we have very strong cores. They are coupled to 5nm process nodes – that combination delivers very good performance at the socket level and at the pro core level,” he says.
“We’ve packed enough of those cores into a package so that we can deliver 96 cores in a package. When you have that many strong cores, it delivers phenomenal performance. The third quality is its energy efficiency. We don’t just look at the performance itself, we look at the power consumption.”
AMD is confident that these processors will help bridge the gap between companies that meet their sustainability goals and generate real dividends.
Peddibhotla goes further, saying that his customers can save very tangible amounts of power consumption and reduce energy costs by using EPYC.
“In a very typical scenario, if you have 15 servers from Intel, (opens in new tab) that are deployed, rather than deploying those, you could get the same performance by deploying five EPYC servers – that consumes less than half the power,” he continues.
“This translates directly into energy savings and sustainability benefits because there is a carbon footprint associated with this energy that is produced. In this example of 15 vs. five, the difference between the two sides is 25 tons of carbon dioxide. That’s equivalent to what 30 acres of American forest can remove from the atmosphere.”
The Zen 4 solution features up to 12 CCDs, 96 cores, and 192 threads, and each CCD comes with 32MB of L3 cache and 1MB of L2 cache per core (Zen 3 offers 512KB per core).
“There are many challenges that data center administrators are trying to solve, and EPYC is a very attractive solution for data center administrators for performance in general, whether it’s how many things a data center administrator tries to do or how quickly it tries to get things done. get,” added Peddibhotla.
“It’s also a good answer for footprint – you can get a lot more for a given rack, and that’s incredibly valuable for a data center. If you think about how many racks can fit in a data center, we can get twice the performance.” out of those racks, which would be the equivalent of building another data center — but for free.”
Available on premise or in the cloud, the 4th Gen AMD EPYC processor series extends on AMD Infinity Guard, a suite of features that provides physical and virtual layers of protection. In addition, AMD doubled the number of encryption keys compared to previous generations to help its customers keep data safe when stored in the cloud or in storage.
