AMD launches new Epyc data centre CPUs


AMD has launched new 3rd Gen AMD Epyc processors that it says are the the world's first data centre CPUs using 3D die stacking.

The new Epyc CPUs also feature AMD's 3D V-Cache technology (formerly codenamed Milan-X), and deliver up to 66% more performance for certain technical computing workloads than comparable, non-stacked 3rd Gen AMD Epyc processors. They also incorporate the "industry's largest" L3 cache at 768MB.

The new processors – the 16-core 3.05HGz 7373X, 24-core 2.8GHz 7473X, 32-core 2.8GHz 7573X and 64-core 2.2GHz 7773X – are socket and software compatible with previous 3rd Gen Epyc CPUs, and include the same modern security features.

They are aimed at technical computing workloads such as computational fluid dynamics (CFD), finite element analysis (FEA), electronic design automation (EDA) and structural analysis.

According to AMD, the 7373X CPU can deliver up to 66% faster simulations on Synopsys VCS (EDA) compared to the Epyc 73F3 CPU, the 7773X averages 44% better performance on Altair Radioss simulation applications (FEA) compared to "the competition's top of stack processor, and the Epyc 7573X processor can solve an average of 88% more CFD problems per day than a "comparable competitive 32-core count processor" running Ansys CFX.7

"Building upon our momentum in the data centre as well as our history of industry-firsts, 3rd Gen AMD Epyc processors with AMD 3D V-Cache technology showcase our leadership design and packaging technology enabling us to offer the industry's first workload-tailored server processor with 3D die stacking technology," said AMD senior vice president and general manager, server business unit Dan McNamara.

"Our latest processors with AMD 3D V-Cache technology provide breakthrough performance for mission-critical technical computing workloads leading to better designed products and faster time to market."

Higher performance can mean fewer servers are needed, reducing power consumption and total cost of ownership.

Systems based on 3rd Gen AMD Epyc processors with AMD 3D V-Cache technology are available immediately from a range of vendors, including Cisco, Dell, Gigabyte, HPE, Lenovo and Supermicro.

"Server density is critical to ensure organisations, such as those in digital manufacturing or critical product design, can handle their demanding technical computing workloads while pushing performance boundaries. Integrating the 3rd Gen AMD processors with AMD 3D V-Cache technology with the Dell PowerEdge portfolio is a natural next step to drive the future of HPC and technical computing for our customers," said Dell Technologies vice president of PowerEdge, core compute and high performance computing Rajesh Pohani.

They are supported by various software providers including Altair, Ansys, Cadence, Dassault Systèmes, Siemens, and Synopsys.

"The volume of cores that Synopsys VCS runs on in the latest 3rd Gen AMD EPYC processors is massive. With the significant memory and cache required by today's compute-intensive EDA workloads, the memory efficiency at runtime with VCS isexceptional and gives us a big competitive edge. Our close collaboration with AMD continues to accelerate technology advances for our customers by empowering them to tackle verification challenges and complexity of tomorrow's SoCs," said Synopsys vice president of engineering Sandeep Mehrotra.

Microsoft Azure HBv3 virtual machines (VMs) have been fully upgraded to 3rd Gen AMD Epyc with AMD 3D V-Cache technology.

Thoughtworks presents XConf Australia, back in-person in three cities, bringing together people who care deeply about software and its impact on the world.

In its fifth year, XConf is our annual technology event created by technologists for technologists.

Participate in a robust agenda of talks as local thought leaders and Thoughtworks technologists share first-hand experiences and exchange new ways to empower teams, deliver quality software and drive innovation for responsible tech.

Explore how at Thoughtworks, we are making tech better, together.

Tickets are now available and all proceeds will be donated to Indigitek, a not-for-profit organisation that aims to create technology employment pathways for First Nations Peoples.

It's all about Webinars.

Marketing budgets are now focused on Webinars combined with Lead Generation.

If you wish to promote a Webinar we recommend at least a 3 to 4 week campaign prior to your event.

The iTWire campaign will include extensive adverts on our News Site itwire.com and prominent Newsletter promotion https://itwire.com/itwire-update.html and Promotional News & Editorial. Plus a video interview of the key speaker on iTWire TV https://www.youtube.com/c/iTWireTV/videos which will be used in Promotional Posts on the iTWire Home Page.

Now we are coming out of Lockdown iTWire will be focussed to assisting with your webinars and campaigns and assistance via part payments and extended terms, a Webinar Business Booster Pack and other supportive programs. We can also create your adverts and written content plus coordinate your video interview.

We look forward to discussing your campaign goals with you. Please click the button below.
