2nd Gen EPYC – Everything You Need To Know Summarised!

Leveraging their new Zen 2 microarchitecture and 7 nm process technology, AMD just introduced their 2nd Gen EPYC processors.

Designed to challenge Intel Xeon in the enterprise, cloud and HPC markets, the 2nd Gen EPYC processors promise to deliver “record-setting performance“, while reducing TCO (Total Cost of Ownership) by up to 50%.

Here is everything you need to know about the new 2nd Gen EPYC processors… summarised!

2nd Gen EPYC - Everything You Need To Know!

 

The Official 2nd Gen EPYC Product Presentation Summary

Let’s start with a quick 7.5 minute summary of the 2nd Gen EPYC product presentations by Dr. Lisa Su, Mark Papermaster and Forrest Norrod!

Now, let’s take a look at its key features and specifications!

AMD Infinity Architecture Explained

The AMD Infinity Architecture is a fancy name for their new modular chiplet-based design. It allows them to combine up to eight processor dies with a single I/O die on the same package, faster and at lower cost.

The processor dies are fabricated with the industry-leading 7 nm process technology for best performance at lowest power consumption, and thermal output.

The I/O die, on the other hand, can be fabricated on the much cheaper 14 nm process technology, with a much higher yield.

2nd Gen EPYC Is Built On 7nm

The 2nd Gen EPYC processor cores are fabricated on the 7nm process technology. This allows AMD to fit more transistors into a smaller space.

By doubling the transistor density, coupled with microarchitectural optimisations, the 2nd Gen EPYC delivers 4X the floating point performance of the 1st Gen EPYC processors.AMD 7nm EPYC processor die

The smaller process also increases energy efficiency, reducing both power consumption and heat output. According to AMD, 2nd Gen EPYC will use half the power consumption as the 1st Gen EPYC at the same performance level.

Industry-Leading Performance

AMD claims they will offer up to 90% better integer performance and up to 79% better floating-point performance, than the competing Intel Xeon Platinum 8280 processor.

On top of significantly better performance per socket, they also come with hardware memory encryption, and a dedicated security processor.

Baked-In Security On Multiple Levels

The 2nd Gen EPYC processors are built-in with multiple levels of security features, to harden it against cyberattacks.

  • They have a secure root of trust designed to validate the initial BIOS boot without corruption.
    In virtualised environments, you can use it to cryptographically check that your entire software stack is booted without corruption.
  • They have memory encryption engines built into their memory channels to hardware-encrypt data in the memory, preventing cold boot attacks.
  • In the 2nd Gen EPYC, every virtual machine is now encrypted with one of up to 509 unique encryption keys known only to the processor.
    This protects your data even if a malicious VM finds its way into your virtual machine memory, or if a compromised hypervisor gains access into a guest VM.

2nd Gen EPYC Is PCI Express Gen 4 Ready!

Like the 3rd Gen Ryzen processors, the 2nd Gen EPYC is PCI Express Gen 4 ready.

PCIe 4.0 doubles the bandwidth over PCIe 3.0, and every EPYC processor has 128 lanes to tie together HPC clusters, or connect to GPU accelerators and NVMe drives.

2nd Gen EPYC Is Already Changing The Industry

AMD appeared to have shipped the 2nd Gen EPYC processors early to Google, where they were deployed in production servers for their internal datacenter infrastructure.

Google also plans to use the 2nd Gen EPYC processors in new general-purpose machines that are part of the Google Cloud Compute Engine.

Twitter has also announced that they are already using the 2nd Gen EPYC processors to reduce their datacenter TCO (total cost of ownership) by 25%.
