AMD EPYC Infinity Fabric V Intel Skylake SP Architecture Deep Dive

After our AMD EPYC v. Intel Broadwell-EP (Xeon E5 V4) video, we wanted to provide an in-depth architecture deep dive using the new entry. Today, we have our AMD EPYC and Intel Xeon Scalable Architecture Deep Dive video. While we normally focus on our website having all of the information, it is a very technical subject. We tried to up-level the discussion and put it into a YouTube format that you can watch. e7-4870 v2

AMD EPYC and Intel Xeon Scalable Architecture Ultimate Deep Dive

In the overall technology publishing sector today, there is an incredible amount of fear, uncertainty, and doubt (FUD) being generated by both Intel and AMD marketing. Some of the technical descriptions we have read via links forwarded to gaming sites are appallingly bad to the point where they are untrue. For example:

  • Dual-socket Intel Scalable systems can use up to 128 PCIe lanes and have more effective PCIe lanes than AMD EPYC in a specific use case.
  • AMD EPYC Infinity Fabric, in a dual socket GPU system, needs to not just handle memory bandwidth but is also needs to be able to handle GPU-to-GPU or GPU to NIC bandwidth (e.g with NVIDIA GPU direct) in addition to memory transfers.

Intel and AMD both invest time to ensure STH is one of the resources on the Internet with a solid foundational understanding of server architectures since that is what we specialize in. As such, we wanted to do an in-depth architecture overview so that our readers can have intelligent discussions with their colleagues, customers, and vendors. We did up-level the discussion so that it is accessible to a broader audience.

AMD EPYC Infinity Fabric V Intel Skylake SP Objectives

Here is the video:


Although it is, by far, our longest video to date, it has just about every bit of information you will need to understand the basics of AMD EPYC v. Intel Scalable in dual socket configurations. Further, we do show why Intel Scalable Mesh Interconnect Architecture is an important differentiator over the Intel Xeon E5-2600 V4 series (and V1 through V3 for that matter.)

We have in-depth written articles about the new Intel Xeon Scalable architecture that you can find at our Intel Xeon Scalable Processor Family (Skylake-SP) Launch Coverage Central. We also have a series on AMD EPYC such as our AMD EPYC 7000 Series Architecture Overview for Non-CE or EE Majors piece. Please do your part to reduce FUD in the market by sharing these resources.
