In the current Xeon E-2100 realm, the Intel Xeon E-2186G is the current top SKU. Featuring six cores and twelve threads, the CPU’s value proposition is simple: it has six high-speed cores and the TDP headroom to push those cores at high clock speeds. With this generation of six-core CPUs, and while maintaining similar clock speeds as the E3-1200 V6 generation, means that one gets significantly more performance. These chips are popular in the low power tower server segment along with segments like dedicated servers as we saw in our HPE ProLiant DL20 Gen10 Review and Supermicro SYS-5019C-MR Review. In this segment, the Intel Xeon E-2186G now has 50% more cores than the previous generation which means those upgrading will see the largest performance boost in almost a decade. See our Looking back at Intel Xeon E3-1200 V1-V6 to the New Xeon E-2100 to learn more about how these chips are truly something new.

Key stats for the Intel Xeon E-2186G: 6 cores / 12 threads and 3.8GHz base clock and 4.7GHz turbo boost with 12MB cache. The CPU features a 95W TDP. This is a $450 list price part which is very reasonable for this level of performance in today’s market. It is also the same price as the previous generation Intel Xeon E3-1285 V6. Here is the ARK page with the feature set.

Here is what the lscpu output looks like for the chips:

Test Configuration

Here is our basic configuration for this class of CPU:

  • Motherboard: Supemicro X11SCA-F
  • CPU: Intel Xeon E-2186G
  • RAM: 4x 8GB DDR4-2666 ECC UDIMMs
  • SSD: Intel DC S3710 400GB
  • SATADOM: Supermicro 32GB SATADOM

The CPU itself supports up to 64GB of RAM, in a 4x 16GB configuration, today. Intel specs say that as 32GB ECC UDIMM modules become available, the CPUs will support 128GB in 4x32GB configurations. We see these platforms using 32GB or less given cost sensitivities.

There are going to be folks who want to point to AMD alternatives. As of this writing, there are really no alternatives in this space because while AMD may have competitive CPU parts, vendors have a vibrant Intel Xeon E-2100/ Core i3 ecosystem. AMD needs to do some work here to catch up, but it is not a focus market for them. Single socket servers in this segment are a relatively low volume area.

Next, we are going to take a look at our Intel Xeon E-2186G benchmarks, we are then going to focus on power consumption then conclude with our final words on the processors.


  1. Pugetsystems released a few articles about GROMACS with the following conclusion: With a RTX2080ti your results will be 10x better than with only a CPU.

  2. 2nd paper lunch. Most of the CPUs from E-2xxx is not available throughout Europe. Have been waiting for one since the beginning of a November They are saying we should get one in the 2nd week of January

  3. I was able to get an e-2176G from Tiger Direct and they are showing the e-2186G in stock. I woudl check there Miha if you want to deal with the shipping.
