E5-1620 v3 vs E5-2620 v3


You might have noticed that bodHOST offers two special servers based on these two processors at very competitive price range along with a complete management solution that you will hardly find elsewhere. Anyway, this is not the primary point of today’s our discussion. What we are going to see is, head to head comparison between these two members in the same family, as many still get confused when it comes to the selection, as both are popular and unique features.

So let’s start the comparison!

Advantages of E5-1620 v3

  1. With this series you get a higher operating frequency that helps to achieve better performance for mission critical applications.
  2. The best part is its CPU that supports faster memory with 2133 MHz data rate. That means you get more memory bandwidth which is advantageous for your memory bound programs.
  3. You will also notice performance gains for your applications, which are not memory bound.
  4. In addition, the price of the processor is comparatively less than the price of E5-2620 v3 Microprocessor.

Advantages of E5-2620 v3

  1. With this server, you normally immediately experience the best in performance and in memory bandwidth. In addition, E5-2620 V3 processor can be paired with another CPU in dual-socket systems.
  2. The E5-2620 v3 offers more processing cores than E5-1620 V3. Having large numbers of cores this microprocessor is able to manage multiple processors or heavy multi-threaded tasks.
  3. Furthermore, the E5-2620 CPU is also better in terms of power consumption.

Specifications, Comparison

To show the difference between these two, the most important part is to check their characteristics as well as instructions per cycle (in-short IPC) number that will help you to figure out their performance.

In specifications comparison, we will see “number of cores / threads”, Hyper-Threading technology, operating frequency + extra frequency provided by turbo feature, on-chip L2 cache and L3 cache. For information, the L3 Cache is usually larger than the on-chip L2 cache, but it’s quite on the slow side.

--run Run the script.

You must include the --run option.

--helpDisplay the help information
--revertRevert the system to the previous version and configuration.
--skip_convertDo not convert and install the EasyApache 3 profile. This flag installs the EasyApache 4 cPanel Default Profile unless you use the --install_profile flag.
--install_profileDo not convert EasyApache 3 profile. Instead, install the specified profile.

/scripts/migrate_ea3_to_ea4 --run --install_profile /path/to/profile

--convert_failWhen EasyApache 3 profile is converted to EasyApache 4 profile; this flag prevents execution of the tool’s error-correction code.

This may cause a failure when you provision your system. However, you may wish to use this flag for tests.

-y | --y | -yes | --yesAnswer yes to all of the script’s yes-or-no questions.
--forceWhen you add the --force argument to the --run or --revert arguments, the system ignores the protection checks in the place.

This may cause a failure when you provision your system.

--reinstallYum attempts to install the required EasyApache 4 RPMs and attempts to reinstall any currently-installed EasyApache 4 packages.

Supported technologies in both:

  1. Hyper-Threading
  2. PowerNow! / Enhanced SpeedStep
  3. Trusted Execution
  4. Turbo Core / Turbo Boost
  5. Virtualization
  6. Virus Protection / Execute Disable bit

Summary: Pros & Cons

E5-1620 v3:

  1. Plus points – higher clock speed, increased memory bandwidth and less expensive.
  2. Drawback – it doesn’t support dual-processing, a small number of CPU cores as well fewer threads.

E5-2620 v3:

  1. Plus points – dual-core processing, more CPU cores as well as can execute more threads at once. Also, it needs less power.
  2. Drawback: Lower operating frequency, reduced memory bandwidth priced somewhat higher.
