Part 2: ANSYS FLUENT Performance Comparison: AMD Opteron vs. Intel XEON

AMD Opteron 6308, INTEL XEON e5-2690 & INTEL XEON e5-2667V2 Comparison using ANSYS FLUENT 14.5.7

Note: The information and data contained in this article was complied and generated on September 12, 2013 by PADT, Inc. on CUBE HVPC hardware using FLUEN 14.5.7.  Please remember that hardware and software change with new releases and you should always try to run your own benchmarks, on your own typical problems, to understand how performance will impact you. By David Mastel Due to the response to the original article on this subject,  I thought it would be good to do a quick follow-up using one of our latest CUBE HVPC builds. Again, the ANSYS Fluent standard benchmarks were used in garnering the stats on this dual socket INTEL XEON e5-2667V2 configuration. CUBE HVPC Test configurations (Same as in last comparison)

  • Reacting Flow with Eddy Dissipation Model (eddy_417k)
  • Single-stage Turbomachinery Flow (turbo_500k)
  • External Flow Over an Aircraft Wing (aircraft_2m)
  • External Flow Over a Passenger Sedan (sedan_4m)
  • External Flow Over a Truck Body with a Polyhedral Mesh (truck_poly_14m)
  • External Flow Over a Truck Body 14m (truck_14m)
Here are the results for all three machines, total and average time: Intel-AMD-Flunet-Part2-Chart1Intel-AMD-Flunet-Part2-Chart2  

Summary: Are you sure? Part 2

So I didn’t have to have the “Are you sure?” question with Eric this time and I didn’t bother triple checking the results because indeed, the Ivy Bridge-EP Socket 2011 is one fast CPU! That combined with a 0.022 micron manufacturing process  the data speaks for itself. For example, lets re-dig into the data for the External Flow Over a Truck Body with a Polyhedral Mesh (truck_poly_14m) benchmark and see what we find: Intel-AMD-FLUENT-Details                       Intel-AMD-FLUENT-summary                      

Current Pricing of INTEL® and AMD® CPU’s

Here is the up to the minute pricing for each CPU’s. I took these prices off of NewEgg and IngramMicro’s website. The date of the monetary values was captured on October 4, 2013. Note AMD’s price per CPU went up and the INTEL XEON e5-2690 went down. Again, these prices based on today’s pricing, October 4, 2013.

We call this concept High Value Performance Computing, or HVPC. These systems have allowed PADT and our customers to carry out larger simulations, with greater accuracy, in less time, at a lower cost than name-brand solutions. This leaves you more cash to buy more hardware or software. Let CUBE HVPC by PADT, Inc. quote you a configuration today!

    Will you also write a Part 3 also now that xeons E5 v3 are out?

    What about quad socket intel setups, you also do those? It would be interesting to see if E5 4600v2 an E7-4xxx v2 are worth the money …

    Also Numascale could be an interesting option, ask them for access to their test system.
