Intel Core i7-6950X Processor Review – 10-core Broadwell-E Benchmarked

Euler3d CFD Benchmark

Next up is the STARS Euler3d CFD benchmark. The benchmark is intended to provide information about the relative speed of different processor, operating system, and compiler combinations for a multi-threaded, floating point, computationally intensive CFD code. The benchmark test case is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45 degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes.

The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. The Intel Fortran compiler (ifort 10.0) is used and all floating point variables are Fortran’s double precision (8 bytes). Parallelization is through OpenMP. The benchmark score is reported as a CFD cycle frequency in Hertz and that is what we used to make out chart.

Benchmark Results: We arranged these benchmark results differently this time and instead of arranging them by the highest overall score (giving the most threaded processors the lead) we arranged them by single threaded performance. Once you get to 8-threads and beyond the Intel Core i7-6950X is pretty much untouchable and is in a league of its own!

    what is the max temperature 6950x can go to ? i reached 96C with it and thermal throttling option activated during the load i didnt notice that my Nepton 280L water cooling wasnt working right it ran into this degree for about 30 mins .. could this damaged the processor ?? and what is the safe temperature i can go for 6950x ?

  • Mher Hakobyan

    Can you explain me what does it mean when on the TOP of i7-6950x
    processor is written Intel confidential? and why it is written Intel
    confidential?

    I love these 6950X’s… I’m getting one! C’mon tax season, right around the corner. Silicone lottery binned 4.4Ghz 6950X here I come!

    You’d have this CPU for years, and years! And it would still be a beast! I mean look at the i7 980x 6 core, and i7 990X there like 7 or 8 years old.. and there still monsters with 12 threads! And very much a viable workstation CPU solution!

    This 6950X would cost about $4 bucks a week for 5 years. That’s about $16 a month. Well we spent the cost of this CPU on our cell phones over the period of only 1 year! And constantly upgrade them to…

    You can find them for $1399 on sale. It’s a monster!!!!

    I would love it compared it to a X5670 or X5690 or even the i7-920 OCed (I know you have one 😉 E5-1660 v1?

    All those old xeon processors can deal a good battle against all this new “super” cpus. And you can find them at a fraction of the price of the new “super” units.

    • Yian Pap

      My i7 920 OCed to 3.8Ghz achieves 4.8 score in the Euler3D benchmark. So, pretty bad compared to this CPU here, 3.5 times slower. (This is with DDR3 at 1.2Ghz). Make no mistake, this “super units” give you a lot more than old and cheap processors.

  • Wookie Groomer

    lol at that pricing… wtf.

    Why do you guys always use the AMD APUs in comparison to Intel CPUs? I know they FX processors don’t hold a candle to these newer Intel models, but at least they generally double the scores of an APU and don’t compare “AS” poorly. I guess maybe it is the test data you have available on the more recent benchmarks, but those APUs don’t have any business in an “E”-series review with benchmarks. I would leave them out. At least the magma-heat emitting 9590 could break up the blue team a little vs. the old Sandy Bridge and maybe Ivy Bridge. My old Phenom II can compete with that i7-920 better than the APUs. Just sayin’. 🙂

      I’ll be updating AMD’s offerings, but like you noted they don’t hold a candle and honestly you are the first to call me out for it. 🙂

        Thanks Nathan. 🙂 I watched the AMD Computex broadcast last night (no Stanley Cup game) 😉 and hopefully Zen breaks up the monopoly of benchmark charts.
