i7 5820k or i7 6700k?

[marcopasotti]

Hi everybody I have to assembly a pc for 3d modeling, FEM and CFD calculations.
which one is preferable?
- 5820k little older, lower clock, higher bandwidth and 6 cores
- 6700k newer architecture, higher clock, lower bandwidth, 4 cores
Thank everybody in advance

5820K

6/12 cores of overclocked 5820K running quad channel DDR4 and 4.2Ghz, has significantly higher calculation throughput than anything you can do with a 4/8 core i7 6700K, even at 4.9Ghz.

The 10% architectural difference is included in the calculations.

The LGA 2011 is still a live socket, with the new Broadwell-E chips announced later this year. (End of first quarter, but possibly delayed)

All X99 motherboards are at least robust, and some are very good indeed.

I would honestly wait for skylake-E if anything

I disagree. There is always something new and wonderful over the horizon, but Skylake-E is a fair way off. Broadlake-E has yet to be released and it will run in existing x99 motherboards. If the OP actually want to build a system soon, Hawell-E and Broadwell-E (when it is released) are the only solutions.

Skylake is sufficiently similar to Haswell and Broadwell, that Skylake-E, when it comes out in 2017, is likely to be an incremental improvement, rather than an evolutionary improvement.

As for me i sitll would wait..So much buyers remorse would kick in. I see people buying 970s/980 Ti now and knowing pascal is coming out 80% they will end up selling they gpus losing out money and getting the new gpu anyways plus i like to think future wise..For me if i had the money i would still wait for skylake E..Thats just me though

But by the time that Skylake-E is here or near, in 2017, Kaby Lake-E may be only a year or so away. When does it end?

I certainly would not buy Haswell-E until Broadwell-E was out (provided it arrives on time) in the next couple of months.

In fact, I'm waiting now to see what to do with my calculation system.

That's a long time from now. Broadwell-E isn't even here yet.

I'd go with the 5820k and overclock it. It will out perform the 6700k. Also, you will be ready for Broadwell-E when it comes out in 3-4 months as Broadwell-E chips are suppose to drop right into existing X99 mobos.
