multicore vs. max. performance per core

[Anonymous]

Hello,

I am going to buy new PCs for our institute and have the choice whether to go with a 6-core 5th gen (Haswell-E) i7 (Intel Core i7-5820K) or with a 4-core 6th gen (Skylake) i7 (Intel Core i7-6700K). 

As the system requirements state, a high speed rating is suggested, as well as many cores:

"Single- or Multi-Core Intel® Pentium®, Xeon®, or i-Series processor or AMD® equivalent with SSE2 technology. Highest affordable CPU speed rating recommended.

Autodesk® Revit® software products will use multiple cores for many tasks, using up to 16 cores for near-photorealistic rendering operations."

We normally do not render a lot, so my question is if I am right to choose the 6700K, whose performance per core is better, but in total has 4 (virtual) Threads less.

Thanks a lot!

Check out a similar discussion over at AUGI forum Revit - Best Processor i7 or Xeon

See CPUBenchmark.net High End CPU Performance and CPUBenchmark.net Single Thread Performance to compare processors.

i7-4790K is our current CPU of choice for tops in single thread performance where Revit mainly lives during modeling (Which function in Revit will take use of multiple processors ). We'll keep evaluating multi-thread each year as Revit continues to utlize them more and more.
