Core i7-4810MQ or Core i7-6820HQ?
Personally I would go with the Core i7-6820HQ.
Have a look at these comparisons.
The only real way to test them for SolidWorks, is to run the SolidWorks performance test.
Thanks Matt. That link seems to indicate that the 4810 is actually faster than 6820.
This is actually why I asked the question. Unfortunately I cannot test the two CPUs with SW before buying the workstation.
Just a gentle bump.
I use PassMark Software - CPU Benchmark Charts to compare CPU performance, especially when it is a matter of computations.
Keep in mind though that some new CPUs have very small number of published results and it may not be very accurate.
Note also that new CPU or higher Clock frequency does not necessarily mean faster CPU. When you compare multi-core single CPU or Dual/Quad CPUs you have to do apples-to apples (same cores/ same number of CPUs). Definitely more cores means more parallel runs can complete for a clock time closer to the completion time of a single run. However, if a single runs is benchmarked an old CPU with less cores could be faster than a new CPU with more cores or even than Dual/Quad CPUs. This is because the Speed-up of Flow Simulation is not linear while increasing the number of cores. It increases linearly up to 4 cores, and then the Speed-up curve (CPU time vs. Cores) starts departure down from the linear trend, almost saturated (no speed-up) for 16 or more cores.
From a brief glance it looks like the only big change is the architecture (14nm vs 22nm) from what I understand this means more power efficient operation but not better performance (at least from a SW and Simulation standpoint). It's always nice to have new architecture especially if the 22nm format gets phased out down the road but if dollars and cents are a factor I don't see any problem with going the 4810MQ route.
Like Jesse and Boyko write, the performance difference probably is small. Personally I like the intel comparison more ARK | Compare Intel® Products, it shows the 6820HQ is capable of using DDR4 memory, which could give it an edge. Also the clock speed you will want to use is the overclocked speed, which will be throthled down when the temperature increases, the 6820 will probably perform a little better in that area.
Just in support of what I said above: A much older Dual CPU Xeon X5675 3.07MHz (2x6 cores), ranked 59th, perform the same and even better with hyper-threading ON ( normally the hyper-threading slow down the Flow Simulation) than much newer Dual Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz, 2494 MHz, (2 x 12 Cores), ranked 5th for up to two Flow Simulation runs in parallel. For more runs in parallel the number of cores are important and the second platform performs better.
Thanks for all your answers. All provided great insight and have been helpful.
