Dell Precision 3930 Performance
In terms of performance, our Precision 3930 was very close to our Xeon E-2146G in our original review. As such, we thought it was worthwhile showing the other CPUs we have tested just to give some sense of the range of what one can configure in this system. Of course, you can go to the original CPU reviews to see how these compare to other platforms. Instead, we wanted to show relative performance since there are a lot of configuration options. Here is our Linux kernel compile benchmark:
Here is the 7zip compression:
Here is our OpenSSL sign:
Here is the OpenSSL verify:
The key takeaway here is the same as when we did the initial reviews. The big performance deltas are really found when scaling cores/ threads in this line, not when going up a minor SKU bump. That is why the Xeon E-2146 we called our top value pick in the Xeon E-2100 generation. Of course, if you have a Quadro RTX 4000 or something configured and lots of memory and storage, moving up CPU levels is a relatively small cost and may be worthwhile. Moving up CPU tiers also means something else in this system, the Microsoft tax.
Microsoft Windows Pro for Workstations Tax
One item that we need to mention is the impact of this being a Windows Pro for Workstations line. Microsoft makes Xeon workstations, even at the low-end like this, sell with Windows Pro for Workstations or Windows for Workstations. The Intel Core equipped systems can use Windows 10 Pro (or 11 Pro). If one configures a Xeon, the price is fairly similar for the hardware, ECC support is added, but the Microsoft license needs to change.
As one can see, for the four core models, there is a ~$48 increase, for six-core models, like what we have, it is over $100. For 8-core models, this is over $150 more. One gets features like SMB direct, but that needs a RDMA NIC and supporting infrastructure. One gets PMem support with the Windows version, but the Xeon E platform does not support NVDIMMs or Optane PMem. One can use ReFS, but that is still not the most used solution. Overall, there is not much one gets as a benefit, so this is basically just a tax that Microsoft and its OEM partners levy on Xeon systems. Again, this system with the Intel Core CPUs with the same features other than ECC UDIMM support does not need this special Windows version.
Next, let us get to power consumption then on to our final words.
