I was just reading that the Xeon D is still 5.5x faster than the AMD Opteron A1100 (which does not have significantly better TDP) so it seems like Xeon-D is where it&#x27;s at.<p><a href="http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;9956&#x2F;the-silver-lining-of-the-late-amd-opteron-a1100-arrival" rel="nofollow">http:&#x2F;&#x2F;www.anandtech.com&#x2F;show&#x2F;9956&#x2F;the-silver-lining-of-the-...</a><p>I built a home VMware server a while ago using a 4670T which has similar performance to a Xeon D but does not have ECC and tops out at 32GB. Works pretty darn well even with the multiple VMs I have running on it. I think I measured power consumption at the wall at 40+ish-55W so it&#x27;s quite efficient.
