For now, the quad core version is also a 45w TDP part. There were only two launch SoCs but there are other variants coming in the next quarter or two.
Here is the Intel Xeon D-1520 page: ARK | Intel Xeon Processor D-1520 (6M Cache, 2.20 GHz)
Normally, more CPU should coming this year:Darn. I read the link from EffrafaxOfWug (here) which said 20W. Intel Ark is certainly more authoritative, so 45W it is. That's still quite good considering the dual 10GbE, etc. but not quite as impressive.
