I replicated your setup on my PC and as I suspected having multiple CPU slots on 1 chip negatively impacts PPD.

In the first screenshot I set up 2 clients on 6700k with 4 threads each. Each client was earning 11k and 12k respectively for a total of 23k PPD.

In this screenshot I set up 1 client with all 8 threads pulling 31k PPD. Notice that the timeframe for each 1% of the work unit was halved, but the PPD was 35% more than the previous setup. This is because of the exponential PPD scale that F@H utilizes.
