In Power Producer, a single Xeon runs at 40 per cent and dual Xeons run at 20 per cent load. The performance of Core i7 and the Xeons in these games and apps comfortably beat Skulltrail which is doubtless due to a combination of factors. The QX9775 CPUs in Skulltrail support SSE 4.1 whereas Core i7 and Xeon 5500 support SSE 4.2, and Skulltrail suffers from its use of 800MHz FB-DIMM memory.
