AMD outsells Intel in the datacenter space

Interpretation notes: first time, in the era during which said companies broke out "datacenter" as a reporting category. The last time AMD was clearly on top in terms of product quality, they reported 2006 revenue of $5.3 billion for microprocessors while Intel reported $9.2 billion in the same category. In those years the companies incompletely or inconsistently reported separate sales for "server" or "enterprise".

Still, there were always clearly defined product lines, like Athlon vs. Opteron.

Yes, but not differentiated in the earnings reports.
