Not an "expert" so some of the terms might be wrong... but the overall
differences are accurate.
The way the instruction pipelining in the processor works is different.
The Atom is closer to the Pentium processor than to the Core architecture
used in other current processors.
So code that is compiled with compiler flags optimised for one won't run
as efficiently on the other.
So the binaries in the netbook remix are built with flags optimised for the
Atom/Pentium processor whereas the stock Ubuntu is built with flags optimised
for the current generation processors.
And it's not 4-processor cores, it's just a dual-core CPU, the two extra
cores you are seeing are HT cores which allow multiple threads/processes to
send instructions to the CPU simultaniously, and the processor will execute
them whenever possible.
