Quad dual-core*. That's 4 silicon dies, each with two copies of "the core of"
a CPU. So (4 * 2) = 8 separate instruction execution units, 8 program
counters, executing up to 8 instruction streams in parallel.
The cores on one die share some infrastructure like cache and memory access,
but the interesting feature here is that this machine can run 8 threads
concurrently.

* Says the original poster. Looking at the Dell site, I reckon it's actually
dual quad-core - so two dies, 4 cores per die. Still 8 concurrent threads,
though.
