On the subject of Multiple cores, and multiple threads, news today
shows this is advancing quite quickly. Intel does not seem to
think it is a 'waste of die area'.....
If you read what I wrote then you'd know that on a high end CPU it
takes far less area than on a low end CPU. However Intel must still
think it is a waste of die area, otherwise all their CPUs would have it...
It is required now as 8 cores on a single chip use so much
bandwidth that most cores are waiting for external memory most
of the time (despite the huge L2 and L3 caches). Switching to a
different thread on a cache miss makes sense in this case.
Eight cores and 16 threads (probably they mean per-core?) is impressive
for what sound like fairly mainstream cores.
It clearly says 2 threads per core. Any more would be a waste.
