With Intel offering CPUs that include up to 18 cores, is it easier to justify ignoring dual cpu options? In particular the new Xeon W-2145 has 8 cores and 16 threads and still turbos up to 4.5GHz for single threaded tasks.
It is nice to offer all options but sometimes there are practical limits. We can't choose both a Lenovo P520 and a P720, if we chose the P720 because a few people want the dual CPU then we have to skimp elsewhere, so perhaps the P520 with a single CPU is the better option if the people who demand dual CPUs could be satisfied with an 8-core single CPU?
