Synthetics and Scientific

In our synthetic multi-thread test, the Core i9-7960X is is enough to overtake both of the Threadripper processors from AMD and the 7980XE goes another step above that, moving into a 16% lead over the top AMD option. Taking advantage of more sophisticated AVX instructions than Threadripper has support for, the Core i9 processors take a commanding lead in the Multimedia sub-test. Raw memory bandwidth does benefit the AMD HEDT processors a bit, and they can definitely take advantage of that in some other benchmarks and workloads.
Single threaded Geekbench results on the 7980XE and the 7960X are higher than any of the AMD processors fall behind only the 7900X and Skylake/Kaby Lake mainstream CPUs. In the multi-threaded test, things are more interesting. The scores for the 7980XE and 7960X are nearly the same, with the higher core count processor just SLIGHTLY lower, interestingly. Both beat the Threadripper 1950X though even the Core i9-7900X is able to do that.
The low thread count Euler results of the Core i9-7980XE and 7960X look a lot like the 7900X, but when you hit 8 and 12 threads, they not only jump past the 7900X but leap as much as 49% faster than the AMD Threadripper 1950X.
