Well the comparison is because AMD will have this chip ready and out in the next month. Intel's Cascade- x response probably isn't due for at least another 3-4 months. The fabled 28 core that Intel showed off seems like it'll be a consumer product that could take on this 32 core Threadripper, but not too soon.

Secondly Intel's monolithic designs are always likely to win on a per core/thread basis, but the people buying this sort of massively threaded CPU are generally most interested in massively threaded workloads. Kind of self evident I think.

The gaming market for 28 and 32 core processors doesn't exist, any small disparity in gaming performance would be of little concern at this level.

It's comparing by price points.
