AMD Ryzen Threadripper 3960X, 3970X & Intel Core i9-10980XE Linux Performance  Techgage

After the embargo on the Intel Core i9 10980XE expired a few hours ago, now we are allowed to share the performance numbers on the new AMD Ryzen Threadripper 3960X and 3970X processors. These new Zen 2 HEDT CPUs pack a real performance punch, but do come in as more expensive than the i9-10980XE and there is one boot-stopping Linux bug to mention with a workaround... But besides that lone Linux support caveat, the Threadripper 3960X and Threadripper 3970X absolutely dominate in performance.

As outlined in our AMD Ryzen Threadripper 3960X / 3970X Linux review, these new Zen 2 Threadripper processors are phenomenal processors that offer significant uplift over earlier Threadripper CPUs and easily dominate over Intel's Core i9 HEDT competition. But there is one big issue right now with the Linux support: on Ubuntu and the like, it doesn't boot without a workaround. Here's that workaround for easy future reference...
