My hunch is that it is not actually a new SKU. Instead, it's likely either an engineering sample leading up to the launch of the Ryzen 9 3950X, or misrepresented specs. I won't rule it out entirely, though. If the specs are indeed accurate, it would fall just under the Ryzen 9 3950X in the pecking order with a base clock that is 200MHz slower, and whatever the non-oveclocked boost clock settles at.
The Core i9-9980XE is a monster Skylake-X processor with 18 cores and 36 threads clocked at 3GHz to 4.5GHz. You can see its scores in the left column, while the 16-core/32-thread Ryzen processor is represented in the right column.
AMD's chip wins in both rounds— single-core and multi-core performance. Both victories are impressive in their own right, the former because it speaks to closing the IPC gap, and the latter because AMD is working with two fewer cores and four fewer threads. And of course there is the pricing. The Core i9-9980XE is a $1,999 processor, while the Ryzen 9 3950X is set to debut at $749. Even if the Ryzen processor in this database entry is a different SKU, pricing is likely to be similar.
The one thing that should temper enthusiasm here is not knowing what type of cooling was used for this benchmark run. Hitting 5.2GHz on all 16 cores is impressive for sure, but whether or not that will be the norm remains to be seen. We'll find out soon enough, though—AMD's third-generation Ryzen lineup will be available starting July 7.
