This should be the flagship SKU and it appears it won't have the 1998X model number, as previously rumored. The engineering sample works at 3.4GHz base clock and was running on an ASRock X399 Professional Gaming motherboard with 16GB of DDR4-2133 memory.
The ThreadRipper 1950X, as it is currently called, packs a massive 32MB of L3 cache and 8MB of L2 cache. Since this is an engineering sample, bear in mind that the performance figures are far from final as AMD will probably further optimize the performance and the sample was not running with lower clocked memory, with no details on the quad- or dual-channel setting.
According to the results posted on Geekbench and spotted by Wccftech.com, the ThreadRipper 1950X managed to get a 4,167 score in the single-thread benchmark and 24,539 points in multi-thread benchmark.
The CPU was compared to Intel's Xeon E5-2697A 4 CPU, which is also a 16-core/32-thread CPU based on Broadwell architecture and which scores 3,651 in single-thread and 30,450 points in multi-thread performance.
While the Xeon CPU scores higher in multi-threaded performance, it is possible that AMD's Simultaneous MultiThreading (SMT) still needs further tweaking and that final performance could be higher.
AMD is expected to launch a total of nine different Ryzen ThreadRipper SKUs although it is possible that only some of them will launch at the rumored July 27th date.
