12 core Intel Core i9-10920X edges the AMD Ryzen 9 3900X in Geekbench; scores 22% more than the Threadripper 2920X in multicore workloads too but at likely 3x the price

Yet more of the Cascade Lake-X product stack has appeared on Geekbench, with someone now testing the successor to the Core i9-9920X. The processor in question looks to be an engineering sample based on the clock speeds that Geekbench reports, but the 12 core and 24 thread CPU can already match the AMD Ryzen 9 3900X and outscore the Threadripper 2920X by up to 22% in multicore workloads. Albeit, the Core i9-10920X will probably cost up to 3x the price of comparable AMD chips.

Another week, another Cascade Lake-X (CL-X) related leak. We have already reported on the Core i9-10980XE and Core i9-10900X appearing on Geekbench in a Dell Precision 5820 Tower X-Series desktop, and now the Core i9-10920X has done the same. The 12 core and Hyper-Threaded processor identifies as a GenuineIntel Family 6 Model 85 Stepping 7, the same identifier used for all previous CL-X SKUs that have appeared online.

Geekbench reports that the Core i9-10920X has a Skylake-X 07 northbridge and an X299 southbridge, the same chipset reported in previous CL-X leaks. The CPU clocked between 2.77 and 3.8 GHz, which is rather low for an Intel High-End Desktop (HEDT) processor. By contrast, the Core i9-9920X has a 3.5 GHz base clock and can boost up to 4.4 GHz, suggesting that we are looking at a Core i9-10920X engineering sample. Hence, we expect retail units to have higher clock speeds than the Core i9-10920X on show here. A recent tip by @momomo_US corroborates this, with it stating that Core i9-10920X retail units will have a 3.5 GHz base clock like the Core i9-9920X.

While the performance of this engineering sample probably does not reflect what retail versions will achieve, it already outperforms both the AMD Ryzen 9 3900X and Threadripper 2920X in the multi-core benchmark. The latter falls around 22% short of the Core i9-10920X according to our database, although we expect its Zen 2 successor to make strikes in multicore performance.

However, Intel HEDT processors are significantly more expensive than their AMD counterparts. Intel prices the Core i9-9920X at between US$1,189 and US$1,199 for bulk orderers, for example, so we expect the company to price the Core i9-10920X similarly. By contrast, the Threadripper 2920X currently sells for US$373.48 on Amazon.com, with a US$649 list price. So, while the Threadripper 2920X and Core i9-10920X are both 12 core HEDT chips, the latter will likely cost almost three times as much as the former. By current estimates then, the Core i9-10920X will offer better performance, but comparable Threadripper processors will be leagues better value for money.
