Two Intel Cascade Lake-X processors which are part of the HEDT X299 platform have leaked out in Geekbench database (via Momomo_Us). The processors include an 18 core part and a 10 core part, both of which would be based on a heavily optimized 14nm process to deliver better performance.

Both processors seem to be leaked by Dell who tested them with their Precision 5820 X-Series PCs. The Precision 5820 Tower is a high-end workstation PC that currently supports 9th Gen Core-X and Xeon W-2000 series processors on the LGA 2066 socket. Since the Precision 5820 is being used to test the upcoming HEDT processors, we can tell that those would be supported by Intel’s LGA 2066 socket too. The processors are identified as GenuineIntel Family 6 Model 85 Stepping 7 confirming that these are indeed Cascade Lake-based parts and not Skylake-X designs that we have seen with 7th and 9th Gen HEDT processors.
