The new Geekbench include 6-core / 12-thread and 10-core / 20-thread models from the upcoming Comet Lake-S with relatively low boost clocks. They also pack the UHD Graphics 630 iGPU, so no Xe architecture that could boost the graphics performance. Hopefully the 10-core model is not the-top-of-the-line for Intel's gen 10 desktop CPUs as they would not stand a chance against AMD's upcoming Zen3 chips.

Intel's integrated graphics take up significant die space for not a lot of performance, I suspect Xe takes up even more die space so they let it go for the yield.
