To further boost the performance for HPC workloads, Intel will significantly increase the memory bandwidth for all "Knights Landing" products by introducing integrated on-package memory.
Seems like Intel is getting a good amount of mileage from their eDRAM development efforts.

My personal speculation is that they will put in a 4x DDR4 socket, just like Haswell-E.
Having no need for a host CPU makes things easier on programmers and increases power efficiency as well. As a PCIe accelerator the Xeon Phi has already marked a declining trend in GPGPU, but it seems Knights Landing will raise the bar substantially for Nvidia to remain competitive.
