There's good news and bad news for those of you wanting to purchase a socketed Intel processor with high-end integrated graphics. Let's start with the bad news.
As has been reported earlier and now confirmed by Intel, there are no plans to produce a socketed Skylake CPU with eDRAM. This essentially means there will be no flagship Skylake part for desktops with high-end Iris or Iris Pro integrated graphics, as both of these GPU families use eDRAM in Skylake SKUs.
eDRAM acts as L4 cache for the CPU and GPU, improving the performance of both. The extra cache is mostly beneficial when gaming on integrated graphics, but it can boost performance in other situations.
Intel will ship mobile CPUs in the near future with Iris Pro (GT3e/GT4e) graphics and 128 MB of eDRAM as part of the Skylake-H line, while Iris graphics and 64 MB of eDRAM are currently available in some mobile Skylake-U parts. On the desktop, however, Broadwell will remain the flagship part for integrated graphics until Intel launches a new line of CPUs.
The good news is that, contrary to some reports, Intel are not discontinuing their socketed Broadwell processors. The Core i7-5775C and i5-5675C only launched three months ago, and they will continue to be available for system builders wanting a high-end part with powerful integrated graphics.
