Intel will not offer LGA version of Skylake with eDRAM

Intel's Core i7-5775C is a somewhat unique chip, this Broadwell processor is derived from the mobile family and incorporates 128MB of eDRAM on the package with the CPU. The eDRAM acts not only as a cache for the integrated graphics but also operates as an L4 cache for the entire processor. In a recent review, The Tech Report discovered the eDRAM gives a nice performance boost even if you're using a discrete graphics card, so naturally the site wondered if Intel has any plans for desktop Skylake processors with eDRAM.

Unfortunately, it appears the answer is no, Intel has no plans for a socketed Skylake with eDRAM:

I asked this question at a briefing ahead of today's Skylake product introductions, and the answer is, sadly, no. Intel has no plans to produce a socketed Skylake derivative with eDRAM for desktop systems.

The firm didn't elaborate on the reasons behind this decision when we asked, but there has been a change in leadership. Lisa Graff, who ran Intel's desktop business for the last couple of years, has left that role, and Gregory Bryant has taken over as Corporate Vice President and GM of Desktop Client Platforms. On Graff's watch, Intel produced several unconventional products for desktop systems based on user feedback, including the Devil's Canyon K-series products, the unlocked Pentium Anniversary Edition, and the socketed desktop Broadwell parts. With Graff out, we'll have to see whether Intel continues to deliver innovative desktop products like these under Bryant's leadership.

However, there's a rumor that we may see desktop CPU with eDRAM as part of the 14nm Kaby Lake refresh in 2016. The eDRAM is definitely something to look forward to, The Tech Report mentions that in spite of a ~30W and ~500MHz handicap, the Core i7-5775C had no trouble of matching or even outperforming the Skylake-based Core i7-6700K in recent games!
