With every launch of a new architecture, Intel likes to release a set of enthusiast parts that typically hit the market a year after the standard-grade SKUs. Recently, for example, we saw the launch of the Haswell-E line-up around a year after the first Haswell parts landed.
Intel is gearing up to launch Broadwell at the end of this year (at least for mobile products), so it was only natural to see many leaked roadmaps place Broadwell-E's launch at the end of 2015. However, according to the latest rumor from VR-Zone, Intel has delayed the enthusiast grade parts until 2016, with sampling set to occur in the second quarter of 2015.
According to their sources, Broadwell-E will pack similar hardware to Haswell-E. This means we'll get up to eight physical cores, 40 PCIe lanes, up to 20 MB of cache, and support for quad-channel DDR4-2400. One main difference is the switch to a 14nm process node, although the TDP of Broadwell-E will reportedly stay the same at 140W.
Intel has also allegedly entered the sampling phase for their upcoming Skylake-S desktop parts. It's expected that these CPUs will enter mass production in the second half of 2015, ready for devices in the latter part of the year.
Skylake-S parts will carry a TDP of up to 95W, according to VR-Zone. They will support both DDR4 and DDR3 memory, and current samples feature Turbo clocks up to 2.9 GHz. Skylake will require a new CPU socket, LGA 1151, meaning it won't be backwards compatible with existing Haswell motherboards.
