Several desktop OEMs have started to begin listing Intel's 5th generation Core Broadwell CPUs and the latest set of slides, including new Intel roadmap suggest that 6th generation Core Skylake CPUs should be available in Q3 2015.

The new roadmap, leaked by PCOnline.com.cn shows that Intel 5th generation Core Broadwell CPUs are incoming and will include two parts, Intel Core i7-5775C and the Core i5-5675C, both based on 14nm manufacturing process, LGA1150 socket, unlocked multipliers and compatible with Intel's 9-series chipset motherboards.

While it is obvious from the roadmap that the Core i7-5775C and the Core i5-5675C are not direct replacement of the Core i7-4790K and the Core i5-4690K, since these are placed in different product tiers. While the Core i7-4790K was P1K tier, Broadwell-based Core i7-5775C will be a part of the new P1+ tier. The same story goes for the Core i5-5675C, which is a part of MS2+ tier and not a direct successor of the Core i5-4690K.

Both the Core i7-5775C and the Core i5-5675C are quad-core SKUs with 65W TDP and pack Intel Iris Pro 6200 graphics part with 48 EUs and support for DirectX 11.2. The Core i7-5775C has support for Hyper-threading, packs 6MB of cache and works at 3.3GHz base and 3.7GHz Turbo clocks. The Core i5-5675C on the other hand lacks support for Intel Hyper-threading, has 4MB of cache and works at 3.1GHz base and 3.6GHz Turbo clocks.

Intel's 14nm 5th generation Broadwell architecture is practically an optical shrink of 22nm Haswell architecture, so while you should not expect any performance miracles or architecture changes, 14nm manufacturing process will bring a lot of power efficiency improvements as well as better integrated graphics, since Iris Pro 6200 packs 128MB eDRAM L4 cache.

Intel's 14nm 5th generation Core Broadwell lineup will also include the Core i7-5775R, Core i5-5675R and the Core i5-5575R SKUs, all three with 65W TDP, lack of unlocked multiplier and same Intel Iris Pro 6200 IGP.




The leaked slide also shows that the 14nm Broadwell Core i7-5775C and the Core i5-5675C will be a brief novelty on the market as Intel plans to introduce its 6th generation Core Skylake-S desktop parts as early as Q3 2015. The new 14nm Skylake architecture will feature new LGA1151 package and will come with the new Intel 100-series chipsets.

Unlike unlocked Broadwell SKUs, the new Skylake-S SKUs will be a direct successor of the Core i7-4790K and the Core i5-4690K. These two Skylake SKUs that are most important are the Core i7-6700K and the Core i5-6600K. The Core i7-6700K is a unlocked quad-core part with 8MB of cache and support for Hyper-threading, working at 4.0GHz base and 4.2GHz Turbo clocks, while the Core i5-6600K is also a quad-core part with 6MB of cache, lack Hyper-threading support and works at 3.5GHz base and 3.9GHz Turbo clocks.

Intel's 14nm Skylake lineup will have plenty of other SKUs including the Core i7-6700 and Core i5-6600, which will lack unlocked multiplier have lower clocks but also lower 65W TDP. The third group of Skylake chips will be low-power 35W TDP parts.




Enthusiasts will also look forward to Intel's Z170 Express chipset motherboard that will support both DDR3 and DDR4 memory.

In any case, it will be an interesting year, at least when it comes to Intel CPUs as we will see two new architectures in the same year, 14nm Broadwell and 14nm Skylake architectures.
