The new Skylake-Us draw near, and more details come online

The new Skylake microarchitecture was launched two weeks ago at Gamescom. Following the initial Skylake-S unlocked models, the Core i7-6700K and the Core i5-6600K, Intel plans to release its next lineup for mobile computing, the Skylake U, to replace the Broadwell U.

According to Intel's roadmap, the new mobile CPUs will come in September or in Q4 2015, the company following to release 18 desktop models and at least 15 Skylake processors made for mobile solutions, that will include the high-performance "H" model, the "U" SoC and Core M chips.

No details are around regarding the "H" or the Core M models, but since the Skylake U models are getting nearer, new info about them is leaked almost every week.

A reliable source of information remains FanlessTech that brings additional information from what we knew last week regarding the new Skylake U lineup. This time we know the "Skylake-U" lineup will have 8 models that will start with the entry-level Celerons and will go up the Core i7. All the new "U" series will have two cores, will support the dual-channel DDR3/DDR4 memory controller, and will boast an integrated GPU running at 300 MHz.

Come the new Skylake U, a new DDR standard will "bless" our systems

The low-tier Celerons and Pentiums will have the HD 510 graphics, while the GPU with the "Core" ahead in their name will come with the HD 520 GPU. DRAM memory-wise, they will all support the same memory standard as all Skylakes, DDR3L and DDR4, but with lower standard frequencies reaching to max DDR4-1866. The max TDP of these new CPUs will be a very eco-friendly 15 Watt.

The Core frequencies will start with 1.6 GHz for the Celeron 3855U and up to 2.6 GHz for the Core i7-6600U. Although most of the CPUs in the new lineup have Hyper-Threading enabled, some of them will support Turbo Boost that will increase their stock clock rate up to around 800 MHz, depending on the model.

Overall the single most important improvement the new Skylakes have on the old Broadwells is the new DDR4 support. While the new chips will offer an extra 100MHz or 200MHz higher frequencies and improved integrated graphics, the memory support will ultimately make the real difference between the new-generation and the old-generation CPUs.
