The Intel Skylake-U lineup which is planned for launch in September 2015 has been leaked by Fanlesstech. The lineup which is based on Intel’s latest 14nm core architecture, codenamed Skylake will be available in 8 various SKUs aimed at low power notebook designs with TDPs of 15W which are configurable down to 7.5W. The new Skylake-U series will replace the existing Broadwell-U series which launched earlier this year.

Intel Core i7-6600U Leads the 14nm Skylake-U Family

According to the source, the Skylake-U family will power a range of devices from low power notebooks to Ultra books, Apple Macbook Air, entry level iMac and even NUCs (Next Unit of Computing). The Skylake-U family has a total of 8 different SKUs which will be available at different price points. These chips are featured in two SKU categories based on their I/O features. These include premium models which are all of the Core i7, Core i5 and Core i3 chips with 3 SATA 6 GB/s connections, 12 PCI-e Gen3 lanes scattered across 6 devices that may include either 10 USB 2 or 6 USB 3 ports, Intel Smart Sound Technology (12S or HDA solution, DMIC), eMMC 5.03, SDXC 3.0, Integrated Sensor Solution and support for PCI-e storage. The baseline models as the name implies cuts down on most of these features to stick to a lower cost.

Starting with the lineup, first of all we have two Core i7 chips which include the flagship Core i7-6600U and the Core i7-6500U. You will see that Intel has once again simplified their naming scheme for mobility processors which was a serious mess with Broadwell generation of processors with weird naming schemes from the desk top range to the entire mobility series. The Core i7-6600U is a dual core with hyper threading enabled, it comes with a clock speed of 2.60 GHz and has a turbo boost of 3.40 GHz (3.20 GHz across all cores). The chip features the Intel HD Graphics 520 chip with 300 MHz base and 1050 MHz boost clock while supporting both DDR4-1866 MHz and DDR3L-1600 MHz memory. This model comes in the BGA package with a TDP of 15W that can be OEM configured down to 7.5W. The Core i7-6500U has the same specifications but comes with slower clock speeds of 2.50 GHz base and 3.10 GHz boost (3.00 across all cores). Both models feature 4 MB of L3 cache.

Moving down, we have two Core i5 and a single Core i3 model which include the Core i5-6300U, Core i5-6200U and Core i3-6100U. All the models have same specifications set of dual cores with hyper threading, Intel HD Graphics 520 (300 MHz base and 1000 MHz boost), 3 MB of L3 cache, 15W TDP and 7.5W configurable TDP. The only difference is in clock speeds where the Core i5-6300U is clocked at 2.40 GHz base and 3.00 GHz boost (2.90 across all cores), Core i5-6200 runs at 2.30 GHz base and 2.80 GHz boost (2.70 GHz across all cores) while the Core i3-6100U is clocked at 2.30 GHz clock speed and doesn’t feature boost frequency.

The Pentium and Celeron lineup forms the only two base line models of the lineup with the Pentium 4405U coming with a dual core (multi-threaded) design, clocked at 2.1 GHz (no boost clock). The chip features the HD graphics 510 chip with clock speeds of 300 MHz base and 950 MHz boost clock and support for DDR4, DDR3L and LPDDR3 memory. The chip comes with 2 MB of L3 cache and has a TDP of 15W that is configurable down to 10W. The Celeron 3955U and Celeron 3855U have dual core designs without hyperthreading, HD graphics 510 iGPUs clocked at 300 MHz base, 900 MHz boost, 2 MB of L3 cache and 15W TDPs. The 3955U is clocked at 2.0 GHz while the 3855U is clocked at 1.6 GHz.

Intel Skylake-U 28W Chips With Iris Graphics in Q1 2016

Lastly, we should expect a total of four Skylake-U chips with TDPs of 28W arriving in Q1 2016. These chips will replace the Broadwell-U family and feature Iris Graphics chip which have better performance compared to the traditional Intel HD graphics chips found on the rest of the Skylake-U lineup. The specifications of the Skylake-U family can be found below:
