These are some Skylakes ready to work in future laptops

Since Intel prepares to launch the mobile version of the Skylake, like the Skylake U, Intel has decided to bring out the low and ultra-low power consumption CPUs best suited for laptops and mobile computing platforms.

While the Skylake-U platform stands somewhere below the more powerful Skylake “H” models, the “Y” models will be the most eco-friendly out of the entire Skylake line, offering a thermal design power of 4.5 Watts compared to its more power-hungry 15 Watt TDP Skylake-U bigger brother. The models introduced with these specs are the 6Y30, 6Y54, 6Y57, 6Y75 "Y" series microprocessors.

According to CPU World, the new Skylake-Y processors will get new branding denominations like Core m3, Core m5 or Core m7, depending on their performance. Although the new names are speculated online, it is unknown if this will be their final, official designation. However, the numbers in their name suggest a possible match with their family brand, as the 6Y30 belongs to Core m3 family, the 6Y54 and 6Y57 belong to Core m5 family, and the 6Y75 is from Core m7 family.

Skylake-Ys are ready to join their “S,” “U” and “H” brothers in mobile applications

However, family and brand names do not apply to number of cores/threads, L3 cache memory, and integrated graphics. They all share the same, 4MB L3 cache, HD 515 integrated graphics clocked at 300MHz, and all have 2 CPU cores and 4 virtual cores. On the other hand, the difference between Core M models is in CPU and GPU clock speeds, and whether they support vPRo technology or not. The lowest entry model is clocked at 900 MHz and is boostable to 2,2GHz for one core, while its maximum GPU frequency is 850 MHz. The other Core m5 6Y54 and 6Y57 operate at 1.1 GHz, and their maximum Turbo Boost frequency is 2.4 GHz for both cores, or 2.7 GHz and 2.8 GHz for one core, and their GPUs has a maximum dynamic frquecy of 900Mhz.

Core m5 GPU has a maximum dynamic frequency of 900 MHz. The Core i7 6Y75 clocks at 1.2 GHz, and up to 3.1 GHz. Core m7 GPU is clocked at up to 1 GHz. The CPUs support VT-x and VT-d virtualization, and AES instructions. The Core m5 6Y57 and Core m7 6Y75 also support vPro and Trusted Execution technologies.

Connectivity-wise, all chips have up to 2 SATA 6Gb/s ports, 10 lanes of PCI-Express interface, 6 USB2/USB3 ports and eMMC 5.0 interface. They support USB OTG and Rapid Storage Technology 14. Memory-wise, the new Core M CPUs support DDR3L-1600 and LPDDR3-1866 memory, but they do not support DDR4, so that’s a good thing to keep in mind. While they are rated with 4.5 Watt TDP and 3 Watt SDP, they can be overclocked to 7 Watt TDP.  

Model Cores/Threads Frequency/Turbo L3 Cache Graphics GPU Frequency TDP
Core m3 6Y30 2 / 4 900 MHz / 2.2 GHz 4 MB HD 515 300 / 850 MHz 4.5 Watt
Core m5 6Y54 2 / 4 1.1 / 2.7 GHz 4 MB HD 515 300 / 900 MHz 4.5 Watt
Core m5 6Y57 2 / 4 1.1 / 2.8 GHz 4 MB HD 515 300 / 900 MHz 4.5 Watt
Core m7 6Y75 2 / 4 1.2 / 3.1 GHz 4 MB HD 515 300 / 1000 MHz 4.5 Watt
