Overview of Intel Skylake CPUs For Laptop, 2-in-1, and Tablet PCs

Intel Presents a 2-in-1 Laptop with Skylake Processor

Intel has officially unveiled their upcoming “Skylake” processors for laptops, 2-in-1 PC, tablets, and other mobile PCs, besides desktops. The next-gen mobile CPUs are based on the same 14-nanometer production process as their “Broadwell” precursors, but they bring several architecture improvements for better performance, power efficiency, and multimedia capabilities.

With clock speeds 0.1 or 0.2 GHz higher than the corresponding older models, the Skylake mobile processors won’t be much faster when in comes to raw computing power. Depending on model, the boost will go up to 17 percent, according to Intel. Changes in the integrated graphics department aren’t revolutionary either, but Intel claims improvements over the previous integrated GPU lineup bring “up to 41 percent” better performance (on the Intel Core M series), also depending on model. We’ll still need to see the mobile Skylake benchmark results to give a final judgment about Intel’s claims.

With Skylake, Intel introduces brand new power-saving technology called Speed Shift. It’s designed to improve battery life of laptops and other devices, especially in certain scenarios, such as movie playback and idle state.

Regarding multimedia, Intel promises improved video and image processing via dedicated hardware on the CPU. The Skylake CPUs will provide users with smoother and more power-efficient high-resolution video playback and faster video transcoding acceleration, such as converting large 4K video files to lower-quality but smaller ones. For photographers, it’s worth noting that Intel has added hardware acceleration for converting DSLRs’ RAW images to standard formats such as .jpeg. Skylake also enables smooth high-resolution video recording using up to two video streams / cameras simultaneously. Supported video capture resolution is 1080p Full HD at 60Hz and 2160p Ultra HD (4K) at 30Hz.

To make Skylake more future-proof, Intel has added support for DDR4 RAM memory on select SKUs, while retaining support for DDR3 standard. Use of both memory types on the same platform is enabled thanks to new UniDIMM universal memory slots.

Alongside these improvements, Intel has enhanced other parts of the platform, such as Wi-Di wireless display technology, which now supports Ultra HD 4K (30Hz) wireless video streaming to external display instead of just Full HD. Regarding wired video output, Skylake adds support for up to 3 Ultra HD 4K monitors simultaneously. The chip maker has also implemented in the computing platform support for Thunderbolt 3.0 interface with fast 40 Gbps data transfers from an to compatible external devices, new USB-C standard, wireless charging, and more. These features, however, won’t be implemented on all, but only on select Skylake-based computer models.

Specifications and release dates for most Skylake processors are available now. They will start shipping in September.
