Everything We Know About Intel's Skylake Platform

Skylake Consumer And Business Chipsets

Since the release of Intel's Skylake-based processors, we have been working tirelessly to learn everything there is to know about the architecture and its associated platform. The information we have accumulated over a number of months, but it seems to be constantly changing, creating confusion among tech enthusiasts. And so we're aiming to clear up conflicting information and condense everything we know about the Skylake platform down into a single resource.

Intel released a total of six chipsets targeting its consumer
and business customers. These platform controller hubs follow the same structure used for years to cover Intel's relevant markets. Three are consumer-oriented SKUs and three are designed for business.

At the high end, we have the enthusiast Z170 chipset. In addition to featuring RAID 0/1/5/10, multi-GPU support and offering a wide selection of connection options, it is also the only PCH officially able to overclock Skylake-based processors. Z170 is followed up by the mid-range H170, which also offers a lot of I/O connectivity and RAID 0/1/5/10 functionality, but lacks overclocking and multi-GPU support via the CPU.

H170 is often advertised as supporting multiple graphics cards, but motherboards based on it can only run a multi-GPU setup in a x16/x4 configuration. This is because the PCH doesn't allow the CPU to divide its PCIe lanes between multiple devices. A second GPU can be connected over a four-lane PCIe 3.0 link through the PCH, which may be sufficient for some GPUs, but Nvidia doesn't let you enable SLI over a x4 connection.

At the bottom of the consumer chipset stack is H110, by far the most limited PCH. Instead of using a DMI 3.0 connection between the CPU and core logic, it employs the older DMI 2.0 technology. It's basically a budget-oriented approach to supporting Skylake-based processors.

The business-oriented chipsets are similar to the consumer offerings, though they include a few extra features that consumers don't necessarily need.

Q170 is nearly identical to Z170, but of course lacks overclocking support. Moreover, it features Intel SIPP, vPro Technology and Active Management Technology. Q150 is nearly the same as H170 as well, except it has fewer HSIO and PCIe lanes. Plus it lacks RAID and Intel’s Small Business Basics software package. It is eligible for Intel’s SIPP technology, though.

The low-end B150 business chipset, however, does not match up well with H110. It offers more connectivity, DMI 3.0 and PCIe 3.0. Because of its budget price and specs, B150 is often used by consumers as a more feature-rich alternative to H110.
