Intel Kaby Lake Desktop CPU Lineup Leaked – Core i7-7700K Leads the Pack, Boosts Up to 4.5 GHz


Intel's 7th generation Kaby Lake desktop processor family has been leaked by Chinese sources, confirming the various SKUs of the lineup. Detailed on IDF'16, the Kaby Lake processors will feature an optimized architecture that will be designed with the building blocks of Skylake that came before it. The Kaby Lake processors will be featured on multiple platforms but our focus today is on the mainstream desktop chips.

Along with the details for the lineup, Coolaler mentions that the desktop chips for the mainstream platform will be slightly delayed to early 2017. Right now, Intel plans to bring out their mobility processors based on the Kaby Lake architecture as soon as possible. Intel revealed at IDF that their mobile chips are already being shipped to OEMs. There main focus of 2016 is to bring as much Kaby Lake chips to mobile form factors (4W - 15W) during Fall 2016 before moving to the desktop side.

Coming to desktop itself, there will be two different variants of the chips themselves. One would be designed for the HEDT market while the others will be designed for the mainstream market. The HEDT lineup is known as Kaby Lake-X and will be featured on the LGA 2066 along with the Skylake-X processors. The mainstream lineup which is internally known as Kaby Lake-S will be featured on the LGA 1151 socket. While this socket is the same as Skylake before it, the change it chipset (200-series) would not allow compatibility with older generation (100-series) motherboards.

The 7th Generation Intel Core Desktop Lineup:

Intel's K Series Kaby Lake CPUs:

So talking about the details, first up, we have two "K" series models. These chips have an unlocked design that indicates that they are built for overclocking. The flagship is the Core i7-7700K features 4 cores, 8 threads and 95W TDP. This chip has a base clock of 4.2 GHz and boost clock of 4.5 GHz while featuring 8 MB of L3 cache. The Core i5-7600K is a quad core chip without multi-threading support that packs 6  MB of L3 cache and a 95W TDP. The chip features a base clock of 3.8 GHz and would turbo beyond 4 GHz.

Intel's S Series Kaby Lake CPUs:

There are four standard models which include the Core i7-7700, Core i5-7600, Core i5-7500 and the Core i5-7400. The Core i7-7700 comes with a quad core (multi-threaded) design and a base clock of 3.6 GHz. TDP on this model is set at 65W along with 8 MB of L3 cache. Rest of the three Core i5 models are quad core variants without multi-threading support. Clock speed range from 3.5 GHz on the 7600, 3.4 GHz on the 7500 and 3.0 GHz on the 7400.

Intel's T Series Kaby Lake CPUs:

There are also several "T" variants which means low power. These variants have been designed for low-power desktop PCs. TDP on all of these models is set to 35W and include the Core i7-7700T, a multi-threaded quad core processors running at 2.9 GHz along with 8 MB of L3 cache. The Core i5-7600T comes with a base clock of 2.8 GHz, the Core i5-7500T comes with a base clock of 2.7 GHz and the Core i5-7400T comes with a base clock of 2.4 GHz. All Core i5 models have 6 MB of L3 cache embedded inside them.

Here’s What To Expect From Kaby Lake Desktop Processors

Intel Kaby Lake processors in general would be getting increased core performance (expect the usual 5-10% improvement) unless Intel plans to do something very different with Kaby Lake which seems highly unlikely. The processors will retain the basic features such for enthusiasts such as enhanced full range BCLK overclocking and 95W “Unlocked” options to choose from.

While Intel has increased the core count on their enthusiast chip platform (Broadwell-E), things will remain the same on their mainstream platform with both dual and quad core (35W and 65W options) available to consumers along with the enthusiast quad core options. Other key features on the media and display side include 5K (30Hz) on one display and 5K (60Hz) dual display capabilities, HEVC 10-bit hardware decode, VP9 10-bit (hardware), UDH/4K display resolutions and support for Intel’s Thunderbolt gen3 support.

The Intel 200-Series PCH is a crucial update for the upcoming family of processors as it will allow support for them. The Intel 200-series PCH will include several SKUs such as Z270, H270, Q270, Q250 and B250. While the new chipset doesn’t include any major changes over the Skylake PCH, it does include support for Intel Optane technology which utilizes Intel’s 3D XPoint memory to deliver high-performance SSDs and memory solutions.

The KBL-PCH will be able to support Mansion Beach (Optane SSD PCIe/NVMe Gen3 x4), Brighton Beach (Optane SSD PCIe/NVMe Gen3 x4) and Stony Beach (Optane Memory PCIe/NVMe Gen 3 x2 (m.2)) solutions. We covered this topic in more detail over here.
