Intel is going to launch their unlocked Skylake processors, the Core i7-6700K and Core i5-6500K on 5th August 2015. The latest report on these processors comes from Benchlife who have received details on roadmap concerning the launch of Intel Skylake processors for the desktop platform along with chipset launches in the 100-series lineup.

Intel Skylake Core i7-6700K and Core i5-6500K Processors Launching on 5th August Along With Z170 Motherboards

Intel is planning to roll out their unlocked processors first on 5th August alongside the Z170 boards which will be the top end parts for the mainstream and enthusiast market. These will be followed by low power and unlocked variants that will begin shipping, starting from 30th August. Other markets such as the emea and asmo regions have different dates for SKU sales but the embargo will be lifted at a similar time frame. Around the same time, we can expect H170, B150, H110, Q170, Q150 chips in the market but the solution for corporate sectors will be introduced around October-November ’15 timeframe. For specifications, we have the following chips:

Intel 95W “Enthusiast” Skylake-S Processors (Core i7-6700K / Core i5-6600K)

The first two processors that include the Core i7-6700K and Core i5-6600K were leaked a few days ago and are labeled as “Enthusiast” 95W processors. Starting off with the flagship Core i7-6700K CPU, we are looking at a quad core design with eight threads which shows a multi-threaded design. The chip features 8 MB of L3 cache and has clock speeds maintained at 4.0 GHz base and 4.2 GHz boost clock. The chip can support DDR4 2133 MHz memory and DDR3L 1600 MHz memory.

Similarly, the Core i5-6600K is the more cost conservative enthusiast offering and being a quad core, it stays away from a multi-threaded path. The clock speeds are maintained at 3.5 GHz base and 3.9 GHz boost and has a total of 6 MB of L3 cache with similar DDR4/DDR3L memory support as the top offering.


Intel 65W “Mainstream” Skylake-S Processors (Core i7 / Core i5)

Coming to the mainstream lineup, we are looking at 4 chips which include the Core i7-6700 that features same specifications as the Core i7-6700K but doesn’t come in an unlocked package. Similarly, the Core i5-6600 also has the same specifications as seen on the unlocked model but without the K-Series design that allows over-clocking support. Clocks for the Core i7-6700 are maintained at 3.4 GHz base and 4.0 GHz boost while the Core i5-6600 is clocked at 3.3 GHz base and 3.9 GHz boost. The Core i5-6500 is a quad core clocked at 3.2 GHz base and 3.6 GHz boost while the Core i5-6400 is a quad core clocked at 2.7 GHz base and 3.3 GHz boost. All of these chips feature a 65W TDP and the Core i5 models pack 6 MB of L3 cache while the Core i7 model gets 8 MB L3 cache.

Intel 35W “Low TDP” Skylake-S Processors (Core i7 / Core i5)

Over at the more power efficient side, Intel will launch 4 T-Series chips which stand for low-power. All chips feature just 35W TDP and include Core i7-6700T as a multi-threaded quad core with 2.8 GHz base and 3.6 GHz boost clock. It packs 8 MB of L3 cache. The Core i5 models range from the Core i5-6600T, Core i5-6500T and Core i5-6400T featuring 6 MB of L3 cache, quad core (non-multithreaded designs) and boost speeds ranging from 2.8 to 3.6 GHz.

These Skylake processors will have several features that include increase IA and graphics performance at much lower power than their predecessors. While the TDP remains 95W, Intel has further improved the efficiency of these new chips hence delivering much better performance. The Skylake processors will support both DDR3L and DDR4 memory types. The DDR3L memory will be available on the mini-PC designs such as All-in-ones and NUCs while traditional PCs which will get Z170 and H170 series motherboards will have native support for DDR4 DIMMs. The unlocked processors options which are also the Enthusiast CPUs as detailed above will allow enhanced full range BCLK overclocking. Hopefully, Intel will use better TIM or Soldering to prevent any heating issues on the dense 14nm chips. Other features includes Turbo Boost 2.0, Hyper Threading, DMI 3.0, 3 digital displays capability (including embedded Display Ports), HEVC, VP8, VVP9, AMCs and support for the latest APIs such as DirectX 12, OpenGL 4.3/4.4 and OpenCL 2.0.
