Intel’s 6th Generation Skylake-S Processor Lineup Leaked – Core i7-6700K Leads The Pack, 10 SKUs Detailed, First Sample Spotted


Intel's 6th generation Skylake-S processor lineup has been leaked, detailing 10 desktop processors which will be powering the next generation desktop platform. The consumer platform which will be based off the 100-series chipset is expected to launch at IDF15 in San Francisco along with several desktop chips which will range from 95W performance (enthusiast) variants to 65-35W power efficient variants. The leaked information was posted by benchlife.info (via PCGameshardware).

Intel's Skylake-S Desktop Processor Lineup Leaked - Core i7-6700K Flagship and 9 Core i7/Core i5 SKUs

We have plenty of details regarding the Skylake-S platform which is going to launch for desktop consumers. We know the chips that are going to power the motherboards and the details regarding the processors feature set is known in detail. The only thing that remains to be covered regarding Skylake-S family of CPUs is the number of SKUs which will be included in the lineup and what architectural improvements are we looking at when it comes to both CPU and GPU side. For the lineup, we are looking at a total of 10 Skylake-S chips which are detailed and listed below:

  • Intel Core i7-6700K
  • Intel Core i5-6600K
  • Intel Core i7-6700
  • Intel Core i5-6600
  • Intel Core i5-6500
  • Intel Core i5-6400
  • Intel Core i7-6700T
  • Intel Core i5-6600T
  • Intel Core i5-6500T
  • Intel Core i5-6400T

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.

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.

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. The specifications can be seen in detail in the chart below:

First Intel Skylake-S Engineering Sample Spotted:

What is more impressive about the leak is the fact that we are looking at the first Intel Skylake-S based engineering sample. The chip shown by the source is a very early sample and a quad core that operates at just 2.2 GHz however we know what the final specs of the SKUs would be like. The chip shown off has a totally new contact surface compared to past processors and the substrate that holds the die is less thicker compared to Haswell and Ivy Bridge series chips. No benchmarks or exact details were mentioned but we will also get a glimpse at them in the future reports.
