Then a jump to 14nm, Broadwell is a Tick in the release schedule to be followed by a Tock, Skylake. For Skylake several things changed, an increasingly more powerful graphics engine and that fabrication shrink to the 14nm node, this allows for an even more power friendly processor. There's another TOCK though, that is Kaby Lake, a respin at 14nm.

For this motherboard review we will use the unlocked Core i5 7600K.

Intel Core i5-7600K Processor Key Features

• Intel Turbo Boost Technology 2.0: Dynamically increases the processor frequency up to 4.2 GHz when applications demand more performance. Speed when you need it, energy efficiency when you don’t.
• Intel Smart Cache: 6MB of shared cached allows faster access to your data by enabling dynamic and efficient allocation of the cache to match the needs of each core, significantly reducing latency to frequently used data and improving performance.
• CPU Overclocking Enabled (with Intel Z270 chipset): Fully unlocked core multiplier, power, base clock and memory ratios enable ultimate flexibility for overclocking.
• Graphics Overclocking Enabled (with Intel Z270 chipset): Unlocked graphics multiplier allows for overclocking to boost the graphics clock speed.
• Integrated Memory Controller: Supports 2 channels of DDR4-2400 and DDR3L-1600 memory with 2 DIMMs per channel. Support for memory based on the Intel Extreme Memory Profile (Intel XMP) specification.
• PCI Express 3.0 Interface: Supports up to 8 GT/s for fast access to peripheral devices and networking with up to 16 lanes configurable as 1x16, 2x8, or 1x8 and 2x4 depending on the motherboard design.
• Chipset/Motherboard Compatibility: Compatible with all Intel 100 Series chipsets with the latest BIOS and drivers.
• Intel HD Graphics 630: Integrated 3D performance with support for Microsoft DirectX 12 and Ultra HD 4K resolution display for immersive mainstream gaming. For Microsoft DirectX 12 testing, the performance-tuned Intel graphics driver is expected to be available for download on Intel Download Center by the 6th generation Intel Core processor family product introduction. The Intel HD Graphics 630 dynamic graphics frequency ranges up to 1150MHz.
  • Vibrant Media: Enhanced, built-in visual features deliver a seamless visual PC experience for rich Ultra HD 4K entertainment and HD gaming.
  • Intel Quick Sync Video Technology: Media processing for incredibly fast conversion of video files for portable media players or online sharing including support for HEVC (H.265) encode/decode to support Ultra HD 4K.

Of course there will be a distinction per processor segment with the 5th generation (i3/i5/i7). What you get in terms of features and what you need to remember limitation wise:

• Desktop Core i7 processors have four cores / eight hyper-threads / Up to 8 MB L3 cache
• Desktop Core i5 processors have four cores / NO hyper-threading / Up to 6 MB L3 cache
• Desktop Core i3 processors have two cores (unannounced)

All models will come with the latest revision turbo mode but only the Core i7 series will be capable of handling multiple independent software threads per core, also known as hyper-threading. It's a feature we like very much as it really helps out on peak performance by allowing a processor to execute two different code streams at pretty much the same time.

Quite a few processors will be based on Kaby Lake, we focus on desktop, let's have a closer look.

Core i5-7600K and i7-7700K

Both models released are unlocked (multiplier & voltage) quad-core processors based on the aforementioned architecture and supersedes the Core 4000 and 6000 processor range (in design). The Core i7 model has hyper-threading and your OS will see it as an 8-core product. The CPU has 1 MB L2 cache (256 KB per physical core). Then there is an 8MB shared L3 cache. The integrated memory controller remains dual-channel, officially supporting up-to 2400MHz, but we all know how high these puppies can clock. The TDP for this processor is now rated at 91 Watts. The Core i5 model is a fairly similar product, yet clocked a notch slower at a 3.8 GHz base clock and 4.2 GHz Turbo allowance. This processor, as stated, does not have hyper-threading. Also it has slightly less L3 cache at its disposal, 6 MB.

Core i7 7700K - 4 cores and Hyper-Threading, 4.2 GHz frequency, 4.5 GHz maximum Turbo Boost frequency, 8MB last-level cache, dual-channel DDR3/DDR4 memory controller with 1600MHz, 2133MHz or 2400MHz support, Intel HD Graphics 630-series integrated graphics core, LGA1151 packaging.

Core i5 7600K - 4 cores, 3.80GHz frequency, 4.20GHz maximum Turbo Boost frequency, 6MB last-level cache, dual-channel DDR3/DDR4 memory controller with 1600MHz, 2133MHz or 2400MHz support, Intel HD Graphics 630-series integrated graphics core, LGA1151 packaging.

There will be more variants available later this year though (bear in mind that we do not have a final list of supported clock frequencies so the table below will be updated once the numbers get in:

The Kaby Lake cache memory consists of a 32 KB L1 Data cache, 32 KB Instruction cache (= 64 KB L1) and then we spot a 256 KB L2 cache per core (1MB total) and then there's a L3 cache that is shared in-between the CPU cores which is 8 MB in total for the Core i7 processors and 6 MB for the Core i5 series. This has been the same for many generation Intel processors in this class.

The L3 cache sits in the physical form of a ring-bus. Thus the L3 cache can be used by the processor cores and also the graphics core. You can house the new processors on motherboards with the H270 and Z270 chipset and will be introduced later on other business oriented chipsets as well. The H170/Z170 chipsets are compatible after a motherboard BIOS update. For end consumers like you and me the H series chipset is less performance targeted and comes with better support for HTPC monitor connectivity. The Z series chipset is targeted at performance and enthusiast end users allowing much more tweaking and providing performance features. It also brings USB 3.1, SATA Express and PCIe M.2 SSD connectivity to the platform.
