Coffee Lake (CFL) is a microarchitecture designed by Intel as a successor to Kaby Lake for desktops and high-performance mobile devices. Coffee Lake was introduced in the third quarter of 2017 and is manufactured on Intel's mature 14 nm process. Coffee Lake features the first series of mainstream hexa-core processors from Intel.

Release Dates

Early roadmaps indicated Coffee Lake was to be introduced around the second quarter of 2018. In early 2017 Intel announced that 8th generation processors will be available starting from the 3rd quarter of 2017. While the exact reason for the early release is unknown, it seems likely to attribute the move to various market forces, particularly AMD's introduction of Zen and the Ryzen family.

Intel announced Coffee Lake-based SKUs on September 24 with products available beginning October 5, 2017 and OEM systems starting Q4 2017.

Technology

See also: Broadwell § Process Technology and 14 nm lithography process

Coffee Lake is manufactured on Intel's 3rd generation 14 nm process called "14nm++". The process is the second enhanced version of the first which was used for the Broadwell microarchitecture (first enhanced version was first used for Kaby Lake). The various enhancements improve performance without increasing the capacitance (i.e., active power characteristics). 14nm++ allows for +23-24% higher drive current. Intel claims their 14nm++ process provides 26% more performance for 52% less power.

Note that while both "14nm" and "14nm+" used the same transistor geometry, the "14nm++" actually uses a more relaxed contacted poly pitch of 84 nm (from previously 70nm). It's unknown what kind of effect this has on the overall density, if any.

Architecture

Coffee Lake is 8th Generation Core

While there is no change in pure IPC over Skylake and the actual microarchitecture is largely the same, Intel introduced a number of major architectural changes in Coffee Lake. In addition to improved performance brought by the uplift in binning as a result of the enhanced process, Coffee Lake also increased the number of cores by 50%, enabling much higher multi-threaded performance. The enhanced manufacturing process should allowed Coffee Lake chips to be highly overclockable.

Overview

The Coffee Lake system on a chip consists of a five major components: CPU cores, LLC, Ring interconnect, System Agent, and the integrated graphics. The core architecture in Coffee Lake, like in Kaby Lake, as not changed from Skylake. Likewise, the integrated graphics is identical to the one incorporated in Kaby Lake and from a platform point of view, the I/O has not changed (supporting up to 3 displays and providing 16 PCIe Gen 3 lanes).

Historical Trend

Despite the lack of enhancements to the individual components, Coffee Lake presents the largest change in the system architecture of Intel's mainstream microarchitecutre since the introduction of Sandy Bridge in 2011. In 2006 Intel introduced the first mainstream quad-core processor, the Core 2 Extreme QX6700 which was based on the Kentsfield core. Those initial quad-cores comprised of two separate dies interconnected in a multi-chip package. This configuration did not change through Penryn up until the introduction of the Core i7 Extreme based on the Nehalem microarchitecture in 2008. Nehalem leveraged Moore's Law and Intel's 45 nm process to incorporate all four cores onto a single die along with a large number of changes, particularly enhancing the uncore (now known as the System Agent).

With the introduction of Sandy Bridge in 2011, the entire system architecture was reworked. A particular goal of Sandy Bridge was its configurability. Intel wanted to be able to use a single design across multiple market segments without having to spend extra resources on multiple physical designs. A large part of its molecularity came from the ring interconnect Sandy Bridge implemented. It's worth pointing out that the implementation in Sandy Bridge is largely based on an enhanced version first implemented in Nehalem-EX server parts. The ring allowed Intel to integrate the System Agent and the integrated graphics on-die in Sandy Bridge. Each of those components had its own ring agent (in addition to the individual core), allowing for efficient transfer of data between the GPU, the SA, and the individual cores and caches. The final result was a complete system on a chip with four cores and a 12 EU GPU on a single die measuring consisting of 1.16 billion transistors on a 216 mm² die.

From Sandy Bridge through 22 nm Haswell and through 14 nm Skylake, the die shrunk considerably, even after large amount of enhancements (and thus transistors) were done to the microarchitecture. With the aid of Moore's Law, the quad-core die in Coffee Lake's predecessor, Kaby Lake, has reached 126 mm² - 42% smaller than the quad-core Sandy Bridge while packing over 3 times as much transistors.

Since Coffee Lake utilizes Intel's 3rd generation enhanced 14nm++ process which has reached maturity and healthy yield, Intel can afford to increase the amount of cores by 50% from 4 to 6 cores. This is also possible thanks to the existing ring interconnect that was designed specifically to be able to support this configuration. In addition to the two addition cores, there are two addition LLC slices - each consisting 2 MiB in size.
