Coffee Lake is Intel's codename for its eighth-generation Core microprocessor family, announced on September 25, 2017. [5] It is manufactured using Intel's second 14 nm process node refinement. [6] Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores (along with hyper-threading in the case of the latter) and Core i3 CPUs with four cores and no hyperthreading.

Contents

On October 8, 2018, Intel announced what it branded its ninth generation of Core processors, the Coffee Lake Refresh family. [7] To avoid running into thermal problems at high clock speeds, Intel soldered the integrated heat spreader (IHS) to the CPU die instead of using thermal paste as on the Coffee Lake processors. [8] The generation was defined by another increase of core counts.

Coffee Lake is used with the 300-series chipset, and officially does not work with the 100- and 200-series chipset motherboards. Although desktop Coffee Lake processors use the same physical LGA 1151 socket as Skylake and Kaby Lake, the pinout is electrically incompatible with these older processors and motherboards. [9]

On April 2, 2018, Intel released additional desktop Core i3, i5, i7, Pentium Gold, Celeron CPUs, the first six-core Core i7 and i9 mobile CPUs, hyper-threaded four-core Core i5 mobile CPUs, and the first Coffee Lake ultra-power CPUs with Intel Iris Plus graphics.

On June 8, 2018, to commemorate the 40th anniversary of the Intel 8086 CPU architecture, Intel released the i7-8086K as a limited edition CPU, a renumbered and slightly higher clocked batch of the i7-8700K dies.

History

Coffee Lake's development was led by Intel Israel's processor design team in Haifa, Israel, as an optimization of Kaby Lake. [10] Intel first launched its 8th Generation Intel Core family processors in August 2017. While with the release of the new 8th Gen Intel Core i9 processor in 2018, Intel said it would be the highest-performance laptop processor Intel has ever built. [10]

Coffee Lake CPUs are built using the second refinement of Intel's 14 nm process (14 nm++). [6] It features increased transistor gate pitch for a lower current density and higher leakage transistors that allows higher peak power and higher frequency at the expense of die area and idle power.

Coffee Lake marks a shift in the number of cores for Intel's mainstream desktop processors, the first such update for the previous ten-year history of Intel Core CPUs. In the 8th generation, mainstream desktop i7 CPUs feature six hyperthreaded cores, i5 CPUs feature six single-threaded cores and i3 CPUs feature four single-threaded cores.

9th generation

For the 9th generation, the Intel Core i9 branding made its debut on the mainstream desktop, describing CPUs with 8 cores and 16 threads. 9th generation i7s feature 8 single-threaded cores, marking the first time desktop Core i7s have not featured Intel's Hyper-threading technology, although the 9th generation Core i7 mobile CPUs do support hyperthreading and have 6 cores just like 8th gen mobile chips. 9th generation i5 CPUs feature six single-threaded cores, just like their 8th generation predecessors.

The ninth generation Core i series includes hardware fixes for Meltdown and L1 Terminal Fault. [11]

Chipsets

The 300 series chipsets, while using physically identical LGA 1151 socket to the 100 and 200 series chipsets, are officially only compatible with Coffee Lake CPUs, meaning that older motherboards do not officially support Coffee Lake processors, [12] [9] and 300 series motherboards do not officially support Skylake or Kaby Lake processors.

The enthusiast Z370 (a rebranded Z270), launched alongside the first Coffee Lake CPUs in October 2017, was the only officially supported chipset for these mainstream CPUs. When the full lineup of CPUs was revealed in April 2018, it was then accompanied by the lower-end H310, B360, H370 and Q370 chipsets for home and business users. The Z390 chipset was launched alongside the release of the 9th generation CPUs, supporting all 8th and 9th generation mainstream desktop parts. A B365 chipset was added later on.

9th generation Xeons require motherboards with the C246 chipset. [13]

Architecture changes compared with Kaby Lake

Coffee Lake features largely the same CPU core and performance per MHz as Skylake/Kaby Lake. [14] [15] Features specific to Coffee Lake include:

Kaby Lake Refresh vs. Coffee Lake

On August 8, 2017, Intel announced the first of its new eighth generation of processors would be mobile processors. [16] As Intel's previous changes in product generations coincided with new microarchitectures, it was unclear [17] but generally expected that the eighth Core generation products would be based on the new Coffee Lake microarchitecture. [18] When it was officially announced on August 21, 2017, however, Intel stated that the eighth generation family would be based on multiple microarchitectures: Kaby Lake Refresh, Coffee Lake, [19] Whiskey Lake, and Cannon Lake. [20]

The first 9th generation Coffee Lake CPUs were released in the fourth quarter of 2018. They include hardware mitigations against certain Meltdown/Spectre vulnerabilities. [25] [26]

The main differences from the 8th generation (besides increased frequency) are:

Even though the CPUs with F suffix lack an integrated GPU, Intel set the same price for these CPUs as their featureful counterparts. [27] Intel eventually reduced the official pricing of those CPUs in October 2019. [28]

The Intel Core i9-9900KS CPU, released at the end of October 2019, features a limited one year warranty both for box and tray versions due to "its limited volume". [29]

In computing, Direct Media Interface (DMI) is Intel's proprietary link between the northbridge and southbridge chipset on a computer motherboard. It was first used between the 9xx chipsets and the ICH6, released in 2004. Previous Intel chipsets had used the Intel Hub Architecture to perform the same function, and server chipsets use a similar interface called Enterprise Southbridge Interface (ESI). While the "DMI" name dates back to ICH6, Intel mandates specific combinations of compatible devices, so the presence of a DMI does not guarantee by itself that a particular northbridge–southbridge combination is allowed.

Tick–tock was a production model adopted in 2007 by chip manufacturer Intel. Under this model, every microarchitecture change (tock) was followed by a die shrink of the process technology (tick). It was replaced by the process–architecture–optimization model, which was announced in 2016 and is like a tick–tock cycle followed by an optimization phase. As a general engineering model, tick–tock is a model that refreshes one side of a binary system each release cycle.

Comet Lake processors and Ice Lake 10 nm processors are together branded as the Intel "10th Generation Core" family. In March 2021, Intel officially launched Comet Lake-Refresh Core i3 and Pentium CPUs on the same day as the 11th Gen Core Rocket Lake launch. The low-power mobile Comet Lake-U Core and Celeron 5205U CPUs were discontinued on July 7, 2021.

<span class="mw-page-title-main">LGA 1200</span> CPU socket for Intel desktop processors

LGA 1200, also known as Socket H5, is a zero insertion force flip-chip land grid array (LGA) socket, compatible with Intel desktop processors Comet Lake and Rocket Lake (11th-gen) desktop CPUs, which was released in April 2020.

Rocket Lake is Intel's codename for its 11th generation Core microprocessors. Released on March 30, 2021, it is based on the new Cypress Cove microarchitecture, a variant of Sunny Cove backported to Intel's 14 nm process node. Rocket Lake cores contain significantly more transistors than Skylake-derived Comet Lake cores.

<span class="mw-page-title-main">Alder Lake</span> Intel microprocessor family

Alder Lake is Intel's codename for the 12th generation of Intel Core processors based on a hybrid architecture utilizing Golden Cove performance cores and Gracemont efficient cores. It is fabricated using Intel's Intel 7 process, previously referred to as Intel 10 nm Enhanced SuperFin (10ESF). The 10ESF has a 10%-15% boost in performance over the 10SF used in the mobile Tiger Lake processors. Intel officially announced 12th Gen Intel Core CPUs on October 27, 2021, mobile CPUs and non-K series desktop CPUs on January 4, 2022, Alder Lake-P and -U series on February 23, 2022, and Alder Lake-HX series on May 10, 2022.

<span class="mw-page-title-main">Raptor Lake</span> Line of Intel microprocessors, released in 2022

Raptor Lake is Intel's codename for the 13th and 14th generations of Intel Core processors based on a hybrid architecture, utilizing Raptor Cove performance cores and Gracemont efficient cores. Like Alder Lake, Raptor Lake is fabricated using Intel's Intel 7 process. Raptor Lake features up to 24 cores and 32 threads and is socket compatible with Alder Lake systems. Like earlier generations, Raptor Lake processors also need accompanying chipsets. Raptor Lake CPUs have suffered issues with permanent damage from elevated voltage due to a vulnerable clock tree circuit, resulting in instability. Intel claims these issues have been since fixed in the latest microcode patches, which requires updating the motherboard's BIOS.
