![]() The Pentium Gold CPUs now sport a 2-core/4-thread setup, with the Celeron filling in the 2-core/2-thread space. The Core i3 CPUs were now four-core CPUs without hyperthreading.Ī later Coffee Lake refresh confused things a bit more, with Core i7 competing with AMD Ryzen, going up to 8 cores without Hyperthreading. ![]() These new processors broke form (likely under pressure from AMD's successful Ryzen lineup), with i5 and i7 CPUs now having six cores. They mate with 300-series chipsets (and are not officially compatible with 100/200 series). Coffee LakeĬoffee Lake CPUs, now i3/i5/i7 8-series based on the 14nm++ (refinement), have been available to the public since Q3 2017. It seems the market also found these chips less than appealing, and Intel discontinued its Kaby Lake X parts after a little over a year on the market. Curiously, these CPUs' respective 4-core/8-thread and 4-core/4-thread designs, more akin to mainstream chips, made them an odd choice for "HEDT" which had more recently started at 6-core/12-thread configurations. Core counts also remained the same on the mobile side.įor the HEDT platform, Intel surprisingly released the i7-7740X and i7-7640X CPUs, which of course fit in the LGA 2066 socket like its Skylake-X predecessors. Kaby Lake mobile CPUs made their appearance early in 2017 as well, with their naming scheme now using the i3/i5/i7 7xxx series CPUs along with a couple of Pentium 44xx (the "G" naming was removed) and Celeron and Celeron 3xxx series CPUs. The integrated GPU was also improved and uses the HD 6-series naming offering better performance than the previous 5-series. These are increases of 200 Mhz base clock and 300 Mhz for single-core turbo, while fitting into the same 91W TDP. Core counts remained unchanged in this generational bump, though clock speeds ranged from 2.4 GHz to 4.5 GHz. Kaby Lake processors hit the scene using the i3/i5/i7-7xxx naming schemes with the Pentiums now using G4 6xx and Celeron G3 9xx. This was also the first set of processors to bring with it support for Intel's Optane Memory. Architectural changes included increased clock speeds, faster clock speed changes, an improved graphics core, 16 lanes of PCIe 3.0 from the CPU and 24 lanes of PCIe 3.0 from the CPU. Kaby Lake is produced using the same 14nm manufacturing process, which broke Intel's tick-tock production model. Kaby Lake was announced in 2016, with its desktop CPUs launched in January of 2017, while OEM/mobile launched earlier in 2016. Since these are designed for mobile purposes, their TDP and boost speeds are lower than chips from the desktop family. We saw the flagship mobile processor as an i7-6970HQ with 4-core/8-threads, down to 2-core/2-threads again with Celeron-based processors. Core and thread counts ranged from 2-core/2-threads on the Celerons to 4-core/8-threads on the higher-performing SKUs, with clock speeds ranging from 2.2 GHz base clock to 4.2 GHz Turbo.Ī slew of mobile processors under the 6-series naming was also released and defined by the suffix on the end of the model. ![]() Skylake CPU's were based on the then-fresh 14nm fabrication process, using familiar i3/i5/i7-6-series branding for the Core models, G45x for Pentium models, and G39x for Celeron CPUs. Skylake was the "tock" in Intel's now-obsolete "Tick-Tock" production model, marking a brand-new architecture change (versus the "tick," which was traditionally a die-shrink of an existing architecture). ![]() Back in 2015, Intel released their Skylake architecture that succeeded the short run of Broadwell-based CPUs. ![]()
