The first "8th generation" Intel Core processors roll out today: a quartet of 15W U-series mobile processors. Prior generation U-series parts have had two cores, four threads; these new chips double that to four cores and eight threads. They also bump up the maximum clock speed to as much as 4.2GHz, though the base clock speed is sharply down at 1.9GHz for the top end part (compared to the 7th generation's 2.8GHz). But beyond those changes, there's little to say about the new chips, because in a lot of ways, the new chips aren't really new.

Although Intel is calling these parts "8th generation," their architecture, both for their CPU and their integrated GPU, is the same as "7th generation" Kaby Lake. In fact, Intel calls the architecture of these chips "Kaby Lake refresh." Kaby Lake was itself a minor update on Skylake, adding an improved GPU (with, for example, hardware-accelerated support for 4K H.265 video) and a clock speed bump. The new chips continue to be built on Intel's "14nm+" manufacturing process, albeit a somewhat refined one.

takyon: Also at AnandTech. Where's 14nm++ Coffee Lake?

In the past we are used to a new numbered generation to come with a new core microarchitecture design. But this time Intel is improving a core design, calling it a refresh, and only releasing a few processors for the mobile family. We expect that Intel's 8th Generation will eventually contain three core designs of product on three different process design nodes: the launch today is Kaby Lake Refresh on 14+, and in the future we will see Coffee Lake on 14++ become part of the 8th Gen, as well as Cannon Lake on 10nm.

[...] So when is Coffee Lake on 14++ (or Cannon Lake) coming? Intel only stated that other members of the 8th Generation family (which contains Kaby Lake Refresh, Coffee Lake and Cannon Lake) are coming later this year. Desktop will come in the autumn, and additional products for enterprise, workstation and enthusiast notebooks will also happen. As for today's 8th Generation U-series announcement, Intel tells us that we should start seeing laptops using the new CPUs hit the market in September.

Intel Releases 8th-Generation "Coffee Lake" CPUs, Including Quad-Core i3 Chips 6 comments

At the top of the stack are two Core i7 Coffee Lake processors. In previous generations 'Core i7' meant that we were discussing quad-core parts with hyperthreading, but for this generation it moves up to a six-core part with hyperthreading. The Core i7-8700K starts at a 3.7 GHz base frequency and is designed to turbo to 4.7 GHz in single threaded workloads, with a thermal design power (TDP) of 95W.

[...] In the middle of the stack are the Core i5 processors, with the new generation matching the 'same configuration without hyperthreading' philosophy that followed in the previous generation. The two Core i5 parts operate at lower clockspeeds compared to the Core i7, and perhaps more so than we are previously used to, especially with the Core i5-8400 having a base frequency of 2.8 GHz. Intel sampled us the Core i5-8400 for our review, because it hits an important metric: six cores for under $200.

[...] It is interesting to note that in the last generation, Intel had processors with two cores and two threads (2C/2T), two cores with hyperthreading (2C/4T), quad cores with four threads (4C/4T) and quad cores with hyperthreading (4C/8T). This layout had staggered, regular steps. With the move to 6C/12T on the high-end Core i7, and 6C/6T on the mid-range Core i5, Intel completely skips the 4C/8T parts and moves straight to 4C/4T on the Core i3. This is likely because a 4C/8T processor might overtake a 6C/6T part in some multi-threaded tests (it would also explain why moving from a previous 4C/8T Core i7 processor to a 6C/6T Core i5 8th generation is not always an increase in performance).

However at the bottom of the stack are the 4C/4T Core i3 processors, where Intel is pushing out an overclockable Core i3 processor again. This is a little bit of a surprise: in our testing of the previous generation overclockable Core i3, the fact that it was dual core was a setback in a lot of testing. With the Core i3-K now being quad-core, and overclocking it to try and beat a six-core chip for less money, for certain things like gaming we might see less of a difference between the two.

Intel's Ice Lake Architecture Will be "10nm+" 19 comments

Intel will announce its Coffee Lake processors on August 21. They will be the last generation of 14nm(++) Core processors before 10nm Cannon Lake and Ice Lake, which is described as using a "10nm+" process:

In an unusual move for Intel, the chip giant has ever so slightly taken the wraps off of one of their future generation Core architectures. Basic information on the Ice Lake architecture has been published over on Intel's codename decoder, officially confirming for the first time the existence of the architecture and that it will be made on Intel's 10nm+ process.

The Ice Lake processor family is a successor to the 8th generation Intel® Core™ processor family. These processors utilize Intel's industry-leading 10 nm+ process technology.

This is an unexpected development as the company has yet to formally detail (let alone launch) the first 10nm Core architecture – Cannon Lake – and it's rare these days for Intel to talk more than a generation ahead in CPU architectures. Equally as interesting is the fact that Intel is calling Ice Lake the successor to their upcoming 8th generation Coffee Lake processors, which codename bingo aside, throws some confusion on where the 14nm Coffee Lake and 10nm Cannon Lake will eventually stand.

[...] Working purely on lithographic nomenclature, Intel has three processes on 14nm: 14, 14+, and 14++. As shown to everyone at Intel's Technology Manufacturing Day a couple of months ago, these will be followed by a trio of 10nm processes: 10nm, 10nm+ (10+), and 10++.

Tick Tock has given way to plus signs everywhere.

Coffee Lake will include the first mainstream 6-core chips from Intel, including the Intel Core i5-8600K and i7-8700K.

    Have you *seen* the review of the 8550U on Notebookcheck? It's a 15W chip with 4 core and 8 threads that manages to stay neck and neck with last generation's 45W i5-6300HQ quad-core, or the Ivybridge i7-3610QM! The uarch may be old, but that also means it's mature and well-optimized. Coming from the forum's resident AMD fangirl, I really want to get my hands on a machine with that kind of firepower.

        You can jerk off to Intel all you want, but it took them 10 years to double performance-per-dollar. A shame they didn't stick a magnet in Moore's ass and rolled a coil around his coffin. Would have saved them millions in utility bills.

          People simply stopped buying desktops. Oh some people still snag them. But most of the business world went to laptops and low power devices. The datacenters also said 'cant buy any more topped out on power'. ARM is decimating Intel. They know it. Then AMD tripped on their face about 20 times during that time. So Intel basically being the only game did nothing. AMD got its crap together and suddenly 'interesting' chips flow from the Intel group again.

          Most CPUs have a out to memory and back of 200+ cycles. You can increase the speed all you like on the CPU. Memory/heat is the bottleneck.

          The CPU I am looking at is about 15%-30% better IPC than what I bought 5 years ago at a slightly lower TDP. As I am a laptop guy now I am looking more for the GPU/screen upgrade. Probably a pascal nVidia 1070 chipset. Plus the extra speed in memory will not hurt either from 1800 to 2400.

          Skip the X line they basically a marketing speed bin of some select chips. Not worth the money.

          You can jerk off to Intel all you want, but it took them 10 years to double performance-per-dollar
          You can argue it too AMD even longer. The last time they were competitive with Intel was 2003.

      No reason not to just buy Intel this generation either. me_cleaner can excise some of the worst features on the Intel side, but the GPUs are FUBAR'd on both sides now.

      Since the hardware is going to spy on you either way, and unless you're running unlocked (non-TrustZone or unsigned TrustZone capability) ARM chips there aren't any alternatives in the notebook or desktop realms at consumer reasonable prices other than Intel/AMD.

          The word girl can also be used to refer to adult women depending on context. Language is silly like that.
