Intel Teases 40% Performance Boost With 8th-Gen Core i5, i7

There's no change to the chips' microarchitecture, but Intel claims they offer 40 percent more performance than their predecessors do.

Intel unveiled a new generation of Core i5 and Core i7 processors on Monday, promising a 40 percent performance improvement over its current crop of CPUs.

The four new chips represent the earliest beginnings of the Core family's eighth generation, and include two new Core i5 SKUs and two new Core i7 SKUs. They're U-series chips, which means they're destined for ultraportables and 2-in-1 convertible laptops or tablets. Each one has four cores and eight threads, with the top-of-the line Core i7-8650U achieving a maximum clock speed of 4.2GHz.

At the lower end is the Core i5-8250U, which runs at a maximum of 3.4GHz. All of the new chips boast the usual gaggle of Intel performance and security features, including Turbo Boost 2.0, Hyper-Threading, smart caches, and AES encryption. They also support Optane memory, a new technology Intel rolled out earlier this year to enable systems with conventional spinning hard disks rival the speed of PCs with solid state drives.

The chips are available now to OEMs and system builders, and major computer makers like Dell and Lenovo will likely announce new PCs with eighth-generation chips in time for the holiday shopping season.

Intel 8th Gen Core i5 Core i7

Missing from the chips is a new microarchitecture, the basic design of a microprocessor that defines everything from its caching capabilities to the construction of its transistors. The initial four chips are based on the existing Kaby Lake chip design, which uses a 14nm production process that is also found in the current sixth-generation Core lineup. A new 10nm architecture nicknamed Coffee Lake is in the works, although Intel has offered few details on its capabilities. Last week, the company also teased yet another architecture, called Ice Lake, which will use a second-generation 10nm production process that Intel refers to as 10nm+.

Also coming this fall are eighth-generation Core i3 chips, as well as Core i5 and i7 SKUs in the Y-series (for fanless PCs), H-series (for gaming laptops and mobile workstations), and S-series (for desktops) families.

Intel, ever tight-lipped about the specific design and manufacturing improvements that go into successive chip generations, didn't elaborate on how the eighth-generation Core lineup achieves its 40 percent performance gains. In a press briefing last week, however, the company did say that 25 percent of the performance boost comes from adding two more cores (seventh-generation Core i5 and i7 U-series chips have only two cores), while design and manufacturing improvements are responsible for the remaining 15 percent.

Intel's Core series has long been the preferred choice for powering consumer PCs, but the company is now facing increasing competition from AMD, which this year introduced its new Ryzen CPU lineup that rivals the Core's capabilities at comparable or slightly cheaper prices.

Managing Editor

I’m a managing editor at PCMag.com focused on PC hardware. Reading this during the day? Then you've caught me testing gear and editing reviews of Wi-Fi routers, printers, laptops, and tons of other personal tech. (Reading this at night? Then I’m probably dreaming about all those cool products.) I’ve covered the consumer tech world as an editor, reporter, and analyst since 2015.

I've covered most major consumer tech events, including CES, Computex, Google I/O, and IFA. I've also appeared on CBS News, in USA Today, and at many other outlets to offer analysis on breaking technology news.

Before I joined the tech-journalism ranks, I wrote on topics as diverse as Borneo's rainforests, Middle Eastern airlines, and Big Data's role in presidential elections. A graduate of Middlebury College, I also have a master's degree in journalism and French Studies from New York University.

The Technology I Use

While most people buy a phone or laptop and stick with it for years, I’m lucky enough to use devices based on Android, iOS, macOS, and Windows daily as part of my job. As a result, I cycle through lots of tech in addition to my IT-issue work laptop. (Yes, that's a ThinkPad.) Personally, I’ve also owned a lot of tech products both cutting-edge and cringeworthy, from the Nintendo GameCube and the original MacBook to the Palm m105 and the CueCat.
