Intel i9-9900K explained: The road to 5GHz
Intel has released its new line of desktop processors, including the i9-9900K, an eight-core CPU which can boost up to 5GHz. These chips are certainly fast, but they also showcase some of the challenges Intel and entire chip industry has had in crafting speedier processors. In the 2000s, most people would have predicted we'd have 5GHz chips by around 2008. Though the first 5GHz chips did finally appear in 2013, they were outperformed by most other high-end chips on the market. So how can a processor that runs faster perform worse than a slower chip, and how fast will the i9-9900K really be?
Lenovo's new ThinkPads pack 8th-gen Core CPUs and slimmer designs
Lenovo just revamped the lion's share of its ThinkPad lineup, and it's good news if you want a speedy portable that won't weigh down your laptop bag -- or if you're privacy-conscious, for that matter. Its new ThinkPad X, T and L models have all made the switch to faster eighth-generation Intel Core processors while sporting slimmer, lighter bodies. The 12.5-inch X280, for example, is 15 percent thinner (0.69 inch) and 20 percent lighter (2.6 pounds) than its predecessor. There's also a new 13-inch L-series (the L380) for people who want a no-frills pro laptop in a more portable design than the 14- and 15-inch versions.
What is Intel Coffee Lake?
Intel's 8th-generation "Coffee Lake" CPUs are now on the market. These chips come with a modest bump in CPU frequency, but the big news is that Intel is finally adding 6-core processors to its mainstream i7 and i5 lines. More cores means these chips will perform better at tasks that benefit from multithreading, such as content creation and data processing, and the increase in frequency and cores will give a boost to gaming frame rates. Intel used to release chips on a "tick-tock" cycle that saw every release alternate either a new design, or a new manufacturing process - called a "node." A new process node, like moving from 45nm to 22nm, means smaller transistors and a faster or more power-efficient chip. But manufacturing challenges made tick-tock falter a few years ago, and now new releases are much harder to predict. "Coffee Lake" is the fourth chip Intel has released at 14nm, and the third based on the "Skylake" design from 2015. New designs and nodes are coming, but we'll probably have to wait until they arrive in 2018 to see a big jump in performance.
Intel will unveil 8th-gen Core processors on August 21st
Intel's 7th-generation Core processors still feel relatively young, but the company is already poised to talk about their successors. The chip designer has announced that it will premiere its 8th-generation Core CPUs on August 21st, complete with a livestream on Intel's Facebook page. The company is unsurprisingly shy on technical details, but it promises previews of PCs built on 8th-gen chips as well as a demo from a VR creator. As it stands, there's already some idea of what to expect.
Intel's 8th-gen Core processors won't be revolutionary
It's clearer than ever that the days of tick-tock Intel chip upgrades (new process one generation, new architecture the next) are long gone. Intel has revealed that its 8th-generation Core processors, due in the second half of 2017 will once again be built on a 14-nanometer process -- yes, for the fourth time in a row. The company is shy on what these new chips will entail, but it's claiming that it'll manage another 15 percent performance improvement (in SysMark tests, anyway) like it did with the 7th-generation Core designs you see now.
