Intel’s Core i9-12950HX has 16 cores and 55 watts of power

Intel announces seven new mobile processors. The group, known as the “HX” line, includes two Core i5, three Core i7 and two Core i9 options.

Intel’s 12th generation mobile chips have not disappointed so far. We’ve seen significant performance gains over the previous generation, although battery life remained an area where the company often lags behind Apple and AMD. We don’t necessarily expect the new HX CPUs to go against that trend — they’re all about power.

Here’s the other side.

Four of the seven chips here have 16 cores and 24 threads (with eight performance cores and eight efficiency cores). The flagship chip, the Core i9-12950HX, is the real beast. It operates at a base power of 55W, with a maximum turbo power of up to 157W. The performance and efficiency cores have maximum turbo frequencies of 5.0 GHz and 3.6 GHz, respectively, with base frequencies of 2.3 GHz and 1.7 GHz, respectively.

The chip is eligible for Intel’s vPro management platform.

Intel (unsurprisingly) claims massive performance improvements over previous generations. Internal testing of the Core i9-12900HX (which on paper looks just like the 12950HX but isn’t vPro capable) shows a 17 percent increase in single-thread performance over last’s Core i9-11980HK. years and 64 percent in multi-threaded tasks, as well as a wild 81 percent increase in 3D rendering performance.

Now we have (of course) leaked benchmarks of these chips, and while they don’t exactly match what Intel has tested, the results we have don’t seem too far off the mark. We are looking at a serious mobile power supply.

Intel also hinted which laptops will power these chips, and it’s an… interesting bunch. It includes powerful devices such as MSI’s GT77 Titan (which will feature the 12900HX, according to the charts), Gigabyte’s Aorus 17X and Asus’ ROG Strix Scar 17 SE. We also know that the 12900HX will appear in Lenovo’s upcoming Legion 7i

But there are also some ultraportable consumer devices on that slide, including Asus’ Expertbook B6 (a cousin of one of the lightest laptops ever made† We expect that to be one of the more efficient options here.

You only need one look at the spec sheet to understand that pure power is Intel’s priority. For many of the laptops here (the Titan, for example) that makes perfect sense. Gaming laptops are generally not known for their incredible battery life.

But these will be all power-hungry chips (especially if the desktop chips are any indication). And while a minuscule lifespan probably won’t be a deal breaker for anyone shopping in the MSI Titan category, it does make such a laptop look less and less attractive compared to a desktop. And an all-day battery makes laptops on the AMD side like the Asus ROG Zephyrus G15 much more viable to double as a personal or work device, which is already a hard sell on many Intel-powered portable machines that are becoming less than a few hours

That makes the Expertbook a particularly interesting choice. The Expertbook is a line known in the past for both its light weight and battery life. It’s not exactly the type of device we’d expect from a desktop-powered chip. Perhaps that indicates that some of these chips will be more efficient than they look, but we’ll have to wait and see when the units start hitting shelves.

Computex 2022 is just around the corner and these chips are coming just in time for a slew of new releases. We already know what companies like Asus and Lenovo are announcing, and more will follow in the coming weeks.
