Intel may have the first 16-core laptop CPU

By

According to a freshly leaked benchmark, Intel may be about to set new standards in high-end gaming laptop performance. The upcoming Intel Core i9-12900HX mobility chip has been benchmarked and returned fantastic results.

Although it looks like the Core i9-12900HX may swiftly become the best processor found in laptops, this kind of power doesn’t come without a potential downside — the laptop’s battery life.

The processor, spotted in the Geekbench database, will certainly mark a first for Intel once it’s released. It will be the first 16-core, 24-thread Intel laptop CPU on the market. Considering that this is an Alder Lake processor, it will feature the usual hybrid architecture, translating to eight performance cores and eight efficiency cores. The base clock was rated at 2.49GHz, with the boost clock going as high as 4.88GHz, which means that the CPU may be able to hit 5.0GHz.

The Intel Core i9-12900HX was found inside the upcoming Lenovo 82TD laptop and accompanied by an equally powerful graphics card, the Nvidia GeForce RTX 3080 Ti, in its laptop form, as well as 32GB RAM. The HX-series also comes with an integrated graphics card of its own, and this particular model has 32 Xe-LP GPU cores. Realistically, no one is ever going to use those, as a high-end processor is unlikely to find itself in a setup without a discrete GPU.

The upcoming Core i9-12900HX is an upgrade over its closest cousin, the Core i9-12900HK, which comes with 14 cores and 20 threads. This chip will likely end up at the top of Intel’s laptop lineup, and the benchmark results are here to confirm that. It scored 1,921 in single-core and 15,974 in multi-core tests. How does that match up against similar chips?

This CPU manages to beat every single processor in the multi-core benchmark, leaving AMD Ryzen 9 6900HX far behind with a score of just 10,151. It also outperforms the Core i9-12900H by a smaller margin, although it loses to the Core i9-12900H in single-core tasks by a very small margin. However, once more benchmarks are out, these results may still change.

According to Wccftech, this processor may actually be the full desktop chip that has undergone some optimizations to make it viable for laptops. Some of those adjustments would have certainly included power consumption and efficiency, but beyond that, the Core i9-12900HX is still a power-hungry chip with a TDP of 55 watts. Combine that with the RTX 3080 Ti, which can have a TGP of up to 175 watts in its best configurations, and we have a laptop that is unlikely to enjoy a long battery life.

No official information about the potential battery life of the Lenovo 82TD has emerged as of yet, but with such powerful components, frequent charging is most likely going to be necessary. This would make gaming on the go difficult — but poor battery life is often the price to pay for a high-end gaming laptop, so this won’t be a first.

Whenever the Lenovo 82TD is released with all of these outstanding components inside, it will undoubtedly be demanding in terms of the power bill and the initial expense. However, for a top-of-the-line laptop with Intel’s first 16-core mobile CPU inside, it just might be worth its presumably high price tag and the high power consumption that will follow.

Intel just launched the ‘world’s fastest’ CPU
Intel's 14900K CPU socketed in a motherboard.

Intel just announced a new CPU that is bound to rank high among some of the best processors -- the Intel Core i9-14900KS. A follow-up to the Core i9-14900K, the new CPU pushes the frequency out of the box beyond what any other chip can deliver right now, reaching a massive 6.2GHz. Intel estimates that it should deliver a sizeable upgrade over its predecessor, and we now know its specs, release date, and price.

The newly released Core i9-14900KS comes with 24 cores (eight P-cores and 16 E-cores) and 32 threads, 36MB of Intel Smart Cache, and a TDP of 150 watts. Much like the other CPUs in the Raptor Lake refresh lineup, it supports both DDR4 and DDR5 RAM, and it can handle up to 192GB of DD4-3200 MT/s memory or DDR5-5600. It can be paired with either a Z690 or a Z790 motherboard and offers 20 PCIe lanes, 16 of which are PCIe 5.0, while the rest are PCIe 4.0.

The upcoming Windows ARM laptops may have surprisingly powerful GPUs
A laptop and a camera on a table with a Qualcomm logo on the screen.

The next generation of ARM-based laptops and tablets with the new Snapdragon X Elite system-on-a-chip (SoC) won't be coming for a few more months, but new benchmarks already show its potential power in an important way. The results are surprising, and they show that Qualcomm's new ARM chip has as powerful a GPU as Intel's latest Core Ultra CPUs.

All of these new tests, which were initially spotted by WccfTech, were performed by Turkish YouTuber Erdi Özüağ in some pretty specific scenarios. Özüağ was able to push beyond the benchmark suites we've seen thus far and run the Proycon benchmark, as well as 3DMark and tests in Visual Studio Code and 7-Zip. He used a device with Qualcomm's reference design, as well as a laptop with an Intel Core Ultra 7 155H CPU. The device with the Qualcomm chip was running at 28 watts of power.

Intel CPU gaming crashes are causing an uproar
Intel Core i9-13900K held between fingertips.

Some of Intel's best CPUs may be having stability issues in Unreal Engine 4 and 5 games. According to reports from frustrated users, CPUs like the Core i9-13900K or the Core i9-14900K run into shader compilation issues in certain games, resulting in crashes. The community found a fix that seems to work for most people, but it's more of a workaround than a real solution.

Reports about these problems have been flooding various Steam forums and Reddit communities for months afterSebastian Castellanos on X (formerly Twitter) brought them to light. It appears that people are experiencing these problems primarily in UE4/5 games. During the initial shader compilation stage, the game crashes to desktop. Affected titles include Hogwarts Legacy, Fortnite, Remnant 2, Nightingale, and more.
