Intel has pulled the curtain on the 12th Gen Core HX series mobile processors, revealing the next generation of CPUs aimed at high-end gaming laptops and mobile workstations. The line-up includes seven SKUs, all supporting DDR5 memory, PCIe 5.0 and overclocking, delivering desktop-like performance in a portable format.
Based on the same silicon as the 12th Gen Core desktop processors, the new HX chips bring memory overclocking and E-core overclocking to mobile platforms, allowing you to push your system further. Moreover, the new chips also support XMP 3.0 and feature the new Dynamic Memory Boost feature to improve performance further.
As the leaked material showed us, there will be seven SKUs with up to 16 cores (8x P-cores and 8x E-cores) and 24 threads that can boost up to 5.0GHz. In addition, the chips feature plenty of PCIe lane support, including x16 PCIe Gen 5.0, x20 PCIe 4.0, and another x12 PCIe 3.0 lanes. The new processors also support up to 128GB DDR5-4800 memory, as well as DDR4-3200 or LPDDR4-4267 with ECC.
Foe integrated graphics, these CPUs ship with a Xe iGPU with up to 32 EUs. Users getting a system equipped with one of these CPUs may also benefit from Wi-Fi6E (Gig+) support and up to 2x Thunderbolt 4 controllers.
Based on Intel's benchmarks, performance will be significantly superior to the i9-11980HK. The new flagship CPU (i9-12900HX) will be 45% faster in media and entertainment workloads. Product development is the field where the new processors will shine brightest, offering +111% performance compared to the older i9 chip. As for life sciences, financial services and energy workloads, performance improvement over the 11th Gen Core i9 chip ranges between 72% and 82%. Performance should also be better in gaming, but don't expect any three-digit gains.
The first laptops equipped with these processors will be launching soon from the likes of Asus, Dell, Lenovo, MSI, Gigabyte and HP.

KitGuru says: Laptops with these HX processors won't come cheap, but the performance gains might be worth the cost over going with an older laptop model. Are any of you planning on getting a new laptop this year?
