Intel unveiled a new line of processors at its Vision event on Tuesday, May 10th. Part of the 12th Gen Intel family, the new 55W HX Series CPUs are designed to deliver the highest possible performance in a mobile form factor. at least according to Intel.
The flagship Core i9-12950HX lends some credence to the claim of being the first 16-core laptop CPU ever. Like other 12th Gen Alder Lake processors, it splits the cores into performance and efficient cores, and the chip can crank up to 5GHz. Like other processors in the HX series, it also has a power limit of 55 watts.
As you can see from the spec sheet above, Intel’s lineup doesn’t just focus on flagships. The Core i5-12450HX still has access to 55W to power a maximum boost clock of 4.4GHz and eight cores. This class of mobile CPU seems capable of competing with AMD’s recently announced Dragon Range chips.
In terms of performance, the new chips offer up to a 17% improvement in single-threaded performance and up to a 64% improvement in multi-threaded performance, according to Intel, compared to the last-gen Core i9-11980HK. These are Intel’s first-party benchmarks, and as always, we recommend waiting for third-party benchmarks before drawing any definitive conclusions.
Intel hasn’t provided any gaming comparison data, although the company said the Core i9-12900HX is capable of delivering up to 128 fps Far cry 6 and up to 149 fps in ForzaHorizon 5 when paired with a mobile RTX 3080 Ti. However, laptop gaming performance is largely dependent on the individual machine, so we recommend sticking to dedicated laptop tests rather than Intel’s benchmarks.
The new chips offer an increase in core count, but also new platform features. These include support for DDR4 and DDR5 memory, including ECC (Error Correcting Code) memory, as well as support for PCIe 5.0. Several chips also support Intel vPro, giving apps like Adobe Premiere Pro and AutoCAD ISV certification.
Like Intel’s previous mobile flagship, the Core i9-12900HK, the new chips support memory and core overclocking. You can manually optimize the efficient and powerful cores, overclock the memory and save the setup in an XMP 3.0 profile. Although all new chips support overclocking, some have “limited core OC” as stated in the table above. We reached out to Intel to clarify what limitations exist on these chips.
Intel emphasizes the importance of I/O in the new chips compared to its H-series processors. The chips support up to eight SATA 3.0 connections, 14 USB 2.0 and 10 USB 3.0 connections, and two discrete Thunderbolt controllers. This is made possible by the larger size of the HX-series processors, which are almost the size of Intel’s 12th Gen desktop chips.
HX chips should be arriving soon, but Intel hasn’t announced a firm release date. The company still showed several devices with the new chips, including the Lenovo Legion 7, the MSI GE77 Raider, and the Dell Prevision 7670.
