Intel is reportedly expanding its Core Ultra 300H Panther Lake mobile CPU lineup with another 16-core model, clocked slightly lower than the flagship chip. The company is also said to be working on an entry-level Wildcat Lake CPU that lacks the Ultra designation.
According to tech site VideoCardz, Intel is adding a new option to its Panther Lake lineup called Core Ultra X9 387H, featuring 16 cores split into four P-cores, eight E-cores, and four LP-cores. This means this chip will be identical to the flagship Core Ultra X9 388H in terms of core specs, mainly differing in boost frequency, which maxes out at 5GHz on the new model, against 5.1GHz on the 388H.
Regarding integrated graphics, the ‘X’ in this rumoured new CPU’s model name suggests this model will feature the same Arc B390 iGPU found in the 388H. The Arc B390 iGPU boasts 12 Xe3 cores clocked up to 2.5GHz, and our Panther Lake GPU benchmarks showed it was powerful enough to compete with some discrete mobile GPUs.
Since the core and iGPU configurations are expected to be identical to those of the 388H, frequency seems to be the only difference. Given that 100MHz is hardly a differentiating factor, laptop makers could pair the Core Ultra X9 387H with slower RAM to carve a larger gap between it and the 388H, helping to reduce costs.
VideoCardz also indicated that this unit will be consumer-only, with no support for Intel vPro enterprise management and security features, unlike some Core Ultra X7 CPUs, which are targeted towards businesses. However, support for SIPP (Intel Stable IT Platform Program), which guarantees no design or firmware changes for a defined period, remains.
Panther Lake aside, Intel is also expected to add a Core 300 Series CPU to its upcoming Wildcat Lake series, named Core 3 304. As the lack of Ultra branding in its name implies, this chip should be an entry-level CPU, targeting budget laptops and education devices. While no specs have been leaked for this specific model, a previously released presentation slide about the Wildcat Lake Core Series 3 chips shows six cores, comprising two Cougar Cover P-cores and four Darkmont LPE-cores. As for the iGPU, it looks as though it will just have a pair of Xe3 cores.
Previous rumours indicated that Wildcat Lake CPUs could launch in the first half of 2026, perhaps at Computex. Until then, we can only guess what the lineup will look like.
