Panther Lake leaked: Intel’s new CPU series brings 12 models, but falls short of expectations

You could call it a cautious restart or a desperate attempt to make up ground: With the upcoming Panther Lake series, Intel wants to prove once again that it has not completely lost its technological footing. A recent leak on Chiphell now shows the presumed SKUs of the first wave and reveals more questions than answers.

According to the leak, a total of twelve models are to be released at the start. The series is divided into three segments: four models from the Core Ultra X series (performance segment), four regular Core Ultra models and four energy-saving variants from the PTL-U series. The “X” segment naturally attracts the most attention. These models (e.g. Core Ultra 9 X388H, Ultra 7 X368H) are based on a hybrid architecture with four performance cores (Cougar Cove), eight efficiency cores (Darkmont), four low-power cores (Skymont) and up to 12 Xe3 graphics units. The latter is remarkable, because while earlier leaks suggested that only top models such as X7/X9 have 12 Xe3 cores, the current leak confirms that even the Core Ultra 5 X338H model appears in the “X” series, albeit with only 10 GPU cores. A logical demarcation therefore still seems to exist: full Xe3 power only for the top third.

The situation is different in the normal Ultra lineup: 4P 8E 4LP are still used here, but the GPU is neutered to a meagre 4 Xe3 cores – a clear step backwards, especially compared to the Ryzen A8000 series, where AMD now relies on beefed-up Radeon units. Intel has made the biggest cuts to the PTL-U models – the classic low-power chips for ultrabooks. E-cores are completely dispensed with here: The chips combine two to four P-cores with four LP-E cores, presumably to reduce power consumption. Graphically, 4 Xe3 cores are retained. While “Cougar Cove” is no surprise as the P-core heir to Redwood Cove, the use of three different core architectures is striking – especially the integration of the energy-efficient Skymont cores as a separate third rail. At first glance, this seems innovative, but it has a bitter aftertaste: Intel is making it clear that performance, efficiency and mobility cannot be elegantly combined in one core profile – you have to work with three different designs to achieve the desired load distribution. The design is technically interesting, but also an indication of fragmented priorities.

Another mystery is the model name. The leak shows variants such as “Core Ultra 7 X368H”, other leaks prefer “Core Ultra X7 368H”. This inconsistency either looks like uncoordinated internal chaos – or is simply a sign that Intel itself has not yet decided on a final naming structure. Both would be problematic, because customer communication and market positioning start with a clear name. The leak confirms this: Intel is bringing out the big guns. Twelve models, three architecture types, a wide spread of GPU capacities. But despite all the impressive specifications, a pale aftertaste remains. This is because a lot of things seem reactive, not proactive – a firework display of SKUs that compensates frantically rather than strategically convincing. The fragmented GPU strategy in particular is likely to be a nightmare for OEMs and developers. If you want to work with Xe3, you have to take a close look – there are even significant differences between X5 and X9. There is no trace of uniformity.

Panther Lake shows: Intel is not technologically dead – but caught in an arduous balancing act between past and future. If you want to have a say in every price and performance level, you risk not really shining anywhere.
