According to screenshots shared on social media, the Panther Lake family will include four standard Core Ultra 3X5H models, four Core Ultra X 3X8H chips and another four low-power PTL-U parts.

The leak also points to a new lower-end X-series SKU called the Core Ultra 5 X338H, or possibly Core Ultra X5 338H depending on how Intel decides to structure the naming.

The Core Ultra 5 X338H will reportedly have only ten Xe3 GPU cores. This contradicts earlier rumours that all X-series chips would include twelve GPU cores, suggesting that only the higher-end Core Ultra 7 and 9 X models will carry the full configuration.

For the regular Panther Lake lineup, the graphics downgrade is even greater. The Core Ultra 5, 7 and 9 3X5H models are expected to retain the same CPU core counts but feature just four Xe3 GPU cores. The low-power Core Ultra 3, 5 and 7 3X0U chips will also use between six and eight CPU cores paired with the same four-core GPU setup.

The leak, from Chip Hell indicates there will be roughly a dozen Panther Lake SKUs in the first batch, hinting that Intel is maintaining its complicated product segmentation rather than streamlining the range.

It confirms some earlier reports about GPU configurations and CPU layouts, though one question remains unresolved: whether the company will brand the chips as “Core Ultra X5/X7/X9” or “Core Ultra 5/7/9 X.”

If accurate, the Panther Lake lineup will show Intel trying to balance its architectural advances with efficiency and integrated graphics performance, even if its naming strategy continues to confuse buyers.

As always, none of this is official yet, so the specifications should be taken with a grain of salt until Intel’s formal announcement.
