For the people expecting this to be a CPU with a big-little architecture or NVIDA GPU, it was both.

The Lenovo ThinkPad P1 Gen 8 review unit is equipped with an Intel Core Ultra 7 255H "Arrow Lake H" Processor, 64GB of LPDDR5-7467 memory, NVMe storage, and NVIDIA RTX Pro 1000 graphics. The Intel Core Ultra 7 255H consists of 16 cores between six P cores, 8 E cores, and two LPE cores. The Core Ultra 7 255H has a 28 Watt base power rating and 115 Watt maximum power rating.

There used to be performance issues with mixed P and E cores and Linux, but I thought that was solved. Could that still be causing this discrepancy?

Is it a new architecture that is not yet fully utilized by Linux but we can expect it will be soon?

[–] qaz@lemmy.world 10 points 2 days ago

It will probably be faster in the future under Linux, but I'm no kernel developer

Understanding what to do with P and E (and LPE?) cores in general I assume has been solved, but I would guess that each new CPU model comes out needs to be configured so that the kernel knows what arrangement of cores it has and maybe that hasn't been done yet because the chip is so new?
