Title: First public Intel Alder Lake-P Core i9-12900HK leak surprises with 50% dip in multi-core scores compared to Apple M1 Max, 96-EU Xe iGPU on the anvil
Post by: Redaktion on November 10, 2021, 07:12:03
The first public appearance of the upcoming Intel Alder Lake-P 14-core 20-thread Core i9-12900HK powering a Lenovo Legion laptop has surfaced on Geekbench. This leak shows significantly lower single and multi-core performance than the closed leak we've seen recently. The benchmark also reveals that the Core i9-12900HK sports a 96-EU Xe Graphics iGPU.

That could be the test result of 8 E-cores, I'd love to have 8P + 4E instead of 6P + 8E in the flagship SKU. Tiger Lake Willow Cove cores have been proven quite good for gaming, having extra E cores only good for Ultrabook where battery life is a big concern, not gaming laptops with HK processors.
This's not to mention compatibility problem in quite a few games with E-cores that we've seen recently.

Probably this is a test while not plugged to power

You have also to consider that the laptop has only 8GB of RAM running in Single Channel this could strogly affects the performance.
By the way, 6P+8E is not a bad idea overall, 6P core in a laptop is enough to reach the maximung gaming performance. It could be better but after all they have made a "all-good" processor, Good Single-Core performance, Good Multi-Core Count (and probably also performance), Good iGPU, and probably good power consumption.
So, if in one hand it could be better have something like 8P+8E and 32EU for the GPU for the Gaming scenario, in the other hand you can still have an ultrabook like laptop (14-15") with strong CPU performance and good GPU performance.
There are not only gamer in the world.

e cores are the best, in laptops and desktop. they consume very little space and give you a lot of punch, more than what an equivalent 1 P cores with its HT would give you. Sure, for some specific cases you do need the P cores and you have 6 of them which I would say is plenty, but for the vast majority of tasks, the e cores are a great idea, plus they raise the overall efficiency of the platform.

Did Intel release a new security patch?

Probably unplugged.

On the other side, why they have so many e-cores and threads? I'm the only one who thinks we're getting into a core/thread-war, like the old mhz war?

I feel 16 cores  32 threads is more than enough for a non-workstation machine.

Gaming wise, regarding the cpu if one can beat/match the 8 zen2 cores consoles have it should be plenty power for the time being.

definitely thermal throttle.  250W on desktop is now problem but in a 1" or less laptop impossible to cool
