Wow these numbers are actually nuts. 63% faster than 890M at 25 watts is insane! Along with Intels XeSS feature set and such, Radeon really needs to respond to this or risk losing the PC handheld space. Intel Core Ultra 300 “Panther Lake” reviews are here: CPU and iGPU gains analyzed |
Intel has a monster iGPU in its hands... and then goes and does the most stupid thing they could:
Panther Lake's limited number of PCIe lanes means you probably won't see any gaming laptops arriving with the 12-core Xe3 iGPU and a discrete GPU

You've read my breakdown on the architecture behind Intel's new Panther Lake processors. You've gone through every graphics benchmark that Andy has done with the range-topping Core Ultra X9 388H. Between the two of them, you've now decided that your next gaming laptop is going to be Panther Lake-powered and sport a big GPU from Nvidia, to go with Intel's big Xe3 tile. You're possibly going to be disappointed, then, to know that you're almost certainly not going to see any such lappies coming to market.
The reason why is quite simple: it all comes down to the number of available PCIe lanes in the platform controller tile. Intel has two variants of this chiplet: one with 12 lanes (four are Gen 5, eight are Gen 4) and the other with 20 lanes (eight Gen 4, twelve Gen 5). The important thing, though, is that every Core Ultra 300-series processor that has the big 12-core Xe3 iGPU uses the 12-lane platform controller tile.
Why?!

That's what they should do, which means that they'll likely do the wrong thing.
