Alleged preliminary specs of Intel's Panther Lake-H CPUs show efficiency gains for the upcoming architecture.

Intel is throwing everything at the wall to see what sticks.

So Panther Lake is a sequel to Lunar Lake, a parallel effort to Arrow Lake and others, and is being broken up into multiple dies/chiplet configs unlike Lunar Lake (now with memory on package killed as Intel discussed before).

The final listing is for a seemingly lower-end eight-core chip with a configuration of 4+0+4. This will likely be the Core Ultra 300U chip, set to be used in entry-level devices or gaming handhelds. This configuration can run with a PBP of just 15W and an MTP of 44W under the 'baseline' power mode, while it boosts up to a similar 25W PBP and 55W MTP under the 'performance' mode.

It says 4+0+4Xe. Looks like a quad-core to me, not 8-core. Weird choice for Intel not to have any E or LPE cores, but it could easily be the fastest quad-core ever made.

Unless the leak is not even listing the 4x LPE cores, I guess. Which means the top 4P+8E would technically have 16 cores.

A 4P+0E would get trashed by a Lunar Lake apu. IPC uplift is only 10% max for Cougar Cove P cores. This config would only make sense as a new low end U class apu, with there also being 4P+4E(LPE) cores offerings to match Lunar Lake.

Panther Lake isn't really a Lunar Lake sequel, as it covers U and H class and doesn't have integrated memory. Lunar Lake is a weird one off product that is too dear to keep making.

The nice thing is Panther Lake gets X3 (Celestial cores) so should absolutely demolish Arrow Lake H's weak Xe based iGPU.

I think others have described it as the successor to Lunar Lake, even though it is split up into 2-3 classes. It will be the best choice for Intel handhelds. The memory on package is gone, Rest in Pat, but maybe you wouldn't even notice if Panther Lake ends up being paired with soldered memory in most ultrathin laptops anyway.

It's not taking over for Arrow Lake-H because it only has 4 P-cores. Although maybe the 4P+8E+4Xe version is intended to be paired with discrete graphics. But these chips will have to exist in parallel with Arrow Lake, and later Nova Lake-H (although one leak says only 4 P-cores for that too).

Wildcat Lake (presumed Alder Lake-N/Twin Lake successor) might end up looking more technically similar to Lunar Lake, with no E-cores and 4x LPE-cores that may not be able to access L3 cache. Wildcat Lake area/cost will be down from cutting 2x P-cores, most of the graphics, and memory on package which was said to be more expensive.

It's hard to find actual details about what is replacing what with Intel. Panther Lake is IMO a Meteor Lake replacement, not Lunar Lake. A 4P + 8E + 4LPE + 12 Xe3 would be highly competitive against 6P + 8E + 2LPE config of Arrow Lake IMO in multithreading, and it would be no contest graphically. 12 Xe3 cores would probably even obliterate AMD 890M 16CU igpu IMO.

Yeah, whatever they are doing with the coars, it's nice that Intel seems to be pushing the graphics hard. AMD has gotten a little complacent with its mainstream APU integrated graphics, although Strix Halo is something else entirely (and will be priced to match).

With only 4 performance cores I guess we'll never see a x86 mobile CPU beat the M4/M4Pro/M4Max and keep up with Apple Silicon?

There'll be Nova Lake H/HX for that. They'll be pretty impressive I suspect
