Title: Intel Panther Lake CPUs bring up to 16 new cores, 30% better efficiency, and next-gen Xe3 iGPU
Post by: Redaktion on October 09, 2025, 15:00:23
Intel has officially unveiled the Panther Lake CPUs, designed for efficiency-focused laptop designs. The Panther Lake series consists of three main SKUs, with the top-end model featuring 16 cores, while the entry-level SKU is limited to eight. All three SKUs also bring new Xe3 Arc Celestial iGPUs.

Sounds pretty good, but...

QuoteIntel claims that the top Panther Lake SKU offers >10% faster single-core performance than Lunar Lake and Arrow Lake CPUs at "similar power". The multi-core performance increase is much bigger, as Intel touts a >50% increase in multi-core performance vs Lunar Lake and Arrow Lake at "similar power". Hyperthreading remains absent.

All the comparisons mention gains over Lunar Lake and Arrow Lake as if they had the same performance/efficiency. When Intel makes claims like this, they sound like standard meaningless marketing fluff.

Also, Thunderbolt 4? Only one PCIe x4 Gen 5 and only on the top model? Seems like Intel is quite behind in chip connectivity compared to Apple

It's not that hard to understand tbh. It has 50% more performance than Lunar Lake at similar power of Lunar Lake, and 50% more performance than Arrow lake at similar power of Arrow Lake. So at the power limit of Lunar Lake it's faster than Lunar Lake, and at the power limit of Arrow lake it's faster than Arrow lake.

Also, if you are not blind, the "midrange" sku has 12xPCIe 5.0, it's in the figure. Thunderbolt 5 controllers are still too big to be integrated into the chip, so it will depend on laptop OEMs to use discrete controllers.
