Intel Core Ultra 7 355

The Core Ultra 7 355 is a Panther Lake laptop chip built on Intel's 18A process, soldered to the motherboard, so you pick it by picking the laptop. It has 4 performance cores and 4 low-power efficient cores, 8 threads in total. The performance cores run from 2.3 GHz up to 4.7 GHz and the low-power cores up to 3.5 GHz. It supports LPDDR5x-7467 or DDR5-6400 memory in two channels, up to 128 GB, along with Thunderbolt 4 and PCIe 5.0 storage.

Four full performance cores make the 355 feel quick in browsing, office apps, video calls and photo editing, and the low-power cores handle light background work to save battery. It has fewer total cores than H-series Panther Lake chips, so long renders and big code builds are slower than on those. Intel rates it at 25 W base power, 12 W minimum and up to 55 W turbo, which lets laptop makers tune it for either quiet thin designs or a bit more sustained speed.

The integrated Intel Graphics has 4 Xe-cores running at up to 2.5 GHz, with ray tracing support and up to 4 displays including 8K over DisplayPort. It handles 4K video, creative apps and lighter games at modest settings, but it is not the larger Arc B390 found in Core Ultra X models. The NPU is rated at 49 TOPS, above the 40 TOPS Copilot+ PCs require, so it can run Copilot+ and Windows Studio Effects features locally.

The Core Ultra 7 365 is its closest sibling, with the same 8-core layout and a slightly higher top boost. Against the older Core Ultra 7 155U, the 355 adds a much stronger NPU and a newer process. The Core Ultra 7 258V from the Lunar Lake generation also targets Copilot+ thin-and-lights, with on-package memory and Arc graphics. From AMD, the Ryzen AI 7 350 and Ryzen AI 7 450 are the direct rivals, with 8 cores and 16 threads and Copilot+ class NPUs. The comparison pages below show each spec side by side.

Yes, if you want a modern thin-and-light laptop with Copilot+ support, good battery life and responsive everyday speed. It suits business users, students and travelers well. If you edit video, compile code or play games often, a Core Ultra X or H-series model with more cores and Arc graphics is a better fit. Look for at least 16 GB of memory, since the graphics share it.
