Durch die 10 Kerne sollte die Multithread-Leistung deutlich oberhalb der alten 15 Watt 4-Kerner der Tiger Lake Serie liegen (wie z.B. dem i7-1160G7 ). Im Vergleich zu der H-Serie wird bei längerer Last aber der TDP die Leistung limitieren. Bei der Einzelkernperformance sollte der i7 dank der neuen Architektur auch ähnlich hoch getaktete Tiger Lake CPUs abhängen können.
Wie auch der Vorgänger, integriert Intel in Alder Lake eine Intel Xe basierende Grafikeinheit. Beim 1255P sind alle 96 EUs aktiviert und takten mit bis zu 1,25 GHz.
Wie auch Tiger Lake, hat auch Alder-Lake-P WiFi 6E und Thunderbolt 4 (4x) teilintegriert. Der integrierte Speicherkontroller unterstützt DDR5-4800, DDR4-3200, LPDDR5-5200 und LPDDR4x-4267. Der integrierte Gaussian and Neural Accelerator (GNA) ist nun in Version 3.0 verbaut. Die Media Engine Quick Sync 8 ist die selbe wie in Rocket Lake und unterstützt MPEG-2, AVC, VC-1 Decode, JPEG, VP8 Decode, VP9, HEVC und AV1 Decode. Der Chip unterstützt nur PCIe 4.0 (x8 for GPU und zwei x4 für SSDs).
Der Intel Core i7-1255U ist mit 15 Watt (PL1) TDP und 55 Watt (PL2) max. Turbo Power angegeben. Gefertigt wird der Prozessor im modernen Intel 7 Prozess (10 nm).
