Intel Core i7-1255U

► remove from comparison Intel i7-1255U

Der Intel Core i7-1255U ist eine High-End Notebook-CPU auf Basis der neuen Alder-Lake-Architektur, die im Januar 2022 vorgestellt wurde. Die CPU basiert auf den Alder Lake-M Chip (für die U-Serie) und bietet 2  Performance Kerne (P-Kerne, Golden Cove Architektur) und 8 Effizienzkerne (E-Kerne, Gracemont Architektur). Die P-Kerne unterstützten Hyperthreading (daher gemeinsam 12 Threads) und takten von 1,7 bis 4,7 GHz. Die E-Kerne takten von 1,2 - 3,5 GHz und sollen eine vergleichbare Performance wie alte Skylake Kerne bieten (z.B. i7-6300HQ). Im Vergleich zum i7-1265U (schnellste U-Serie CPU zum Launch), bietet der 1255U um 100 MHz geringer getaktete CPU Kerne und nur vPro "Essentials" Features.

Performance

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.

Grafikeinheit

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.

Features

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).

Leistungsaufnahme

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).
