Tiger Lake è il nome in codice di Intel per i processori Intel Core di undicesima generazione per dispositivi mobili basati sulla nuova microarchitettura Willow Cove Core, prodotta utilizzando la terza generazione del processo produttivo a 10 nm (denominato "10nm SuperFin")[1][2][3]. Intel ha annunciato il 5 agosto 2020 che avrebbe lanciato Tiger Lake il 2 settembre 2020 tramite webcast[4]. Tiger Lake sostituisce la famiglia di processori mobili Ice Lake rappresentando la fase di ottimizzazione nel modello di sviluppo PAO.

Tiger Lake include modelli quad-core e dual-core con un TDP configurabile tra 7 W e 28 W[1][2][3]. I processori Tiger Lake saranno alla base di alcuni laptop che rientrano nel programma "Project Athena 2.0" che saranno identificati dal logo "Intel EVO powered by Core"[1][2][3]. Il die quad-core misura 13,6 x 10,7 mm (146,1 mm 2), ovvero è il 19,2% più largo del die quad-core di Ice Lake, che misura 11,4 x 10,7 mm (122,5 mm 2 ) ma integra una GPU con 96EU contro 64EU del predecessore. Secondo Yehuda Nissan e il suo team, l'architettura prende il nome da un lago al di là di Puget Sound, Washington.

Cambiamenti rispetto ad Ice Lake

  • Core CPU Intel Willow Cove
  • GPU Intel Xe-LP ("Gen12") con un massimo di 96 unità di esecuzione con alcuni processori ancora da annunciare che utilizzeranno la GPU dedicata di Intel, DG1[1][2][3]
  • Decodifica hardware a funzione fissa per HEVC a 12 bit, 4: 2: 2/4: 4: 0; VP9 12 bit 4: 4: 4 e AV1 10 bit 4: 2: 0
  • PCI Express 4.0[1][2][3]
  • Thunderbolt 4[1][2][3]
  • USB4[1][2][3]
  • Memoria LPDDR5 su futuri modelli[5]
  • Tecnologia Deep Learning Boost (DL Boost) con nuove istruzioni DP4A per l'accelerazione dell'intelligenza artificiale nella GPU Xe[6]
  • Una nuova istruzione AVX-512: Vector Pair Intersection to a Pair of Mask Registers (VP2INTERSECT).
  • Miniaturizzazione della CPU e della scheda madre in un piccolo circuito stampato delle dimensioni di un SSD M.2
  • Supporta un singolo display HDR 8K a 12 bit o 4 display HDR 4K a 10 bit[1][2][3][5]
  • Dolby Vision con accelerazione hardware[1][2][3]
  • Tecnologia di controllo del flusso di applicazione per prevenire le tecniche di hacking della programmazione orientata al ritorno e della programmazione orientata al salto
  • Crittografia completa della memoria (RAM)
