Intel Core i7-7820HQ

Intel i7-7820HQ

L'Intel Core i7-7820HQ è un veloce processore quad-core per notebooks basato sull'architettura Kaby Lake ed annunciato a Gennaio 2017. E' il secondo modello per velocità della serie consumer al momento del lancio. Solo l'i7-7920HQ e l'Xeon E3-1535M v6 sono più veloci. Oltre ai quattro cores ha il supporto Hyper-Threading e gira a 2.9 - 3.9 GHz (4 cores fino a 3.5 GHz, 2 cores fino a 3.7 GHz), il processore monta anche una GPU HD Graphics 630 ed un controller di memoria dual-channel (DDR3L-1600/DDR4-2400). E' realizzato con processo da 14nm con transistors FinFET.

Architettura

Intel di base utilizza la stessa micro architettura rispetto alla Skylake, quindi le prestazioni per-MHz non differiscono. Il produttore ha solo rielaborato la tecnologia Speed Shift per una regolazione dinamica più veloce dei voltaggi e dei clocks, ed il migliorato processo 14nm consente frequenze maggiori unitamente ad una migliore efficienza rispetto al passato.

Performance

Grazie alla velocità clock superiore, le performance dell'i7-7820HQ sono leggermente superiori rispetto al precedente modello top Skylake Core i7-6920HQ (2.9 - 3.8 GHz). Le performance sono sufficienti anche per applicazioni molto pesanti e alla pari con i potenti processori desktop quad-core.

Grafica

L'Intel HD Graphics 630 integrata ha 4 Execution Units (come la precedente HD Graphics 530) gira a 350 - 1100 MHz. Le performance dipendono molto dalla configurazione della memoria; dovrebbero essere paragonabili ad una Nvidia GeForce 920M dedicata unitamente ad una veloce memoria DDR4-2133 dual-channel.

Diversamente dalla Skylake, la Kaby Lake ora supporta il decoding hardware per l'H.265/HEVC Main 10 con una profondità del colore da 10-bit oltre al codec Google VP9. I processori dual-core Kaby Lake, che sono stati annunciati a Gennaio, dovrebbero supportare anche l'HDCP 2.2.

Consumo Energetico

Il chip è realizzato con un processo in 14nm migliorato e con transistors FinFET, che migliora ulteriormente l'efficienza. Intel specifica ancora un TDP da 45 Watts, ma può anche essere ridotto a 35 Watts dai produttori di portatili (cTDP down). Questo ovviamente impatta sulle performance, in quanto il Turbo Boost non può essere mantenuto per periodi lunghi.
