Intel Core Ultra 7 251HX

Intel Ultra 7 251HX

Intel Core Ultra 7 251HX är en mobil high-end CPU för bärbara speldatorer baserad på Arrow Lake-arkitekturen. Den erbjuder 18 kärnor bestående av 6 av de 8 snabba prestandakärnorna med upp till 5,1 GHz och 12 av de 16 mindre effektivitetskärnorna med upp till 4,5 GHz klockfrekvens. Processorn har tillgång till 30 MB L2-cache och 30 MB L3-cache och specificeras med en TDP på 45 watt.

SoC:n integrerar en liten dedikerad NPU kallad AI Boost med 13 TOPS (Int8) och har inte stöd för vPro. Den integrerade minnesstyrenheten stöder upp till 256 GB DDR5-6400 (dubbelkanal, ECC som tillval). Den integrerade GPU:n (iGPU) är ett litet Intel Graphics-grafikkort med fyra Xe-kärnor som körs i 300 - 1800 MHz.

Prestanda - High End

På grund av de 18 kärnorna och den höga klockfrekvensen bör prestandan ligga mellan Core Ultra 7 245HX och Ultra 7 255HX i high-end-utbudet av mobila processorer. Prestandan bör därför vara tillräcklig för alla krävande applikationer och spel under 2016.

Produktion - TSMC och Foveros

Arrow Lake-HX-chipen är baserade på desktopchipen Arrow Lake-S och består av flera chiplets. CPU-delen tillverkas hos TSMC med hjälp av den moderna N3B-processen (3 nm). GPU:n kommer också från TSMC i N5P-processen. SoC och I/O-tile tillverkas i TSMC:s N6-process. Basplattan tillverkas av Intel i 22nm-processen och bär de enskilda chiplets tack vare Foveros 3D-paketering.
