⚙️ PRODUCT CHARACTERISTICS

BDPLANAR-type system board (FT491/FX390 NM-B891 Rev:2.0) with a factory-soldered Intel Core i5-8265U processor (Whiskey Lake-U, 14 nm, BGA1528, 4 cores / 8 threads, 6 MB cache, base clock 1.60 GHz, up to 3.90 GHz Turbo, 15W TDP) and integrated Intel UHD Graphics 620 (300 MHz base, up to 1.10 GHz dynamic).
