Technical Specifications
Technical Summary
The ASUSTeK GA503QS motherboard, board number GA503QSNB1 RD2 EE1001 revision R1.0 dated October 13, 2020, is built around the AMD CPU FP6 platform supporting Cezanne/Renoir processors with a 35W TDP. Graphics are handled by an NVIDIA GN20E dGPU with GDDR6 VRAM. The system memory architecture combines DDR4 On-board 3200 MHz (8G or 16G) with a DDR4 SO-DIMM 3200 MHz (8G or 16G) across Channel A and Channel B. The embedded controller is an IT5125VG-192/CX, and the audio codec is a Realtek ALC289-CG. The charging subsystem uses an ISL9238BHRTZ-T slave charger. Networking is provided by a Realtek RTL8111H-CG LAN controller and a WIFI/BT module. The card reader is a GL9755-OIY04, and the HDMI interface uses an SN75DP159RSBR retimer.
