The firmware reportedly fixes the TDP at 75W.
However, the TDP is substantially lower, given the compact form factor.
In addition, it arrives with four 16Gb Micron GDDR6 memory modules. Therefore, it would seem that HIS (Hightech Information System Limited) is the manufacturer behind the Radeon RX 6600 MXM.Īccording to the Redditor, the AMD driver detects the MXM as a vanilla Radeon RX 6600, so the number of stream processors is intact. Furthermore, an integrated OnSemi 55A power stage administers each phase, as SurfaceDockGuy reckons. Therefore, It's plausible that seven phases power the Vcore, whereas the remaining three phases cater to the GDDR6 or SoC. The Redditor noted that the Radeon RX 6600 MXM utilizes a 10-phase power delivery system with what appears to be two NCP81022 4+1 voltage controllers in tandem. AMD's Navi 23 silicon, which measures 237 mm², resides at the heart of the Radeon RX 6600.
