AMD’s Radeon RX 6600 Emerges In MXM Form Factor

One of the best graphics cards on the market, the Radeon RX 6600 comes in the unusual MXM (Mobile PCI Express Module) form factor.Editor surface dock guy (opens in new tab) somehow got a Radeon RX 6600 MXM, took it apart and looked inside. The MXM form factor is typically used inside laptops, but this particular Radeon RX 6600 module is probably for eGPU enclosures or servers that accept the format.

At the heart of the Radeon RX 6600 is 237 mm² of AMD’s Navi 23 silicon. Tandem. So it is plausible that 7 phases power the Vcore and the remaining 3 phases serve GDDR6 or SoC. Additionally, an integrated OnSemi 55A power stage manages each phase, as SurfaceDockGuy figures out. Therefore, HIS (Hightech Information System Limited) appears to be the manufacturer of the Radeon RX 6600 MXM.
