ASUS GeForce RTX 4090 ROG MATRIX PCB Dissected: Similar To STRIX With Added Functions & Less Coil Whine

wccftech.com:

The recently revealed ASUS GeForce RTX 4090 ROG MATRIX has been subjected to a thorough PCB dissection, courtest of overclocker & hardware enthusiast Der8auer.

The actual PCB design of the ASUS GeForce RTX 4090 ROG MATRIX is very similar to the RTX 4090 ROG STRIX. Some PCB units had the ROG STRIX label on the bottom, suggesting that the company made minimal changes in the design. The card given to Der8auer was one of the very first samples of the ROG MATRIX so that may explain why the label reads ROG STRIX.

However, there were some differences in terms of the components used. The ASUS GeForce RTX 4090 ROG Matrix now comes with new temperature sensors installed on the PCB in order to determine the actual temperatures in detail. This is beneficial since you can decide if you applied the new thermal pads appropriately by observing the temperatures of each part after you covered the memory module components with them.

ASUS has also changed the power stages, replacing Onsemi with MPS stages. There is no difference in the power rating as both are rated 70A. This may be done due to availability issues to ensure a smoother supply chain. Moreover, ASUS has also installed new inductors, reducing the "coil whine" noise significantly. This issue was faced with the ROG STRIX 4090 too, and don't worry, ASUS has also catered to this by including identical inductors in new units.

Tuning the graphics card within Boost Master made it reach over 3.7 GHz with some voltage and power adjustments but it capped out at 3780 MHz which is where the card artifacts. Since this is an early sample, we can expect the final retail units to feature slightly better clock speeds so we might just see hardcore LN2 overclockers reaching close to 4 GHz.
