Where are passive Radeon RX 6400?

53W TDP makes the Radeon RX 6400 the most economical graphics card of its current generation (RDNA 2, Ampere). This low power consumption not only eliminates the need for an additional cable, but also gives room for passive cooling. However, this does not take place. ASRock, Asus, Biostar, Gigabyte, MSI, PowerColor, Sapphire and XFX have already announced their own models, but none of the models (some brands have prepared even more) is passively cooled.

A little off topic, but also in connection with the Radeon RX 6400, it is worth noting that none of the manufacturers mentioned the OC model. Sure, it wouldn’t make much sense in this segment – but as the manufacturers competed to overclock the Radeon RX 6500 XT, the efforts of the Radeon RX 6400 are zero. Despite the fact that some coolers are obviously dimensioned for TDP and many times higher and overclocking would not mean additional costs for the manufacturer. It almost looks like the factory clocks were ticked by AMD.

However, it does not seem likely to stop the production of passively cooled cards. This would be conceivable if it entered into an exclusive passive card agreement with one of the manufacturers and the others did not receive this privilege. But not a single brand has a passive model, so the dog will not be buried here either.

However, anyone interested in a passively cooling model has a compromise at their disposal. There are semi-passive Radeons RX 6400, such as a two-fan card from Gigabyte (Radeon RX 6400 EAGLE 4G GDDR6). It has a larger heatsink, the fans of which remain switched off in 2D, during video playback even at low 3D load, and start up at a higher continuous load when the temperature would exceed the set limit.

It may be a good alternative especially in situations where the user is not sure he’s in his closet sufficient airflow to the card uchladí even at maximum load. Those who are looking for a purely passive solution, however, must look elsewhere in the current offer. For example, there is the passively made Palit GeForce GTX 1650 KalmX. However, it will be some percentage slower.
