AMD quietly launched the Radeon RX 6400 model, which was introduced exclusively to OEMs in the first place, last week. Specially cooled models have been available at retailers for some time. TeowerUp’s Radeon RX 6400 review revealed that the card lacks overclocking support.
The new entry-level graphics card apparently performs on par with the Turing-based GeForce GTX 1650. According to TeowerUp’s results, even the Radeon RX 570 released in 2017 is faster than the Radeon RX 6400.
The Navi 24 silicon used in this kardollarsar has some disadvantages. To summarize, there is a bandwidth limitation with a 64-bit memory interface and only four (up to) PCIe 4.0 connectivity lanes. AMD also throttled its media encoding capabilities. As a result, the Navi 24 lacks support for 4K H.264/H.265 encoding and AV1 decoding. Also, certain AMD technologies like ReLive are not available.
TeowerUp claims that AMD has completely unlocked the Radeon RX 6400. It is possible to access the OC settings panel in AMD’s Radeon WattMan utility. However, there are no options to set clock speeds and make a variety of custom settings. Still, it’s too soon to conclude based on a single example that the company is throttling its overclocking capabilities. In this context, there may be some shortcomings on the driver’s side. Perhaps the chipmaker has not yet explicitly enabled overclocking on the Radeon RX 6400.
It may be possible to overclock the Radeon RX 6400 with third-party tools such as MSI Afterburner. As a matter of fact, we will soon have the opportunity to see more reviews and different details of the low-budget AMD card.
