Last week, AMD quietly launched its Radeon RX 6400, a budget graphics card designed for those with low-profile PCs. However, a new review of the card reveals that it has no official overclocking support.
It looks like AMD has disabled the only way for owners to boost the power of their Navi 24-based GPU, according to a TechPowerUp review of the new card. And since it’s an even weaker version of the RX 6500 XT, it could pose a problem for those looking to overclock the graphics card for a bit more power.
During its review, TechPowerUp found that AMD had completely locked the RX 6400 into the Radeon WattMan utility. While it still has the OC settings panel, there are no sliders to adjust clock speeds in its custom settings as there would normally be.
At this time, it’s unclear if this was done intentionally or if it was a simple oversight on AMD’s part. It also remains to be seen if third-party utilities will be able to overclock the graphics card in a more unofficial workaround.
Analysis: Why is the lack of overclocking important for the RX 6400?
The problem with the Navi 24 GPU used for the graphics card is that it is significantly underperforming. TechPowerUp recorded performance margins of up to 17% at 1080p and 24% at 1440p compared to the Polaris graphics card.
Its general specifications are also quite low. It only has a 64-bit memory interface, four lanes of connectivity (up to) PCIe 4.0, and due to limited media encoding capabilities, there’s no 4K H encoding support. .264/H.265 and AV1 decoding. ReLive, an AMD feature, isn’t even available for the card.
These power and speed boosts offered by overclocking can make a huge difference in the games that can be run on a PC or in the quality of how they run. The fact that a graphics card as weak as the RX 6400 cannot be overclocked will certainly be a huge disappointment for many gamers on a budget.
