If you are already buying a Radeon RX 6400 is not interesting for many users (performance, PCIe 4.0 x4, no H.264/H.265 encoding or AV1 decoding), AMD is now known to have deliberately blocked the possibility of overclocking to that GPU, so the company’s most basic model can’t squeeze extra performance to deliver a bit more smoothness for users who can’t afford to buy a more powerful GPU.
Essentially, TechPowerUp claims that AMD has fully locked down the Radeon RX 6400. Although it is stated that the overclocking panel is accessible in AMD Radeon WattMan, at the moment of truth you cannot change any settings.
“There is no overclocking on the Radeon RX 6400 because AMD has completely locked this card in,” the website explains in its review of an MSI-built model.
“Wattman’s OC settings panel shows the ‘custom’ option, but when enabled, there are no sliders or anything else to adjust.”
According to the tests carried out, in all 25 games tested at Full HD resolutionuniquely in four of them it manages to exceed 60 FPSthe average being fair 38.3fps, which is 5.6 FPS less than a Radeon RX 570 released in 2017. For this reason, the overclock would be essential to try to gain a few additional FPS to at least guarantee to exceed 40 FPS in most games. good if, costs 190 euroNot that it’s going to make things any better.
“Averaged across our entire test suite at 1080p resolution, the Radeon RX 6400 really fails to impress. 17% behind the RX 57028% behind its big brother, the RX 6500 XT, and 30% behind the GeForce GTX 1060.
The performance difference compared to the last generation RX 5500 XT is 40%, which is probably why they called this board “RX 6400” and not “RX 6500 non-XT”. Nvidia’s most entry-level GeForce 30 card of the current generation, the GeForce RTX 3050, is almost exactly two (!) faster than the RX 6400, but of course it’s also twice as expensive.”
