No external power supply is required would be a small advantage of the AMD RX 6400

by ·

In recent years, most of the new mainstream graphics cards have relatively high power consumption, not to mention some beasts that require three 8pin power supplies or have been replaced with new 16pin power supply graphics cards. Now the new cards basically start with 8pin, and everyone has seen graphics cards that do not require an external power supply for a long time. Until recently, AMD’s new entry-level game card RX 6400 with RDNA2 architecture, the plug-and-play graphics card that some gamers liked that does not require an external power supply is back.

Videocardz recently discovered an upcoming RX 6400 Challenger ITX graphics card from ASRock, which has no external power supply interface. It should not only be ASRock, the RX 6400 of other companies is also likely to be designed in this way, because the TDP of the RX 6400 is only 53W, and the 75W that the PCI-E slot can provide is more than enough. However, it is a little strange that the radiator of this RX 6400 graphics card of ASRock is very thin, but it uses a dual-slot PCI design, which may make some ITX cases more embarrassing.

It is said that the RX 6400 is modified with the Navi 24 core, with only 12 CUs and 768 stream processors. This specification is very similar to the RX 680M core display on the Ryzen 6000 series mobile CPU that AMD launched earlier this year. Even the core frequency is similar, between 2039-2321MHz, and the IF cache with 16MB, of course, as a standalone display, it is equipped with 4GB GDDR6 memory, but the bit width is only 64-bit, and the bandwidth is only 128Gbps.

According to the performance of the RX 680M core display, AMD RX 6400 should still be able to handle a lot of games under 1080p, and the performance is estimated to be close to the GTX 1650.
