AMD stated earlier this year that the Radeon RX 6400 is not intended for retail and would only be accessible to large OEMs when it unveiled its low-end Radeon RX 6400/6500-series graphics cards. But someone has to create these boards, and the EEC database now includes a special ASRock Radeon RX 6400 graphics card. The adapter’s main benefit is that it uses just roughly 53 watts of power, making it compatible with almost all PCs.
ASRock has produced the RX6400 CLI 4G graphics card, which stands for the Radeon RX 6400 Challenger ITX, according to a file in the Eurasian Economic Commission (EEC) customs database (as noticed by VideoCardz).
It’s not surprising that a partner is working on something comparable, given that some of AMD’s official slides show short, low-profile Radeon RX 6400 graphics cards — but we’d generally expect partners to adopt AMD’s standard design with minor tweaks to save money.
The Radeon RX 6500 XT and Radeon RX 6400 are AMD’s desktop discrete Radeon RX 6500 XT and Radeon RX 6400, respectively. AMD’s Navi 24 GPU was built primarily for notebooks, but it has also been brought to the desktop discrete market in the form of the Radeon RX 6500 XT and Radeon RX 6400.
Companies frequently keep entry-level notebook GPUs under the radar, which is why products like Nvidia’s GP108 and the GeForce GT 1010 seldom make it into reviewers’ hands. However, significant shortages of graphics cards and increasing pricing forced AMD to reevaluate its entry-level graphics chip and marketing strategy.
For what it’s worth, the Radeon RX 6500 XT isn’t a particularly fantastic gaming option for 2022: it performs similarly to the RX 5500 XT 4GB card it’s supposed to replace, and it lags much behind the 8GB variant. The Radeon RX 6500 XT’s FP32 compute throughput is extremely similar to the RX 5500 XT’s. The former can deliver up to 5.77 TFLOPs, while the latter can deliver up to 5.2 TFLOPs.
We should expect the Radeon RX 6400 to be slower than the RX 6500 XT because it is a scaled-down version of the RX 6500 XT in terms of GPU cores and clock speeds. This GPU can only provide 3.57 FP32 TFLOPS thanks to its 768 stream processors clocked at up to 2321 MHz. Of course, this is a significant improvement over the GeForce GT 1010 (0.75 TFLOPS), but it still falls short of the GeForce GTX 1060 3GB from 2016. It’s unlikely to be on our list of the top graphics cards unless it’s available at a discount at retail (say, around $100).
The Challenger branding on ASRock’s RX6400 CLI 4G board could indicate that it’s intended at the channel market, but it’s certainly not proof of anything. Keep in mind that anyone may add almost anything to the EEC customs database, thus the entry does not guarantee that ASRock is planning to import its Radeon RX 6400 Challenger ITX into Russia or Kazakhstan.
Probably, the product is only intended for China’s bottomless market, and the standalone RX 6400 cards will not be available in the US, though anything is possible in the present GPU market.
