Originally spotted by @momomo_us over at Twitter, the listed ASRock Challenger Arc A380 is a custom ITX design with a dual slot single fan cooler and a slight overclock to 2250MHz. The TDP is listed at 75W although it still needs a single 8-pin PCIe power connector, suggesting it could draw a bit more power.
The A380 is based on ACM-G11 GPU with 8 Xe-cores and comes with 6GB of 15.5Gbps GDDR6 memory on a 96-bit memory interface and should compete with Radeon RX 6500 and GTX 1650.
The price of $139.99 is actually interesting and even with price cuts, it is cheaper than the RX 6400 by $10, and on the Nvidia side, the cheapest GTX 1650 is around $180.
According to Newegg.com, the cards should be available on August 22nd and are limited to two per customer.
