Yes, this should be fact checked. It is called the RG405 because of a 4in IPS screen. The RG505 has the 5in OLED, hence the 5 in the beginning. That screen has 2x the psp resolution because it is from the psp vita. The title of this is a complete lie. A vague, and poorly written article on the actual device.
I believe there are some inaccuracies in this article when it comes to screen specs. Everything Anbernic has put out so far suggest 640x480 led panel. The 2x PSP resolution OLED screen mentioned in the article can be found on the older RG505 model. Hope this clears up confusion for people looking to purchase.
Anbernic has presented the RG405M, a 4.95-inch gaming handheld with an OLED display. Powered by the Unisoc Tiger T618 and LPDDR4X RAM, the Anbernic RG405M runs Android 12 and has a 5,000 mAh battery that should last up to 8 hours of gameplay between charges.
