Yeah, that's a savage bastard too. 48MHz, DMA, UART, I2C, SPI, a sleep mode ... 16KB flash and 2KB ram. Certainly enough to run something with a UI, probably enough to implement a basic software defined radio, could probably do some neat tricks when buried inside a USB cable.
I mean, clearly we're at the "splash the cash" end of the Chinese processor market here but at least you get good bang for buck.
Not sure what you mean by "this price point" but CH32V003 is RISC-V and around 10 cents. It is only 6 times more expensive.
