It makes sense for AMD to release this SKU only for OEMs due to leftover silicon. At this point releasing a non-igpu Zen 3 SKU makes little sense since Zen 4 is already on the market. But who knows it might hit the DIY market as well ?
One important thing to note is that the CPU is at A0 stepping, meaning that the chip is probably an ES/engineering sample, and there may be some changes before final production.
Therefore, the unreleased processor is faster than the Ryzen 7 5700GE, the 35W more energy-efficient version of the Ryzen 7 5700GE
