Many thanks for the clarification.

That's a bit odd making a secret of the chip used in adapters already in the market.
Anyway, is it possible at least for you to tell if it is superior to the 1.5GHz Tri-Core that RE500X/RE505X series brings?

The only purpose of these questions is to figure out which adapter suits my needs better and compare the price differences with performance differences.

Thanks.

Nice one STN!
Thanks.

1. RE500X/RE505X
BCM6750 - Broadcom Tri-Core 1.5 GHz

2x2 802.11ax Wi-Fi 6 Tri-Core ARM SoC
The BCM6750 is a 2x2 802.11ax Wi-Fi 6 system-on-a-chip (SoC) communications processor that enables low-power, small size, multi-gigabit access points, routers, repeaters and service provider gateways for residential applications.
The SoC features a tri-core 1.5 GHz ARM Cortex CPU with a single 802.11ax two spatial stream (2×2) WLAN radio and five integrated 802.3-compliant Gigabit PHYs with multiport Ethernet switching.
