I was poking around some in their stock firmware, the CPU seems to be: IPQ5332
Because I also searched for words like broadcom, mediatek, mtk, intel nothing came up. But qcom came:
This line suggests it's indeed qualcomm
Wifi possibly this: qcom,cnss-qcn9224 ve qcom,qcn9224_legacy_irq → QCN9224 chip
qcom,cnss-qcn6432 ve qcom,qcn6432-wifi

If you want dual-band wifi7, wait for the Asus BE59 which might be filogic 850:
(https://www.asus.com/networking-iot-servers/wifi-routers/all-series/prt-be59/)
That seems quite old. Even newly added TP-Link BE450 is using Filogic 880. With much higher IPC. And probably cheaper.
840/850/870 is brand new. The dual-band wifi7 router you linked to in the OP is for the budget market. BE59 will also be a budget router.
Broadcom and qualcom are doing their best to snuff out mediatek for the wifi7 generation.
