Just a bit of copy pasting, but;
RPi 4:
Broadcom BCM2711
Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
2GB, 4GB or 8GB LPDDR4-3200 SDRAM
Broadcom VideoCore VI 500 MH GPU
CPi 3.14:
A-0604
ARM64-bit Dual-core Cortex-A72 @ 1.8GhZ and ARM64-bit Quad-core Cortex-A53 @ 1.4Ghz
4GB LPDDR3
Mali-T864 4 core GPU
A few frequencies are missing re: RAM and GPU, and the information isn’t like for like, but where it counts it is.
I posted something similar in this thread.
But basically, the A-0604 is plenty powerful compared to a rPi4, and arguably the GPU is better too.
