It’s a dual core MCU that runs at around 240MHz.

One of the main limitation tends to be to be around pushing pixels to the screen - most displays are serial (SPI) based which tops out at 80Mhz.

The other limitation is a lack of hardware video decoding. Some of the latest ESP32 chips are RISCV based and have SIMD instructions which can improve decode performance.

But if you pick an easy to decode codec (MJPEG) is popular. The you can get decent performance with the size of displays available.

I understood the parent coment as wanting to build a WIFI card, i. e. the ESP32 connects to the WIFI and transfers the data to a connected computer over PCIe or so. The ESP32 would have to do no decoding of the payload, only transfer the packets to the PC.
Ah, makes more sense.
