Looking for a fast arm chip with parralell display controller

I wrote a little software rasterizer that runs on the esp32, which is pretty fast actually. But I have one problem, I can't write to the display over spi fast enough.

So I am looking for a chip(preferably arm) that has an integrated paralell display controller and atleast 240mhz, multicore if possible.

Now above should be achievable, but I need it to support external ram(like the esp32 also is able to do) and be under $3 for one chip.

Anyone know something like that?(I don't need wifi and bluetooth)
