A great progress point! Budget phones now have 1GB RAM, a million times more.
The GPUs of budget phones have 10's of GFLOPS... to make a comparison with the ZX81, what's the fastest Z80 routine you could write to multiply 32-bit floating point numbers? Or perhaps, how fast is the routine in the ZX81 ROM BASIC (by Steve Vickers)?
Thw ZX81 had a 4MHz Z80, but in "slow" mode, about 3/4 of that was occupied in rendering the screen, making it effectively 1MHz. In "fast" mode, the screen went black...
