Irrelevant
"processed and deleted in 0.00417 seconds – less than the blink of an eye"
How long it took is completely irrelevant.
However, for the sake of argument: My phone can happily construct a FullHD full colour scene for a game fast enough to animate it all in real-time. Imagine doing that on a BBC Micro (or four our leftpondian friends, an Apple II).
Technology moves on, things get faster. Stuff that was thought impossible (like 1GBit direct to your home) is now the possible. So how fast that machine processed the images is not relevant. That it did, is.
