Memory's Speed Trick
What is HBM?
Inside your phone or laptop right now, there's a tiny chip doing a trillion calculations per second. But here's the problem: it's so fast that it spends most of its time just waiting for information to arrive. It's like having a championship speed-reader who can devour a whole book in seconds, but someone keeps handing them one page at a time from across the room.
The chip is the processor — the brain that does the math. The information it needs lives in memory chips nearby. Regular computer memory sits a few centimeters away from the processor, which doesn't sound like much. But at computer speeds, that distance is an eternity. The processor asks for data, then twiddls its metaphorical thumbs waiting for it to travel back.
