AI GPU demand driving memory bandwidth revolution

Bullish+1.31%

AI Summary

The author argues that memory bandwidth, rather than raw capacity, is becoming the critical value driver for AI computing, signaling a bullish outlook for memory semiconductor suppliers.

$NVDA $MU $DRAM Memory has a new unit of value: bandwidth (TB/s). Rubin: 288GB at 22 TB/s. Blackwell Ultra: 288GB at 8 TB/s. Same capacity. Nearly 3x the speed. Massively more value. You can’t get 22 TB/s by adding more DDR. Bandwidth comes from a 2,048 bit interface sitting millimeters from the GPU on CoWoS. Only three suppliers can build it. AI buyers pay for memory by how fast it feeds compute, not only by how many bits it holds. This is how memory revolution starts.
