Your next laptop’s biggest bottleneck might not be its chip; it could be how well it stays cool. A new white paper from Ventiva, developed alongside analyst firm Moor Insights and Strategy, argues that thermal design is quickly becoming the deciding factor for how fast AI laptops can actually run.
Why memory bandwidth is the real bottleneck
The paper explains that local AI performance is measured in tokens per second, and that number mostly comes down to memory bandwidth. Most laptops today still rely on 128-bit memory buses paired with LPDDR5 memory, which caps bandwidth around 150 GB per second. That is simply not fast enough to run today’s…
