AMD’s chiplet strategy in laptops: balancing innovation and power efficiency. AMD says that chiplet design for mainstream mobile APUs is challenging due to power constraints. The chiplet approach has been instrumental in the success of the Ryzen CPU series. In the domain of laptops, AMD is still evaluating how to approach this idea. During a […]
It’s insane to me that AMD is currently leading the pack in power efficiency (compared to Intel) and yet they consider the chiplet approach too power inefficient for mobile.
I guess all of that efficiency lead is coming from process node alone?
They have great efficiency at 100% load. But their idle power usage would kill any battery.
Thats because AMD just glued together dies on their desktop CPUs to make MCM CPUs, and called them chiplets.
Eg. The thing that Intel and IBM had already done years before.
Apple’s MCM CPUs are power efficient because the dies are right next to each other, but those CPUs cost many times more than either Intel’s or AMDs CPUs.
Intel is trying to leapfrog Apple and AMD by making tiled CPUs, but the packaging method is way more complex and expensive than either of its competitors.
AMD has had a node advantage on Intel for years now. Meteor Lake would be the first generation that they are on relatively equal grounds.
AMD has done extremely well with power consumption under load, low and high, but their idle power consumption is significantly worse.
