Apple just took a big step towards upping its chip-making game, and it took a big swipe at Samsung in the process. According to the Wall Street Journal, Jim Mergard, a well respected and vastly experienced engineer, has left the Korean company for Cupertino.
The move is a big deal for a few reasons. First, it signifies Apple's commitment to designing its own chips. Its A6 chip in the iPhone 5 was the first to use Apple's own custom core. While Apple had been using chips customised for its products, those were built on ARM's architecture — the Cortex-A8 and A9. In simple terms, Apple had been just tweaking things here and there with the blueprints. But with the A6 it built the chip design from the ground up using just ARM's reference designs, not its ready-made cores. That is a very big deal in the world of chip design, and they are largely behind the boost in the A6's performance and battery life.
How does Mergard fit into that? His experience includes work on SoC chips and an AMD chip that was meant to power low-end PCs. That could mean a few things. The Journal cites Patrick Moorhead saying this could be Apple moving to build SoC chips into its Mac computers (the MacBook Air would make the most sense there, probably). Or the hire could be to bolster improvements to the custom core Apple built for the A6 in order to stay ahead.
While you chase down talent wherever you can find it, Apple also probably took at least a little special pleasure in hiring away a talented engineer from Samsung. Especially after Samsung declared that chip design is something it wants to focus on.
For now, you're not going to notice much from one chip engineer exchanging addresses. But down the road, next generation or the one after that, as Apple goes farther down the road of differentiating its chips, this could turn out to be a pretty big deal. [Wall Street Journal via Cult of Mac]
