The current leader is Intel It just announced two new P and U-series mobile processors. We spoke to Daniel Rogers, Senior Director, Mobile Product Marketing and Intel, to better understand the new processors.
P and U series
The P series is a bit new to us. We’ve had a thin and light 28W design point for a few years, but the reality on the market is that most systems are traditionally built at 15W. So this generation, we did something a little different, we actually introduced two production lines, the P series at 28 watts, and the U series at 15 watts. We really did this to get more performance. The P Series is similar to our H Series and is derived from that core architecture, but we’ve optimized that for lower power for thinner and lighter designs, so we can deliver enthusiast-grade performance or an innovative variant that’s advanced to that thin and light form factor.
The P series starts with 14 cores. So it’s 14 cores and a higher strength. Our U series is more designed. So it’s 10 cores, less performance and eight efficient cores and less power. Other than that, on a technological level, they are very similar. IO is similar. The hacks are similar.
The most important audience for the P series are the creators on the go, the people who edit the video, but they still need a thin and light form factor. So maybe they’re not looking for 16″ separate graphicsMaybe they’re looking for a 14-inch system, maybe a system with great battery life with a great camera, but they still need some horsepower to get their video editing tasks and photo editing workflows done. So this is probably the most direct use of the piece or the perfect client for the P series.
How does P series and U series thermal engineering help your energy efficiency?
There are several ways to think about efficiency. So one definition of efficiency is, sort of, performance per watt, ISO power performance or power performance. And Alder Lake is really incredible in that regard. It’s really what we mean by hybrid performance. Our goal is to show that we built this hybrid architecture explicitly to deliver more efficient power performance. It also evolves and delivers amazing peak performance as well. But our sustainable performance is also significantly better, generation after generation. So maybe this is just one efficiency vector.
The other, of course, is battery life, not an active state, but more of a low-power state. So, video playback or, sort of, like light web browsing and that stuff. We have some things going on in this area. So one of the things that we’ve done is a lot of work in software to try and fine tune these instances. It’s still a work in progress and we’re really just getting started with the hybrid this year. We have a big roadmap for how we plan to use this on future generations.
