Intel’s next-generation architecture for low-power chips, code-named “Bay Trail” is expected to hit the streets by the end of the year. Chips based on the platform are designed for tablets, notebooks, desktops, and other low-power computers, and they’ll replace today’s Intel Atom chips.
But Bay Trail processors aren’t just the future of Intel’s Atom family. We’ll also see Bay-Trail chips sold as Celeron and Pentium processors. And they’ll all use less than 10 watts, offering moderate performance and long battery life (assuming you’ve got a decent battery).
We already knew that some next-generation Celeron and Pentium chips would have the same “Silvermont” cores as Intel Atom Bay Trail processors. But now a leaked product list is providing more details about Intel’s planned chip lineup.
Here’s the breakdown:
Intel Bay Trail-I (Atom, likely for tablets, notebooks)
- Atom E3810 – 1.46 GHz single core CPU w/400 MHz GPU and 5W TDP
- Atom E3821 – 1.33 GHz dual-core CPU w/533 MHz GPU and 6W TDP
- Atom E3822 – 1.46 GHz dual-core CPU w/667 MHz GPU and 7W TDP
- Atom E3823 – 1.75 GHz dual-core CPU w/792 MHz GPU and 8W TDP
- Atom E3840 – 1.91 GHz quad-core CPU w/792 MHz GPU and 10W TDP
Intel Bay Trail-M (Celeron, Pentium for notebooks, convertibles)
- Celeron N2805 – 1.46 GHz dual-core CPU w/667 MHz GPU and 4.5W TDP
- Celeron N2810 – 2 GHz dual-core CPU w/756 MHz GPU and 7.5W TDP
- Celeron N2910 – 1.6 GHz quad-core CPU w/756 MHz GPU and 7.5W TDP
- Pentium N3510 – 2 GHz quad-core CPU w/750 MHz GPU and 7.5W TDP
Intel Bay Trail-D (Desktops)
- Celeron J1750 – 2.41 GHz dual-core CPU w/792 MHz GPU and 10W TDP
- Celeron J1850 – 2 GHz quad-core CPU w/792 MHz GPU and 10W TDP
- Pentium J2850 – 2.41 GHz quad-core CPU w/792 MHz GPU and 10W TDP
Update: AnandTech also spotted a listing for a Bay Trail-T mobile chip last month:
- Atom Z3770 – 2.4 GHz quad-core CPU w/2W SDP (scenario power design)
Unfortunately there’s still no word on the graphics technology or the actual TDP of that Bay Trail-T chip, so it’s tough to say how it’ll compare to chips that don’t use Intel’s SDP standard.
Even the slowest, lowest-power Silvermont chips are expected to offer about twice the performance of today’s Intel Atom processors, mostly while using the same amount of power or less.
Intel is dropping support for hyperthreading, but since most of the new chips will have multiple processor cores, they’ll still be able to handle multi-threaded applications. Silvermont chips also support out-of-order execution, so they’ll be more efficient at many single-threaded tasks as well.
Graphics performance should also be much better in Bay Trail chips than in the Clover Trail and Pine Trail chips they replace, since Intel is basically using a slimmed down version of the same HD 4000 graphics technology used in its 3rd-generation Intel Core “Ivy Bridge” chips.
