Intel Celeron M 722 vs Intel Celeron M 743 vs Intel Celeron M 723

Intel Celeron M 722

The Intel Celeron M ULV 722 is a single core laptop / embedded CPU that is similar to the Celeron M 723 but features a lower TDP of 5.5 Watt (versus 10 Watt). The performance is slightly beyond the cheap Atom N450 / N280 series. As other Celerons, the M722 does not support Speedstep and Virtualization technology.

Intel Celeron M 743

The Intel Celeron M ULV 743 is an ultra low voltage single core processor for small sub-notebooks / laptops. It performs slightly above the Atom single core lineup and is intended to power cheap CULV laptops.

The Celeron M 743 is based on the Penryn core but support only a stripped down feature set. For example Speedstep is not supported leading to a higher idle power consumption than other laptops with Core 2 / Pentium processors in this TDP range. Furthermore, 64 Bit support and Virtualization in hardware are not supported.

Intel Celeron M 723

The Intel Celeron M ULV 723 is an ultra low voltage processor based on the Penryn architecture. It features only one core and is intended for the use in very small laptops and netbooks. Many features of the Penryn core are deactivated, like Virtualization VT-x, Trusted Execution support and most importantly power saving functions like Speedstep. This leads to a higher power consumption without load.

The performance of the Celeron 723 is only comparable to Intel Atom N470 on average. In some benchmarks, however, the Celeron can be significantly faster (e.g. SuperPi). All in all, the performance is only suited for very low demanding tasks.
