Intel Celeron M 900 vs Intel Celeron M 743 vs Intel Celeron M 722

Intel Celeron M 900

The Intel Celeron 900 is a mobile single core processor for cheap laptops. It is based on the Penryn core (as the Core 2 Duo Dual Core processors) but many features and one core are deactivated. The missing power saving features, like Speedstep, lead to a lower battery runtime (compared to Core 2 Duo powered laptops). Furthermore, features like Virtualization and Trusted Execution are deactivated.

The performance of the single core processor is located in the entry level segment. Due to the missing 2nd core, the performance may suffer when using many applications at once. Otherwise (in synthetic benchmarks), the Celeron M 900 is on par with a 1.3 GHz Athlon II Neo K325. The similar clocked AMD V-Series V120 should be slower due to the smaller Cache and different architecture. On contrast it usually features the faster chipset graphics card by ATI leading to a better overall performance.

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 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.
