The Celeron 900 is Single Core a 2.2 GHz processor, built on 45 nm technology, and has 1 MB of L2 Cache. It  has 800 MHz of Front side bus.

The Celeron 900 support the 64 bit architecture. The 64 bit architecture allows the processor to access larger amounts of memory. Of course the software needs to take advantage of the 64 bit architecture.

The Celeron 900 is based upon Penryn-3M core, and was launched in the first quarter of 2009 to offer low cost processor for mobile computing. It does not offer hyperthreading. The Celeron 900 processors have TDP rating of 35 Watts.

The intel Celeron 900 fits in PGA478 socket, so, all motherboards having PGA478 socket should be able to support intel Celeron 900.

Th absence of the support for virtualization technology is another drawback of the Celeron 900. The  virtualization technology allows multiple operating systems to run simultaneously on an x86 computer – If this is implemented at hardware level – it is also known as  hardware virtualization. The hardware virtualization usually works great with two core processors.

Intel Celeron 900 Architecture

The diagram above, taken directly from the intel site explains the architecture of the Celeron 900 processor. The CPU is connected to the MCH or the memory controller hub. It is traditionally called the front side bus. The Front side Bus or the Memory Controller hub communicates to the memory.  You will also notice that this is different from the way the i3  and i5 processors communicate with  the memory. The i3 and i5 processors have memory controllers inbuilt, which results in faster memory transfer. This is another reason, you may like to prefer i3 and i5 processors over the celeron processors.

The memory controller hub or the North Bridge connects to another chip called I/O Controller hub ( traditionally called south bridge). The south bridge communicates with USB, Hard disk, optionally with PCI Express and all other IO.

In essence Intel Celeron 900 is a traditional processor good enough for a decent surfing experience , word processing and emailing – nothing more, nothing less.
