Intel Celeron P4500 processor review
The first and foremost thing you need to know about the Intel Celeron M P4500 processor is that it is a dual core processor. So set aside your mental attitude with Celeron as the low performance processor, because the Celeron 4500 is not – not even at the the relatively low clock speed of 1.86 GHz.
The Celeron P4500 belongs to the Arrandale series of processor, and if you have not heard about Arrandale, you would like to know that Arrandale architecture is used in the core i3 and core i5 intel processors. The biggest advantage of the Arrandale architecture is the integration of the Integrated memory controller. This speeds up the processor to memory transfer and this is true for the dual core intel Celeron P4500. You will now realize that the Celeron 4500 is a decent processor – possibly better than even the similarly clocked core 2 processors.
The Arrandale architecture also simplifies the motherboard design by way of eliminating the traditional North Bridge. The processor connects to the chipset directly using DMI Bus at 2500 MHz.
The Celeron P4500 does support hardware virtualization which speeds up the switching between operating systems on the go.
Now comes the drawbacks of the Celeron P4500. The Celeron P4500 does not support TurboBoost – which means that they suffer from the same drawback that the core i3 processors suffer. You will also like to note that te AES instructions and hyperthreading are disabled in the Celeron P4500 processor. While the AES function is also disabled in Core i3 processors, the hyperthreading is supported in core i3 ( and of course in i5 as well), processors. What this will mean that when you have 4 or more processes running simultaneously you will find sluggish performance of the Celeron P4500 as compared to the core i3 processor.
The Celeron P4500 does contain the Intel HD graphics. Both the Intel HD graphics as well as the integrated memory controller are based upon the 45 nm technology, while the core processor itself is based upon the 32 nm technology.
The clock frequency of the graphics processor is 500MHz and is able to overclock to 766MHz due to Turbo Boost.
The Celeron P4500 has level 3 cache memory of 2MB as compared to 3MB in the core i3 processors ( for example core i3-350M).
In overall the Celeron P4500 processor is expected to give decent performance. It definitely is inferior to core i3 processor due to absence of hyperthreading, lower L3 cache ( 2 MB in Celerom P4500 as compared to 3 MB in core i3). It performance level also suffer as compared to the core i5 processors due to the absence of the turbo boost. Additionally P4500 has smaller core frequency of 1.86 GHz.
Next time you hear about Celeron processor in a notebook do not look at it with disregard – instead try to find if it belongs to Arrandale series – and it it does it may be worth a look. The Celeron P4600 is the bigger brother of Celeron P4500 with core frequency of 2 GHz.
Benchmark result for Intel Celeron P4500
Some benchmark results are available for the Intel Celeron P4500 which show super Pi 2M taking 56 seconds. The SiSoft Sandra Dhrystone score has been reported to be 15781.
Some of the notebooks available with the Intel Celeron P4500 processor include HP ProBook WH333UT Notebook, HP Compaq 4320T, HP 4320t XA661AA Notebook PC and some of the Thinkpad L series notebooks.
