AMD Athlon II X3 455 Processor Review
The AMD’s Athlon II X3 455 is a triple core runs at 3.3GHz. The Athlon II X3 455 bumps up the frequency of the AMD Athlon II X3 450 by 100 MHz. You will be delighted to know that AMD did NOT increase the price – the 455 costs $87 ( at the time of writing) – same as that of the 450.
If you wish to compare Apple to Apple – the Athlon ii 455 competes head on with Intel Pentium G6950 – a two core processor – at a clock frequency of 2.8 GHz. Interestingly the Pentium G6950 is priced EXACTLY the same as the AMD Athlon II X3 455 – $87 – at least at the time of writing ( Intel Price source http://ark.intel.com/Product.aspx?id=43230).
Now you get one additional core for the same price. And you get 3.3 GHz in place of the 2.8 GHz. Of course, the Pentium G6950 does come with the 3 MB smart cache. It does not takes to be a rocket scientist to conclude that AMD’s Athlon II X3 450 wins over the Pentium G6950. And this has been proven in the benchmark and scores ( Soucer : http://www.anandtech.com/show/3937/amds-fall-refresh-new-phenom-ii-and-athlon-ii-cpus-balance-price-and-performance)
Anandtech concluded –
AMD Athlon II X3 450 has the clock and core advantage. AMD wins across the board virtually regardless of application. The Athlon II X3 450 gives you more bang for your buck than the Pentium G6950.
The comparison between the Athlon II X3 455 and the Pentium G6950 in only going to widen the gap as far as the performance is concerned.
The Athlon ii 455 is based upon four core die and one of the four cores ( likes a faulty one) core is disabled, so you get 3 cores. There is no L3 cache and you get 512KB L2 for each of the three cores.
Other than the frquency bump of 100 MHz, the Athlon ii X3 455 is essentially same as that of the Athlon ii X3 450. Its integrated memory controller can support DDR2 as well as the DDR3.
Built with 45nm lithography Athon ii 455 gets 938-pin organic micro-PGA . This processor fits in AM3 socket. The communication with the chipset is using 16 bit hyper transport bus at 2000MHz.
The TDP rating of 95 Watts is slightly at higher side, however, not unexpected for a 3.3 GHz beast. The 455 can support a max temperature of 75 deg C.
The support for the virtualization technology will help you in case you are using multiple operating systems.
