3.2 GHz
Tri core

0 Out of 10 CPUBoss Score		It's truly stunning value for money when you compare it to Intel's pricey dual-core processors. by Tech Radar (Jan, 2011) If you get unlucky and the fourth core doesn't fly, performance is still decent in the context of such an affordable processor. by Tech Radar (Jan, 2011)

	8.0 read review	We should point out that there are absolutely no guarantees when it comes to unlocking cores in AMD processors.

Socket Type

With the fourth core unlocked and the chip clocked up to 3.6GHz, this processor is ludicrously quick for a sub-£60 CPU.

by Tech Radar (Jan, 2011)

Multicore

But perhaps its most intriguing feature is a hidden fourth core.

by Tech Radar (Jan, 2011)

Price

But then it does cost less than one third the price.

by Tech Radar (Jan, 2011)

Performance

The harsh truth about the AMD Athlon II X3 450 is that it only exists because AMD is currently struggling to compete with Intel for raw processor performance.

by Tech Radar (Jan, 2011)

Type of CPU

In the meantime, AMD is forced to scrounge for scraps at the budget end of the market.
