AMD Phenom II X2 550 

Released November, 2009
  • 3.1 GHz
  • Dual core
  • Unlocked
5 Out of 10

In fact, it's usefully faster than the two Athlon chips clocking up 33 frames per second compared to 35 and 37 frames per second, respectively.

4GHz on air cooling is clearly quicker than its closest competition and allows the 550 pulls further ahead.

You can now buy PC processors with as many as six cores and support for up to 12 software threads in parallel.

What People Are Saying Give it to me straight

Socket Type

Make no mistake, running at its maximum 4.2GHz overclock, the Intel chip absolutely annihilates the Phenom II X2 550 BE in games.
by Tech Radar (Sep, 2010)
It would also be unwise to assume that the 550's two hidden cores are likely to work when unlocked.
by Tech Radar (Sep, 2010)
We're also disappointed to find that our 550 sample fails to function when you enable the two hidden cores.
by Tech Radar (Sep, 2010)

Applications

Its advantage in gaming gets even bigger when you take overclocking into account.
by Tech Radar (Sep, 2010)
It's definitely a more effective gaming chip than other low-cost AMD processors.
by Tech Radar (Sep, 2010)
That said, if you're willing to spend a more on an Intel chip, you'll get way more gaming performance.
by Tech Radar (Sep, 2010)

Multicore

With that in mind, why would anyone want the dual-core AMD Phenom II X2 550 Black Edition?
by Tech Radar (Sep, 2010)
If building a gaming rig on a very tight budget is your bag, the dual-core AMD Phenom II X2 550 Black Edition just about adds up.
by Tech Radar (Sep, 2010)

Gaming

But it's still a lot slower in games than a decent Intel processor.
by Tech Radar (Sep, 2010)

Overclocking

It also overclocks pretty well.
