Price Comparison

Unfortunately the Phenom X4 9x50 stock seems to be currently a little low across the channel, hopefully this will change shortly. If you shop around though, you can still find a good deal but be aware that most retailers (and Google) are still listing them as “Phenom 9850” not “Phenom X4 9850” for example.

At the time of writing, there is plenty of stock in all the above online stores and there’s a linear price increase across the range. Compared to the B2 Phenoms at £117.79 and £132.94 for a 9500 and 9600 Black Edition respectively, the 9750 drops right in next to the 9600 BE. Of course, it’s worth remembering that even though it has a slightly faster (100MHz) core clock, it also has a locked multiplier. Both undercut the Intel Core 2 Quad Q6600 G0 by just a few pounds although it’s not as if the Q6600 isn’t still the default choice for many given its considerably greater headroom.

The Phenom X4 9850 Black Edition might certainly become the weapon of choice for AMD enthusiasts though – at under £160 it’s half the price of the Q6700 and it’s the fastest commercially available Phenom to date and a good CPU has been shown to do 3GHz.
