AMD Phenom X4 9350e and 9950 BE Debut

0 thumbs up


AMD is launching a three-pronged attack on the desktop CPU space today, with the introduction of three new quad-core Phenom X4 processors.  One of the processors, the new Phenom X4 9950 Black Edition, is AMD's latest flagship desktop CPU.  The other two, however, are somewhat surprisingly "green", low-power quad-cores dubbed the Phenom X4 9350e and Phenom X4 9150e.

With its Black Edition branding, it should be obvious to the power user among you that the Phenom X4 9950 BE is targeted squarely at enthusiasts and overclockers.  But the audience for the Phenom X4 9350e and Phenom X4 9150e processors is a little harder to quantify.   We'll explain what we mean by this a little later.  For now, let's take a look at these new processors' features and specifications to see what each brings to the party...

AMD Phenom X4 9950 Black Edition and 9350e Side-By-Side

Strictly from a technical standpoint, the new flagship Phenom X4 9950 and more power-friendly Phenom X4 9350e and Phenom X4 9150e processors are essentially identical.  They are all based on the same core and have very similar feature sets.  They only differ in their rated clock speeds and associated power ratings.

The Phenom X5 9950 Black Edition, due to its relatively high clock speed (for a Phenom) has a max TDP of 140 watts - the highest of any AMD Phenom CPU.  To reach its 2.6GHz clock speed, the chip requires 1.05 - 1.3 Volts.  The 2.0GHz and 1.8GHz Phenom X4 9350e and Phenom X4 9150e processors, however, are on the opposite end of the spectrum.  These two processors are selectively binned and require a maximum of only 1.125v, which results in a much lower 65 watt TDP.  We should also point out that at 65W, the Phenom X4 9350e and Phenom X4 9150e processors are technically the most power friendly desktop quad core processors available.

Wow, that 9950 is power hungry.  Eek.  They gotta get that down.  Not bad performance, but it's still the same architecture so it's gonna lag behind Intel in many things.

I don't really like re-releases of a same core just with "higher clocks" -- if its the same architecture why not just release it with the rest of the series?

Yeah but at least there getting more up to speed. I hate to say it but even as an AMD enthusiast who's thinking about building a new system I don't know. The power is no issue I'm looking at either the HYPER 885 or 1200 watt unit for power so thats no issue at all. However Intel is supposed to release a totally new CPU in the next 6 months. With the last 2 years of results in processor output and the performance variables I might have to just go intel and DDR3.

rapid, perhaps youd be interested in uying my 1250 watt psu?

I have faith in AMD -- look what just happened between ATI and nVidia! I believe DAMIT is just starting to get their feet under them from the merger way back and beginning to make headway....its only a matter of time

I say this as no fanboi of either AMD or Intel -- just as a guy hoping for good competition

 Hey guys, I have been tweaking some Phenoms and I have found some interesting stuff. Amd phenom is performing better on higher resolutions given the same video card. Would you guys mind testing this for me ? It would really be helpful.  In particular the 9950 even though the 9850 would still be good if that is all you have access to.

 I am bumping this. I am suprised no one is as curious as me.
