Anandtech did a virtual preview of the Phenoms using AMD server processors and this is what they found. Looks like AMD will be able to compete with Intels Quads but not beat them. As their final word says below, it's gonna be really tough for AMD because producing these phenoms will cost them more but to stay competitive they will have to reduce the costs, making this price war even worse for them. Which of course really sucks, I hope they can get out of this without being bought out or something.

You see, we've known for a while that Barcelona was going to do well for AMD on the server side. AMD is far more competitive there than in the desktop market, mostly thanks to its Direct Connect architecture, something Intel won't be able to duplicate until the end of 2008 with Nehalem. Barcelona will improve clock-for-clock performance over Opteron and is a drop in replacement for Socket-1207 servers with nothing more than a BIOS update; the Enterprise world couldn't be happier.
Things are different on the desktop; AMD hasn't been competitive since the launch of Core 2 in the Summer of 2006 and we're very worried that even after Phenom's late-year launch, the market still won't be competitive. While that's great for consumers today, the concern is that a non-competive AMD will bring about a more complacent Intel, which we do not want. We want the hungry Intel that we've enjoyed for the past year, we want ridiculous performance and aggressive pricing, and we won't get that without an AMD that can fight.
But AMD won't tell us anything about how Phenom will perform, other than that it will be competitive with Conroe/Kentsfield. So the goal here today is to get an idea of exactly how much faster Barcelona (the same core that'll be in Phenom X4) will be compared to the Athlon 64 X2.
We can't draw too many sweeping conclusions based on the data here today, but here's what we do know:
- Gaming performance is much improved with Barcelona over K8, this is most likely a result of the improvements to the SSE engine and the wider front end of the core.
- Encoding performance is improved (again SSE128 rearing its head), but 3dsmax saw an unexpectedly large performance improvement.
- With a 10 - 15% increase in performance on average, Phenom should be more competitive than K8 was on the desktop (as expected).
Here's where things get complicated; we knew Phenom/Barcelona would be faster clock for clock, it was only a matter of how big of an improvement we'd get. If we are to believe that 15% is the best we'll get on average, taking into account that Penryn is around 5% faster than Conroe, the updated architecture from AMD alone isn't enough to really compete with Intel. In other words, price matters.
We saw how competitive AMD became after the first round of price cuts this year, but after the second set Intel went back to dominating. The trouble for AMD this time around is that Phenom is a much larger chip than the outgoing Athlon 64 X2, whereas Intel's Penryn family will actually be smaller than Conroe. AMD is already losing a considerable amount of money each quarter, so fabbing a larger chip at the same price as current CPUs will only make the situation worse. However, Intel can afford to continue to keep its processors as aggressively priced, especially moving to 45nm.
To put it plainly: Phenom/Barcelona make this price war more difficult on AMD, while Penryn makes it easier on Intel. What's the end game? Is there a solution? We're not sure, all we know today is a starting point for Phenom expectations.
That's what she said...
