It's surreal isn't it? Is this how you pictured it? With forty-three days left in the year, AMD is finally letting us publish benchmarks of its long awaited Phenom microprocessor. The successor to K8, AMD's most successful micro-architecture to date, and the cornerstone of AMD's desktop microprocessor business for 2008: Phenom is here.

But shouldn't there be fireworks? Where's the catchy title? The Star Wars references were bound to continue right? Why were there no benchmarks before today, why are the next several pages going to be such a surprise?

AMD had been doing such a great job of opening the kimono as its employees liked to say, giving us a great amount of detail on Barcelona, Phenom and even the company's plans for 2008 - 2009. The closer we got to Phenom's official launch however, the quieter AMD got.

We were beginning to worry, and for a while there it seemed like Phenom wouldn't even come out this year. At the last minute, plans solidified, and we received our first Socket-AM2+ motherboard, with our first official Phenom sample. What a beautiful sight it was:

These chips are launching today, with availability promised by the end of the week. Phenom today is going to be all quad-core only, you'll see dual and triple-core parts in 2008 but for now this is what we get.

The architecture remains mostly unchanged from what we've reported on in the past. This is an evolutionary upgrade to K8 and we've already dedicated many pages to explaining exactly what's new. If you need a refresher, we suggest heading back to our older articles on the topic.

The Long Road to Phenom

Ever wonder why we didn't have an early look at Phenom like we did for every Core 2 processor before the embargo lifted? Not only are CPUs scarce, but AMD itself didn't really know what would be launching until the last moment.

At first Phenom was going to launch at either 2.8GHz or 2.6GHz; then we got word that it would be either 2.6GHz or 2.4GHz. A week ago the story was 2.4GHz and lower, then a few days ago we got the final launch frequencies: 2.2GHz and 2.3GHz.

Then there's the pricing; at 2.2GHz the Phenom 9500 will set you back $251, and at 2.3GHz you'd have to part with $283 (that extra 100MHz is pricey but tastes oh so good).

The problem is, and I hate to ruin the surprise here, Phenom isn't faster than Intel's Core 2 Quad clock for clock. In other words, a 2.3GHz Phenom 9600 will set you back at least $283 and it's slower than a 2.4Ghz Core 2 Quad Q6600, which will only cost you $269. And you were wondering why this review wasn't called The Return of the Jedi.

AMD couldn't simply get enough quantities of the Phenom at 2.4GHz to have a sizable launch this year (not to mention a late discovery of a TLB error in the chips), and the company was committed to delivering Phenom before the holiday buying season as these are tough times and simply waiting to introduce its first quad-core desktop parts was just not an option. Rather than paper launch a 2.4GHz part, AMD chose to go with more modest frequencies, promising faster, more competitive chips in Q1 2008. It's not the best PR story in the world, but it's the honest truth.

Two more quad-core Phenoms will come out in Q1: the 9900 and 9700, clocked at 2.6GHz and 2.4GHz respectively. The Phenom 9900 will be priced below $350 while the 9700 will be a sub-$300 part. As you can probably guess, the introduction of those two will push down the pricing of the 9600 and 9500, which will help Phenom be a bit more competitive.

It's worth mentioning that in the 11th hour AMD decided to introduce a multiplier-unlocked version of the Phenom 9600 sometime this year that will be priced at the same $283 mark. Whether or not it's called a Black Edition is yet to be determined.

Intel Responds with...really?

    damn where is the rating system??!! Reply

    If you read the graphs, you will see they are testing total system power draw. Typically they test at the wall with a Kill-A-Watt meter, though this article does not explicitly state that.

    Assuming the other components were the same between systems, this number then shows the difference in Processor + chipset power consumption between the platforms.

    Barcelona is the name of the server processor, ("> ) is one test. Intel power consumption is pretty much screwed by use of the FB-DIMMs.

    The comments on this topic were great. AMD really let us down on this one. I trade Intel stock, but only buy AMD chips and today I am so dissapointed. I hope AMD read these reviews and get their act together. Patience is a virtue, so I am going to wait for another review after better yeilds have been produced. Guess I can tuck my cash back into my wallet.

    mmmm, Maybe AMD was joking with this chip. Could Santa be delivering the real Quad? With this reveiew we better hope so.

    I hope all of you choke on your comments. You're completely judging amd on pre production samples that will all mature and give more accurate benchmarks by the time they hit stores. No it's not a core 2 killer but amd never planned for it to be. They laid out a road map some time back and are following it as best they can with the resources they have. It's the first native quad core, intel can't say that. It's brand new, so it's full potential hasn't been seen and probably fully developed yet. You gobshites are just like the rest of America I have to live with everyday and want it NOW. You sound like a bunch of 2 yr olds screaming mine mine. Reply

    Anand stated that AMD has promised availability by the end of the week, so unless they shipped him below-average samples to test, this is indeed representative of what will hit stores at first. AMD may or may not have planned it as a Core 2 killer, but if Intel outperforms them on speed and power usage at the same prices, who is gonna buy AMD? Being the first native quad-core is an interesting Trivial Pursuit fact, but it won't win many sales unless performance goes up or price goes down. Reply

    All we can do as consumers is make educated choices based on the information we can get.
    Your arguement is "wait and see," which is not a bad position to take, but this is the first TANGIBLE evidence of what AMD can do with its new chips, which most of us have been waiting over a year for. The information we have right now says that the current best AMD quad core chip can't compete in performance with the slowest intel based quad core, which if our information is correct, will cost the same.
    By comparison, you can see the first time Anand got a hand on a test sample of Conroe, the results eventually foreshadowed real world performance:

    I wonder what happened on this test?">

    the same way cpuz showed the phenom as single-channel memory, this sandra test is probably showing the result from 1 of the memory controllers... thus both channels together are undoubtedly pumping out 10000+, which makes a LOT more sense Reply

    So apparently AMD's chips have higher memory bandwidth for integers and FPs. But so what if it ain't faster? Reply

    I've waited for Phenom as a potential upgrade to my current three systems (Socket 754 Semprons, AMD64). Reply
