Overclocking B3, a Little Better

Despite the new 50 series CPUs being a new spin of silicon, the only changes AMD made (that we are aware of at least) were to fix the TLB erratum. We were told not to expect any significant increases in clock frequency out of B3, it was simply a functional change. However, with Phenom having been in production for a little while now it's possible that we could get a little more out of our B3 chips than the first Phenom processors we tested late last year.

Using stock cooling on air we wanted to see how things had changed in four months. Armed with our unlocked Phenom X4 9850, we wanted to see what was possible.

We went straight for 2.8GHz at stock voltage, which surprisingly enough POSTed and got us into Windows without any problems. The system wasn't stable enough to complete most of our benchmarks however, we needed to boost the core voltage a bit:

Note that this is better than any of our previous attempts with Phenom. While we could hit 3.0GHz in the past, it was never stable enough to complete all of our benchmarks. While we only had a few hours left over to test the overclocking stability of the 9850 it does look like it may be the first Phenom capable of easily breaking the 2.6GHz barrier.

We aimed for 3.0GHz and while we could get into Windows and run some benchmarks, we couldn't get it 100% stable. In our opinion it's highly unlikely we'll see AMD release a 3.0GHz Phenom on 65nm this year. It may be possible on 45nm but it's still too early to tell if that'll be this year or not.

    I'm pretty much with you, but just to comment on this part:

    "As for price the q6600 is dropping all over the place... Frys had it for 180 yesterday, Microcenter has it for 200."

    It's a common misnomer to see a sale price on something and then get it locked into your head that that price you saw one time is the price you should expect to pay for something from then on. For example if the company that rhymes with hell is advertising a PC with monitor for $299, even if it's THREE DAYS ONLY in the fine print, or like after rebate, people tend to get it stuck in their head that "a new computer" can be had for a mere $300, when a wiser person would know something that cheap would be like 3-year old tech/speed, likely with dead pixels and a 6-bit analog LCD panel, Windows Basic, stuff like that.

    Companies sometimes have a sale on one thing hoping you'll buy items with it, which allows them to make money. Just wanted to throw that out there.

    How old are you? What's with all this "ownage" crap you are spewing? Do you really tie in your self worth to the cpu you use (feel free to substitute car, house, salary)? Most of us mature individuals who have actually reached adulthood just want the best performance for our dollar, not ownage just to inflate our e-penis.

    Nice article.

    it's "funny" that anand forgot that the e6750 is $180 (not $266) and that the 3ghz oem e8400 (sans cooler) is in-stock and available for $200. the e8400 would certainly push a couple of phenoms lower on the chart.

    and it's also "funny" that anand's comparing projected phenom prices (since they aren't available yet) with real street prices. wait until you can get street prices before claiming a better price/performance ration.

    apparently you didn't read the article. The amd chip is not as good as intel currently, but they aren't crap.

    And if you read the article you would have seen that they still recommended and intel cpu for a new system, so it definately wasn't written with payola in mind from amd.

    We read it, cmon you didnt see any slant towards AMD? Come on, be honest :)

    And it sounded like they were about to cry when they recommended Intel (plus the long in the tooth comments geez, I mean really, Intels old crap sucks and should die but AMDs latest and greatest ALMOST beats Intels crap wow what logic, LOL). Hey I wish AMD were top dog again. I loved the Athlon XP's & 64's. But facts are facts....

    Well look at it this way. Enthusiasts do not drive the market. System builders and servers do. AMD is able to bring competitive prices to the OEM channels and that will also translate to the server markets for the Phenom Opteron lineup.

    AMD is still largely competitive with Intel at the server level with the Phenom where TLB, the now strong point of the Phenom, is implemented better.

    To keep your servers sponsored with a healthy company, IT departments will purchase desktop parts when refreshing hardware. It would be nice for AMD to be able to boast the crown but their company is still profitable, ie in business, by offering parts that sell well.

    Also, its not wise to accuse Anand to being bribed. He's been saying this for a long time and he's enthusiastic that AMD is finally making good on their goals. Fanboi squat somewhere else.

    How is this NOT a fluff piece? A 'new' cpu (Thats only new because the first time around it had a bug) thats 4+ months late to the party.

    Is being beaten by processor that was launch over a YEAR ago.

    In gaming the new processor has even been beaten by a X2 6400+!!!.

    Thats CRAP. How old is that cpu?

    and yet we get conclusions that this is more like the "Amd we're used to seing.. a competitive AMD"? Competitive excatly how? I'll grant you this will push intel to release there 45nm cpu's... But its not like intel is sweeting.

    Futhermore, How can you come out and say the Q6600 is long in the tooth, when its better then the new stuff amd has on the market?
    Long in the tooth because 12+ months after being released its faster then a brand new amd chip? long in the tooth because its easy to find one for 250, and on sale for less? Or just long in the tooth because It just beats the AMD right now, and doesn't whoop them by 20%+?

    I'm standing by my claim this article is fluff/ BS . its written in a postive spin for amd.. When the AMD processor has clearly been beaten again/still.

    I love how fanboys like to conveniently "forget" about the few years that AMD was dominating Intel in pretty much every benchmark when it was the Pentium 4 against the Athlon64.
  • VashHT - Thursday, March 27, 2008 - link

    I don't get what you're saying, are you implying that phenom is competitive because A64 dominated the P4? Funny how you can call someone a fanboy when you're bringing up 2 processors that don't matter in the current market.
  • Goty - Thursday, March 27, 2008 - link

    You kind of have to read the previous post wherein the author implies that AMD has never been competitive, which it has been numerous times. My example was merely the latest and had no bearing on the current generation of products.
