65nm Athlon X2 7850 hits Newegg at $69

AMD has introduced a new dual-core Phenom derivative: the Athlon X2 7850 Black Edition.

This dual-core offering is based on the same 65nm silicon as the quad-core Phenoms. AMD has simply disabled a couple of the cores and left the 2MB L3 cache intact (plus 512KB of L2 cache per core). At 2.8GHz with an unlocked upper multiplier, this CPU has a suggested retail price of just $70—about half the price of the 2.8GHz, triple-core, and 45nm Phenom II X3 720 Black Edition.

Newegg already has the chip in stock for a dollar less than the official MSRP, and with free shipping. That puts the newcomer right up against Intel’s 2.5GHz Pentium E5200, which AMD claims to have lower performance for the money. The Pentium’s power envelope is a good 30W lower, though.

Update: This post originally referred to the Athlon X2 7850 as a 45nm processor. That was incorrect; this chip is in fact based on 65nm silicon.

    For overclocking enthusiasts these just don’t make sense with Intel e5000 series going for the same price. At least they’re a step up from previous A64 x2 CPUs but still not especially compelling. Maybe if you had a much older early AM2 setup and just wanted some more CPU speed it makes a little sense but $70 is like 1/3-1/2 a new budget platform.

    Would anyone even consider this given how cheap and powerful 45nm triple-cores are?

      • Farting Bob

      The PII x3 720 costs twice as much. If your on a budget $70 is alot, and in many basic tasks you wont see the difference. $70 CPU’s can do just as well on the desktop as a OCed i7.

    95W is too much for my mATX box, but still a nice deal for those with larger enclosures.

    Isn’t this the same as the 2.7Ghz 7750 BE with just a .100 increase in speed. I don’t get it. Why not just release a 3.0 ghz version instead of a 2.8. Am I missing something?

      • shank15217

      Yea, this isn’t much news.

        That’s what I thought.

    • thermistor
    • 12 years ago

    Anand showed a 40W difference under load, which is even worse than implied.

    If it was me, I’d get the PDC, overclock to 3 GHz, beat the pants off the X2 in everything, and still draw less power. But that’s just me.

      • KarateBob

      Only 3GHz?

      I have an E5200 in my HTPC running stock voltage at 3.15Ghz 24/7/365 with a semi-passive Scythe Ninja Mini. Clearly the chip could do better with a better MB and more voltage. The system which has two Hauppauge cards and an HD 3650 DDR3 draws just 84W at idle. Clearly a better overall system than any dual core AMD (even if AMD has vastly superior IGPs).

        That’s pretty good. What PSU and how many HDs do you have?

          E5200

    Whoops, double post.

    I’d buy this if it were s939.

      I’d seriously buy it if it were S939. I’m still using an S939 system!

        • A_Pickle
        • 12 years ago

        Lots of people are. I think AMD wouldn’t do badly to give S939’ers a little treat here and there, as most of those people are otherwise probably gonna upgrade to Intel-based systems for the forseeable future, if/when they choose to upgrade.

      The anandtech review shows a 40W difference at load.

      • Lazier_Said
      • 12 years ago

      The Anandtech review showed a 40W advantage to the E5300 at the wall.

      What is this phenomenon that makes AMD’s obsolescent previous generation process only suck on paper and not in the real world?

    • 5150

    Did you know it’s 65nm not 45nm?

    • flip-mode
    • 12 years ago

    Anandtech had a review up a day or two ago. Beats a C2D E5400 in gaming, but loses in everything else.

    As others have said, it is 65nm Phenom “One” derived, at least according to Anandtech.

    I could not bring myself to partake of anything based on the 65nm Phenoms, but the 45nm Phenoms are hotness, so I am looking forward to seeing how the 45nm dual cores do when they get here.

    • toyota
    • 12 years ago

    yeah its 65nm not 45nm.

    • JoshMST
    • 12 years ago

    Yeah, its a 65 nm B3 Phenom.

      • flip-mode
      • 12 years ago

      Heh, long time no see! Coincidentally enough, I just visited your website this morning. Some /serious/ cob webs there.

        Hey Flip… yeah, haven’t updated Penstar in over a year now. Been spending all my time writing for PCPer.com these days. Covered the X4 955 in fact the other day!

    • sjpeters79
    • 12 years ago

    It should be 65nm with a 95w thermal envelop. I think msrp should actually be $79 so it’s actually $10 cheaper than what it should be.

    Um, the 7850 is based on the 65nm Phenoms, not the 45nm Phenom IIs. That needs corrected.

    How they managed to get to 2.8GHz is beyond me…

      • d2brothe
      • 12 years ago

      Two cores only, much lower power draw, less heat…so you can push the limits a little further. Plus they’ve probably refined the chip and process further.

      • Meadows

      Binning must be new to you.

        • Game_boy
        • 12 years ago

        No, I know, but if the parts are basically discontinued in favour of Phenom II, then why did they put the effort in to get 0.2GHz higher than the highest Phenom bin when it was the flagship? Shouldn’t they have put the process engineers on refining 45nm and the chip designers on, say, Bulldozer?

          • mattthemuppet
          • 12 years ago

          this may simply be clearing inventory/ production capacity until PII production has ramped up enough.

    • duncan426
    • 12 years ago

    I believe this is still 65nm.

    • ssidbroadcast

    ACC hacks, anyone?
