    It turns out it ain't that bad from a performance perspective. There isn't a massive drop in performance, despite half the cache size of the X2 3800+ model. Slightly slower in some areas.

    Question is, how much is an extra 256kb of cache worth to you? :)
    (Looking at various local prices, the difference between 3600+ and 3800+ is about $30 to $50)

    Yes it does prvoe.. how little level 2 cache effects AMD64 CPU.. much like the Sempron / A64 issue...

    It also shows how well the the $299 Intel Conroe E6300 performs in its stock configuration...at 1.83GHz... with these chips overclocking to between 3.0 and 4.0..... its makes the market for The AMD AM2 CHips.. look very very sad...

    It would be difficult to recommend an AM2 x2 chip to anybody.. except at the very very lowest end... I guess a $79 VIA motherboard and a $190 3600X2, could find a place in some systems...

    Although $139 gigabyte Conroe ready motherboard (945PL-S3) and a D805 for $152, may be a little slower .. but is infinitely more flexible for upgrading later..

    Actually... Who on earth who buy an AM2 x2 processor...??? The market for the 939 Variants. are for people upgrading..... BUt if you have to buy a new dual core CPU / motherboard and RAM... you would have rocks in your head to buy AMD at the moment...

    Good to know that the X2 3600+ Sempron ;) doesn't suffer too much from the halving of the L2 cache. A 1 - 5% difference is hardly noticeable, and it makes a good alternative to the X2 3800+ for those on a very tight budget.

    I have to agree with Kelvin though, anybody who isn't looking for bargain basement DC would do well to consider C2D instead, at 3GHz+ it would leave any overclocked X2 far behind, and it's not that much more expensive either.

    Interesting how with less cache the X2 3600+ performs quite well compared to the X2 3800+.
    But I have to disagree with Kevin here, I would say you have rocks in your head buy any P4DC atm and to mate a Conroe with a 945 board what a waste.

    Especially since AM3 cores a meant to be compatible with AM2 boards, theres a whole extra 2 years of longevity ( another year for the AM3 to come out and another year for it to be superceded)

    There is no doubt conroe kicks atm but for those of us on a budget and looking at future proofing, a $150 board and a $200 cpu are hard to pass up.

    hmmm, the $30 difference in X2 3600 and the X2 3800 means i can now stretch to a 7600GT :)

    Ahh, Chris Nolan, the AMD 'chainbolt' (take it as a compliment mate ;) ).

    Even if what you say is true, and 65nm X2s can scale to 3.2 - 3.4GHz easily, AMD is merely playing catch up to C2D, instead of being 40% slower overclocked it now becomes 20% slower overclocked - better, but not enough to sway most enthusiasts.

    C2D's are easily attaining such clockspeeds TODAY, and overclocks will only get higher over time. By the time 65nm starts rolling out at the end of the year I'd expect C2Ds to consistently hit above 3.5GHz on air. AMD can tweak and enhance the 65nm K8 but it won't make up much of the 20% clock for clock deficit. If they can claw it back to an average 15% I'd say congrats for a job well done.

    Don't forget by the time 65nm X2s are widely available (Q1 07), Intel will also release the E4300, a 1.8GHz 800MHz FSB C2D without VT and VPro. It will be the cheapest C2D and should command the pricing currently belonging to the PD-805, which suggests it would be around $150 -$160 (according to StaticIce).

    Overclockers.com thinks it will be the budget overclockers chip to get in 07, and I tend to agree:

    AM2 just doesn't seem that attractive at the moment, and I don't see it challenging C2D until K8L is released.

    Any eta on the 65nm chris? id grab one so it can babysit for a few months instead of a 3800 x2.

    AM2 is the best value system to build at the moment. Intel has finally caught up and its great to have some competition for once. :D until k8L offcourse, and the new ati chipsets sound like an OCers dream.

    lets not forget that althon x2's are still very fast, essentially fast enough for anyone that doesnt run benchmarks, i think the 3600/3800 x2s will be a very good option for many systems

    Im sure most gamers for example would benefit more from spending $150-200 extra on a videocard than on a core2duo, until you get to quite an expensive system (probably better off in most peoples pockets :p)

    At the low end, I'd still be inclined to go for AM2 over old Netburst stuff (I built up my parents' machine using an AM2 3500+, was considering a 3600+ X2, but weren't in stock at the time).

    If you've only got a few hundred for board and CPU, a low end X2 and nVidia chipset board is still a pretty potent combo for the money. However, it's hard to argue that when the budget goes up, Conroe looks ever more convincing.

    I do think that AMD needs to get out 65nm production ASAP, and try to take advantage of the fact that the low end Intels are still old P4-based CPUs. Compare a 3600+ to a Pentium D 915, for example, or even compare single core stuff (I mean, AM2 Semprons would EAT the equivalent Celerons, IMO).

    Once Intel release their E4300, if the low end dualcore AMDs aren't competitive on price and performance, AMD will be in for a bit of trouble, I think. I wonder how much the drop to 800FSB will affect the C2D?

    Don't forget this is an enthusiast forum, so 2nd best is normally not 'fast enough' for us hardware junkies. ;)
    Warning: This mentality normally has an adverse effect on your wallet. :p

    An X2 3600+/3800+ would be ideal for the budget buyers for sure, though.

    Considering it 'only' runs at 1.8GHz stock, I'd say not that much. At 2.66GHz, C2D gains on average 2.4% from a 1066MHz FSB to a 1333MHz one. Click

    If you compare the clockspeed to FSB ratio, 1.8GHz/800MHz = 2.25:1. 2.66GHz/1066MHz = 2.5:1, so the clockspeed/FSB ratio is actually better on the E4300 than the higher end Conroes.

    So it'll be ~2% slower overall from the FSB drop from 1066MHz -> 800MHz.

    Ah, OK then.

    I'd like to see how the low end X2s would compare with the E4300. I think that the natural competitor to the E4xxx will be the 3600-3800+ X2, so I'm hoping that AMD is competitive price and performance wise to those.

    Still, the 3600+ seems like a good CPU, but I bet most people will spend the small amount extra for the 3800+, despite the small performance difference.

    Yeah, if I had to choose between the two I'd probably spend a little more for the 3800+ as well.

    I figure at stock speeds the E4300 will be equal to or slightly faster than the X2 3800+, taking into account the current ~10% gap between the 1.86GHz/1066FSB E6300 and the X2 3800+.

    -60MHz and 800MHz FSB should equate to ~5% lower performance compared to an E6300, but at it's proposed pricepoint whose going to complain?

    Ahh, good times ahead for budget DC buyers for sure...

    Once the E4300 is released early next year I think we can expect X2 3800+s to drop to ~$150. :thumbup:

    What sort of penalties or performance hits, if any, will we expect from running a K8L based processor in an AM2 platform? That to me is quite interesting and if the penalties or performance hits are minimal, then going AM2 route now would become more attractive. Especially for those who are on a budget.

    Yeah, I'm intrigued about this also.

    Where would people draw the line though? A 5% difference? 10%? At what point would it make more sense to go AM3 instead of hanging on to an AM2 mobo?

    I recently built a cheap system for myself..

    and went AM2 3500+... in games it is just as fast as a X2 4200+

    Conroe was too $$$..

    wasnt prepared to fork out extra dolero just for a few frames here and there and a poofteenth of a second faster encoding :lol:

    I wish they were bringing this out for s939 :( . The results for it overclocked to 2.6GHz are very tempting indeed.

    Shhh, he's trying to justify his purchase. ;) :D
