    I'm guessing it's likely to be one of the newer ones, I really have no idea though.
    I'm just asking out of curiosity, I'll be sticking with my choice of parts.
    I was told a few years ago that a 1ghz single core athlon was faster than its intel equivalent, no idea if that was true, tbf I didn't understand how that worked then, just started thinking about it the other day and decided to ask here.

    "1ghz single core athlon was faster than its intel equivalent"
    it was true, but that was too long ago
    now clock for clock i7 is probably the best, then core 2 duo, then phenom

    but keep in mind that it is very general

    This is a very general question, going for the second best in hardware as usual, typical me.
    That 1ghz athlon system did die in an amusing manner (Plugged it into a badly rewired plug, blue flash laptop made loud noise, tried to turn it on again 2 days after it worked fine until I tried to plug it in and all the lights went out XD).

    i think with modern cpus it goes:
    -bloomsfield (best)
    -wolfdale
    -yorkfield
    -conroe
    -kentsfield
    -allendale
    -k10

    im not completely sure about the differences between wolfdale/yorkfield and conroe/kentsfield. k10 (phenom) is at the bottom because it takes a 3ghz phenom x4 9950 to beat a 2.4ghz q6600, i got that from one of the first reliable 9950 reviews i read.

    AFAIK wolfdale, yorkfield,conroe kentsfield and allendale are all part of the core micro-architecture so they won't be different from clock to clock only differences are die shrinks, revisions, added instructions which would make that cpu faster in certain calculations.

    As for the most efficient clock for clock i'd think it would be something IBM came up with a few months ago called Power6

    hmm I find this kinda awkward,
    last I checked 9850 was better than q6600, but that is minor,
    allendale above K10 this I don't think so, just doesn't make sense, since phenom series x3's can handle up to at least e8400. unless your talking high end wolfdale's then that is another can of worms

    Are they high end x3's compared to the e8400 since they have another core on it so it's not nescessarily a fair comparison.

    Best transistor-count : performance has to go to Core 2 Duo E8600. With just a Penryn die, that chip is a monster at gaming.

    AMD's 3ghz dual core are about 30-50 percent slower than a 3ghz 8xxx

    but all the Intel architectures listed don't belong to Intel.. so...
    for me it goes like this-
    1. Table Based Execution Architecture
    2. K-10 "HyperTransport" based Architecture

    My bad but still yea the x2's do get smoked by core 2's and so forth. But still I think sometimes going dual core to dual core is a bad comparison since if we want to be honest AMD has lost every battle since conroe was introduced.

    That's called AMD cheating, much like intel saying AMD might have cheated with its 6ghz OC lol.

    Well not entirely true since thier power efficient opeterons are dominant in the server market.

    well that I can agree with that they aren't doing to bad on the server end.

    Aren't the opterons in the current most powerful PC in the world?
    I'm talking about the IBM roadrunner here so it may be a bit out of date.

    he is right, just checked wiki, roadrunner is top one right now.

    Not much has advanced in the last few months then, heard about that from the guardian's tech podcast ages ago.

    If you want pure performance per watt, then something like the IBM Cell processor is definately up there. Opterons as well, but even though the Cell isn't x86, in terms of pure performance it is very, very powerful.

    No amds?

    Here's my list,
    I7
    Yorkfield
    Kentsfield
    Wolfdale
    Conroe :D
    Phenom
    Athlon X2
    Allendale
    Pentium 4..

    hmmm actually it needs to be reworked slightly,

    see but phenom has an oddity with x3's.
    Also you forgot conroe.

    The 6502. It's old. But was the most efficient CPU at the time.

    I'd say in order of instructions it can do in a clock cycle

    i7
    Yorkfield/Wolfdale
    Kentsfield/Conroe
    Phenom
    Athlon 64
    Pentium 4

    Yorkfield and Wolfdale will be the same because yorkfield is the 2 wolfies stuck together same with kentsfield and conroe. Although a phenom will beat a conroe since there is only two cores.

    What's the most efficient Architecture clock for clock? doing what? float? int? branching?

    That just went completely over my head W1zzard. I was just asking it as a general question, if you want to be specific I'd say for gaming.
