    I said it before and ill say it again, Im willing to benchmark my rig at any clock people request me to. 4.8 Ghz is the highest i can get stable, so what I was originally trying to do was only compare my findings to what is found online, which is generally not 2600ks @ 4.8 Ghz, but this would be ideal, and I am very intrested in finding someone with a 2600k/6990 to do some real comparisons with.

    Clocks should always be kept in mind when looking at any set of benchmark comparisons, nothing to hide. The majority of my benchmarks have "fair" comparisons, the rest I could simply not find high clocked intels to compare with. Comparing to a lower clocked CPU can still give you at least some idea of how each chip performs. If you look through my review I have a lot of data points, not just comparisons with low clocked intel chips like some people make out to be.

    So in your honest opinion which performs better per core an AMD FX 8150 at 4.0 GHZ @ $249.99 or an AMD Thuban @ 4.0Ghz @ $149.99. To me the problem seems to be AMD bet on more applications taking advantage of multicore support which that is where FX is better than Thuban. But currently multicore support is still a rarity which has made thuban still a better choice and for less money I might add. I think FX 8150 was a step backwards if they want to compete with Intel and the their prior flagship they should drop the price to at or below the price of thuban.

    dunno 4.8ghz on SB is not exactly an extreme overclock, I have been running well over a year at 4.7-4.8 and I have an average chip. I would of looked harder for exact clock comparisons between BD and SB if I wanted a more legitimate comparisons

    Ugh dude...really? 4.8ghz is high even for SB. You shouldn't even go past 5ghz unless you are on water.

    yes really, your 4.4 is pretty much a baby overclock. 4.8 your in the moderate range, very doable on air even with a volt hungry chip like mine. 5.0 is doable on air if you have a low voltage chip. point is the OP should of looked harder for clock for clock comparisons.

    Uhm 4.8 isnt that high. I can run 5.0ghz with respectable temps, but i dont like that much voltage going through it.

    yeah 4.8 is much more common than you think dude

    I hit 4.8 pretty easily for the lawls back when I had one. As these guys are saying it's not hard. Past 4.4 is the realm of actual overclocking on these chips, aka when you actually have to start increasing voltage.

    Can't wait to see what Ivy is capable of when I get my hands on it

    In my opinion the following are equivalent (averaged performance - not in every test)

    4.8 ghz FX 8150 +Patches = 4.5 Ghz Phenom II X6
    4.5 ghz FX 8150 +Patches = 4.3 Ghz Phenom II X6
    4.1 Ghz FX 8150 + Patches = 4 Ghz Phenom II X6

    Clock per clock a Phenom II X6 will out perform an FX 8150.

    Ivy bridge isnt looking pretty either, looks like (From OCC):

    4.9 Ghz 2600k = 4.7 Ghz 3770k

    where:

    4.9 ghz 3770k = 103 C
    4.9 Ghz 2600k = 65 C

    It is when we are talking about air. Think about most users out there. Not just a small percentage.

    It really helps to see the bigger picture.

    agents on the same cooler as me megahalems rev b AIR cooler. only difference is his cpu and cooler are lapped for lower temps and he has a lower voltage chip. apples to apples 4.8ghz 2600k and 8150 should be easy as pie if you look around for benches. apples to oranges just clouds the picture in favor of the 8150.
    @OP IB is looking a bit toasty but the architecture is sound. It is actually a bit faster clock for clock than SB. a new revision may iron out the temps. so it is actual faster than previous generation unlike other chips lol

    Nobody said it was hard to overclock a chip. Point is that it's a high end OC when it comes to temps before aircooling isn't enough. It's around that no passing zone.

    So to say it's not a high end OC isn't very accurate imo.

    a 4.6 Ghz oc on air for a 2600k is a standard oc
    a 4.6 Ghz oc on air for a FX 8150 is a standard oc

    a 4.8 Ghz oc on air for a 2600k is a high oc
    a 4.8 Ghz oc on air for a FX 8150 is a high oc

    in best case scenarios, the 2600k generally overclocks higher than the FX 8150, but the delta is around the same.

    I disagree. 4.4 I consider minor, 4.6 average, 4.8 moderate anything higher than 4.9 you are in the high range. 4.8 for BD is very high due to the heat produced so you cant really do an apple to apple comparison 2600k vs 8150 (oc range) as the SB will run much cooler. you cant go 4.6 avg to 4.8 high as you do not list a moderate oc

    Best way imo to compare is to match their power consumption (example 2600k at x.xGhz with 1.xv overclock consuming 120w load vs AMD FX 8150 at x.xGHz with 1.xv consuming 120w load). That would give you the most accurate results of what is better. Another way could be to use the same mid air range cooler on both and push both to max thermal safe under load then see what one is better. I highly doubt the AMD FX chip could touch any modern Intel in PPW overclocked or not.

    I think doing it clock for clock is pointless because we all obviously know Intel will win in most things unless they are very multithreading intensive and AMD FX will always consume more power and run hotter (if cooling is the same on both platforms).

    My two cents.

    Bulldozer also eats up more power at 4.8 than a Sandy Bridge or Ivy Bridge processor.....

    power hungry and inefficant a win win situation

    megahalems cooler, not on water.. yet

    like tommy said, its more moderate, 5.0 imo is a high end oc.

    btw at these clocks, i hit low 70s max in P95. daily usage is usually in 50s(gaming) using two 1200rpm fans in push/pull and i got a slightly above average chip, nothing special.
    so yes air cooling is enough.

    Bulldozer is the most power hungry chip overclocked, but ivy bridge i7s are the hottest chips by far! Hence, why they generally wont even overclock as high as an fx 8150 on air cooler. Temperature (This will limit your oc) is more of an issue than power consumption for overclocked Desktop Rigs, Power consumption is mostly important in the mobile market.

    Ivy Bridge is a much smaller processor using completely new transistor design. Bulldozer on the other hand uses standard transistor design. Intel is still working out bugs in both transistor design and a new fab process. Besides, thermal issues are much easier to deal with than lack of efficiency in the processor design.
