    Intel announces 45nm Penryn family

    Penryn is Intel's first 45nm CPU family, with some fancy technology like 'High-k' and 'Metal Gate' featured in it. Penryn family processors have been fabbed and Intel say they've got them working, but production hasn't been ramped up yet; they will hit the market in the second half of this year, which gives us time to explain what these fancy words mean. Shall we...?

    Usually you need a new mobo because the new cpu's use a lower voltage that your older mobo cant do....but i think with new mobos doing speedstep and powernow and all that power-saving jazz....we should be ok.

    if the voltages are too high, you'll just have to overclock it, to absorb the extra volts, like

    in all honestly, X2 is just fine for almost everything today.. even games for that matter..

    Makes perfect sense to just wait it out for the 45nm chips..
    Me want Ultrabook

    Taken from DailyTech's new post...

    ""Motherboard developers will have to make some minor changes to support [Penryn]. We can't guarantee that a person could just plug the chip into every motherboard on the market today." However, Smith also claimed the Penryn boot test that grabbed so many headlines last week occurred on unmodified hardware that included a notebook, several desktop motherboards and several server motherboards."

    That suggests a yes, but they can't guarentee it in every case without actually testing it.

    Knowing the reasons Conroe's wouldn't work in earlier boards (or BadAxe at least) I'd imagine that it won't be a problem this time around.

    I think there should be an article saying exactly which processors we will all be buying in a few months time: AMD Barcelona/Stars or Intel Penryn?

    As has been said above there can't be any guarantees about individual boards as yet, but Intel have pretty good form as far as backwards compatibility is concerned.

    Coppermines worked on Deschutes/Katmai boards, Prescotts worked on Northwood/Willamette boards. Hell, Tualatins worked on Katmai boards with some simple modifications and that's a two generation jump when you think about it.

    The times there have been big problems in this area have been the occasions when the CPU package design changed, and as it doesn't seem as though they're making any changes to the physical or electrical design of LGA775 for Penryn, it should then be down to motherboard manufacturers updating BIOSes with the appropriate microcode updates and VRM programming, as and where necessary.

    Even if the manufacturers don't support it directly, if it can be done, you can guarantee that some of the enthusiasts will find out the way.
    BH6, BX6 2.0, BE6, BE6-II 2.0, ST6-RAID, BE6-II 2.0 (again), BD7-RAID, BD7II-RAID, IC7-G, IC7 Max3, AB9 QuadGT, IX38 QuadGT. IX58... Oh, b*ll*cks. RIP Abit

    it will be interesting what performance jump this will bring and if it allows any increase in clock speed etc (not always guarenteed - look at amd's 65nm part)

    From what I've seen 3.46-3.73GHz and a reduced TDP were the target.

    AMD told us from the off that there would be no performance gain, it was purely to lower power consumption and die size. they will be using it to prepare themselves for Barcelona while still being able to produce processors right now.

    Intel on the other hand are suggesting tasty improvements. i MAY HAVE to jump on this bandwagon... the current Core2 is good enough but cooler and faster (and potentially cheaper) is going to be hard to resist
