Power Consumption

Built on the same 45nm process as Penryn, we expect Nehalem to have higher power consumption than Penryn but given Intel's target of a 1% increase in performance for no more than a 1% increase in power consumption per microarchitectural change - the results should be reasonable:

Total System Power Consumption - Idle

Total System Power Consumption - Load

And reasonable they are; for a 20 - 50% increase in performance, total system power consumption only went up by 10%.

    The chances of AMD dying are approximately... zero. The question is whether they stay as an independent company or get bought by someone else. Their IP and patent portfolio alone are worth more than the company's current value, even if they didn't sell a single CPU and didn't have any fabs.

    The top candidate is Samsung, followed by IBM, followed by the UAE. But the real nightmare scenario is this: Microsoft buys AMD, and slowly makes its software incompatible with (or run much slower on) everyone else's CPUs. After that, they have zero incentive to improve the chips, because no one else can compete anyway.

    Since it's been shown that Microsoft can violate antitrust legislation as much as it wants (as long as it pays off a few senators), this is not at all impossible. Be afraid. Be very afraid.

    That would be the beginning of the end for MS.

    MS buys AMD? .... that would be the day I buy a fully loaded Mac Pro.

    Listenting to whom? Somebody as naive and clueless as you, who apparently believes breaking laws in the past should be forgiven and forgotten until there is no competition at all, because the market will magically make things work out perfectly for the customer anyway...?

    If Nehalem comes out and does run circles around current processors, then we're better off, right?

    The only problem is that Intel is holding back on it's CPUs.

    Without competition, Intel will only give us 'just a little taste'.

    Me personally? I want the full strength version at today's prices.

    AMd is still competitive in the price segment of lower end cpu's, and after the PT4 debacle intel doesnt wanna loosen it's grip anytime soon to AMD.

    You've written:

    "Encoding performance here went through the roof with Nehalem: a clock for clock boost of 44%."

    But your graph shows the exact opposite. I'm assuming you just got the numbers on the graph the wrong way around, rather than your analysis mixed up.

    Uh, sometimes bits get flipped when in transfer from Taiwan, yeah, that's it.

    Anyhow, thanks for the notice. Fixed.

    exactly what I expected.

    imc was long overdue for intel...


    can't wait to buy one, but I've been hearing us mere consumers wont be able to until well into 09?
