    true, it consums 24W less so tdp should be 100w instead 125W that is abaut 20% less

    How about this: these chips feature IMC (memory controllers) that apart from adding to the CPU's overall power load, also fuel the memory modules?

    AMD chipsets (both by AMD and NVIDIA) consume less power compared to their Intel counterparts (chipsets by NVIDIA and Intel), so much so that the same desktop chipsets by AMD make it to laptops. So the difference between a Phenom and Intel Quad in terms of CPU consumption is shadowed by the fact that the lower power consumption of Intel CPUs is marred by higher consumption of the MCH chips (northbridge).
     
    Kei and Viscarious say thanks.

    yes it is true, so u must always lok for total power consumption of system under load

    So 125W you wouldnt put in your pc, but the older p4 architecture hit that did it not?

    Lower power is always better for my utility bills. I hope these clock well. I may wait on these instead of a 9850BE :D`

    Does anyone know when these CPU's are going to get released? And how much will they cost?
    I am planning on buying a new PC at the end of august and I would love to go back to AMD, if these CPU's are decent offcourse.

    I may have to wait and get one of these instead of the Phenom i was going to get.

    You're out of luck. Try January, I think :shadedshu

    I think you are wrong. The G34 is not a Bulldozer. The Bulldozer is a new architecture from AMD. It is 8-16 core and 8-16 threads. It has quad G3MX memory control , it's a fusion cpu with GPU+ CPU side by side on the same die.It also have SSE5 instruction set and a new 170 instruction set.This will be a fast single thread.Sandtiger compete win the server and enterprise market.Bulldozer wiill be in desktop.This bulldozer to be 3X the performance of the shanghai.

    not sure where it hit, but i had a P4 weld itself to the heatsink, and no im not exageration here

    Lol, they are not.

    The AMD 45nm Deneb will finally be able to compete with the Intel Q-series. But don't forget that Intel will release their next-gen CPU's only a month or two after AMD Deneb release.

    They are not back, they are seriously behind...

    It is completely irrelevant where the power goes. Fact is it is a single small chip from where you have to move heat away. According to your logic putting a GPU and CPU on a single die and have some 300W monster is good "because it also has the GPU". The only relevant thing there is that it is near impossible to move away 300W from a single small die, no matter what tasks it fulfills.
    I'd rather have two chips.

    But then energy spent on the machine remains the same, right? As also the machine's total heat generated? It's not like the stock coolers AMD supplies with these 125W chips can't keep them reasonably cool.

    This does look promising; however i have a question:

    If say you wanted to sacrifice this energy saving could you not just pump some voltage through it to get to a higher clock - providing cooling is ok?
