    This sounds like an Intel PR piece

    "Legit Bottom Line: Intel was able to launch the Prescott processor with major core architecture changes without having a negative impact on performance. Intel now has a core that can be ramped up to 4GHz and beyond with ease!"

    • Intel didn't release the P4EE with the Prescott core.

      That's it.

      Think carefully about this. NORMALLY, Intel will take advantage of the die space saved with the shrink by putting in more cache. Not only didn't Intel do this with the Prescott core, they DID do this with the Northwood core and released it at 3.4GHz with 2Mb L3 cache!!


      Anyone familiar with normal Intel releases can see this as a sign of disaster.

    • Anything can sound like a line of BS when you take it out of context, which is what you did. Done like a true fanboy. Try to at least be a little objective. Not everything AMD does is perfect, nor is everything Intel does evil.

      "The first thing that should be understood with the Prescott is that the Netburst's main branch prediction/recovery pipeline has been lengthened from 20 stages in the Northwood to 31 stages in Prescott. If you've been an enthusiast or in the IT industry for some time,then you know that this has been done before and at an initial performance loss. Intel went from 10 stages in the Pentium III to 20 stages in the original Pentium IV's and the result was a performance decrease. As you will soon see, some applications do take a performance hit due to the change, but the increase in stages will allow Intel to ramp up to higher clock speeds thanks to the new design."

      Right now the Prescott is a tad slower than the Northwood at equal clock speeds, runs hotter, and draws more power, but thats not the whole story. Intel has told us that the Prescott will get better as Intel comes out with higher clock speeds. The sweet spot for the Prescott is rumored to be around 3.8-4.0GHz, which are speeds that are not too far away."

      "One thing you might have noticed in this review is that I didn't touch on temperatures or overclocking of the Prescott. I will be putting out individual reviews covering both of those issues and both are important areas to cover. The Prescott sample we have overclocks very well, which could be different from the retail versions. Just to give you a heads up we are seeing 4GHz+ with little effort on our Engineering Sample."

    • "Intel now has a core that can be ramped up to 4GHz and beyond with ease!"

      Intel's own press release contradicts this conclusion. Or did legit not read the part about 3.4GHz chips coming in March. If it ramps so easily, why the delay (again)?
