Many of you out there just getting into the overclocking scene may have heard about "blue" or "green" colored AMD die's. Now let me clarify what a die is. On an AMD chip, the spot in the center of the ceramic where the actual wafer of silicone is contained is what they are referring too. In the light, it will either shine green or blue. Sometimes this is indistinguishable but more often than not, you'll be able to tell. The reason why this is often thought of as important is because the newer Dresden fabrication plant uses the blue coloring to distinguish it's fab from others. Now, some people say this also refers to the CPU having copper interconnects or not, well... let me set the record straight.
According to AMD's latest tech brief, they've decided to hold off on producing copper interconnects on their .18 micron process due to the "faults with present technology." In real person talk this simply means that they don't think present copper technology amounts to much and so, aren't going to waste the money on upgrading their fab plants just yet. Although copper is a better electrical conductor and looks good on paper, at this present time when it is new to the PC industry, I tend to agree with AMD. Maybe this will be something to look forward to when everyone converts to .13 micron... but until then, don't expect to find copper anywhere.
Sorry to disappoint many of you who were hoping the rumors were true, but this writer has the skinny from AMD and is gonna run with it, got that? For now, copper interconnects are fictional as far as amd durons are concerned and remains the subject of many heated debates as to whether or not the thunderbird contains them either. For right now at least, neither of them do.
Despite all of this, "Blue" colored cores seem to overclock better than green ones for some reason or another. Whether it be coincidence or merely the fact that blue is made in a NEW plant with newer machines, still remains to be seen. But this fact is still out there and whenever you see "blue" mentioned describing a core, you can pretty much bet it'll be a winner where overclocking is concerned.
Is this true or not? So where do we stand now as far as buying retail vs OEM if we are overclocking? Wouldn't it just make more sense to buy OEM and buy a good HSF?
