5's a cool number?Why 5x?
Very, very likely, IMHO. The Clawhammers clearly aren't going to deliver, at least not in the initial stages. AMD's going to need something to really challenge the seemingly problematic Prescotts. People are going to want to hang on to their Socket A configs for a while longer, also. Not to mention how wonderfully the new JIXHB's are overclocking. I'd say that a 2.4ghz default Barton should be very easy for AMD to fab now, or at least in the near future.P.S. By the way, off topic, I don't see Athlon XP 3400 or 3600 happening? What do you guys think?
What about this: ... although Prescott may not translate into a new official core name, Intel Tejas due out Q4 2004 most probably will.Gautam said:

The channel length will probably be significantly shorter with the last T-Breds. This is what is going to allow them to run so much faster, but also make higher levels of overclocking significantly detrimental to the processor.Originally posted by hitechjb1
Its transistors have lower threshold characteristics due to process variation which produces transistors with shorter channel length. Shorter channel means lower transistor threshold, runs faster, draws larger leakage current and higher active current (hence higher active power). According to AMD spec, the 1.5V 1700+ has higher rated current than the 1.6V 1700+ (about 7% more).
Threshold voltage of a transistor is the gate voltage above which the transistor will conduct current orders of magnitude higher from source to drain compared to that below the threshold. Chips with lower threshold transistors can perform equally well with a lower supply voltage (Vcore) as those with higher threshold, because the transistors can conduct at a lower gate voltage.
This is normal for a given silicon process (say 0.13u) to have such variation that some transistors in certain chip die have shorter channel length (less than 0.13u) or some have longer channel length. Those that have shorter channel length have faster intrinsic speed and can run as fast when smaller Vcore is applied (pros). On the other hand (cons), due to the lower threshold voltage which draws higher leakage current and generates more heat at the same higher Vcore, these chips can run as fast at a low Vcore as the higher Vcore rate chips, but they will max out at a lower Vcore compared to the higher Vcore rated siblings.
The 1700+ has a run-away current at a lower Vcore compared to the 2100+. Run-away current refers to the leakage current and the heat generated positively feeding each other resulting instability.
