The T-bred is nothing but an Athlon XP that has undergone a die-shrink to .13 micron. At worst, all that will be needed to support it is a BIOS update.

It hasn't been die shrinked to 0.13 micron yet, until next year comes along for the real 2 ghz stuff according to news from AMD. AMD is still fine tuning the 0.18 micron lithography. If they shriunk the die, the core voltage is going much lower to about 1.2 volts. The rule of thumb of core voltage relationship with submicron rule is about 0.9 of core voltage divided by 10 for submicron line width. But the mask today(same size) can be shrinking line width by phase shift(which is not exact) of light source and 0.15-0.16 micron could be what their Germany plant is doing. The isolation region has a wider line width by default which improves sustaining core voltage.

The Athlon XP has some design changes in the circuits, and it runs higher data transfer rate than the T'bird Athlon. Next year the Oeptron(hammer) 64 bit cpu will be impressive.

In comparison, P4 core votage is 1.5 volts(due to phase shift light source to 0.11(0.13 norm) micron and isolation line width increased to 0.17 micron by default), but their gate oxide is so thin that 1.25 volts became the limit to prevent punch thru on the I/O transistors.
