Athlon vs. PIII

[Oli Wade]

Yes it is a Duron. The 'model' is the key; see
http://www.sandpile.org/ia32/cpuid.htm for full CPUID details.

For K7:
---
1 0.25 µm
2 0.18 µm
3 0.18 µm with 64 KB on-die L2 cache
4 0.18 µm with 256 KB on-die L2 cache
---

1 & 2 are the original slot A Athlons. 3 = Duron (Spitfire), 4 = new Athlon
(Thunderbird), both (mostly) socket A.

Remember too that the L2 cache is exclusive.
