In exactly the same place.
AMD sold all the CPU's they could get manufactured during this period and were supply constrained.
Shortly after Conroe came out, AMD was picked up by Dell and despite now being far less attractive an option due to Conroe, couldn't adequately supply their regular retail channels, due to giving Dell first bite of the cherry.
How on Earth could they have done any better when the K8 was the undisputed King?
People need to stop telling themselves this comforting lie that AMD would have been great, if not for nasty Intel doing the dirty on them.
I actually enjoyed the Athlon / Athlon XP era a lot more than the Athlon 64 / X2 era.
Prices were awesome during AXP, and lower models could OC to insane levels, then Athlon 64, especially when they went to X2, they went completely flagship on pricing. I actually built a few Intel Pentium Ds purely for value, lol. Cheapest X2 was $300 for the 3800 x2, while 805 Ds I could score for about $120, and OC them between 3.8 and 4.1Ghz. X2s would run better after also OCing, but at 3.8+ the 805 was faster than a stock 3800 X2. IIRC, the Zalman 9500 was my go-to for those, because it was pretty cheap and tamed the PDs down into the 60s @ load.
And both Intel and AMD were only too happy to throw $1000 CPUs at us with little to no real value or common sense.
