The photo of AMD Barton

Let’s see what the marking means — AXDA1833DKT4D. Athlon XP (AXD), A – desktop, 1833 MHz (how much is it in QuantiSpeed?), D — OPGA, K – 1.65V core voltage, Ò — +90°C temeprature limit, 4 – 512Kb L2 cache, D – 333MHz FSB.

So, it’s none other than AMD Barton with 512Kb L2 cache and 333MHz FSB. The crystal is slightly larger than Thoroughbred 84 sq.mm due to doubled cache. According to WCPUID V3.1, the chip is Model 10 stepping 0.

Taiwanese overlockers have even sped up this chip a bit. 2323MHz clock (185 x 12.5) was achieved using usual air cooling, that speaks for the good o/c potential. A bit confusing is that Barton supports 333MHz FSB instead of recently announced 400MHz. However, this is just an engineering sample, and we might see Bartons with various FSB in the future.
