AMD has been moving up the performance charts very quickly over the past couple years. With the Intel Northwood released at the beginning of the year, AMD answered with the XP 2000+. They've released the 2100+ since then, but the 2000+ is still a very speedy chip.
The XP 2000+ still rides the Palomino bus. What this means is achitecturally, the CPU is unchanged from the XP 1800+ we've looked at earlier. As most enthusiasts know, XPs are fast, and they run cooler than the previous generation Athlons, but we're getting to the point that heat is becoming an issue again. Dissipating in the range of 70W of heat, you'll still need a quality heatsink and fan combination to cool the processor.
We're only going to cover a few points today, and provide plenty of numbers to see how it stacks up against it's older brother, the 1800+. Anything else not covered in this review, will likely have been addressed here.
