When the "Brisbane" core made its first appearance in February of 2007, we maintained an apples-to-apples setup, comparing various thermal, power and performance data between the AMD Athlon 64 X2 5000+ 90nm "Windsor" and the AMD Athlon 64 X2 5000+ 65nm "Brisbane".  In this review, we are going to stick to that approach, focusing on a three-way comparison between the BE-2350 and a Athlon 64 X2 4000+ Brisbane core, which is virtually identical except the 4000+ carries a 65w power rating vs the BE-2350's 45w spec.  Lastly, we threw in an Athlon 64 X2 3800+ Windsor core which runs 100MHz slower and carries a 65w power rating as well.

Power & Thermal Characteristics - IDLE

Starting out with thermal and power testings, we recorded the idle wattage of our test system with Cool'n'Quiet enabled.  All measurement were recorded at 30 minute intervals using a Kill-A-Watt meter at the outlet.  In all testing, a stock cooler was used along with Arctic Silver 5 thermal grease.

With Cool'n'Quiet enabled, each processor dropped down to an x5 multiplier, running each CPU at 1000MHz.  As expected, all three processors returned similar results, which is expected.  All three test platforms hovered in the 67-68 watt range while idle, yielding no surprises.

While monitoring the system wattage at the outlet, we also had a copy of ASUS Probe II running in the background to monitor the CPU temperature.

As with the wattage, all three processors ran at nearly the same range, each with 1°C of each other.  The AMD Athlon X2 BE-2350 was the coolest of the three chips, idling at 15°C.
