"To compare the overclocking potential, thermal characteristics, and power consumption of our .09 micron - Winchester core based Athlon 64 3500+, to a .13 micron - Newcastle core based Athlon 43 3500+, we had to take some precautions and avoid a few pitfalls to ensure the comparisons would be legitimate. First off, we tested each processor in the exact same test bed; only the CPU itself was swapped between tests. The room where the testing was conducted is climate controlled, and remained at a constant 70oF (21oC) throughout. We used the exact same heatsink and fan combo, and the same thermal compound on each CPU. And the fan mounted to the heatsink was connected directly to the system's PSU, to prevent it from thottling at lower temperatures. The tests were conducted with all components mounted in a mid-tower case, but with one side-panel removed. The MSI K8N Neo2 Platinum motherboard we used for testing was updated to the latest BIOS (v1.4), all voltages and bus speeds were set manually, and Cool 'n Quiet was disabled."
