Thermal Comparison

One of the commonly overlooked but most important purchasing decisions for many users is heat dissipation and power consumption of CPUs. Whether you're building a server farm and are looking to stay within a certain power envelope or if you're building a quiet home theater PC, knowing what processors in your performance range run the coolest is quite useful.

As a new addition to our CPU reviews we're providing tables of heat dissipation of every major desktop CPU since the Athlon 500 & Pentium III 500. At the same time, we're also providing a graph comparing the heat dissipation of all of the latest CPUs (all Athlon XPs vs. Pentium 4s). To access this data just make your selection according to what CPU (core) you're interested in:

AMD Athlon | AMD Athlon (Thunderbird) | AMD Athlon XP (Palomino) | AMD Athlon XP (Thoroughbred)

Intel Pentium III | Intel Pentium 4

We hope you find this feature useful, please provide us with any feedback you may have on how to improve and expand our reviews in the future.

    This article says that the Athlon XP 2600+
    won't have a 333 FSb . But I just purchased an
    Athlon XP 2600+ and on the box it says 333 FSB.
    Now can someone please clarify? and will it Run
    on my DFI AD 73 Pro(VIA 266A chipset)motherboard?
