Throughout the past few CPU articles we've mentioned that now is an absolutely wonderful time to be building a new system thanks to incredibly competitive CPU prices. The AMD/Intel price war has really paid off in making the marketplace more competitive. The fact that you can buy a very fast quad-core processor for less than $300 is just incredible.

At the same time, it's very easy to get caught up in recommending the higher end parts simply because they are priced so low now. AMD's entire Socket-AM2 product lineup can be had for under $300, but we've primarily focused on the $150 - $300 range, when both AMD and Intel have some very powerful CPUs available at or below $100.

For many, these processors are great for primary systems built on a budget, but for others they make a solid foundation for a good second or third system, file server, or machine for a friend/relative. Price/performance means everything, but you don't always have the luxury of choosing a $160 processor over an $80 one, despite the incredible value of the former. At the same time, power consumption and noise matter tremendously, especially if you're building a Home Theater PC or file server, where CPU performance isn't necessarily the most important thing but building a quiet, power efficient system is.

Then there's the question of motherboards; it's finally possible to build a fast system that actually uses integrated graphics if you're not going to be playing any 3D games. Relying on integrated graphics will further reduce the power consumption and noise level of your system. There's no point in testing these CPUs with $200 - $300 motherboards, so we decided to focus on more affordable platforms, including testing with integrated graphics. This is the full experience: we're pairing $80 CPUs with $80 motherboards and seeing where they end up.

The question is this: if you're building a fast but affordable system, but you want it to be 1) low power and 2) potentially use integrated graphics, what do you do? We're about to tell you.

    why not the cool & quiet idle power numbers?
    seeing they're running at full speeds at idle is besides the point of an "idle" measurement in this age with powersavings...

    tnx though on the bios update request from asus... I want to tweak my timings too.

    C&Q and EIST were both enabled for the idle and load power numbers. Actually all the benchmarks were run with those settings enabled.

    Take care,

    I realize the benchmarks are run at 1024x768 to make the tests CPU-limited, does that mean all, or at least most, of the extra horsepower needed for resolutions above that comes from the GPU? If so, does that mean I could run games at 1280x1024 well with a high-end card and one of the AMD CPUs from this round-up? Or would that be a bad match-up? If that would work it's an appealing upgrade path alternative to jumping platforms.

    why not color code those performance graphs so that we can easily see which processors are competing at the same price
