CPU Chart, Processors Hierarchy

What about this other CPU that’s not on the list? How do I know if it’s a good deal or not?

This will happen. In fact, it’s guaranteed to happen because availability and prices change quickly. So how do you know if that CPU you’ve got your eye on is a good buy in its price range?

Here is a resource to help you judge if a CPU is a good buy or not: the gaming CPU hierarchy chart, which groups CPUs with similar overall gaming performance levels into tiers. The top tier contains the highest-performing gaming CPUs available and gaming performance decreases as you go down the tiers from there.

However, a word of caution: this hierarchy is based on the average performance each CPU achieved in our charts test suite using only four game titles: Crysis, Unreal Tournament 3, World in Conflict, and Supreme Commander. While we feel this represents an acceptable cross-section of typical gaming scenarios, a specific game title will likely perform differently. Some games, for example, will be severely graphics subsystem-limited, while others may react positively to more CPU cores, larger amounts of CPU cache, or even a specific architecture. We also did not have access to every CPU on the market, so some of the CPU performance estimates are based on the numbers similar architectures deliver. Indeed, this hierarchy chart is useful as a general guideline, but certainly not as a gospel one-size-fits-all perfect CPU comparison resource.

You can use this hierarchy to compare the pricing between two processors, to see which one is a better deal, and also to determine if an upgrade is worthwhile. I don’t recommend upgrading your CPU unless the potential replacement is at least three tiers higher. Otherwise, the upgrade is somewhat parallel and you may not notice a worthwhile difference in game performance.

Summary

There you have it folks: the best gaming CPUs for the money this month. Now all that’s left to do is to find and purchase them.

Also remember that the stores don’t follow this list. Things will change over the course of the month and you’ll probably have to adapt your buying strategy to deal with fluctuating prices. Good luck!
