The first specification listed for all computer systems on the market tends to be the processor that is the heart of the computer. Typically it will say the brand, model and speed rating. Clock rates may be posted but this isn't a good indicator of performance anymore as different product models don't necessarily have the same performance at the same clock speed. This can make it very difficult to determine how good a machine is. After all, one processor running at a specific speed may not run as well as a different model from the same manufacturer with a similar clock speed. That is why I have pieced together this list of categories to let you know how functional each processor is.

Before listing the various processor and categories, I wanted to point out that for many people and their typical usage, they don't really need a very fast processor. This has to do with the processors offering much more performance than the current software out there can take advantage of. There are still a few computing tasks that consumers might do that merit a higher end processor but I recommend that buyer's read my How Fast A PC Do I Really Need? article to get a good idea of what they might want to look for.

Outdated Processors

Processors that fall into this category are generally no longer in production by the manufacturers and are typically sold in either extreme budget systems or older refurbished systems. Machines with these processors will typically take longer to run application and possibly might not even run some of software on the market today. It is best to try and avoid systems with these processors unless you want to use a computer for the very basic functions.

Budget Processors

These are processors that may or may not be in production anymore by the manufacturers but are very inexpensive and functional. There are typically two types of processors that will fall into this category: older high-end processors no longer manufactured and new low end budget processors. Discontinued high-end processors typically provide a better bang for your buck functionally. While they may have a slightly lower clock speed, the architecture of the processor tends to allow them to actually perform better at most computing tasks than newer budget processors. These types of processors will often be found in desktop PCs around $400 or so.

  • AMD A4-4000 and Higher
  • AMD A4-5000 and Higher
  • AMD A6-6200 and Higher
  • AMD FX-4100 and Higher
  • Intel Core i3-3210 and Higher
  • Intel Core i3-4130 and Higher
  • Intel Core i5-3330 and Higher
  • Intel Pentium G2010 and Higher
  • Intel Pentium G3220 and Higher

Middle Processors

This is the segment of the market that is probably the best overall value for your computing dollar. While they are not the fastest processors on the market, they still perform very well in all aspects of computing. They may not have the total functional lifespan of the highest end processors, but the price to performance ratio tends to outweigh their longevity. These are typically found in desktops priced between $700 and $1000.

  • AMD A6-5400K and Higher
  • AMD A6-6400K and Higher
  • AMD A8-5600K and Higher
  • AMD A8-6600K and Higher
  • AMD A10-6500 and Higher
  • AMD A10-7700K and Higher
  • AMD FX-6100 and Higher
  • AMD FX-8320 and Higher
  • Intel Core i5-3330 and Higher
  • Intel Core i5-4430 and Higher
  • Intel Core i7-3770 and Higher
  • Intel Core i7-4770 and Higher

Top of the Line Processors

If you absolutely must have the best thing out there for your new computer than this is what you want to look at. It will cost you though. Generally the most recent processors from the manufacturers come at a price premium of about double that of the middle processors. While the price is over double that of the middle processors, the performance tends to be only about 25-50% more at the best of times from their counterparts in the middle category. Often you will see these in desktops priced well over $1000.
