Best Desktop CPUs

By , About.com Guide

Nov 29 2011 - There are a large number of desktop processors available and this list was generated to point out the three major categories of processors for both the Intel and AMD product lines. The three categories listed are the top performance processors, best value processors (<$250) and best budget processors (<$100). This allows users to select the CPUs best suited to their budgets. If you are looking at purchasing a fully built desktop computer or building one yourself, check out which processors you should be looking to fit your price range.

AMD Performance - FX-8150

After what seemed like an eternity, AMD has finally released the first of its new Bulldozer processors. As with their past models, AMD has really stuck with the more processors is better approach. The new FX-8150 features eight processor cores which is two more than their previous desktop Phenom II X6 models. It also features a faster 3.6GHz processing speed which should help it out. Unfortunately, the performance gains are actually quite minimal and only best suited for the extreme applications that can take advantage of so many cores. In fact, most gamers would probably benefit more from the value series model. Still, if you are heavily into crunching numbers or serious video work, then this processor might help you for a price under $300. The best part, it uses the same Socket AM3+ motherboards as the past Phenom models.

Intel Performance - Core i7-3930K

Technically, the new Intel Core i7-3960X is the fastest processor from Intel for a desktop PC, but the $1100 price tag compared to the i7-3930K at $600 for just 100MHz speed difference just doesn't make sense. Both of these chips use the new Socket X79 platform that is Intel's latest performance chipset. This gives some tangible benefits to the new Sandy Bridge-E processor with the inclusion of quad channel memory for some incredible memory bandwidth. The i7-3930K also features a hexa or six core design unlike the more common quad core designs of the traditional Sandy Bridge. This helps it achieve better performance for those with extremely demanding computing needs. Unlike the other Sandy Bridge models, there is no integrated graphics built into the chip requiring a dedicated graphics card. It should also be noted that this processor runs quite hot and does not come with a supplied cooling solution. It is advised to use a high performance option to ensure a properly running system.

AMD Value - Phenom II X6 1100T Black Edition

While the AMD Fusion line melds the desktop processor and graphics into a single chip, it does sacrifice a bit of performance to achieve the integrated design. Because of this, the older Phenom II X6 1100T actually offers a bit more performance for those looking to get some solid value in their desktop PC. Now, it will mean that you have to have graphics on the motherboard chipset or a dedicated card, but that is fine with many looking at this price segment. The processor features six cores rather than four. This gives it certain advantages over quad core processors when heavily multitasking or using multithreaded applications. While the AMD processor won't give the same level of performance as Intel's, it still is a great way to get multiple cores without having to spend a fortune. The processor uses the Socket AM3 processor and is unlocked for overclocking as per all of AMD's Black Edition models for easy overclocking.

Intel Value - Core i5-2500K

Intel may have killed off any reason to buy a high end processor with the new Intel Core i5-2500K processor. This Sandy Bridge based processor uses the LGA 1155 socket design and comes with the new Intel HD Graphics 3000 on-processor graphics. It features quad cores with 4MB of cache and best of all is fully clock unlocked. Even without overlocking, this processor can top the older i7 generations in many tasks. Pair this processor up with a P67 or Z68 based motherboard and this processor can easily overclock a full gigahertz over the base 3.3GHz speed with little effort. With so much performance, there is almost no reason to spend more unless you need Hyper-Threading support.

AMD Budget - A6-3500

AMD has made a huge push for their Fusion APU processors. This is a melding of their central processor along with AMD's Radeon graphics core. This offers a very affordable entry for desktop computers with better than average integrated graphics. The A6-3500 is a triple core processor that adds an extra core to help improve performance over a traditional dual core processor when it comes to multitasking and demanding tasks like digital video which tend to be multithreaded. The graphics are the Radeon HD 6530D that can handle Direct X 11 graphics and casual PC gaming. The one downside is that it uses the newer FM1 socket design so it doesn't work well as an upgrade from the previous Phenom/Athlon motherboards.

Intel Budget - Pentium G860

Intel's primary socket design right now is the LGA 1155 used with the Sandy Bridge based Core i processors. The only problem here is that even the most affordable Core i3 processor is over $100. To resolve this problem, Intel has introduced a new series of Pentium G processors to offer the most affordable processors. These processors are based on the Sandy Bridge with its Intel HD Graphics 2000. It is a dual core design with a 3.0 GHz clock speed. It does not feature Hyper-Threading and has a limited 3MB of cache but the efficiency of the new core gives it a good boost over the past Pentium G6950/G6951 for best Intel budget processor.
