Buyers Guide for Best Best Intel i7 CPU 2017

The most important component of a computer is the CPU or Processor. Processors may seem simple on the surface, and they aren’t that complex to understand, at least not as far as purchasing for performance goes. But in truth, processors are much more than they seem to be. The best way to compare it is to do the analogy of a car. The motor of the car is the CPU of the computer, like the motor there are different parameters that will determine how well perform doing tasks.


For instance, just because a processor has a higher frequency or more core does not mean that it’s better than another processor. In fact, clock speeds and core counts really only accurately compare across similar processors from the same company. Generational differences can significantly widen the performance gap without changing anything about the core count or clock speed. This misconception exists because with the dawn of the 21st-century processor clock speeds and core counts actually did matter a lot. Once upon a time a processor reaching even 800 Megahertz was a crowning achievement, so having multiple processing cores was even more impressive.

However, with the progression of technologies, clock speeds and core counts have reached certain physical limitations, mainly related to heat and power consumption. These limits will be overcome over time with new technologies, but for now, processors have a few hard limits in place. (For instance, consumer processors top off at 3 – 4GHz, while overclockable processors can temporarily be run as high as 9+GHz with a temporary solution like liquid nitrogen cooling.)

So keep the following in mind when buying and comparing processors:

  • Clock speeds and core counts do count for something but usually only between members of the same hardware family. Only compare clock speeds and core counts between processors if they’re of the same brand and are made within a minimum of a few years of each other. Even then the newer processor with the same core count and clock speed will still have some level of incremental comparisons.
  • When buying a processor to upgrade your CPU, use Device Manager to learn what processor you already have. To do this on Windows, type in “Device Manager” in Start and open “Processors” to learn the name of your CPU. From the name of your CPU, identify what CPU slot your motherboard uses – you will only be able to upgrade your CPU to other CPUs in that slot. You may also need to upgrade your BIOs as well, depending on when the series was released.
  • If buying a processor for an entirely new build, go for the newest series from Intel or AMD. At the time of writing (late 2015), AMD’s current desktop architecture is the Ryzen series, while Intel’s is Skylake.
  • The production orientated CPUs are the ones with more cores.

Once you’ve decided what range and line you want to be shopping in, there are a few other things you need to take into consideration as well.

  • Is it overclockable? Overclocking a CPU will get more performance out of it at the cost of higher power consumption, thermal out, ut and potential system instability. This isn’t recommended for inexperienced users but can provide a great performance boost if done properly.
  • Does it come with a cooler? Often forgotten, but still very important, if you don’t plan on using a water cooler or something, you should check whether or not your processor comes with a cooler. If it doesn’t, you’ll need to buy your own cooler, and you’ll have to make sure it’s compatible with your build. Most processors come with a cooler in the box, but you should still check, just in case. (Don’t operate without a cooler – you will destroy your processor.)
  • Is it upgradeable? We went over this earlier, but it bears repeating: if you plan on upgrading, don’t just buy for now. Right now, AMD processors would be a poor choice if you plan on eventually upgrading your system to the certified Best Ever™, while AMD still has quite a few generations to go before changing sockets. Your CPU socket will determine your potential upgrade path – try not to buy processors that only support dead CPU sockets.

Buying a processor can seem like a really dense, difficult thing to penetrate. With any hope, this buyer’s guide helped make things at least slightly clearer.
