Intel Processor Buying Guide

      Purchasing an Intel Processor

      Purchasing an Intel Processor

      Consider the following when shopping for a computer that features an Intel processor:

      • Match your choice of processor to the tasks you need to perform. For example, if you edit high resolution video footage, then you will likely need the power of a Core i5 or i7 processor.
      • Opt for a processor that suits how you work. For example, if being mobile is important to you, then a hyper-efficient Core m processor could help you enjoy longer battery life than one of the more powerful alternatives.
      • Be aware that Intel carries the same naming conventions across generations. This is particularly important to remember if you are considering buying an older PC.
      • While the processor is a vital component of any device, computer performance is also dictated by the RAM, the GPU (if applicable) and the hard drive. Choosing the right computer is often a case of striking a balance between these components.
      • If your computer does not feature a dedicated graphics card, know that most higher-end Intel processors offer Intel HD or Intel Iris integrated graphics. The latter is more powerful and would be a sensible choice for gamers and creatives.

      Processor Performance

      Clock Speed

      placeholders

      Clock speed (GHz) measures how many cycles a processor can complete in a second. In the simplest terms, the higher the clock speed, the more powerful the CPU is likely to be.

      • A clock speed of 1.5-2GHz is likely to be adequate for most users. This will enable you to perform office tasks, enjoy hi-res media playback and much more besides.
      • Gamers and creatives, however, are likely to need more power. Clock speeds in excess of 3GHz should be enough to run most software and games to a high standard.
      • High-end Intel processors also boast Turbo Boost technology, which enables the processor to run efficiently when not under duress and achieve high clock speeds when required. This is especially useful in mobile devices where battery life is key.

      Cores

      Cores

      Processors are often sold according to how many cores they have. Cores are best thought of as the brains of the CPU and the more cores that are on hand, the more tasks can be completed at once.

      • Dual-core processors are likely to be adequate for most users. If your usage is limited to everyday tasks, watching high resolution media and casual gaming, a dual-core processor could be all you need.
      • If you perform processor intensive tasks like high frame rate gaming or 4K video editing, you are likely to need the power of a quad-core processor. 4 cores are likely to be enough for most tasks so you can enjoy computing without limits.
      • High-end Intel processors boast hyper-threading technology. This feature uses processor resources more efficiently so multiple threads can run on each core. This is effectively like doubling your core count when running compatible software.

      Cache

      Cache

      The CPU cache is the processor’s on-board memory. The more memory available to your CPU, the less it needs to communicate with the computer’s slower RAM, the faster the performance will be.

      • Cache memory is graded L1, L2 and L3. L1 is the smallest and fastest. L2 and L3 are larger and slower but the more L2 and L3 cache there is, the faster the computer can run.
      • 2MB of L3 cache storage is likely to be adequate for everyday tasks. If your needs are more advanced, look for a processor with 4 or more MB of L3 cache.
      • If you run specialist software, then you may want to consider processors with 8MB of L3 cache. This will help you enjoy a responsive performance across even the most processor intensive programs.

      Intel Technology

      Intel Core i3, i5 & i7 Processors

      Intel Core i3, i5 & i7 Processors

      These CPUs sit at the top end of Intel’s product line and deliver the power you need to complete processor heavy tasks like high frame rate gaming, 4K video editing and everything else in between.

      • Intel Core i3 processors are perfect for everyday PC tasks, running productivity software and enjoying high resolution media. They boast fast boot times and a battery-efficient performance which makes them well suited for laptops and entry-level desktops.
      • Intel Core i5 processors offer an added layer of performance that is likely to be more than enough for the majority of users. Enjoy 4K visuals on compatible displays, blistering speeds and power on demand.
      • Intel Core i7 chips are designed for the most demanding of tasks such as UHD video editing and 4K gaming at 60fps. They are capable of coping with almost any task you can set them to so you can enjoy a performance without limits.
