Intel Processor Suffix §

The suffix (trailing letters or letter and number) give you more information about where the processor sits in the range. Our suffix in our example is Core i5-1145G7,for example, but there are other variations including the i5-11300H and the 11600, which has no suffix at all. Below is a list of the common suffixes you’ll find.

• No suffix: This is a standard desktop processor, generally with four cores and a high clock speed for excellent everyday performance and the ability to edit videos and photos at high speed.
• K suffix: The highest-performance processor you’ll find in a computer you can buy on the high street. Similar to a chip with no suffix, but generally with a higher clock speed. These chips can be ‘overclocked’ by those with technical knowledge.
• HQ suffix: Generally found in powerful laptops and normally come with four cores. Perfect for video and photo editing, but sacrifices battery life and portability.
• T suffix: Found in smaller desktops and all-in-one PCs. These chips are functionally the same as those without a suffix and have the same number of cores, but with a slower clock speed.
• G and a number at the end: Processors from the 10th-generation onwards (models starting with, 10, 11 or 12) often end with a G and a number, for example, G1 or G7. The higher the number on the end, the better the built-in graphics chip on the processor will be. The product listing should provide more detail as to what sort of performance you can expect.
• U suffix (older chips only): ‘Ultra’ low power. These chips generally have two cores (although newer models now have four cores) and are among the slowest processors with Core i branding. These chips can often be found in cheaper AIO PCs and in many laptops. They can be suitable for photo and video editing, but tend to be a lot slower when performing tasks such as exporting files to disk. If you’re looking for a photo-editing machine, pick a Core i5 or even try to stretch to an i7.
• Y in the middle (older chips only): Y are the lowest-power chips you can find. They aren’t really suitable for photo or video editing but will be fine for lighter tasks. The advantage of choosing one of these is very good performance for lighter tasks, coupled with a longer battery life. Laptops that use this chip tend to have fanless designs, meaning they’re totally silent and very thin.
