Intel uses a letter at the end of many desktop model numbers as a way of classifying different processor product lines (i.e. i7-6700HQ, i7-6820k, etc). Here’s a quick breakdown of the most common and what each means.
U – meaning “ultra-low power,” these processors are typically found in Ultrabooks and similar style laptops where battery life trumps performance. TDP is usually around 15W but speed suffers.
HQ – designated for “High performance graphics, quad core,” HQ processors are found in many gaming laptops like our Raptor MX70. TDP is around 45W but performance is much better.
HK – meaning “High performance graphics, Unlocked,” these processors are similar to the HQ class but can also be overclocked like many desktop processors. Due to the cooling limitations of mobile platforms, it’s not something we recommend though.
K –a desktop processor that’s unlocked and can be overclocked by either the OEM or end user. This post on locked vs unlocked goes into more details.
T – Intel describes this product as designed for the “power optimized lifestyle. ‘T’ class processors are similar in terms of specs to the HQ line but are typically found in All-in-One PCs.
None – Processors with no alpha suffix are desktop processors with no specific designation. But they’re important too!
