These suffixes might succumb to change and sometimes used differently by different generations of CPUs but Intel has maintained consistency. Any Intel CPU with the suffix K, for e.g. the Core i7 9700K, means that this CPU is a high-performance part that has an unlocked clock multiplier and can be overclocked with a Z series motherboard, for e.g. Z370. This is true for mobile Intel processors as well for e.g. Core i7 7820HK. If you’re on the lookout for a brand new machine then look no further. Our top recommendations are the Core i7 8700K and Core i7 9700K. Any suffix missed out is highly uncommon.

Broadwell (5th generation) exclusive. Same meaning as K. Has an unlocked multiplier. Processor supports ECC memory. Was used for “efficient” for older Core 2 CPUs on laptops. Ultra low power mobile CPU. Consumes less than 20W on average. Unlocked multiplier on Desktop or Mobile platform. Extremely low powered CPUs. Consume on average only 5W of power. Extreme edition CPU on the HEDT X299, X99, X79, X58 or other. AMD RX Vega M GPU integrated. Yes, you heard that right. By some weird luck, RTG and Intel collaborated to make CPUs for their NUCs (and hopefully laptops). These GPUs aren’t directly integrated, but they are connected via a tiny interface that runs on PCIe and they have their own HBM2 modules for VRAM. Performance of these is a cozy snug between a GTX 1050Ti and GTX 1060/RX 570 on a package smaller than a tablet.

Conclusion

If you have ever scratched your head in confusion, don’t worry. These letters do in fact have meanings. We tried our best to explain them and make your life just a little bit easier. The letters are just a good 2-second guide for you to expect features in case lets say you went to a mall and saw a good laptop at a good price and don’t have access to Intel’s ARK. But it is always wise to see detailed specs of your particular processor before purchase. Explicitly states that this is a Quad core CPU. Isn’t used very much since 8th generation laptops come equipped with 4 cores.   Desktop processor based on BGA1364 (mobile) package with high-performance graphics (I know, I know. An absolute train wreck). High-Performance Graphics. Well, as high performance as Intel’s integrated graphics can get. Not to be confused with Hex (meaning 6 cores) For e.g.   Performance optimized lifestyle. Meaning that the processor doesn’t sacrifice a lot of performance in order to save a significant amount of energy. For e.g Core i7 4770S is a 65W CPU at 3.1 GHz while the 4770K is at 84W at 3.5 GHz. Denotes that this is a mobile(laptop) CPU. Isn’t used very much since 8th generation laptops come equipped with 4 cores. Weaker iGPU on Desktop CPUs for power and cost savings. Especially good for people who already use dedicated graphics. Power Optimized lifestyle Desktop CPU. Ideal for OEMs and low powered PSUs. These CPUs can be used by people who are conscious of how much their computer consumes. For e.g. Core i7 6700T @ 35W.
