Every Ryzen/Intel CPU suffixes and its meaning (including all obscure ones)
You got Intel's T wrong. It's not low power, it's power limited. Basically, same thing as non-T, but BIOS will use lower power limits. These are not more efficient than non-T. It's a common myth over on r/homelab More on reddit.com

April 8, 2020The confusing state of CPU naming
The names are very confusing. Here the main clue is in the last letter - P indicates that performance is the focus while U stands for low power draw (ultra-efficient or whatever their marketing calls it). All components of the name influence what to expect of it, and as you found in this example the suffix can trump the "brand modifier" (i5, i7) when it comes to performance comparison. As such yeah, if performance is your only goal the only reliable source of comparison is tests and benchmarks. More on reddit.com

June 2, 2023What is the difference between U and H in Intel processors?
The difference spans four areas: Performance (H is much more powerful), Power consumption (U is far more efficient — 15 W vs. 45 W+), Thermals (H runs hotter), and Battery life (U lasts much longer). Choose U for portability and H for performance.

What's the difference between an Intel HQ and H processor?
Both are laptop chips with high-performance integrated graphics. The key difference is that HQ historically guaranteed 4 physical cores, while older H models could be dual-core. From the 12th Gen onward, all H-series processors ship with at least four cores, making the HQ suffix obsolete — replaced by H and HX.

Now that we know how to retrieve our processor name and number let us see what each letter in the "Product Line Suffix" stands for. CPUs with the letter K: this indicates that the chips multiplier is unlocked, meaning that it can be easily overclocked if you have a similarly enabled motherboard. Non-K chips have very limited overclocking functionality, so make sure you look for that K if you want to tweak your system. CPUs with the letters HK: Intel doesn't talk about it as much, but the K in HK CPUs that you occasionally see in high-end laptops also means the same thing as the letter K referenced above.
