    Obviously if you have to choose between a 7700HQ and 1070 and 6700HQ and 1080, you choose the 1080. But both processors are going to seriously destroy your minimum or maximum framerates. A 3100 mhz 6700HQ is slower than a 2600k @ 4.5 ghz. A processor more than 6 years old. Yes it's playable, but unless you're only playing games which hammer the GPU extremely hard, eventually the HQ is going to choke on something.

    You guys really should not ever put yourself in a position where you have to choose "should I choose to jump into the frying pan or the fire?" unless you're getting a massively huge discount--or pricing error. People who buy the GTX 1080 are buying a GPU because they want a GPU that has legs. A 6700HQ has stumps. And a 7700HQ has slightly larger stumps. Or you can say, your engine (horse) is a mustang that's towing a chariot, but the chariot has square wheels. Yeah.

    Both have an absolute 45W unavoidable power limit, which can only be exceeded by very difficult methods (hacking the EC registers, tricking the CPU to report less wattage than it's actually using (Negative Imon offsets, if you even have access to this) or undervolting it considerably.

    I do not understand this obsession with CPU. Time and time again, for at least the past 15 years, minor differences in CPU clock speed across the same CPU generation & CPU wattage does not yield noticeable real-world performance difference in general application usage or gaming.

    The only time you'll notice a difference is when you are running very specific CPU-bound applications; such as CPU benchmarks; CPU-based video encoding; or CPU-based professional applications like simulation modeling and BI reporting. Overall features (e.g. core count, hyperthreading, thermal envelope, power management tech to manage sleep states, etc) across the same CPU generation matter more than clock speed for real-world performance.

    Most games are GPU-bound (and not CPU-bound), meaning there isnt going to be a real-world difference in game performance. Even among those very specific CPU-bound games (mostly strategy games with heavy game AI processing, like Civ 5/6 and StarCraft 2), you're not going notice a difference between two similar CPUs with minor clock speed differences, unless the only thing you do with your games is benchmark them.

    For a laptop, minor differences in CPU performance is a pretty low priority. There are so many other factors that DO matter to the real-world usage experience of a laptop, such as weight, size, battery life, display quality, GPU (if you game or run GPU-accelerated professional apps), connectivity ports, connectivity features, storage connectivity, memory slots, warranty, build quality, security & remote management features for business-class laptops, etc. That's why laptop manufacturers don't focus much on the CPU. Laptops just needs a CPU with "good enough" performance, which is usually determined by CPU generation (which indicates IPC) and core count, and not clock speed.

    So unless you frequently run a CPU-bound application like CPU-based video encoding, CPU-based modeling, desktop BI / analytics software, or databases with very specific usage patterns, then minor differences in CPU speed are irrelevant (assuming equivalent CPU features like core count, hyperthreading, TDP, etc). If you aren't one of those people, then just be aware that the only benefit you get from slightly higher CPU speeds is to get higher benchmarks for bragging rights, or to satisfy an OCD desire to have "the best" simply because it's the best. You will not notice any real-world difference.

    or bragging rights

    The only reasons people care about minor differences in CPU clock speed is benchmarks,
