AMD is using a hybrid 7nm and 10nm(?), one size is trace the other is for the gaps between them. Intel uses a true process where the trace and gaps are even. Intel is considering a similar approach and a larger die size in order to stop the bleeding but even if they drop to a smaller size, it will not help computer speeds much. Sure you will see Intel break 5ghz with ease but that's only going to be a small improvement. Clockspeed and cores aren't the bottleneck they once were.
Even if Intel gets a 5.4ghz chip with 32 cores, it's not going to revolutionize your computing. Oh, it will completely crush benchmarks and tear through data and every pundit is going to rave about them but very few things load up a 32core system and if you're waiting on software (the real bottleneck on a modern high core count system), or the internet, most of those cores are going to be sitting idle 99% of the time. Ask anyone with a high core count system how much normal tasks really load them all up. Sure, 8-12 cores smokes a quad core, but that quad probably had a normal SSD and less memory and it certainly had a less efficient chipset. That jump from 8 cores to 12 is flat out BORING, the same with a jump from 12 cores to 16 or 16 to 32. This stuff only benefits very specific use cases. Sure, they are faster, but not as much as benchmarks will lead you to think. How much do you really think you can remove from an 8 second boot or 2 second app load time? Many of us already laugh about reboots, "oh no, I lost 20 whole seconds of my life!"
What it will do however is bring tons of cores to the masses, for cheap, which is great. So when you can get on one of these new systems, do it, it will be the last one you need for a while.
We're actually at a really good point in computing right now for the end user. It's also a good time for AMD and Nvidia, but a terrible time for Intel because even if they come back and take the speed crown it's going to be too little too late. Not because of AMD, but because of ARM. ARM commoditizes the CPU. Do you care about the processor in your game console or your cell phone? I'm sure some do, but most people are just happy if it runs well enough to do what they want and ARM is reaching that point and can be made anywhere by anyone, you aren't locked out like with x86 duopoly. Apple is switching, servers/Linux has already been using it and if Microsoft goes all in on ARM (and it looks like they may) it could wipe out the low to mid range cpu market by the time Intel can really start to regain some footing on AMD. Next gen ARM could take out the entire mid-range and a huge chunk of the server market and once that's gone to ARM it's essentially over for Intel and AMD cpus. Assuming Nvidia doesn't completely destroy ARM.
