x86 is dying. It's dying because of its CISC nature regardless of how much RISC extensions they try to bung on to it carcass. You can NEVER, EVER take out enough of the CISC in an x86 chip to have a power efficient AND powerful CPU. Period. Full Stop. Intel tried with the Atom and it has been an ABYSMAL failure. So much so Intel got out of the Mobile and Tablet market with their tail dragging behind them.
Couple this with the end of Moore's Law as we butt right up against Physics and Quantum effects, CISC based x86 chips and their inherit complexity means they will never get to 3nm without gutting what makes them x86....namely CISC. The transistor / size budget of the die is too hard to do. Hence Chiplets with their corresponding Memory Latency issues.
RISC chips on the other...no problem. Apple Silicon SoCs are shipping right this moment in iPads and later this year iPhones with 5nm SoCs with 2 Big Cores and 4 Little Cores all running simultaneously at running over 2.5 Ghz clock. Along with that there is 128 kb of L1 data cache AND 128 kb of L1 Instruction cache AND 8mb of L2 cache. A 4 core GPU AND a 16 dedicated Neural Processor that can do 11 Trillion Ops / Sec. All of this and more in a 5nm package. Shipping now.
Poor little Intel can't even bung a Neural Processor on their Xeons and have to instead settle for handing out Matrix Math extensions to their AVX vector registers in their Xeons sometime in 2021 if they are lucky and lately they can't even get out of the 10nm starting gate. Even AMD has gotten to 7nm....albeit TSMC's 7nm is more like Intels' 10nm + or at this point should we be calling Intel's process 10nm ++++++++++++++++++++++++++++++ LOL !!!
Sorry my uninformed and backward looking friend. x86 is dying. It's legacy. Apple knows this. Microsoft knows this. Google knows this. By the end of this decade you may finally know this too.
