thank god. backwards compatibility is the main draw of x86 and with x86 using risc like micro ops for close to 30 years, the whole risc vs cisc debate has been useless.
im just tired of the corporate shilling for arm, they do this whole "x86 is dead" thing every 10 years. first it was itanium, then it was "tablets are the future, no one will use a computer in the future" now its just direct corporate shilling for windows on arm laptops like that hasn't failed at least 3 separate times..
nextgen who was absorbed by amd in the k6 era, pioneered breaking cisc operations down into risc-like micro-ops this has been the standard in x86 designs under the hood. any benefits from removing legacy parts of the isa would only be in die space, which lets be honest is not an issue on such small process nodes

honestly there's probably some esoteric way they can turn off unused portions of the decoder until they are needed. i remember back in the bulldozer days amd had some kind of way of using resonant clock meshing to save power to individual transistors.This article is way too superficial, and only reflects ideas that were true in the past, but have become way more nuanced since them.
In case you want to dive a bit more into it, here are some nice links:
ARM or x86? ISA Doesn’t Matter
For the past decade, ARM CPU makers have made repeated attempts to break into the high performance CPU market so it’s no surprise that we’ve seen plenty of articles, videos and discussions about ARM’s effort, and many of these pieces focus on differences between the two instruction set...chipsandcheese.com
In short: a CISC decoder is more complex, sure, but that complexity is just a really minor fraction of the CPU, both performance, space and energy-wise, and decoding instructions is hardly ever the bottleneck in most core designs, thus the ISA itself is of less relevance when other aspects of a CPU are considered.
