Not sure how true this is but has been my perception.
Intel: all rounder with pricing premium
- less fussy with RAM overclocking
- hotter / more power consumption
- slightly more expensive
- premium models have tended to be hot, expensive but best performance
AMD: cheaper / quirky
- cheaper
- relatively fussy with RAM
- X3D cpus have recently dominated for gaming performance over intel
Not much in it though.
That is generally what the reviews say, the reality is a bit more nuanced depending a bit on what people do.
AMD CPUs tend to be more power efficient under heavy load conditions, Intel CPUs more efficient in lower load conditions* especially when they can put the E cores to one of their intended uses and park the P cores. Power consumption at the wall rather than CPU socket is less dramatically different to what the CPU socket difference would suggest also for gaming the power consumption in reviews is usually at 1080p low settings with a 4090, with the kind of settings people mostly use a 4090 for like 4K ultra, etc. the power consumption difference is much less, especially if using say a 7900 or 4080 series GPU instead of a 4090. So if you really care about power consumption which is best for you may not be so straightforward.
Likewise gaming performance - there is much less in it at 1440p or above with high or ultra settings, compared to the more stark difference at 1080p low settings - the X3D parts tend to be penalised a bit for non-gaming performance so it may in reality be better to look at other options if your usage isn't purely gaming and you aren't doing 1080p 360Hz gaming or something :s
AMD have recently bumped prices on some parts, so which is more expensive has been fluctuating recently.
13/14th gen are overshadowed by ongoing issues - but the reality of that so far seems lesser than the media has made it out to be - the 14900 parts are seeing somewhat elevated return levels but multiple sources show that to be in the region of 3% of CPUs affected, most of the lower models are fairly consistent with normal failure rates so far.RAD Game Tools who where one of the first to discover the issue and have wide exposure to it due to their tools being in a lot of games are still only seeing a small number of affected CPUs mostly 13900/14900s.
The LGA1700 platform is relatively meagre when it comes to things like PCI-e 5.0 provisioning and some other newer technologies/features so that may have a bearing for some people when buying - though IMO both platforms are likely to be rendered obsolete in that respect as a bunch of new standards/features are incoming like PCI-e 6.0, etc.
* In the context of the the main 7000 series / Intel 13th/14th gen desktops - if you want an ultra power efficient system where gaming isn't a consideration or a low consideration then that is a whole another story.
