i think it makes most sense with people who want to try and pair it with 8000 memory on somthing like an Apex/Unify X/Tachyon motherboard.
Like many high end cars, audio gear and homes these 13900KS CPUs are probably a waste of money for those looking to accomplish day to day tasks.
Then there is the entire realm of folks who want a piece of cherry picked gear to play with. Consider these a ticket to ride without as much risk of hoping to win the silicon lottery. DDR5 is relatively new to me. I've probably only built like a dozen systems for myself and clients since September 2022. My first DDR5 system for my own use was a 13700k and some G.Skill DDR5 6400. Well, I never was able to use it at 6400 speeds, instead settling on 5600 RAM speeds. I actually thought I had bad RAM after returning kit after kit discovered it was the nature of the CPU I was dealt (purchased). In February I decided up upgrade my Threadripper 2950x main rig to something more modern. I just could not believe how much more work CPUs can do since October 2018 when I built the Threadripper. Based on my rather annoying RAM experience I spend the extra $200 and bought the expensive edition for $729 in Feb then waited 2 weeks for it to get here. Apparently they are MUCH more expensive now, if you can find one. No matter. I will use this CPU for a few years and if I get tired of it, it gets migrated to one of my other machines around the house or office. I am certainly not wealthy, nor do I care about bragging rights. Given the hardware I have, I really do not even game any more. What I am, is curious about what current state of the art hardware feels like so I can honestly advise clients from personal experience. Would I recommend any of my clients buy a 13900KS? No, probably not. Most people don't need it. I don't even
"NEED" it. I work with computers 6 to 7 days a week. Time is money. I love fast hardware. I love trying new hardware and purchase quite a bit of it for myself or clients. So I guess I am the 1/10 of 1% this might appeal to. Don't get me wrong, I don't buy every single CPU that hits the market just because it's top dog of the day. There has to be something of a perfect storm of the processor: 1- Being much faster than what I was using 2 - Offer new tech such as FASTER RAM, PCI Express and NMVe standards. 3 - I usually only buy a top CPU every few years and not every generation.
The KS CPU's were never about being a mainstream product. There are plenty of other choices that fit people's budgets, workloads, and thermal envelope requirements. I have no reason to badmouth those making choices for whatever reasons they feel is important to them. It's a personal thing. I am just happy there is real competition alive and well since 2017. The 10 or so years before that weren't that good for consumers as Intel spoon fed us 5% increases generation after generation.
