Strongly disagree here
For the vast majority of users, a 12th-14th gen at a great price point would be an excellent build(Same for AM4 build). Just because the platform is "dead end" is of little value importance to the majority. I Personally ran a Ivy bridge from 2012 till 2019 until I upgraded to a 9900KF(Grateful I skipped8th gen...). I went through many GPUs but the platform was more than serviceable and still is living on as a plex server out in the wild.
I would concede that the existence of the R7-5700X3D does make AM4 an interesting option but not LGA1700. Just look at how LGA1700 gets left in the proverbial dust when it comes to an i5-14400 build:
LGA1700 (DDR5):
CPU: i5-14400 - $230
Motherboard: ASRock B760M-H/M.2 - $90
RAM: Team Group T-CREATE EXPERT 32GB (2×16GB) DDR5-6000 CL30 - $98
TOTAL = $418
AM5:
CPU: R5-7600 - $189
Motherboard: ASRock B650M-H/M.2+ - $100
RAM: Team Group T-CREATE EXPERT 32GB (2×16GB) DDR5-6000 CL30 - $98
TOTAL = $387
LGA1700 (DDR4):
CPU: i5-14400 - $230
Motherboard: Asrock H610M-HVS - $70
RAM: Silicon Power GAMING 32 GB DDR4-3200 CL16 - $54
TOTAL = $354
AM4:
CPU: R7-5700X3D - $230
Motherboard: ASRock B450M-HDV R4.0 - $60
RAM: Silicon Power GAMING 32 GB DDR4-3200 CL16 - $54
TOTAL = $344
LGA1700 DDR5 Situation:
The i5-14400 would be in about a dead heat with the R5-7600 in gaming because it's slightly slower than the R5-7600X, just like the R5-7600. However, the power consumption would be starkly different and not in Intel's favour. The R5-7600 also comes with a usable cooler as well so that's another $30 you don't have to spend in addition to the fact that the AM5 platform is already $30 less expensive. Then of course, there's the upgrade path which may not be advantageous today, but five years down the road.... it will be. Remember that AM4 is in its
eighth year and even if AM5 doesn't last as long (it probably will though), it's pretty much guaranteed that the next upgrade many years down the road will be another AM5 CPU.
LGA1700 DDR4 Situation:
The AM4 setup here just destroys the LGA1700 combination because the i5-14400 can't hang with the R7-5700X3D when it comes to gaming and it's not even close. The 1080p Geomean in Tom's R7-5700X3D review shows that the i5-14400 averages 125-130FPS while the R7-5700X3D just clobbers it with an average frame rate of 159. The AM4 setup will also use less power (X3D CPUs are NOT power-hungry) and costs $10 less.
Building a new LGA1700 PC from scratch would be a bad idea no matter how you look at it whether you strongly disagree or not. If you have numbers to back up your position, I'm willing to read them but I just don't see it happening because I already tried.
