Intel Core i7-14700K has an 8P+12E Core Configuration

I bought the motherboard on June 7, 2022. It entered its second year.
Why would I change it now?
Why would I change the processor (12500)?
You always cling to extremes. Most people don't buy i9/r9 initially, but they can upgrade years later to them at a much lower price.
Example:
8600K in 2018 at ~$225
9900K in 2023 for under $200 (SH). I think you can find it for around $150 if you insist on keeping a motherboard with an expired life expectancy.

But you can keep that base plate as long as you want.
Do I really need to remind you what mess AMD made with processors and compatibility on AM4? Those who wanted Ryzen 5000 at launch (very expensive) had to upgrade their motherboard as well, because the old models received compatibility a year later, and not from AMD but from the manufacturers.

That was my exact upgrade path, 8600k, then not long later 9900k on same board.

Actual difference in efficiency, 6%.

But how is this relevant to the 7700x?

Definitely not!
The 13500 slightly exceeds the 7700X in multicore applications (like Cinebench, CPU-Z), consumes less and is much cheaper.

You're giving BS examples, someone with a 6700k couldn't upgrade to a 9700k 3 years down the line even though they were the exact same uarch! Who said anything about i9 or whatever?

Yeah good luck getting a board for 9xxx cheap today! What does 3xx or 4xx AM4 board cost these days, brand new or old?

Admittedly the earliest Zen chips weren't exactly great but the platform has been solid overall. And don't need to remind you AM4 was released before 8xxx gen chips came out

8th was launched in 2017, with a price shock. The 8700K ($357)equaled the 1800X ($500) in multicore applications, crushed it in single core and gaming applications and was launched with an unbeatable price. The 8600K, launched in the same year, doesn't look bad either. Ryzen 5 price and much higher performance in gaming.

Your variant with the motherboard does not work. You could upgrade 2-3 years later to 9700K or 9900K using the motherboard bought in 2017.

I don't really understand what savings you make if you keep the motherboard and change the processors like panties.

It works if you get in at the start or early in the platform cycle in the low or mid range that meets your needs and toward the end max out when there are heavy discounts before the parts get locked into higher pricing because of increased rarity or scalping. For example if you got a 2700x/3700x 4 years ago with a decent board then today you can get 5950x for $390 new egg special. This however is more of an example of careful/strategic upgrade planning and why a lot of AMD users got so upset when 5000 series looked like it wasn't going to get supported on older AM4 chipsets. If AMD does better with policy in AM5 you could conceivably get in at 7600/7600x (with the increased platform cost over AM4) and end the cycle with an 7950x/8950x/9950x or 7800x3d/8800x3d/9800x3d as AM6 enters the scene and previous gen parts get discounted making up for the higher cost of the initial buy in plus some savings on last gen parts.

You're making some sense there. I've never understood why "platform longevity" is such a big thing for some people. By the time you actually need a CPU upgrade, you most probably have to change your motherboard as well, whether Intel or AMD. Sure, AM4 has been around for a very long time, so you could potentially upgrade an 1800X to a 5800X3D, but chipset vs CPU compatibility wasn't always flawless. If memory serves, it took AMD something like a year to figure out Ryzen 5000 support on older chipsets, so if you wanted such an upgrade, you probably got a new board anyway.

On the other hand, if you want a CPU upgrade with every generation, then saving money isn't your main motivation in the first place.

That does make sense. If you keep your system for the long haul you don't upgrade as much as replace your whole system which can be very cost effective as well depending on if you want/need the bleeding edge or not. What doesn't make sense is to do CPU upgrades for anything less than 30% total performance uplift. You can even argue that percentage should be higher or your just wasting money.

Yeah, b350 and x370 were able to use zen 3 only 2 years after zen 3 was released. Was patiently waiting with my b350 until I decided to just buy a new mobo. To add insult to injury, some amd cpus cost as much as equivalent intel cpus WITH a brand new mobo included. Like, the 5800x 3d alone cost as much as a 12700f + a brand new b660. That's absolutely nuts..

Like going from 12600 to 14900k?

I see the argument from both sides, if you someone who likes to swap CPU a lot, then AM4/5 system works well, but for some people as well they perhaps keep their platform for multiple generations in which case a board that lasts 3 years as a supported platform isnt as important. The AMD system even if not planned can work out wonders though as someone on zen or zen+ has a very nice upgrade path now, I seen the benefit myself going from 2600X to 5600G.
