CPU Longevity Experiences

Commenters share stories of using CPUs from 5-15 years ago without needing upgrades, noting plateaued performance gains in new generations and preferring targeted upgrades like SSDs or GPUs instead.

Just checked and I've been using my CPU for 6 years, and have no immediate need to upgrade

Making the CPU consumable is a smart from their PoV since the rapid increase in performance every generation has plateaued.I still do all my development at home on an i5-2600K and an i5-2430 laptop, neither is noticeably slower than any of the new machines I've used (both have SSD's).I'll probably run this desktop til it dies as there is no compelling reason to upgrade.

New CPUs aren't much faster than the old ones. Going from an i7-6700k to 7700k to 8700k to 9700k gets maybe 10% faster single threaded performance on each step. GPUs are starting to show a similar story. Those Geforce RTX cards barely faster on a dollar-per-dollar basis than their predecessors. Unless you need the transfer speeds, those hot new NVME SSDs aren't noticeably faster than SATA SSDs.I would building a PC right now, but the one I built two years ago is fine.

> Writing to disk is fast and my internet is fast. Things feel super snappy. I've been building computers from parts since about 1998, I think this is the longest I ever went without an upgrade.I did like you: rocking a Core i7-6700 from, what, 2015 up until early 2022. 16 GB of RAM, NVMe PCI 3.0 x4 SSD, the first Samsung ones. I basically build that machine around one of the first Asus mobo to offer a NVMe M.2 slot.It was and still is an amazing machine. I gave it to my wife an

I got the top-end i7 about 5 years ago, it's still fast. I have tried to justify upgrading it many times but I just can't see the benefit in replacing it with something that's just a bit quicker.I can at least upgrade the SSD and GPU without throwing the whole damn thing out, but even then it's hard to justify.

Same here. I got mine five years ago when I needed to upgrade my workstation to do work-from-home, and it's been entirely adequate since then. I switched the CPU from an AMD 3900 to a 5900, but that's the only upgrade. The differences from one generation to the next are pretty marginal.

I'm still using the same CPU I had 15 years ago. It's an AMD Phenom II X6 1090T. The only upgrades I've made are increasing the RAM to 16 GB and replacing the hard drive with an SSD. It continues to meet all my needs.

CPUs have been progressing faster in the last few years, mainly because of AMD's Ryzen line. In laptops, 4 cores are now standard, and if you can gen one of the AMD 4000U CPUs, 8 cores with good single-threaded performance are relatively cheap. Same thing on desktop, you can get 20%+ more performance by upgrading the CPU.Sure, it's not the same as 486 vs Pentium, but the Ivy Bridge-era CPUs that were used for such a long time are now equivalent to low-end CPUs, it's no longer u

My overclocked 1st gen i5 is about half the speed of a brand new mid range processor. It's almost 7 years old and I still have no need to replace it.I've considered getting a new PC for SATA 600 and USB 3.0 more than I care that I could have a new machine that's only twice as fast.

Laptops are consumables. By the time you want a CPU upgrade (let's say 2-3 years or even more), isn't it likely you want to replace the whole machine?
