What determines when a CPU is obsolete these days?


In the past it used to be when even basic use like installing the OS or browsing the web became slow and arduous.


But these days even the oldest CPUs are still fully capable.


And don't say gaming because you can buy brand new low end laptops today that can't play the latest games.

If you have 4C/8T @3.6GHz you are good to go for everything except the most intensive professional workloads, and should be fine for another 4-5 years.

It's obsolete when what you are trying to do doesn't work anymore. This means that obsolescence depends on your use case.

If your use case is shit posting on 4chan, you can use a 15 year old CPU to do that just fine. If your use case is 8k video editing, then you need to have a high end modern 16+ core HEDT class CPU and even 2 year old CPUs are mostly obsolete.
>>
>>79683242
When it is no longer economical to run, if a cpu runs with a higher power than something else to do the same task in the same time then it is obsolete.

Modern cpus have efficient and powerful instructions per core and use less power

>>79683242
>What determines when a CPU is obsolete these days?
when either its too slow or cant do what you need it to

>What determines when a CPU is obsolete these days?
For 24/7 server use: Power consumption.

For casual pleb use: Whether after using a SSD and reinstalling Windows if on Windows, software still runs too slow.
>>
>>79683242
Obsolescence for PC hardware and CPUs in particular doesn't really mean much anymore these days. If it's x86-64 and can run windows 10, you can probably use it for basic tasks like web browsing, office and very light games like among us. Depending on what you're doing though, it could be obsolete because it's missing some specific task instruction or it's just too slow or not powerful enough to finish the tasks you give it in a timely matter or at all. If your shit still works for you, great. Keep using it until it dies. If you don't like it anymore, at least sell it for peanuts or give it away for free and let someone else make use of it instead of thowing it away. Less e-waste is always good in my book.

you need at least 3GHz and at least 6 cores to browse the web now
so, an FX-6100 at a minimum
this is because html5 is vastly inferior to flash in every single way imaginable

You can browse the web on a Pentium 4 just fine, assuming you have enough RAM, and a good adblocker to block bloated nigger JS from raping it to death.

That is possible though, for example Apple drops the M1 in favor of M1X and M2 and stop providing new MacOS and also drops that generation of neural engine support for developers. Now a lot of apps will not run or run slower than a Core 2 Duo
>>
>>79683242
When it can't do what you want it to do.
But not when it's just a little slow, I'm talking about processors that are old enough to be missing instruction sets necessary to run the modern applications at all. Sure there's workarounds but once you get into that territory you should probably just upgrade.

This is a very sad lack of knowledge and I dislike to see it. GHz and core count is a bad measurement standard and far to over simplified. What truly matters is the instructions per clock (ipc).
For example. I'll be using bogus numbers, but the arguement will be valid.
Let's say the 2500k has an ipc of 20.
Let's say the 9600k has an ipc of 100.
Both chips will be manually clocked to 4ghz.
Running at the same speeds (ghz) would show that the 9600k is theoretically 5x the performance of the 2500k. It is simply doing 5x the work in the same exact time span. This is also an overly simplified example. I'd implore people who actually care to do their own research.
As for core count most day to day applications do not support the use of many cores. We'll likely not see a use case where we'll need more cores for a few more years. A 4 core is still perfectly reasonable for household use.
>>
>>79688617
instructions per clock is self explanatory and is also 3 words
>>
>>79683242
we get it.
you can only get a i5 2500k in your country right now and you're mad that people haven't sold off enough of their used ryzens yet because your PC is an overglorified optiplex from an office building that imported women's lingerie from india
just wait a few years, jesus.

Fun fact: In the past when people thought a PC was obsolete it was in fact the HDD or RAM that were obsolete and bottlenecking basic operations. Any desktop dual core will perform desktop browsing and even light office use and light internet browsing to a sufficient degree if paired with enough half decent RAM and an SSD.

>>79683288
>same money
Does that include having to buy a new motherboard and RAM for a newer CPU when you could otherwise repurpose ones from your stockpile if you bought an older CPU?

>>79683407
Desktop operation power usage is negligible in a world where people can afford running four feet wide fridges and the AC for the entire house all day.

It's at least three. The guy making all the threads, the other guy who replied to you, and me. The only 2500K shilling I've ever done was celebrating its 10th birthday last Saturday.

>>79688617
I like to use a truck analogy for explaining processors, cores, threads, and ipcs.
Cores are tractor units.
Threads are trailer units.
Applications are warehouses.
IPC is how much a truck can pull.
Clock is how fast a truck can go.
A warehouse with only one loading dock can only take advantage of one tractor, no matter how many you have. (Single cores, single thread.)
If you have two docks you can either have two tractor-trailers or two trailers and one tractor. Or the tractor can serve two single dock warehouses, delivering one while the other is being loaded. (multithreading and how it's not exactly the same as splitting a core in two).
It's cheaper for the warehouse (the devs making applications) to simply hire a tractor that can go faster/stronger than to invest money into adding more loading docks. (Why applications made in the past few decades only use a small number of cores, it's simply harder to program for multiple cores.)
A newer tractor that is 5x as fast as the old tractor but is 10x as weak will lose in the total amount of work done. An older tractor that is 100x as strong as the nerwer will lose if it is 1000x as slow. (The relationship between clocks and IPC)
And so on.
It's a literal babby tier explanation but it seems to work in the few times I've used it.
>>
I take the i5 2500k as reference. I still use it, but got a 5900x on order for 2 months now.
It has to hold 10 years. Bought my 2500k in 2011 and been using since
>>
>>79688617
IPC hasn't increased as much as you seem to think it has. The 2500K clocked at 4.5 GHz gets 160 points in CB R15 single threaded, so 28 MHz per point. The most recent Intels approach 230 points boosting to 5.1 GHz, so 22 MHz per point, and the most recent AMDs are IPC monsters but still "only" get 270 points at 4.8 GHz, so 18 MHz per point. Effectively therefore IPC has only increased by 30-50% in the last ten years. You can add multithreading to efficiency in a lot of cases, most cases for new CPUs in fact, but far from all of them, and technically it's not a consideration for IPC. Single threaded means single threaded.
>>
>>79688785
That's the most convoluted and involuntarily cute analogy for something I've heard in a while. :3

>>79688812
I wouldn't apply the same expectations to new CPUs. The last decade has been particularly stagnant in part due to lacking competition, and no one who bought a 2500K in 2011 expected it to last ten years when previously you had to upgrade your CPU every four years, if not sooner. Maybe a 12-core will last a while, but in that case it's just due to brute force. The 2500K was a midrange value option.
>>
Only reasons I'll upgrade a CPU:

>I need access to new features of the latest CPU's for some specific workload
>Overlocking incurs energy costs that in less than 12 months could have purchased a new CPU anyway
>The motherboard eats shit and buying used parts is almost the same cost as buying new.

Seems like something nobody is going to actually seek an opinion on unless they're 12 and want to learn how to computer. Everyone else just throws their old computer in the shit bin and buys a new one.
>>
I just set up a refurb HP Elite 8300 SFF for a boomer couple. It's from 2011 and has a i5-3570s, 8gb ddr3 1333, and 120gb Samsung OEM SSD. I was expecting it to be barely usable, but better than what they had. It surprised the shit out of me how usable it actually is for web/office tasks. Even plays 1440p youtube vids without any hiccups. Tech really has been stagnant because a ~10 year old PC in 2011 would have been fucking miserable to use.

When the costs of buying a new machine that can do the same tasks are quickly offset by cost savings due to a lower power bill.

t. someone who upgraded from a desktop from 2009 to a Thinkpad X220 last year and cut about $20/month off their power bill. My desktop literally accounted for half of my total power usage.

>>79688714
>Desktop operation power usage is negligible in a world where people can afford running four feet wide fridges and the AC for the entire house all day.
Except I upgraded and cut a good $20/month off my power bill. I could have dropped almost $500 on a better Thinkpad than I bought and it still would have paid for itself in 2 years.
>>
>>79689280
Where the hell do you live where a shit PC can amount to a +$20 in the electricity bill? How much do you pay for KW/h?
>>
>>79689280
The fuck you running to cut 20 bucks off your monthly electricity? Even with astronomical German electricity prices (30c/kwh) you'd have to reduce your CPU power consumption by 80W 24/7 (not just under load and when the computer is running) to achieve these savings.

At stock the 2500k is not very impressive, but when overclocked it can achieve better single core than Zen1. The only issue with it is the fact it's 4C4T, which really started showing its age recently.
