How long does a cpu last?

[kucheri6282]

how long is the life of a quad core cpu?

I can't tell if that's a serious question or not, but there are too many factors (such as OC'ing, heat, voltage, freak occurrences, etc.) to give you an absolute answer. Nobody truly knows, but my own personal belief is that a CPU that is never OC'd and well maintained will long outlive it's usefulness.

CPU's are almost always the last component to fail in a system. Even OC'd, if you're not stupid with it, a CPU will still outlast everything else in the system. My best guess, assuming no freak occurrences like storm damage or something like that, is 10+ years (well beyond its useful life).

Cpu's usually last 7-10 years on average, however other components usually fail and die out long before that.

No doubt the CPU is one of the most solid parts of a machine. It sits pinned down usually all nice and cooled and protected it's whole life. Especially the current chips with all the sensors on the die and shutdown before damage features that you get.. it's almost impossible to just kill one unless you do something absurd. Even a bad overclock will just trip the sensor and you reset the cmos and try again. No big deal.

Longer than the period of time before you will want to upgrade it.

I'd be more worried about HDD/SSD, motherboard, power supply, and even video cards not lasting long enough than the CPU. It's usually the longest living part and when it dies, it's usually because of another piece of hardware killing it (such as the motherboard or PSU), rather than it having a failure of it's own.

I can't tell you how many first gen p4's are still alive in this world.. that's well over 10 years right there.

 

[gamerk316]

PIII's are still at full chat...

My "family PC", powered by a Intel 386, is still alive and kicking...

 

[eddieroolz]

I still have Pentium 66MHz sitting around that works.

 

[rajyohanson]

Nice. I used to have a 386.. IBM baby.. SX33 4mb RAM. 640k base.. 20mb harddrive. That thing was LOADED.

Most actually got more than enough life in them to outlast any usefulness. The longest running life of any cpu is closing in on the 40 year mark in the voyager space probes. For a typical home pc and office workstation the typical life is around six years before being tossed out but often kept around yet longer. The oldest running comp that I got at the moment is a old 486 dx2 running at 66 mhz stock.

For a quad core in terms of usefulness my guess maybe till 2016-2020 tops.

My list of currently still known-good PCs:
- 14 years old P200-MMX/256MB, about 8 years of 24/7 service behind it and still working last time I put a PSU in it
- 12 years old P3-1066/512MB with about 12 years of 24/7 service behind it, still in 24/7 service
- 12 years old P3-650/512MB with about 8 years of 24/7 service behind it, still using it occasionally
- 8 years old Northwood P4-3000/3GB with about 6 years of 24/7 service behind it, still using it occasionally
- 4 years old C2D-E8400/8GB with 4 years of 24/7 service behind it, still in 24/7 service as my main PC

I have yet to dispose of a motherboard/CPU due to hardware failure, all those I threw a few away (8088, 386SX, 486DX, P100, P200) were simply due to not having any further probable use for them.

So yeah, properly cared for CPUs tend to have much longer lifespans than their performance and expandability is generally considered acceptable for.

I still have two Pentium 4's in a Dell and Compaq that run perfectly fine. The reason they've been replaced is because all the other parts mostly the motherboard are too old and obolete now. They have no PCI-e slots no DVI plug limited number of USB 2.0 (only two), all data connections are IDE and lack of other peripherals and features. Other than that the CPU works fine. It's slow and hot compared to the Sandy Bridges but it still works.

I wouldn't say my P4 was missing any major features other than support for more than ~3GB RAM and sufficient processing power to decode 720p h264... it had 6x USB2 ports, FireWire, multi-format card reader, the graphics card has dual DVI outputs, SATA and just about everything else needed. The lack of PCIe isn't really a big deal since the P4 would lack the processing power and RAM to run most newer games smoothly anyhow. Motherboards not having DVI back then was perfectly normal since the G-series chipsets had horrible drivers and even worse performance so they were completely worthless for any form of remotely serious gaming and people avoided them like the plague.

Other things that contributed to the P4's quick demise were high power usage with Prescott and horrible IPC throughout the Netburst product line with AMD's Athlon running circles around them... things turned back in Intel's favor with C2D and i3/5/7. Netburst (P4) was a neat concept but Intel's first go at it turned into an embarrassing failure overall - though some concepts still live on in Core2/3/5/7 so Netburst wasn't a complete write-off.

Yes no kidding thats what I'm saying. It lacks all that stuff that computers come with today making it obsolete. The other hardware went obsolete long before the two Pentium 4's which are still working over 10 years later.

 

[rajyohanson]

Yes the p4's were smoking hot, and they took them to absolutely insane frequencies at the time.. I mean they touched 3.8ghz stock at one point.. I know I bought an ath64 at the time.

More precisely, Prescott was smoking hot, breaking new TDP records without significant performance improvements over Northwood.

Willamette and Northwood were not too outlandishly hot compared to other chips of their time.

 

[Jowiso]

Agreed. I'm on a Core 2 Duo that I've been running since release - no sign of age, yet my MOBO and monitor have both failed me within that same timeframe.

A CPU can physically survive for many years. My IBM ThinkPad T40 purchased back in 2003 has a Pentium M 1.5GHz CPU. The laptop still works.

If you are asking how long a quad core CPU will last you before you need to upgrade, then that depends on how much performance you expect from it years later. If all you do is surf the net, do office work, watch videos, then a quad core CPU bought today should still be enough for what you need in 2020.

 

[Abhraneel Roy]

I have a OLD PC on which has a AMD Sempron LE 1200 and it still works perfectly !
Its been 9 years an still works !(From the Day of Release)
