Anna Nova Posted July 2, 2022 Posted July 2, 2022 Interesting that you talk about 'useful life', I wasn't aware that electronics got old by use. Can you point to info on that? I sort of thought that computers got slower because the software got more complex...

Below 18nm IC line width, a new wear-out phenomenon appears. NVidia 1060 GPUs were at 16nm. NVidia 3xxx GPUs are at 7-8 nm. 3-5nm in the next few years. Becoming a major problem, especially in automotive. This is the price paid for smaller transistors. Discussion for gamers. Overclocking bad. Fan bearings wear out. Thermal paste between heat sink and GPU matters. Fans matter a lot. It's use time that matters, not just time sitting around. Current NVidia warranty period: 3 years. 4 2

Has some interesting points. I also checked the examples (Best Buy) the author listed and it raised a question I have always wondered. I would like to upgrade to a newer GPU. The one I have now is an Nvidia Geforce card I was given and have been using since 2016. Nvidia is still giving me updates. Sadly, I'm unable to give you the exact card model as I'm on my lappy now and the card is in my desktop (maybe post here an update later when I get on the desk). I had the stock power unit removed (180w) and a 450w unit installed. Am hoping to get an I-7 processor (I-3 now) sometime. The desk is an HP and can be expanded. My question is how set in concrete are the recommended power supply ratings? If i purchase a new card that has a recommended power of 500w, would using a 450w power supply make much of a difference?

Richardus Raymaker Posted July 2, 2022 Posted July 2, 2022 Well, it's nice if more cards would be in stock again. But the prices are still extreme to high. Asus 3080 is still above 1000,- euro. 1
SarahKB7 Koskinen Posted July 2, 2022 Posted July 2, 2022 (edited) The GPU shortage is not over. Not by a long way. The day you're able to walk into any everyday electronics shop and see shelves stocked full of GPU's at affordable MRRP prices is when the shortage is over. Edited July 2, 2022 by SarahKB7 Koskinen 1
Flea Yatsenko Posted July 2, 2022 Posted July 2, 2022 https://www.tomshardware.com/news/graphics-card-prices-july-2022 Prices are coming down, big time. The shortage is over in the used market at least. They are going for half of MSRP used when they were above MSRP used. Once we properly enter the recession prices are going to tank hard, people can't afford fuel and food they aren't going to spend $1000 on a new graphics card. They are going to drop further when AMD releases their new graphics cards this fall, they're supposed to be a huge upgrade (Nvidia's will be too) since COVID threw a wrench into product releases and both companies basically skipped a generation. And yes, smaller nodes (nms) are more fragile and not as strong under use. I had an FX 8350, got it to boot at some insane voltages and made it into Windows long enough at 5.3ghz long enough to get a screenshot. My Ryzen, I can barely overclock. Intel has been getting bad too as it gets smaller. At least the smart miners undervolt and underclock for better efficiency, the smarter ones aren't the ones who are pushing their cards to the max, better to mine with two undervolted and underclocked cards that one overclocked and overvolted (power consumption goes up exponentially when you overclock). I had a 7970 (28nm) liquid cooled, I just set basically everything to the max clocks and voltages and used it for 8 years before it died. Wouldn't think about that on a new graphics card, they don't overclock as well and they die quicker. I remember when Intel went to 14nm people who would overclock their higher nm CPUs were killing 14nm ivy bridges like crazy. I actually used to be a huge overclocker and did it for fun, but new CPUs/GPUs are death to overclocking, I don't even really do it anymore, it's not as fun as it used to be and they all die. 1 1

Transistor aging isn't just limited to smaller node sizes, although in older tech it takes far longer than the devices usable life to present a problem .. much to the chagrin of retro computing enthusiasts. 6 hours ago, Schatzi Timmerman said: If i purchase a new card that has a recommended power of 500w, would using a 450w power supply make much of a difference? You're thinking about power supplies backwards. A 450W PSU doesn't push 450W down the wires, it has the potential to supply 450W when stuff demands it. A power supplies rated output represents a maximum potential rather than a constant output. Think of it in terms of peak availability, you have the potential to supply 450W but your system might not use even a fraction of that most of the time. But for the brief moments when it does need 450W, the power supply can deliver. Getting a lower wattage power supply creates a situation where it's run at or above it's rated potential output which will dramatically shorten it's lifespan and cause system instability. You also need to factor in power usage spikes. Sometimes a component that's rated for an average of 200W might try to pull 300W (or more) for a very brief moment, if your power supply doesn't have that spare capacity on hand then then system will glitch, crash, blue screen or just hard reset on you. Always buy a much bigger power supply than you need. Overkill is your friend and will save you money in the long run. 2 2

I have no idea which generation of Ryzen you are using but 'overclocking' in the traditional sense is different with these cpus . They are pretty much maxed out of the box unless its a low end Ryzen. They respond very well to 2 things, good cooling, obviously, and undervolting. It's a process but once you find the sweet spot for undervolting and the PBO settings in bios, they are truly amazing chips. (using a 5600x myself)

Anna Nova Posted July 2, 2022 Posted July 2, 2022 There was a British engineer in the 1940's, Tommy Flowers, who discovered that if you got a Thermionic Valve (I think there is an American word, but I forget it) Computer working, and never turn it off (and on), it kept going almost forever. Valve's were replaced by transistors in the 1950/60s, because valves were 'unreliable' (Flower's work was subject to Official Secrets Act). That's Tommy Flowers who built the first stored program computer, and didn't get the publicity that Turing, and of course the Americans, did. Maybe we need to stop power cycling the little buggers. 1

If you do at least some basic maintenance (like dusting, thermal paste replacement, working cooling parts) the stuff can last for years, unless you're constantly running the PC hard for extended sessions. My 4-year-old GTX 1050 laptop still works great with few issues as I dust it out once a year + I clean the cooling pad every 2-3 months. I wish we could stop power cycling stuff, but think of the environment in general. And Ye Olde Power Grids... Edited July 2, 2022 by JeromFranzic
Jackson Redstar Posted July 2, 2022 Posted July 2, 2022 I recently bought a 3070 to replace my 1080 after waiting about a year because of the insane GPU prices - but in SL - ZERO difference in FPS. Defenitly a law of diminishing returns applies to SL. it renders my videos way faster so there is that! 1 2

The degradation mechanisms for vacuum tubes are different than for solid state devices. While there are components in power supplies that are stressed by power cycling, that stress will be compensated for by a good designer. The rest of the system is generally insensitive to power cycling, and ages entirely due to on-time and operating (or even storage) temperature. If you aren’t using it, shut it down. 3

Power-on failure is a very common phenomenon, and as Coffee mentioned, it's usually the inrush current that on-board capacitors are demanding that is the culprit. Simply upping the power supply won't stop that happening though. Most electronic devices have a shorter lifespan when worked at an elevated temperature. 2

Overkill is your friend and will save you money in the long run. There's also Murphy's law of PSU failure. It always lets the smoke out on a holiday weekend. Failure may seem easy to fix, and a PSU has plugs and sockets for connections, but there's still a fair bit of your time spent on taking out the old and putting in the new. How long do you spend on getting a replacement? But if you have a margin, a PSU can last a long time.
