I believed that until I realized I couldn't individually upgrade my CPU or RAM because I have a mobo with LGA1150 socket and only supports DDR3 (and it's only 6 years old).

So eventually you still have to "replace everything" to upgrade a PC.

View on HN

You were unlucky to buy ddr3 near its end of life then (like someone buying ddr4 now), but you could still upgrade stuff like your GPU or drives independently. My first SSD (a 240gb Samsung 840) is still in service after 9 years with its smart metrics indicating only 50% of its expected lifetime cycles have been used, for example.

You could also put a 4790k, 16gb of ddr3 and a modern gpu in that system to get a perfectly functional gaming system that will do most titles on 1080p high. Though admittedly we've passed the point where that's financially sensible vs upgrading to a 12400 or something as both devil's canyon CPUs and ddr3 are climbing back up in price as supplies diminish

Right now not many DDR5 boards. In fact none for AMD

DDR4 was released in 2014, which would suggest you purchased your mobo two full years after DDR3 was already deemed legacy technology and being phased out.

Also LGA1150 was succeeded by LGA1151 in 2015, which means you bought your mobo one full year after it was already legacy hardware.

Yes, they entered the market around those years, but what does that change? DDR3 and LGA1150 were not deemed "legacy" the day DDR4 and LGA1151 motherboards entered the market. They were 2-3x the price, and DDR3 dominated RAM sales until at least 2017. In fact, the reason DDR4 took so long to enter the market was incompatibility with existing hardware, and higher costs to upgrade. [1] I didn't go out of my way to buy "legacy hardware" because they weren't, at the time.

Point being, PC-building makes it easier to replace and repair individual components, but in time, upgrading to newer generations means spending over 50% of the original cost on motherboard, CPU, PSU, RAM. Not too different than dropping $3K on a new Mac.

It means the hardware was purchased after it started to be discontinued.

It's hardly a reasonable take, and makes little sense, to complain how you can't upgrade hardware that was already being discontinued before you bought it.

I googled for LGA1150 before I posted the message, and one of the first search results is a post on Linux tech tips dating way back to 2015 on whether LGA1150 was already dead.

And you purchased the Mobo one year after that.

I think you are forgetting the context of my replies. I'm not saying it's unreasonable to have to upgrade discontinued hardware, even if you have to do it all at once. My take is that it's not too different from having to replace a Mac when the new generation comes in (which is usually every ~5 years for Apple, not too far from my own system's lifetime). Being able to upgrade individual parts through generations is a pipe dream.

Also, we must have a different interpretation of "discontinued", because DDR3 and LGA1150 were still produced, sold, and dominated sales for way long after I bought that system. At the time (and for the next 1-2 years), consumer DDR4 was a luxury component that most no existing hardware supported.

You can still buy DDR3 new for not that much? 16GB is about $50 from numerous brands on Amazon at the moment. I bought some for an old laptop a couple months ago.

To do CPU upgrades you eventually have to replace the motherboard but you can keep using whatever your GPU/storage/other parts is. Sometimes that also means a RAM upgrade but it's still better than the literal nothing of modern Macs.

AMD has never disappointed me in this regard.

Zen 4 will being using a new socket, I wouldn’t go buying a Zen 3 with plans to upgrade the CPU down the road.

Well, you should still get one last upgrade out of an AM4 socket in the form of the upcoming 5800X3D ( https://www.amd.com/en/products/cpu/amd-ryzen-7-5800x3d )

This is already known for a long time already. You would have to actively choose to not listen to AMD news to not know.

I understand just making sure no one jumps on Zen 3 now with a promise of forwards compatibility.

8 years isn't a bad run for a CPU socket.
