Memory in particular is something that I've reflected on more than once as having the most impressive gains in computing since I started paying attention to it (networking/USB too, but that doesn't make your computer "faster" in the same way).
I remember being able to borrow a computer from somewhere when Diablo II had just come out in 2000 which had a 450Mhz Pentium III and 64 MB of RAM. 64MB of RAM was probably mid-tier at the time, i.e. very much not a given. As I recall Diablo II recommended 64MB for single player and 128MB for multiplayer (or above 4 players or something).
The computer I'm writing this on has 64 GB of RAM, 1024 times as much. By comparison I have a 20-core Intel CPU with up-to 3GHz speed or somewhere around there, even pretending each core could run at that max speed simultaneously (which they can't), that's only 133-times as much CPU power.
Maybe the NVMe read times are as/more significant than memory size increase, but the metrics on them isn't quite as front and center on PC specs as memory and CPU.
Hard drive capacity similarly impressive as RAM in terms of size (was apparently 10-30GB in 2000), but I don't have a 10TB hard disk as I don't need one that big (1TB is plenty for me), so again it's not as impactful to me as memory.

Over that time CPUs have also increased their instructions per clock by 3 to 4 times, so the comparison is a bit closer than that. 5Ghz in CPUs is also common these days which would make it even closer. RAM has also improved in more than just total size though.
I completely agree. With everything from Out-Of-Order execution, deep pipelines, SIMD, huge CPU cache, etc... I would be surprised if the performance increase is not considerably more than 1024x.
GPUs are even more extreme. A 5060 is something like 15,000x faster than a 3dfx Voodoo card from ~2000 by my limited research.

This nerd sniped me a bit. Your calculation on the amount of CPU power is too low, because of the change in IPC, but for the things we have benchmarks for, it isn't multiple orders of magnitude off like I expected. Looking at Cinebench 2003, prime95, and a few other benches, I get somewhere between 300x and 850x faster for the modern CPU over the Pentium 3.
For me, the biggest change in performance in my life was going from spinning disks to SSDs. That change felt bigger than any other leap by a long shot.

This was the most impactful upgrade/breakthrough for me. The first time I put even a SATA SSD in my PC at home I was completely blown away. It still blows my mind somewhat the amount of compute I have sitting on my desk though, both in terms of memory and CPU/GPU power, but that move from spinning rust to solid state was huge.
Then Apple did to me again with the M1 launch and NVMe speeds that made swapping nearly imperceptible.
Me too. I distinctly remember saying that I would never own a non-solid state boot drive again.
The funny part is that a 1000x increase in RAM somehow doesn't make a modern computer feel 1000x more luxurious
When was the last time you used a vintage computer? I couldn't believe how long people had to wait for the start-up (and shutdown) processes; and there was no hibernation! (Windows 9x/System 7.x). Modern instant-on functionality is 1,000,000 times better than that
that's only 133-times as much CPU power
akshually, it's also more closer to 500-1,000x. You can't look at clock speed only. Processor architecture makes all the difference. Pipelining, SIMD, memory bandwidth, blablala, everything got way better. Better approximation would be to use something like a synthetic benchmark or just (theoretical) FLOPS of each.
Otherwise, we can say that 6502 at 15Ghz is better than what you have now: https://news.ycombinator.com/item?id=22859706
