alt Hacker NewsThe Megahertz Wars were an exciting time. Going from 75 MHz to 200 MHz meant that everything (CPU limited) ran 2x as fast (or better with architectural improvements).
Nothing since has packed nearly the impact with the exception of going from spinning disks to SSDs.

"Bananas" core-counts gave me the same experience. Some year ago I moved to Ryzen Threadripper and experienced similar "Wow, compiling this project is now 4x faster" or "processing this TBs of data is now 8x faster", but of course it's very specific to specific workloads where concurrency and parallism is thought of from the ground up, not a general 2x speed up in everything.

About a week ago, completely out of the blue, YouTube recommended this old gem to me: https://www.youtube.com/watch?v=z0jQZxH7NgM
A Pentium 4, overclocked to 5GHz with liquid nitrogen cooling.
Watching this was such an amazing throwback. I remember clearly the last time I saw it, which was when an excited friend showed it to me on a PC at our schools library. A year or so before YouTube even existed.
By 2005, my Pentium 4 Prescott at home had some 3.6GHz without overclocking, 4GHz models for the consumer market were already announced (but plagued by delays), but surely 10GHz was "just a few more years away".
When Alder Lake finally made a sizable jump, I looked at decades of old tests I'd done along the way with CPUs and tried to bridge them together reasonably.
Between IPC (~50 to 100-fold improvement) and clock speed increases (1000-fold alone), I estimated that single-thread performance has increased on the order of 50,000x - 100,000x since the 4.77 MHz 8088.
In human terms this is like one minute compared to one month!
I still remember my first CPU with a heatsink. It seemed like a temporary dumb hack.
SSDs were such a revolution though, and a really rewarding upgrade. I'd fit SSDs to friend and family computers as an upgrade.
I think the single biggest jump I ever experienced was my first dedicated GPU — a GeForce 2 MX if I'm not mistaken.
Agreed. That was the next big boost! I installed my first SSD in this HP workstation-grade laptop that we got "for free" from college. It was like getting a brand new computer! In fact, I ended up giving that computer to my sister who ran it into the ground.
I didn't feel any huge speed boosts like that until the M1 MacBook in 2020.
GPUs for 3d graphics were a game changer.
I can see why you wouldn’t consider it as impactful if you weren’t into gaming at the time.
My first pentium was clocked at 60Mhz.
I remember our school getting new computers to replace the 233Mhz G3 iMac computer lab during the Megahertz Wars and the vice principal announcing the purchase of new "screaming fast" 600 Mhz Dell Optiplex GX100. The nice thing is that the G3 iMacs then got pushed out to the classrooms, but it was sad to see Apple lose the spot in the lab. I miss the wonder of playing Pangea Software games for the first time like Bugdom and Nanosaur.
That wasn't how it worked.
Up until the 486, the clock speed and bus speed were basically the same and topped out at about 33MHz (IIRC). The 486 started the thing of making the CPU speed a multiple of the bus speed eg 486dx2/66 (33MHz CPU, 66MHz bus), 486dx4/100 (25MHz CPU, 100MHz bus). And that's continued to this day (kind of).
But the point is the CPU became a lot faster than the IO speed, including memory. So these "overdrive" CPUs were faster but not 2-4x faster.
Also, in terms of impact, yeah there was a massive incrase in performance through the 1990s but let's not forget the first consumer GPUs, namely 3dfx Voodoo and later NVidia and ATI. Oh, Matrox Millenium anyone?
It's actually kind of wild that NVidia is now a trillion dollar company. It listed in 1998 for $12/share and adjusted for splits, Google is telling me it's ~3700x now.
I don't know. I felt this way when switching from Intel laptop to Apple M1. I am still using it today and I prefer it over desktop PC.
In my experience, SSDs had a bigger impact. Thanks to Wirth's Law (https://en.wikipedia.org/wiki/Wirth%27s_law) the steady across-the-board increase in processing power didn't equate to programs running much faster, e.g. Discord running on a modern computer isn't any more responsive, if not less responsive than an ICQ client was running on a computer 25 years ago.
SSDs provided a huge bump in performance to each individual computer, but trickled their way into market saturation over a generation or two of computers, so you'd be effectively running the same software but in a much more responsive environment.
