Raspberry Pi 4 is not going to be 5 times slower than your 10 year old laptop, unless it was really specced out. IIRC, RPi 4 is about as fast as Core 2 Duo.

Funnily enough, a C2D T9600 (midrange mobile dual core at the time) is 5 times slower than a Core i7-3610qm (10 years old, entry level mobile quad core) :D

  Intel performance jumps were crazy back then. You could expect +50% improvement between generations but you also gotta remember process manufacturing was moving fast back then too. 90nm to 65nm to 45nm within a few years.

It’s not that crazy, i7-3770K @ 153.48 GFLOPs vs Broadcom BCM2711 @ 13.5 GFLOPS. You can get various benchmarks to favor one over the other, but it’s still a large gap.

  That era of I3-i7 was 20-150 Gflops. Given the Pi is a low-cost device, it's not terrible unreasonable to at least compare it to the 20-50 Gflop CPUs of that period. But it's also not exactly fair as the HW Decode for video really makes them feel significantly faster in most process intensive workloads for general consumers, and USB3/eMMC/Micro SD cards are significantly faster than the IO used on iX-2000 to iX-4000 era computers (and later). The Pi4 is almost modern desktop capable for office/admin work. You're at about 25% CPU utilization using HW accelerated 1080p video on a Pi4. Still a little slow, but desktop software and most web apps run as well on a 4gb or 8gb Pi4 as they do on a low-end PC.

      I was looking at this: https://www.intel.com/content/dam/support/us/en/documents/processors/APP-for-Intel-Core-Processors.pdf https://www.intel.com/content/dam/support/us/en/documents/pr... Kinda just went with the bottom half of the 2010-2014 era chips.

        That list isn’t limited to actual laptop/desktop chips. If it ends in E it’s an embedded chip for stuff like smart refrigerators etc. LE/LM are for even lower power devices. I would suggest looking at actual cheap laptops from 2012 if you want to see what the low end actually looked like.

        A lot of the sub 50 GFLOP stuff were low-end Laptop chips with regular M-suffixes. These are mobile Ivybridge chips, they were not snappy, and as late as 2013 release dates for sub 50 GFLOPs.

Todau I have to run 5 electron apps in the background before I can even start working, PI simply cannot handle even my basic day to day tasks.

10 years ago was 2012. You got your years wrong. Core 2 Duo was 2006. You'd probably be thinking about 16 years ago.
