My first computer was a Intel 486DX-33 / 4MB RAM / Trident 8900C. That display card could only handle up to 800 x 600 with 256 colors, viewing photos back then really sucked. And it was so slow every time I moved a window in Windows 3.1, I had to wait for it to be repainted.
Sometime later a revolutionary technology arrived (for PC anyway) : 16-bit colors! That Cirrus Logic card could show 65000 colors. Along with JPEG, now photos looked MUCH better.
A little while later, VL-Bus and “Windows accelerator” arrived. Now with the Tseng Lab ET4000 W32, windows were painted almost instantly.
This is a major reason why AMD Ryzen has been taking a lot of mindshare away from Intel (at least outside of the gaming community).
