I started with AMD unitll Atlhon K6 (desktop) and Intel (laptop). After that only Intel (and Nvidia where I need dedicated GPU).
intel 386sx-20, AMD 486 DX-80, Cyrix P166+, AMD K6-2 500, AMD Athlon XP2000+, AMD Athlon 64 3700+, Core2 6600, i7-3770, A10-7850K , Ryzen 2600 upgraded later to 5700X
The A10 and the 2600 were mostly used as second computer, but with the upgrade it replaced the i7-3770
Graphics cards Trident 9000, S3 Trio+, Diamond Monster 3d (3dFX 1st gen), Nvidia TNT2, Nvidia GF2, GF5500, GF6200 ( bought for TV-OUT), GF7800, AMD 5770, AMD 7850 , NV 4060.
Well, if we start from the beginning, then:
- CP/M (school) with Unix datacenter;
- Motorola 6510 (with the Commodore 64, obviously)
- First PC XT with 8086, designed and assembled entirely by me (school assignment, very demanding assignment).
- i286 with Multitasking DOS (maybe MSDOS 4.0, very complex)
- i386DX with 387 math coprocessor and Windows 3.0
- in the middle, UNISYS terminals with xenix SCO.
- i486DX2 (the one with the first integrated coprocessor) and Windows 3.11. WITH THE FIRST 10 MByte HARD DRIVE.
- Windows 95 and Delphi arrive, also with an i486DX2.
- After a few years, I switched to AMD (I honestly don't remember the name of the first AMD processor I used) because it was cheaper.
- I continued with various AMD processors up to the AMD Athlon K6, also using Intel Pentium 4s in the meantime.
- From then on, I only used Intel for both laptops and desktops.
Like video cards, from Hercules, EGA, S3 TRIO, 3DFX Voodoo, and some other Nvidia cards.
