Was the AMD 386DX40 actually that faster then the Intel equivalent or just an exotic alternative? At those ancient times I didn't even know AMD 386s existed 🤣... My 386SX 16/20Mhz soldered onboard my first computer (that sadly I'll never be able to find not having one only detail about the brand...) was Intel obviously.

Intel never made a 386DX-40MHz cpu. They had a 386SX-40Mhz, but i don't think any were made for socket use (anyone?)
The AMD 386DX-40MHz could keep up with an intel 486sx-25MHz in somethings, and was A LOT cheaper, and was faster than Intel's 386DX-33MHz. I think a lot of board manufacturers churned out a ton of soldered-on AMD 386DX-40MHz boards.

Regarding SCSI vs IDE, I had similar fears that on a slow system, the CPU overhead would benefit SCSI systems, so I benched a couple of hard drives on the slowest system that I have:
OS = DOS 6.22
CPU = approximating an 8088 @ 3.33 MHz (K6III+ downclocked on a special Socket 7 system slower than an IBM XT).
SCSI HD = 73GB Seagate SCSI Ultra320, 10000 RPM, Adaptec Ultra160 controller.
EIDE HD = 20GB Seagate EIDE, 7200 RPM, on-board controller.
Speedsys results for SCSI:
Speedsys results for EIDE:
There are certain instances were one HD is better that the other in those results, but when I tested a game (Striker, DOS game from '80s) to be loaded using the the downclocked slow CPU, they were both similar in terms of seconds loading - around 5 seconds or so. In the end, I'm not going to waste a PCI slot for a SCSI controller to see next to no benefit...
"Specially slowed down machine"? Does not prove anything. SCSI is still the best. 😈
It shows that at XT speeds, the CPU overhead should be exacerbated in favour of SCSI, especially with the hard disk/ controller combination used in my tests (more advanced on paper compared to the EIDE conterparts used), but it didn't. The EIDE setup was more than a match.
If it makes you happy, carry on with your 'best' mantra. Posting emoticons and absolutes is not helping your argument. For my needs, it's a waste of a PCI slot. And FWIW, my first ever PC builds all had SCSI, so it has its uses, but not for all cases.
Some people actually come here for serious discussion (not for unfunny 🤣). It's easy to hide behind forums, and pick and choose when you're 'joking', and when you're 'not joking'. So yeah, no argument then. Carry on, nothing to see.
I remember using the built-in EIDE port on my 486 in the mid-90's for web browsing and office tasks. I didn't think anything of HDD speed until I put in a SCSI controller. I recall the speed benefit feeling similar to when I upgraded from 8 MB of RAM to 32 MB. It was quite dramatic.
Will an (or any?) Intel 386 DX33 run well at 40 MHz? If so, how do they compare to the AMD DX40?
Plan your life wisely, you'll be dead before you know it.

If my one of the first posts below sounds like "not joking" to you, yeah, no argument then. Carry on, nothing to see. 🤣

Plus SCSI drives are heavier and make more noise which makes them "manly".
Plus the word "SCSI" sounds much nice to ears of anybody. You hear? "eideee": lame, "scuzzy" : cool!
Who cares a bout "real life examples"? What the f. is "real life", anyway?.. 🤣
