The disadvantage of the Am386 versus the 486 was that the 386 bus was an evolutionary dead end. The 386 topped out at 40 MHz,with the only upgrade path being one of TI and Cyrix’s clock-multiplied 386/486 mashups. Meanwhile, the 486 reached speeds of 133 MHz by September 1995. But since most 40 MHz 386-based PCs were open architecture clones built from off-the-shelf AT parts, you could swap the motherboard and CPU while carrying over most of the rest of your parts. This was more expensive and labor intensive than swapping a CPU, but it was much cheaper to buy a 40 MHz 386 and upgrade to a faster 486 after 2-3 years than it was to buy the fastest 486 at the start.

The ArmSoM AIM7 packs an RK3588 with 8GB of LPDDR4X into a Jetson Nano-compatible form factor. Geekbench scores of 828 SC / 3,186 MC. I covered this one in depth in my full AIM7 review and the summary hasn’t changed: if you specifically need a Jetson Nano replacement with modern performance, the AIM7 does exactly what it says on the tin. If you don’t need that form factor compatibility, there are more flexible RK3588 options out there for less money. As mentioned earlier, ArmSoM continue to impress on the documentation and overall quality front though.
