Alan Woodward, cyber security professor at Surrey University, said the "Chinese influence that might be behind the decision," he said, adding E2EE is "largely banned in China".
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.
