How fast was a 386 computer?
Compaq introduces the Deskpro 386 system At 4 million operations per second and 4 kilobytes of memory, the 80386 gave PCs as much speed and power as older mainframes and minicomputers.
What is the difference between SX and DX in a 386 chip?
ARCHIVED: What are the differences between the 386SX and DX Intel processors? Memory access is faster with the DX Intel processor. The SX takes two fetches to get a piece of memory, whereas the DX takes only one fetch. Also, the SX is limited to 16MB of addressable memory, while the DX may have as much as 4GB.

What’s clock speed?
The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz). A CPU with a clock speed of 3.2 GHz executes 3.2 billion cycles per second. (Older CPUs had speeds measured in megahertz, or millions of cycles per second.)

How many registers are there in an x86 processor?
Guide to Using Assembly in Visual Studio — a tutorial on building and debugging assembly code in Visual Studio Modern (i.e 386 and beyond) x86 processors have eight 32-bit general purpose registers, as depicted in Figure 1. The register names are mostly historical.
How are memory addresses determined in the x86?
In addition to supporting referring to memory regions by labels (i.e. constant values), the x86 provides a flexible scheme for computing and referring to memory addresses: up to two of the 32-bit registers and a 32-bit signed constant can be added together to compute a memory address.
