SBC486DX66 processor module is a processor based on Intel 486 architecture, the following is a detailed introduction to it:
Core architecture: Based on Intel’s 486 DX architecture, which has a high reputation and wide application in the computer market at that time.
frequency
Main frequency: 66MHz, achieved by doubling the bus frequency (33MHz), this design makes the processor more efficient in processing data and executing instructions.
Bus frequency: 33MHz, which is the frequency at which data is transferred between the processor and other components.

Digital coprocessor: “DX” means that it has a digital coprocessor function and can directly handle floating-point operations, improving the speed and accuracy of mathematical operations.
Cache: Although the specific cache size is not explicitly mentioned in the product information, based on the common specifications of the 486 DX processor, it is speculated that it may be equipped with 8KB L1 cache, the presence of a cache to further improve the speed and efficiency of data access.
Interface: Possible use of the Socket 2 interface, which was a more advanced design at the time, to provide better stability and compatibility.
Heat dissipation design: Since the heat problem of the CPU in the 486 era has not become a serious problem, the heat dissipation design of the processor module is relatively simple, such as only using a small heat sink for heat dissipation.

Performance and application
Personal computer field: As the core processor of personal computers, it can meet the needs of users in multitasking, graphics rendering, text editing and other daily applications, and the 66MHz main frequency and possible 8KB L1 cache provide users with a smooth operation experience.
Office and business fields: SBC486DX66 can efficiently handle a variety of office software, database systems, spreadsheets, etc., supporting complex document editing, data processing and report generation, helping to improve work efficiency.
Multimedia entertainment field: With excellent floating point computing ability and digital coprocessor function, it is widely used in multimedia entertainment field, and can support early 3D games, audio processing software, video editing software, etc., to bring users a rich entertainment experience.
