| Processor Types Intel and X86 vs Motorola, Digital, … | |
| Capabilities Vary with Microprocessor and Chipset | |
| Chipset are support chips on the Motherboard | |
| Buses, paths for data affect the I/O speed. | |
| Early chips had Math Coprocessor for math processing. | |
8086/8088 PC/XT or 8088 Family
| Introduced June 1979 | |
| 8088 needed 8087 Math Coprocessor | |
| 1 Meg memory max | |
| 16 bit int. reg., 8 bit data I/O, 20 bit memory | |
| 8086 8087 16/16 Bit Processor | |
| Also Made a few V20 Chips | |
| All 5 volts |
| Introduced Feb 1982 | |
| 286 and Real and Protected Mode, increased speed,..... | |
| True 16 bit processing and bus | |
| 16 Meg RAM max | |
| All 5 volts |
| 386 DX True 32 bit Introduced Oct 1985 | ||
| (internal registers, data and external data buses ) | ||
| 275,000 transistors in a VLSI circuit.. | ||
| Addresses 4 G of physical memory. | ||
| 3 modes, Real, protected, and virtual. | ||
| SX's for economy June 88 | ||
| 32 bit internal register, data 16 bit | ||
| 16 Meg memory maximum. | ||
| 486DX April 1989 includes math co-processor | |
| Moved cache controller and cache memory into the chip | |
| 8K internal cache. | |
| 32bit internal register, external data bus, and address bus. | |
| Same dimensions as 386DX, | |
| But 1.2 million transistors size of your thumbnail. | |
| Can address 4Gig RAM and manage 64T, like the 386DX. |
| Pentium 60 March 93, to 4 Gig RAM | |
| Pentium-MMX Built in FPU Jan 97 | |
| Pentium Pro Built in FPU Nov 95 64Gig | |
| Pentium II Built in FPU 64 Gig | |
| Pentium III Built in FPU | |
| Pentium IV |
| Single Edge Contact | ||
| S.EC. Cartridge Design | ||
| Includes dedicated 512KB L2 cache | ||
| Includes 32 KB of L1 cache | ||
| 2X that of P.Pro | ||
| Error Correction Code Available | ||
| Uses the SECC2 (Single Edge Cartridge Contact 2) package style | |
| Improves heat conduction from the processor core | |
| Allowing it to remain cool | |
| And achieve consistently stable operation. |
