How fast was a 386 computer?
4 million operations per second
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.
When did 386 computers come out?
1985
The Intel 386, originally released as 80386 and later renamed i386, is a 32-bit microprocessor introduced in 1985. The first versions had 275,000 transistors and were the CPU of many workstations and high-end personal computers of the time….i386.

What was a 386 computer?
The PC-386 was a 32-bit personal computer with a 20-MHz 80386 CPU that could run PC-98 series software at more than twice the speed of 16-bit machines. Featuring ample extensibility, the PC-386 offered high-speed processing of business applications along with excellent cost effectiveness.
When did the 286 computer come out?
February 1, 1982
The Intel 80286 (also marketed as the iAPX 286 and often called Intel 286) is a 16-bit microprocessor that was introduced on February 1, 1982.
How much did a 386 cost?
There was a large price gap between the 386 and 286 lines that the PC clone vendors were eager to fill, and the 386SX architecture fit the bill in spades. By golly, you could have one of these babies for as little as $1,945 — well into the 286 price range — or for as much as $6,495 for a “compact” unit.
How much gold is in a 386 processor?
The Pentium Pro also had two separate chips inside so this doubled the amount of solid gold wire bonding that is usually found in a single chip CPU like the Intel 386 and 486 chips. Gold refining yields of the Pentium Pro have been reported to be as high as around . 33 grams per CPU.
What were computers like in 1987?
IBM introduced the PS/2 personal computer with improved graphics, a 3.5-inch diskette drive, proprietary bus to help prevent clones, and a bidirectional 8-bit port. CompuServe introduced the GIF standard and images in 1987. Development of ImageMagick began in 1987. IBM introduced VGA in 1987.
Did they have computers in 1986?
Other computer events in 1986 IBM introduced the IBM 6150 or IBM RT (RISC Technology) computer. The computer used either the AIX, AOS, or Pick operating system. More than 30 million computers were in use in the United States. IMAP was developed by Mark Crispin at Stanford University in 1986.
What is the difference between SX and DX in a 386 chip?
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.
Are old processors worth anything?
These are CPUs that are from much older computers and generally are worth the most money. The ones that are worth more money will have gold on both sides, and these chips are generally the older style chips that were made in the 1980’s or 1990’s.
What electronic has the most gold?
Computer CPU’s (processors) have the most precious metal value by weight, followed by Memory (RAM) & Circuit Board Fingers / Connectors / Pins, then Circuit Boards (Motherboards), then cables / wires, with hard drives & whole computers being last.
What were computers like in 1985?
In 1985, it was the 68000 generation, the first 32-bit machines, that represented the hopes and dreams of the future. The 68000-based computers from Apple, Atari, and Commodore were fast enough to run in graphics mode all the time and use a mouse for interaction, not just a keyboard.
How many transistors are in a 386 microprocessor?
Introduction of Intel 386 (later qualified DX) processor with 275,000 transistors The Intel 80386, also known as the i386, or just 386, was a 32-bit microprocessor introduced by Intel in 1985. The first versions had 275,000 transistors and were used as the central processing unit (CPU) of many personal computers and workstations.
What is the Micro Channel architecture?
] Micro Channel architecture, or the Micro Channel bus, was a proprietary 16- or 32-bit parallel computer bus introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s. Its name is commonly abbreviated as “MCA”, although not by IBM.
What is a Micro Channel bus?
Micro Channel architecture From Wikipedia, the free encyclopedia Micro Channel architecture, or the Micro Channel bus, was a proprietary 16- or 32-bit parallel computer bus introduced by IBM in 1987 which was used on PS/2 and other computers until the mid-1990s. Its name is commonly abbreviated as “MCA”, although not by IBM.
What is the MIPS of an 80386 microcontroller?
A 33 MHz 80386 was reportedly measured to operate at about 11.4 MIPS. The 80386 was launched in October 1985, and full-function chips were first delivered in 1986. [vague] Mainboards for 80386-based computer systems were at first expensive to buy, but prices were rationalized upon the 80386’s mainstream adoption.
