How much memory did a 486 have?
The 486 was a 32-bit CPU with thirty-two 32-bit registers and 1.1M to 1.2M transistors in a 168- or 169-pin PGA package. Real Mode performed as an 8086 CPU that addressed 1MB of RAM, while Protected Mode addressed 4GB of physical RAM and 64TB of virtual memory.
What is a 486 computer?
A computer processor developed by Intel as an upgrade to the 386 processor series and commonly referred to as the 486 or i486. The 80486 has 8 k of memory cache built into the processor with 32-bit data bus architecture and was available in clock rates ranging from 20 MHz to 33 MHz.
How much RAM did a 386 have?
The 80386 featured three operating modes: real mode, protected mode and virtual mode. The protected mode, which debuted in the 286, was extended to allow the 386 to address up to 4 GB of memory. With the addition of segmented addressing system, it can expand up to 64 terabytes of virtual memory.
What type of RAM is fastest?
DDR4
Each generation of RAM improves on the previous one, bringing faster speeds and more bandwidth to the table. The fastest RAM in the context of home computing is easily DDR4.
What came after 486?
The follow-up for the 486 was the Pentium, at least in Intel’s case. But several companies made 486 CPUs, and several of those released their own follow-ups to the 486, including AMD and Cyrix.
How fast is 386?
The Deskpro 386 running at up to 16 megahertz (a measure of processing speed) is more than four times faster than a PC XT running at 4.77 megahertz because the 80386 chip digests data and software instructions in bigger chunks than either the 8088 chip of the PC XT or the 80286 chip of the PC AT running at 6 or 8 …
How much RAM did 90s computer have?

Is 3,200MHz good for gaming?
DDR4 memory really is maturing nicely. Just a couple of years ago, a decent DDR4-3200 kit was regarded as high-end, but as time ticks on, 3,200MHz is now the baseline for a decent gaming system.
When did the Intel 486 come out?
The 80486, also i486 and 486, (pronounced eighty-four-eighty-six) was a family of 32-bit 4th-generation x86 microprocessors introduced by Intel in 1989 as a successor to the 80386.
How many transistors did the Intel 486 have?
1989: 486 and i860 The 1,000 nm and 800 nm design was launched as the 486DX with 25 to 50 MHz, included 1.2 million transistors and delivered 41 MIPS.
What came after Intel 486?
How much RAM was normal in 2005?
It was generally DDR2 PC2100, PC2700, PC3200 etc and ran at 400 mhz from what I remember and generally you didn’t bother with more than 2 GB because that was Windows XP’s limit. Over PC3200 you increased speed 533 mhz, 667, etc up to 1066. I think 800 mhz was the top on 2005 but I may be off a bit.
How much memory does a 486 processor have?
The 80486has 8 k of memory cache built into the processor with 32-bitdata bus architecture and was available in clock rates ranging from 20 MHz to 33 MHz. The 486 was available as either a DX or SX, the DX features a built-in coprocessor, the SX does not. A 486 SX2 was also available and was capable of doubling the speed.
What does 486 stand for?
A computer processor developed by Intel as an upgrade to the 386 processor series and commonly referred to as the 486 or i486.
What is the difference between a 486 SX and 486 DX?
The 486 was available as either a DX or SX, the DX features a built-in coprocessor, the SX does not. A 486 SX2 was also available and was capable of doubling the speed. The picture is an example of the Intel i486 SX processor with the OverDrive socket.
What is the i486 processor?
The i486 was introduced in 1989 and was the first tightly pipelined x86 design as well as the first x86 chip to use more than a million transistors, due to a large on-chip cache and an integrated floating-point unit. It represents a fourth generation of binary compatible CPUs since the original 8086 of 1978.
