IBM PC/XT compatible personal computer
(1984)
My first PC/XT was based on 8088 Intel microprocessor, 16 bit ALU with 8 bit data bus (7.5MHz)
1 MByte RAM and four 360 KByte floppy disks - two monitors: Hercules & CGA
During past 30 years I had to replace processors and other components continuously:
- (1984) Intel 8088
7,5 MHz; FPU ext; ALU 16 bit; 29 000
transistors; 3,0 µm
- RAM 1 MByte - FDD 360 KByte - CGA 320×200 16 colors ISA-8.
- (1992) Intel 80286
16 MHz; FPU ext; ALU 16 bit; 134 000
transistors; 1,5 µm
- RAM 4 MByte - HDD 20 MByte - EGA 640×480 64 colors ISA-8.
- (1994) AMD 80386DX
40 MHz; FPU ext; ALU 32 bit; 275 000
transistors; 1,0 µm
- RAM 16 MByte - HDD 200 MByte - SVGA 1024×768 256 colors ISA-16 256 KByte - Internet 16 Kbps.
- (1996) Intel 80486DX4
100 MHz; FPU int; ALU 32 bit; 1 600 000
transistors; 0,6 µm
- RAM 32 MByte - HDD 1 GByte - XGA2 1024×768 1 mln colors PCI 1 MByte - Internet 64 Kbps.
- (1998) Celeron Mendocino 333 MHz; FPU int; ALU 32 bit; 19 000 000 transistors; 0,25 µm; FSB 66 MHz; L2 cache 128 KByte
- RAM 128 MByte - HDD 30 GByte - SXGA 1280×1024 16 mln colors AGP2 32 MByte - Internet 115 Kbps.
- (2001) Celeron Tualatin 1200 MHz; FPU int; ALU 32 bit; 28 100 000 transistors; 0,13 µm; FSB 100 MHz; L2 cache 256 KByte
- RAM 512 MByte - HDD 210 GByte - SXGA 1280×1024 16 mln colors AGP4 128 MByte - Internet 1 Mbps.
- (2008) Intel P4 Prescott
3000 MHz; FPU int; ALU 64 bit; 125 000 000 transistors; 90 nm; FSB 400 MHz; L2 cache 1 MByte
- RAM 2048 MByte - HDD 1024 GByte - SXGA 1680×1050 16 mln colors PCI Express x16 512 MByte - Internet 2 Mbps.
- (2009) Dual-Core Wolfdale
3000 MHz; FPU int; ALU 64 bit; 410 000 000 transistors; 45 nm; FSB 1300 MHz; L2 cache 6 MByte
- RAM 4096 MByte - HDD 3×1024 GByte - SXGA 1680×1050 16 mln colors PCI Express x16 512 MByte - Internet 25 Mbps.
- (2012) Dual-Core Wolfdale
3000 MHz; FPU int; ALU 64 bit; 410 000 000 transistors; 45 nm; FSB 1300 MHz; L2 cache 6 MByte
- RAM 4096 MByte - HDD 4×1024 GByte - SXGA 1680×1050 16 mln colors PCI Express x16 2048 MByte - Internet 25 Mbps
(2012)
Today I use computer with 64 bit processor and it's clock is 400 times faster,
RAM is 3000 times larger and hard disc capacity is 3 millions times higher,
and the number of colors on the screen is one million times higher.
What will I use after next 10 years?
