Happy birthday to the Intel Pentium CPU. 

The first Pentium CPUs were shipped on March 22 1993  These were 60 and 66 MHz CPUs that had a bus speed of 60 and 66 MHz respectively.  These first CPUs were manufacturing using a 0.8 µm process.

By January 1999 the CPU speeds were up to 300 MHz and the process had shrunk to 0.25 µm.

I remember making the leap from 486 to a 66 MHz "coffee pot warmer," so called because the 5V CPU generated a LOT of heat.  I don't remember the performance improvement being all that impressive but it made a huge difference nonetheless.  A year later I'd moved on to a 90 MHz Pentium which ran on 3.3V and was therefore a lot cooler (I've still got both systems packed away somewhere ... last time I ran the P90 it had NT4 on it).

Anyone else remember making the leap from the 486 to a Pentium?

  • yes. happy belated birthday inhell, oops intel pentium cpu!! ;-)

    the last 486 I had was a 486dx2 100mhz computer. gave it to a girlfriend's 2 kids to use for their school homework when I upgraded to a p133. not sure what they did with it after but I always say when I give old computers away, "if it's still working and you have no use for it, than pass it forward." ;-)

    • Cute

      The last one was the best - and oh so fitting. ;)

    I went from a 486-50 (straight 50, no clock doubling) to the Pentium Pro 200. That was quite a significant boost in performance.

  • My first ever PC was a P90...

    Eventually, I upgraded the CPU to a P120, but that machine is still working to this day. Of course, it's now running Linux instead of Win95A :-).

  • I still have several 496-DX66's around.

    All set up as Linux Router Firewalls. Have a couple of 133Mhz as well. Same deal. My move from a 486 was to an AMD K6-2 266MHz CPU and I have been an AMD user since then. I know, I know this is an Intel tribute... and I did start with an Intel 486-DX66... but when it was time to move up, I went with AMD because of price. ]:)

  • I must be getting old :-)

    The first PC I owned was a 4.77Mhz PC Jr. I put a NEC processor in it whichmade it perform like it had a 5.1Mhz processor.

    Since then:
    20 Mhz 386
    66 Mhz 486
    166Mhz Pentium
    1.8Ghz Pentium 4
    and... as of last weekend:
    Core 2 Duo 6400 (2x2.13Ghz)**

    The really big performance improvements have been from the Pc Jr. to the 386 and from the Pentium 4 to the Core 2 Duo.


    ** I swore I would go Linux or OS/X and never buy Vista but now here I am an early adopter. What am I nuts?

  • I remember ...

    when LOTS of peeps thought their precious 486 workhorses were not going to be displaced by the Pentium upstarts. Then they tried one.

    End of story.

    • Sadly Enough, I have thoughts on Vista

      I don't want to try it, but in the end, I will probably submit.

      Although, Mac and SLED are looking pretty amazing. Too bad Leopard is re-working the system just for Vista. Tsk tsk, they should have done that while Vista was in beta.

      • Same here

        I've always had mixed feelings about MS and Windows, but in the end I still keep truckin' down the MS way. Been on this road for so long it's hard just to jump off and start fresh elsewhere. Plus there is no getting around the fact that there is undeniable value in the Windows eco-system, broad as it is. It remains far from perfect of course, but then so is everything else mortal based.

        I am encouraged that Microsoft is making the kinds of inroads we now see with their heightened security standards. Long time coming, but the days of "swiss cheese for all" may finally be behind us. Let's also be glad there is solid competition with Apple and Linux, if nothing else to keep Redmond in check. I'd hate to think where we'd be without Windows, but equally so without the Mac and the Distros as go-to alternatives.

  • My first P class

    I actually went from my old Apple II+ to a P166 (though I did augment my II+ with a Tandy 100 ;).

    One of these years I'll break the 1 ghz barrier!

  • I started waaaay back...

    TRS80 16Kb
    TRS80 64Kb
    Amstrad 464
    Commodore 64
    Yamaha CX-5M MSX
    Amiga 1000 with Sidecar (XT PC with 20Mb HDD)
    Amiga 1000 with Phoenix board
    Amiga 2000 with G-Force accellerator and 2x52Mb SCSI HDDs
    486 DX4 100
    Pentium 100
    Pentium 133
    Pentium 166
    Pentium 200 MMX
    Pentium 233 MMX
    Pentium II 350
    Pentium II 400
    AMD 1800Mhz
    Pentium 4 3Ghz HT
    Pentium Core 2 Duo E6600 - Current

    A have been "in the industry" since the first Pentiums, hence, I have been able to upgrade regularly. The most noticeable speed increase I can remember was from the standard Amiga 2000 (6800) to the accelerated (68040) with the extra 2Mb RAM.

    The real WOW is in modem speeds. I started with a 300baud modem and remember watching the caharcters slowly fill each line on the screen (just like in the movies - although mine never made that movie sound effect). The progress there was:
    300
    1200/75
    2400
    4800
    14400
    28800
    56000
    1536000
    Now looking at ADSL 2+ at 20Mbits

    I noticed a difference EVERY time I upgraded there!
