Athlon XP 1700+ was my first self-built machine. First bought computer had a Intel Celery 500mhz with 64mb RAM.

Was a classy 486 sx 33, think it was amd but it was a long time ago

Pretty sure the first CPU I bought on its own was a Duron 1600, to upgrade the Duron 1200 that my first PC came with…

XP2800 in the first desktop I built.

First CPU within a PC: 486 DX2 66

First CPU on its own: AMD Athlon 3200

Going by the more modern CPU format then my first came with a pre-built as I was only about 13 at the time and hadn't delved into building at that point, BUT it was an Intel P166 that came with an awful Packard Bell Win95 PC.

The first ever chip I used in any device however was the one inside the commodore c64 ;)

oops they don't count! My first stand alone cpu part was an AMD Athlon x2 (prior CPU's came in bundles)

O wow, thats about 20yrs ago. I seam to recall AMD386 or AMD's 386 equivalent can't remember any more than that.

I see a lot of AMDs here :) Hopefully Ryzens are selling as well, because really they are the Athlon XPs of these days.
My first CPU was a Athlon XP 2000+ ~1.67Ghz which overclocked to over 1.8Ghz. Very nice CPU indeed.

First separate 32-bit CPU was a Pentium MMX at 133MHz (I think?).

I also upgraded a BBC Model B to a CMOS 65C02.

It depends on how you classify purchased, my the first cpu(s) I requested in a custom build (I basically said what I wanted) were 2x AMD MP1900+ cpu's but I didn't actually install them because I wanted some warranty on what was a very expensive machine at the time.

The first cpu I bought and built into a rig myself was an AMD Opteron 175 iirc, it actually replaced the rig above. Now I pretty much refuse to buy off the shelf pc's even though I hate how small and fiddly it is to install some parts of a pc these days.

First in a computer - 486 DX2-66

First as an install - Cyrix PR133+

Depends how you quantify separate -

First CPU (upgrade) - 50MHz 68030 with a 50MHz FPU and a whopping 8MB RAM on a Viper II accelerator card for my Amiga 1200.
First x86 CPU - 450MHz AMD K6-II for my first self build (alongside a Voodoo 3… :sigh: good times).

My first PC machine (from Dan) ran on a Pentium 120, but for my first self build PC I chose a Duron 900 (Morgan).

But previous to both those I bought an Viper 68030 trap door upgrade board for an Amiga 1200.

I was given a Pentium II 233, cartridge looking thing and an S3 Virge DX to get me started. The first CPU I actually bought for myself though was an AMD Duron 900. At the time I couldn't afford a fully fledged chip and settled on the Duron as gaming performance was better than the Celeron of the time.

AMD 386DX-40. The little trooper.

Mr_Jon
AMD 386DX-40. The little trooper.

A 486-DX 66. Between that and my current Haswell i5 everything in between was AMD.

Think it was the Pentium P5, along with fdiv bug

Joining the amiga upgrade club. Bought an Apollo 68020 accelerator board for my a1200.
Miss the amiga days.
First pc was a self build, bought an AMD k6 200. Cost something like £285. Have never spent close to that again.

Jinx
First in a computer - 486 DX2-66

First as an install - Cyrix PR133+

OMG, I remember having a couple of Cyrix machines at one point. Forgot all about them :)

This is a bit tricky. In a sense “my first CPU” was in my first PC. It was built to order (using Intel's brand-spanking-new “Plato” motherboard with PCI *and* a flashable BIOS), but I got to choose the CPU among other things. That CPU was the Pentium 90 MHz, of course including the famous FDIV bug. Which of course I got replaced due to Intel's very costly exchange program. That CPU went on to live in my first self-built PC, based around an ASUS P/I-P55T2P4 motherboard. But again, the CPU came as part of a pre-built system of sorts.

My first true CPU bought as a stand-alone part then has to be the Pentium II 350 MHz. Using the “future-proof” Slot1/SECC connector it was my pride and joy. The system it powered was based around an ASUS P2B-F motherboard (later replaced by an ASUS P3B-F I got for free). Yeah, that was back when ASUS were still doing high-quality motherboards, where “high-end” didn't mean blinking RGB lights and heat sinks with “go faster” stripes. Those were the days…

(The honour of being my first ever computer goes to the Texas Instruments TI-99/4A, followed by the Commodore 64 (what else), and the Amiga 500 and the Amiga 2000.)

First CPU I purchased on its own was a Celeron 400 mainly as it could happily be overclocked to 600Mhz. I think it cost me about £120 and replaced a Pentium II 300Mhz which had been running overclocked at 450Mhz. (sigh) Those were the days!

AMD K5 PR100 GOLD this was good time and lots of fun.
Regards,

First cpu I bought that wasn't in a pre-built was a AMD Athlon64 3400+ on socket 775 just after launch. Up until then I always had pre-built pc's but got fed up with paying a fortune for a pc with the cheapest components the shop could find in them and switched to self building.

First CPU in a system - 486 DX2 80 Cyrix

First CPU alone - AMD K6 (?) about 150mhz. Can't remember. Closely followed by Pentium II 300 overclocked to 450 by moving one jumper. That was a trooper - still being used I think!

“We are, of course, referring to standalone parts, so a CPU acquired as part of a system or laptop doesn't count.”, o.k. that removes 3 older contenders leaving my 1st CPU bought for my 1st solo system build: an AMD Athlon XP 2500+. Ah, I remember it fondly doing me proud for many years in my main PC then my secondary one.

cyrix 586? can't remember eventually saved up enough pocket money for a p60

Intel Core Duo E8400 (dual core @ 3.00 GHz)

i7 920 ‘cause I’m a youngin, thing lasted me 8 years!

An i5 2500k, which is still being used to this day, if you can believe.

Fuzzy memory here, but i'm fairly sure it was an early socket-A Athlon of some type.

(It was to replace a several years old pre-built 333mhz AMD K6-2 system i had for university)

First CPU for self build 1.4 Ghz Athlon Thunderbird

First CPU in a pre built PC was a 166 Mhz Intel in a Compaq Presario

First CPU brought as a component was a Core2Duo E8500. Was O/C'd to 3.8Ghz from day one and still runs to this day as a back up back up back up back up machine!

specc'ed the parents PII-350 (and added the Voodoo2 in myself).

first built for me was a Athlon 1000 Thunderbird with a DDR motherboard and the 266 chipset, and a Geforce 3.

First computer of my own was the classic AMD Athlon 1333 MHz, the good old Thunderbird days.

First computer I built from scratch used a Phenom II X4 955.

I haven't bought too many CPUs over the years though since I have generally been of the opinion that by the time the CPU needs replacing the motherboard needs replacing, and if you are replacing CPU, motherboard and often the RAM too you might as well get a whole new computer. So I always tend to build one base unit every 4-5 years, and have one or two GPU upgrades during its lifecycle.

AMD Duron 900, I believe.

K6-2 400! Fun story - me and my Dad had been rear-ended by some bellend. We'd stopped at a yellow, he went full-force into us. Fast forward whenever, my mam is like “pretend you're scared of cars” “eh?!” “just do it!” *cue me getting an Oscar*

Long story short we got compo, a few months after they released a portion of it to me and I used it to build my very first PC (first build, second PC, first was a Tiny P1-166 that my parents took 10 years to pay off, bless em). Lian Li case, 128mg RAM, 40gb HDD, dedicated voodoo card, and the aforementioned K6-2

An IBM 6x86MX PR200 (which was a rebadged Cyrix CPU) in 1999… It was ok, until I started overclocking it :p

K6-2 233 I think is the first stand alone CPU I ever bought. First CPU used was a Z80 in a Spectrum.

The legendary Celeron 300A.

First processor I ever bought would have been an 8087. This was a maths coprocessor that plugged in next to the 8086 CPU. After that it would have been an early 486 of some description. I missed the 2 & 386 out completely.

The first CPU on it's own was a 486SX-25 - the integrated Z80 in my Sinclair door wedge doesn't count.

It's been Trigger's Broom ever since.

A Dell 486SX-25, which I later upgraded to a DX4/100 overdrive which was the first CPU I purchased.

First home built PC was around a Pentium 233Mhz with MMX technology (ah yeh!)

My first standalone must be my S754 AMD Athlon 64 3000+. Bought as part of a build that was put together for one job alone - to play HL2. Was upgraded to a 3700+ a while later.

First CPU I had was a K6 350, but that came in a pre-built machine I had to start uni with (showing my age). That came with an SIS 6326 - not good for Counter-Strike!

I bought an Athlon 700 for a retro-gaming-parts cobble up a little while afterwards.

The first CPU I bought separately was an Athlon 64 3200+ on socket 939. It had quite a long life for LAN gaming up until relatively recently, playing old games like CoD/CoD2 on it, but unfortunately the motherboard starting getting issues, so it is now sitting in a cupboard.

intel 486 sx25, although I did have a 286 and 386 system before that

First CPU of any sort - MOS Technology 6502 (Late 1981, part of a kit-form Acorn Atom)

First x86 CPU in a system - Intel 486DX/2 66MHz

First x86 CPU as a component - Cyrix 6x86PR150+ (120MHz)

Oh, and the oldest bought-as-a-component CPU I still use on a semi-regular basis is an AMD K6-III 400. It joins my Voodoo3-3000 powers my Win98 legacy gaming box.

First stand alone was a Core2 e4300 (clocked it to 3.24ghz form 1.8ghz)

Basically had prebuilt pentium 2/3/4 machines before that.

Only 2 on from the e4300, with a q9550 then i5-3570k (Current) to make way for an R7-1700 in the not to distant future.

Z80 in my ZX81 with wobbly 16k ram pack.

1st PC with a 486sx20 (overclocked to 24mhz!)

1st self build, I think, was a Cyrix 133+, which was upgraded to a 166+ and then a K6 233.

First processor?

Hmmm … I think a Z80 (on a card) to allow me to run CP/M on my 6502-based Apple IIe which, IIRC, then allowed me to runa COBOL compiler.

Cyrix 100 mhz

My first pc's cpu was 386DX 33MHz first that I built from scratch was a Pentium 133

Zilog Z80B (as per my system specs)

Sad to say but i cannot actually remember, maybe a core duo or one of the last single core Pentiums or maybe it was an early Athlon.
Being an Engineer (as in hands on, actually make things) it was the making of a PC that attracted me to doing it when it became financially viable to do it rather than buying a pre built one.
The attraction has worn off a bit (though i would still build my own if i need a new one)as its not as challenging to do as i thought it would initially be. Basically its just self assembly and most folk could do it.
The recent AMD revival has peaked my interest again a bit.

Intel Celeron D @ 2.6Ghz

fairly sure it was an AMD k5, the most memorable PC i built was in 1999, with windows 2000 coming out. (i thought we would be getting loads of multi threaded program/games from then on) i bought a motherboard with room for 2 Pentium 2, SCSI controller. once windows 2000 was out i added the other CPU and was the quickest kid on the block for a year or 2 :P the best best memory from that PC was how well it would run music in the background, and a let me play a game without the music getting interrupted, the next PC i build couldn't do that.

Pentium II 333Mhz in ‘98.

Part of a £1500 pre build

8GB Hard Drive, 64Mb RAM, Windows 98, ATI Rage Pro (replaced with a 3DFX Orchid Righteous Voodoo II) & 15’ CRT monitor.

AMD Athlon, socket A. Not sure which model though…

Some Duron in an Asus A7A266 running a nvidia 2Ti.

Had several prebuilt pcs in the family home before that, can't remember what they were and we never did anything to the BBC Model B or Spectrum beyond running them as they came.

The first CPU I bought was an Intel MMX 166 back in 1997, which was part of my first custom build PC.

Pre-built: a Cyrix 6x86 running at a heady 166mhz
First self build - AMD duron 1200

I think i still have the duron in a box somewhere……:embarrassed:

A Pentium 3 @ 450MHz, compared to what I had been using at work it seemed to fly.

On it's own, that would have been a Celeron 300A. Bought me and my brother a pair of them and they went into two different boards: an Abit and an AOpen one. AFAIR, the AOpen was the better board as it was able to run of them at 460MHz or so while the Abit only managed 450MHz. With Slot 1 it was really to swap CPUs over as otherwise I'm sure I wouldn't have bothered trying to see if the board or the CPU was what wasn't able to hit the final 10MHz or so.

mine was a amd 486 and a cyrix m3 them a Athlon 300 amd thunderbird pencil mod Athlon 2400 mobile overclocked to a pr2800 then a Athlon64 then a Pentium m laptop house fire then a cheap amd a10 and now the hp omen I have now

My first CPU was a Cyrix chip that I bought at a computer show. After that, I bought a 486 SX 20 MHz processor. 0.0
Now I feel old thanks to Hexus. >.<

First CPU I ever purchased… hmmm… I'm guessing it was a K7 Thunderbird but I couldn't tell you what the model number was.

C300A
Saved for ages

Intel Pentium 4 3GHz HT. Cost me £100 back then!

i5 2500k. Good ole Sandy Bridge. I've still got it running in my multimedia rig.

3570k is my first bought because I always had laptops before, it's going to need replacing soon hopefully with a 8700k.

First in a PC 486 sx33 then upgraded it with a 486 DX2 66.

I really don't recall, It could've been a K6-2 400 or a Celeron Coppermine 633. I feel old…

Although I've been involved as kid with computers since the zx80, RML 380Z and BBC model A era, the first PC I bought for myself was an Intel 486/33 with an Asus EISA board and Adaptek SCSI controller. I went self employed and I think the PC cost ~£3200 when current.

Gronich26
Z80 in my ZX81 with wobbly 16k ram pack.

I remember glaring at my parents for opening the fridge door as it used to crash mine haha

SWTPC 6800/2 Kit with 8k ROM/PROM and 8k static RAM. Built in 1978

My first CPU was Intel Pentium III 450Mhz later I put an geforce 3 ti and 512 ram memory. It was the pc thad pushed me to be a PC Technician, IT and Programer. :D

First standalone CPU purchase I think was a Pentium II 200 or 233mhz

But first PC system was a 486 DX2/66 (Cyrix processor). I remember being annoyed and puzzled by the performance difference compared to my mate's Intel DX2/66. As far as I was concerned, they ran at the same clock speed so should perform the same. Back then I had no concept whatsoever about IPC. Doh.

Zilog Z80 1 mhz followed shortly by a Motorola 68000 2 mhz

Oh wow, what a question. Such a long time ago and so many chips later but the first PC I ever had was a self-built beast running an Intel Pentium 200 MMX. Those were the days :P

Celeron 533mhz in 2000… well you have to start somewhere! :embarrassed:

Does the C7420 upgrade module for my Philips Videopac count? It upgraded the CPU/RAM, so you could create programs in BASIC.

3.574 MHz Z80 microprocessor and 16KB of RAM

First CPU in a PC: a 486SX, on an add-in card for my Acorn RiscPC.

First CPU as part of a build: Duron 600, which overclocked to 900, lovely.

I forgot I had a 8086 with the math co processor to omg I am old and a p4 2.8 gig to in all of them and I sure others I tried to overclock in there lol

First PC: AMD K6-II 300Mhz
First build: AMD Ahtlon 64 3200+ (Engineering sample which I manually clock to stock speeds regularlly)

First CPU in a PC: Pentium 3

First CPU as part of my own build: Pentium 840 (sandybridge)

i8086 8mhz, thought I won the lottery ;)

First one I ever personally purchased was an AMD K6 II 500. Could not afford an Intel cheap. Then first student loan payment went on a 1GHz K7.

actual first was an intel 386 SX16Mhz didn't even even had a math co-processor installed in the other slot on the motherboard.. lol

My first computer was the BBC model B with a 6502 cpu. Next came the AMD athlon k7 500mhz - bought just after its launch with a voodoo 3 gpu.

First pc I had and build was with a AMD K6-2 350.

Pentium D 805.

Ah. Memories.

the 386DX 40Mhz :) but it was soldered to the mobo so its maybe disqualified :)
Then maybe the 486dx2 66

The first CPU I bought was a Pentium 133 back in '96. I used it to upgrade from a Pentium 120.

Athlon 800, back when AMD really was the sensible choice. They just kicked out so much heat :D

My first actual CPU purchase (not counting the complete PCs I'd inherited from my dad previously) was some flavour of Celeron II that came in a big, black slot 1 package.

386sx 25 next was P90. And then first Overclocking: Celeron 266 to 400.

A 486 DX2-66 in 1995! I think it was AMD…

My early microprocessors are as follows,

Motorola 1MHz 6502 for a project :rockon:
Zilog Z80A for another project :rockon:
Intel 8088 8Mhz for IBM compatible :surprised:
Cyrix V20 due to the claim it was 20% faster!
486sx 25Mhz (No floating point coprocessor) over clocked to 33Mhz!

First PC that was mine was a Pentium 200 MMX (which I bough aged 16 with my savings)
First PC I built from scratch was a Pentium 2 350 after I killed the P200 with a bad flash update…

Z80-A at 1mhz. Killed it.
Next was a MOS 6502, that survived
Next was a Motorola 68020, then a 68030LC then a 68040 at the mindblowing speed of 33mhz. Replaced with a 40mhz version.
PC wise 386/33 etc. etc. Last was a Xeon E5645 for this very puter now, 6 cores/12 threads at 2.4ghz for normal stuff

First CPU not in a prebuilt PC was an Intel P2 400 which was one of those weird slot CPU's, my very first one included with a computer was a Pentium 60. First family PC was a 486 sx 33.

First Pc was an old Amstrad with an 8086 and dual 5.25 floppy drives,

irs bought cpu was a Cyrix Pr200+

Was either an HD6303 or a Z80A, I had both and some sram+eproms for breadboarding up little projects, can't remember which I bought first though.

First PC cpu was a 386-40, unless you count plug-in cards as I had an 8MHz 286 board plugged into my Atari ST so I could run DOS programs without needing another computer.

From a self build, an AMD of some description (though I cannot remember the exact model). The earliest that I can actually remember the details of was 2500+ Barton, for which I also bought a Shiv, although this was around self build number 4, and was the second longest lasting PC I owned! Ended up with an Ex's brother as a Championship Manager machine…

The only one that I've bought is the i5 6500. I have had others but they where in pre-built computers.

i7 920

80286 and an 80287 math co-processor… yes, I'm that old…

Motorola 6808 processor was the first processor I purchased for a computer I designed, however the first PC processor I put together was a Intel 286, The first CPU I owned was a 8088 in a Tandy Color Computer 2 (COCO 2)

486 dX 66 with 16MB RAM
NC with DOS command
On this one i've played DOOM & DOOM2 etc.

386DX33 and a 387 coprocessor!

Intel Core 2 Quad - Q6600. Overclocked to around 3.3GHz for the majority of its life.

Lasted me almost 9 years as well.

Wow I got into this late compared to a lot of you.

My first (and only) CPU I have bought is the i5 6600k in my current build.

Sent from my MI 5 using Tapatalk

First CPU(s) - a pair of Pentium III @ 800 MHz / 256K Cache / 133 MHz FSB for use with an ABIT VP6 MB.

Amd 386-40 :)

AMD Duron k7 1200mhz.I still have the scan of the pc build invoice.
I was very happy because i could watch movie rips and play serious Sam and counter strike 1.6.
Very Fast cpu at the time.Outperformed pentium 2 MX at least two times.Then after 2 years the new pentium 3 camed out, which had 1.8ghz and lot of cache, i remember that pentium 3 was very fine with cossacks game.

Smudger
First CPU within a PC: 486 DX2 66

First CPU on its own: AMD Athlon 3200

Exactley This !!!!

well according to wiki the amstrad CPC6128 ran on a Zilog Z80A @ 4 MHz.
My first proper PC was a Mesh built around an AMD Athlon 700 / possibly 750 (it came running at 760MHz),
my first self-build used an i3-540.

Probably Z80A 1Mhz after shorting out a ZX81's original one with a faulty expansion.

First separate purchase processor was an 8087 but not sure if that counts as it's a co-processor rather than central processor ;)

K6-2 300!

Amd k6-2 300!

AMD 5x86-133 to upgrade a DX2-66 system.
First brand new one I bought would be an Athlon XP 2600+ Barton which I overclocked accidentally by having the board jumpered for 400MHz FSB instead of the 333 it was supposed to run at :D

AMD 586 90mhz

it was a AMD 486sx33mhz then k6-2 400mhz the first Athlon 500mhz and a overclocking DIP board that plugged in to the cpu :) now that I site here and think of all the chips I have bought over the years lol
