C64 VS SPECTRUM VS AMSTRAD
THREE MACHINES, ONE WAR. WHO REALLY WON THE 80s?

► THE CONTEXT: THREE MACHINES IN THE SCHOOLYARD

If you grew up in the 1980s with a microcomputer at home, you already know this was not just technology. It was identity. The kid with a Commodore 64 looked down on the Spectrum owner, who in turn explained to the Amstrad kid that his machine was "a cheap clone". And all three of them — secretly — marvelled at the C64 demos in magazines without quite believing what they were seeing.

The microcomputer war of the 80s was not won by a technical argument. It was won by whoever had more games, better friends who lent tapes, or simply the parent who paid the bill. But forty years on, it's worth sitting all three contenders in the ring, switching on the screens, and seeing who can last the most rounds.

Let's start with what caught the eye first. The Commodore 64 stepped into the ring with heavy artillery: the VIC-II chip, capable of moving 8 hardware sprites simultaneously, with built-in collision detection and a resolution of 320×200 pixels in 16 colours. Programmers could use raster tricks to squeeze more colours on screen, and the C64 demo scene would spend decades proving what that chip could do in expert hands.

The ZX Spectrum, for its part, had a well-known problem called attribute clash — the colour curse. The screen divided colours into 8×8 pixel cells, which meant that when two sprites overlapped, their colours "bled" into each other, producing that distinctive — and much-criticised — effect you see in Spectrum games. Without hardware sprites, programmers had to move graphics using raw CPU cycles, which was slow and limiting. That said: given those constraints, some programmers did remarkable things.

The Amstrad CPC arrived in 1984 with a more balanced visual proposition: the CRTC chip allowed up to 27 simultaneous colours from a palette of 4,096, and although it also lacked hardware sprites, the video memory was better structured than the Spectrum's. CPC games tended to have more saturated colours and more detailed backgrounds — a point in its favour that many overlooked at the time.

If graphics was a three-way fight, sound was an outright monologue. The SID (Sound Interface Device, MOS 6581) of the Commodore 64 is, without exaggeration, one of the most legendary audio chips in the history of computing. Three synthesis voices with four different waveforms (triangle, sawtooth, pulse and noise), low/high/band-pass filters, independent ADSR envelopes and ring modulation effects. It could produce music that sounded like it came from a professional synthesiser of the time.

Rob Hubbard, Martin Galway, David Whittaker, Ben Daglish, Fred Gray... an entire generation of video game composers built their reputations on that chip. SID tunes today have millions of plays on YouTube and still move people who hear them forty years on. The SID was not just a sound chip; it was a musical instrument.

The original Spectrum came with a single-channel beeper. A small internal speaker capable of generating basic bleeps. Programmers managed surprising things with it through timing tricks, but it was like asking an orchestral triangle to perform a Beethoven symphony. The Spectrum 128, which arrived in 1985, added the three-voice AY-3-8912 chip — the same one fitted to the Amstrad — and noticeably improved the situation, but it came late.

The Amstrad CPC, with its AY-3-8910 three-voice chip, was honest and functional. It produced recognisable music and decent sound effects. It was not the SID, but it was infinitely better than the original Spectrum's beeper. In this round, the CPC clearly beat the Spectrum but lost without argument to the C64.

This is where things get complicated. The ZX Spectrum was the undisputed king of the library in the European market — especially in the UK and Spain. It is estimated that over 15,000 titles were published for the Spectrum throughout its lifespan. The reason was simple: the Spectrum was cheap, popular and easy to program in Z80, a processor almost everyone knew. Dinamic, Opera, Erbe, Topo, Zigurat... Spanish software of the 80s came out first on Spectrum and was then ported to everything else.

The Commodore 64 had a library of superior quality in many titles — especially in games of Anglo-Saxon origin, where the C64 was the reference platform. Ocean, Activision, EA, Lucasfilm Games... all prioritised the C64 for their highest-quality versions. The catalogue exceeded 10,000 titles, with a noticeably higher proportion of top-tier games than the Spectrum.

The Amstrad CPC, sharing the Z80 processor with the Spectrum, received Spectrum conversions with relative ease, though not always well optimised. The catalogue stood at around 3,000–4,000 titles, smaller but with the advantage that many games made better use of the hardware's graphical capabilities.

The computers of the 80s were not just game consoles. Many households bought them thinking of "learning computing" — a promise parents sold to justify the expense and that children accepted happily as long as it came with games. In that context, usability mattered.

The Amstrad CPC won this round without question. It came with a colour monitor included, an integrated datasette or disk drive depending on the model, and a reasonably solid BASIC. It was the most "complete" out of the box, which made it attractive for families who wanted an all-in-one solution without buying extra peripherals.

The Commodore 64 was powerful but required additional investment: you needed a separate television or monitor plus a datasette or disk drive. The C64's BASIC was limited when it came to accessing the hardware — there were no native commands for sprites or the SID; you had to use POKE and PEEK directly. That made it intimidating for beginners, though perfect for anyone who genuinely wanted to understand how a machine worked at a low level.

The ZX Spectrum had the most elegant BASIC of the three — designed by Nine Tiles for Sinclair, with keywords as physical keys and smart error handling — but the rubber keyboard of the original model was an ergonomic disaster. That improved with the Spectrum 128 and the +2, but the memory of those squidgy keys was forever burned into the collective consciousness.

Money always had the final word. In 1984, a ZX Spectrum 48K could be bought for around £130 in the UK — affordable for a middle-class family. The Commodore 64, priced at roughly £250, was nearly double. And the Amstrad CPC 464 came in around £230 with monitor included, making it comparably cheaper than the C64 when you counted everything in.

This price difference largely explains why the Spectrum dominated in the UK and Spain: it was the computer more families could actually afford. The C64 was the machine for those who could spend more, or for those who waited until the second or third year when prices dropped. The history of home microcomputers is, in part, a history of economic barriers.

Forty years on, the true winner is measured in active community, in new demos still being released, in music that still moves people. And here the Commodore 64 wins by a landslide. The C64 demo scene did not just survive — it evolved. In 2025, new C64 demos continue to appear that exploit the VIC-II in ways that would have seemed impossible in 1985. SID music has over 70,000 songs archived in the HVSC (High Voltage SID Collection). There are new games, new cartridges, new hardware revisions.

The ZX Spectrum also has a very active community, particularly in the UK and Eastern Europe — Poland, Russia — where the Scorpion clone and others were enormously popular. Spectrum nostalgia across Europe is intense and real, with retro events where Dinamic and Opera tapes remain the stars of the show.

The Amstrad CPC is perhaps the one with the least presence in popular retro culture today, though it has passionate devotees — especially in France, where it was the dominant platform — who continue publishing games and tools. Less visible, but not forgotten.

► THE QUESTION NOBODY ANSWERS WITH DATA

Which was best? The technical answer is above. But the real answer — the one that actually matters — is which one was yours. Because the best computer of the 80s was not the one with the most colours or the best sound chip. It was the one sitting on your desk when you were twelve, the one that loaded games with that unmistakable squeal from the tape, the one that taught you without your noticing that machines do what you tell them to.

The Commodore 64 won the technical war. The Spectrum won the battle of the European catalogue. The Amstrad won the practicality war. And all three together won something more important: they shaped an entire generation of programmers, digital musicians and designers who still feel a jolt in the stomach when they hear the sound of a datasette loading.
