niente affatto
erano entrambi computer a 8 bit e sotto alcuni aspetti era più potente lo speccy, ma ahimé non rendeva in fatto di "estetica giocosa"
negli anni 80 erano i più diffusi insieme all'amstrad (che occupava l'ultimo posto in fatto diffusione)
non sono ferratissimo ma ecco, ad esempio, l'opinione di qlk nerd expert
Cost
The ZX Spectrum was consistantly cheaper than it's CBM made rival. This was always true, right across the model range, and even when you include disc drives for both machines. This factor alone is probably responsible for more Spectrum sales than any other.
Spectrum 1, Commodore 0
CPU
The C64 was based upon the popular (at the time) 6502 CPU, which ran at an amazing 1.0MHz. Well, actually, not so amazing, as the Spectrum's Z80 ran at 3.5MHz, giving it a clear advantage for CPU intensive games. Like it or not, this generally made 3D games *much* more playable on the Spectrum.
Spectrum 2, Commodore 0
Graphics
Oh dear. It was all going so well for Sinclair, until now. You see, the Spectrum had only one graphics mode. 256x192, in 16 colours. You were limited to two colours per 8x8 block, which gave Commodore owners endless opportunities to laugh at the dreaded attribute clash in games which attempted to use more than 2 colours on screen.
The C64, however, had a custom graphics chip which could handle 320x200 with 16 colours in a similar fashion to the Spectrum, but also offered a 160x200 mode which allowed for four colours per 8x8 pixel. Of course, a side-effect of this was that everything looked chunky, giving the Spectrum owners something to laugh at.
What really made the C64 the better computer in terms of graphics though, was the implementation of hardware scrolling and sprite graphics. Sprites are graphics which are overlaid on top of the normal screen without affecting the colours below, so there was no Speccy-style attribute clash in Commodore games. As they were handled by custom hardware they also moved around much more smoothly than the Spectrum could usually manage, as it had to rely on it's CPU to do everything
Spectrum 2, Commodore 1
Sound
Custom hardware to the rescue of the C64 again! While the Speccy had only a single tone generator linked to a loudspeaker (Beep!), the Commodore had the infamous SID chip- basically a small but powerful three channel synthesizer which was output through the modulator to the TV. Listening to Spectrum games after owning a C64 is likely to make your ears bleed. If you need proof as to the quality of music in C64 games, look no further than the recently released dance track "Zombie Nation" in which the main riff was 'borrowed' (Although without the authors consent) from the C64 game "Lazy Jones". Incidentally, the threat of legal action did result in the author receiving a cash settlement, which was nice.
Spectrum 2, Commodore 2
Playability
Grow up, they're both equal in this respect!
Spectrum 3, Commodore 3
BASIC
If you wanted to learn to program on your home computer, you'd have to spend extra cash to do anything useful with your Commodore. While the Speccy had graphics commands as standard, the C64 did not, thanks partly to it's PET roots and partly to Commodore's rush to get it released.
Spectrum 4, Commodore 3
Non-games applications
The rubber nightmare that was the early Spectrum's keyboard did little to convince the buying public that they were getting anything other than a cheap games machine that you could program. The C64 on the other hand, was marketed as a business machine. It had a real keyboard, real disk drives and real printers (As compared to the Speccy's tiny thermal silver roll thing).
Eventually this lead to real applications being developed for it- Word processors, art packages, and even a GUI in the form of GEOS, which can still be purchased today!
Final score: Spectrum 4, Commodore 4
So there you have it- In keeping with almost every playground argument since the dawn of time, there's no clear "winner" because it depends what you want. Want the cheapest? Buy the Spectrum. Want better graphics & sound? Buy the C64.
I still think the C64 is the better computer.
Note: Before anyone asks, I haven't mentioned RAM for the simple reason that it depends on what year you're doing the comparison. The spectrum range had 16k,48k and then 128k, and the C64/C128 had 64k and then 128k. In the end, it didn't make a lot of difference!
