MOS 6502 vs. Zilog Z80: The Battle for 8-Bit Supremacy
DE | EN

The CPU Philosophies

MOS Technology 6502 / 6510
Chuck Peddle (1975) | ~1 MHz | Quasi-RISC

Ultra-lean register set (A, X, Y), fast zero-page memory addressing, and deterministic cycle counts. Lower raw clock frequency, but most instructions executed in just 2 to 4 cycles.

Zilog Z80
Federico Faggin (1976) | 3.5 – 4.0 MHz | CISC

Extensive instruction set, shadow register bank, built-in DRAM refresh logic, and high clock speeds. Required more cycles per instruction, but provided immense coding flexibility.

Legendary Machines

Commodore 64 (1982)
MOS 6510 @ 0.985 MHz (PAL) | 64 KB RAM | VIC-II | SID 6581

The definitive 8-bit standard. Dedicated sprite collision, raster interrupt control, and an analog synthesizer chip made it the ultimate gaming and demoscene platform.

Sinclair ZX Spectrum (1982)
Z80A @ 3.50 MHz | 16/48 KB RAM | Ferranti ULA

Sir Clive Sinclair's British marvel. Famous for rubber keys and "attribute clash" (1 byte of color attribute per 8x8 block), but unmatched in accessibility and price.

Amstrad / Schneider CPC 464 (1984)
Z80 @ 4.0 MHz | 64 KB RAM | CRTC 6845 | AY-3-8912

The all-in-one workhorse complete with bundled monitor and built-in cassette/3-inch disk drive. Praised for ultra-fast Locomotive BASIC and vibrant Mode 0 graphics.

Atari 800XL (1983)
MOS 6502C @ 1.77 MHz | 64 KB RAM | ANTIC | GTIA | POKEY

Jay Miner's architecture precursor to the Amiga. ANTIC served as an autonomous display-list graphics coprocessor years ahead of its competition.
