Not at all.
Frame rates varies widely, resolutions varied widely. The exact behavior was in e.g. pixels/frame, and you had to work hard to get the same feel on a 50hz 256x192 4Mhz z80 ZX Spectrum, as you did on the 60hz 160x200 1Mhz 6510 C64 ; Also abilities differed widely : C64 had hardware sprites, tile (text) mode and hardware scrolling; Spectrum had nothing but a frame buffer (it did have a much faster memory copy instruction, LDIR, but that didn’t compete with hardware scrolling).
And the original arcade, of course, had multiple playfield with hardware scaling, and often game-specific hardware (in the early days at least)
