To me m68k seems something like 10 000 times slower than modern hardware, not a million times. From the demo descriptions I get an impression (though there are no benchmarks to be sure) that it's much more limited than what could be done on a m68k.
- cobbzilla 5y agoMore accurate: an early 6502 or Z80 (circa late 70s/early 80s) with speeds in the low MHz range. So a ~40-year regression in performance.
- ganafagol 5y agoAnd a from-0-to-100 gain in privacy. Calling this a "regression" is nonsense.
- cobbzilla 5y agofor non-English speakers: colloquially, performance == speed. this is a regression in speed, I was making GP’s assessment more accurate.
- PeterisP 5y agom68k is the equivalent of those, it's late 70s/early80s, with speeds in the low MHz range (e.g. 7.67 MHz for the version in Sega Genesis) - but I haven't seen claims of FHE having that high of a performance (e.g. sum or filter a million numbers in a second as low MHz allows you to do) but only something an order of magnitude or two slower (e.g. 13ms/core for a bit operation might be treated as comparable to a 0.077 MHz microcomputer; you can parallelize over cores but that computer parallelized over bits), so we're talking about much more than a 40-year regression of performance, as it's slower than the first 1970s microcomputers which themselves were slower than the 1960s minicomputers, so perhaps the 1950s early transistor computers?
- cobbzilla 5y agoYou’re right. The original 68k chip was contemporaneous with the Z80 and 6502. I was thinking of the later chips in the 68k series, which got much faster over the years.
