Hardware data across eras

RetroFlops

RetroFlops places the Apollo Guidance Computer and classic consoles beside Apple Silicon and modern GPUs. Each catalog figure includes its source, exact locator, method, and evidence status.

How the numbers are handled

There is no universal RetroFlops score. MIPS, DMIPS, instructions per second, FLOPS, SPEC results, memory bandwidth, TDP, and whole-system power draw stay separate. A multiplier appears only when the metric, method, benchmark identity, and device scope match, and both figures are confirmed and approved. reported and rumored figures remain visible, but stay provisional and never feed automatic multipliers.

Missing data is explicit. unknown means research found no acceptable figure; not-applicable means the quantity does not exist for that hardware. Neither is represented as zero. Every multiplier shows its formula, inputs, rounding rule, and caveats.

Prepared comparisons

Each has at least one valid multiplier and a useful hardware observation. Other prepared comparisons remain on the Compare page as methodology examples.

  • 2 records · 3 multipliers

    Two guidance computers, one clock

    The Apollo Guidance Computer and the Saturn Launch Vehicle Digital Computer ran at the same 2.048 MHz and were not the same speed.

  • 3 records · 4 multipliers

    A decade of Commodore clocks

    Commodore 64, Amiga 500 and Amiga 1200 in their PAL forms. Their clock rates rose fourteen-fold across ten years, while their memory capacities remain separate measurements.

  • 4 records · 9 multipliers

    Four consoles, four clocks

    PlayStation, Nintendo 64, Dreamcast and PlayStation 2 form the widest comparison the catalog supports. It shows a metric that survives four columns while its neighbors do not.

See every prepared comparison, build your own from two to four records, or read one metric over time.

Where to start

This is an editorial selection. The catalog has no "fastest" label.

  • 1966

    Apollo Guidance Computer (Block II)

    The computer that flew Apollo. A 31.7 kg, 70 W machine with 2048 words of erasable memory and 36 864 words of woven read-only rope, carried by both the command module and the lunar module.

  • 2000

    Sony PlayStation 2

    A 294.912 MHz Emotion Engine rated at 6.2 GFLOPS, 32 MiB of Rambus main memory at 3.2 GB/s, and a rasterizer whose 4 MiB frame buffer sits on the die behind a 2560 bit bus.

  • 2022

    NVIDIA H100 Tensor Core GPU (SXM)

    34 TFLOP/s of FP64 and 67 of FP32, 80 GiB of memory at 3.35 TB/s, and a 700 W ceiling. Its floating-point figures state their precision.
