Bitmain
Designs the BM-series chips in its Antminers. Its chips are also in every open-source Bitaxe-style board here. It has published the process node only for its older chips.
9 named chips in the devices here; best device 8.9 J/TH.
ASIC chips
The chips inside
Every heater and miner here does its work on SHA-256 chips. This page shows which chip is in each one, how the chips line up in generations, who makes them, how well the devices using them perform, and where each one is fitted.
- 17 named chips, from 4 makers
- 101 of 208 devices with a named chip
- 180 of 208 devices whose chip maker we know
- 80 → 8.9 J/TH: the best device of the 2016–2018 chips against the 2025–2026 ones
Generations
We group the chips by the year their first miner was launched or announced. Each new generation uses less energy for the same work. A device's efficiency also depends on its power supply, fans and settings, so the best device using a chip is a guide to the chip, not a lab figure.

Hollow: part number not published
Lower is better: each mark is a chip, placed at the year its first miner was launched or announced and the efficiency of the best device here that uses it as its main chip. Hover, tap or tab to a mark for its numbers; click it, tap it again or press Enter to see its devices. The same numbers are in the chip table.
Where no source dates a chip, it sits at the launch of its first device here. A hollow mark stands for a maker's chips in one miner series whose part number isn't published, such as MicroBT's M70 series. Not in the chart: BM1397 and KF1968, because no device here with one of them as its main chip has an efficiency figure.

MicroBT says its M50S runs on a Samsung 5 nm chip and that the M50 is also 5 nm (some later VK boards of the M50S, M50S+ and M50S++ report the 3 nm KF1978's chip ID), and Bitmain's BM1366 (S19 XP) is reported as 5 nm.

Named by device maker Reported by others Part number not published
MicroBT
Designs the chips in its Whatsminers but publishes no part numbers. MicroBT names Samsung as the maker of its M30-series and M50S chips, and TechInsights found the KF1978 on Samsung 3 nm; it has named no foundry for the M60 or M70 series. The KF names come from a TechInsights teardown and from chip IDs in MicroBT's own firmware.

* Reported by an independent source, not confirmed by the maker. "First miner" is when the first miner with the chip was launched or announced. GH/s and W per chip are medians over the devices with a known chip count, for named chips only: a series entry may group several chips. A chip without a sourced first-miner date takes its generation from its first device here.

The chips of MicroBT's M30S series (launched December 2019 to April 2020), made on 8 nm by Samsung Foundry according to MicroBT. MicroBT counts the M3, M10 and M20 as its first three generations and calls the M50 its fifth, so the M30 is its fourth. MicroBT says it used the 8 nm process from the M20 series through the M30 series. This entry stands for those chips as a group: no source names the part, or shows that the M30S, M30S+ and M30S++ share one chip.

KF1968 MicroBT 2021–2022 · 1 device
Chip of MicroBT's M50 series, which MicroBT calls its fifth generation (M50S, M50 and M53). MicroBT says the M50S runs on a Samsung 5 nm processor and that the M50 is also 5 nm. KF1968 is the chip ID seen on the early (VH) M50S boards, so it is very likely that chip. No source ties the name to MicroBT's statement directly. Later M50S boards (VK10, VK30) moved to the 3 nm KF1978.

- MicroBT official news 252, M50-series launch at Bitcoin 2022 (6 April 2022). The M50S (126 TH/s, 26 J/TH) is 'powered by a 5nm processor from semiconductor manufacturing giant Samsung', and the M50 (114 TH/s, 29 J/TH) 'is also fabricated in a 5nm process'. The series (M50S, M50, M53) is called fifth-generation. No part number is given. www.whatsminer.com
- Captured Whatsminer status page: model M50S_VH55, hardware info 'M50S_VH55.H616-CB6V10.P222B-VE2-196803B' (chip field 1968). github.com
- Firmware-derived board table. The M50S has boards VH20–VH50, VJ10–VJ50, VK10–VK30, VK50–VK80 and VL10–VL30, so VH is its earliest board letter. The M50 has VE30, VG30, VH10–VH90, VJ10–VJ40, VJ60, VK40 and VK50. github.com
- D-Central chip-ID notes from its 191-model firmware spec table. They map 0x1968 to the 'KF1968/KF1973 family era — Samsung 5nm (M50/M50S/M30S++ VH-series)' and 0x1973 to 'KF1973/KF1973E — Samsung 5nm (M50/M53/M60 VJ-series)'. github.com
- Census of MicroBT firmware 20240124.11.Rel: 49 of 229 miner profiles carry chip_id 0x1968 and 23 carry 0x1973. It names no models for those IDs. github.com
- Shows the M50S VK10 and VK30 profiles on chip_id 0x1978 (KF1978), not 0x1968, so KF1968 is not in every M50S. github.com
- Parts seller LYS names KF1968, KF1968E and KF1969 as the M50 hashboard chip family on Samsung 5 nm. It lists them for the M50, M50S, M53 and late-production M30S++. Low credibility: it gives no per-version mapping and says the M30S++ moved 'from BM-style to KF-style chips'. lys-sz.com
- D-Central website dataset. It groups the M50/M60 under 'MicroBT K3 (chip_id 0x1920)', '7nm', marked 'Named-only'. This contradicts D-Central's own firmware-derived notes, so it was not used. d-central.tech

The chips in MicroBT's fifth-generation M50 series (M50, M50S, M53, M54, M56 and their + and ++ versions). MicroBT said the M50S runs on a Samsung 5 nm chip and that the M50 is also 5 nm. The models shipped on several hashboard versions with different chips: the early M50S VH boards report chip ID 1968 (KF1968), and some VK boards the 3 nm KF1978.

KF1978 MicroBT 2023–2024 · 8 devices · best 22 J/TH
MicroBT's 3 nm chip. TechInsights found it was made on Samsung's SF3E process, Samsung's early 3 nm gate-all-around process. It was first documented in the WhatsMiner M56S++, launched on 18 May 2023 alongside the M50S++ and M53S++. MicroBT's firmware also gives its chip ID (0x1978) to some VK hashboard versions of the M50S, M50S+ and M50S++, and of the first M60-series models (M60, M60S, M63S and M66S).

M60 series chips MicroBT · part number not published 2023–2024 · 22 devices · best 15.5 J/TH
The chips in MicroBT's M60 series (launched 24 October 2023). MicroBT's firmware, as recorded by D-Central, gives the 3 nm KF1978's chip ID to some board versions: M60 VK10, M60S VK10, M63S VK30 and M66S VK40, and a status capture from an M60S VK40 reads the same chip field. D-Central's notes put M60S VL boards and the M63 and M66 on chip ID 0x1980, and M60S++ VM boards on 0x1990, neither with a published name. The chip in the other versions is not known.

The ASIC in Auradine's Teraflux 2800 series (AT2880 and AI3680), which Auradine introduced in November 2023 and began shipping in July 2024, described as 'built with 3-nanometer (nm) silicon ASIC technology'. The AH3880 hydro model (data sheet March 2025) is grouped here as well. Bitcoin.com reported in July 2023 that Auradine's first Teraflux line used a 4 nm chip. Auradine called the chip in its next systems (announced November 2025, volume from Q3 2026) 'third-generation'. It did not number the earlier ones.

The S21j XP Hyd.'s chips each do about 3.9 TH/s, far more than any known BM1368 or BM1370 model, so it may use a different chip.

Block says the Proto Rig runs on its own chip but has not named it. Block made its 5 nm design only as prototypes (2023) and bought Intel mining ASICs instead. It finished a 3 nm design in April 2024 and taped it out with an unnamed 'leading global semiconductor foundry' by November 2024. In July 2024 Block said its first system would start on an older-generation chip and move to the 3 nm one through swappable hashboards.

How sure we are
Makers rarely print the chip on the box. We looked for it in each maker's own pages and firmware, then in repair guides, open-source miner software, teardowns and reviews. Every device's chip and sources are on its own page.
7 devices with an unpublished part number have a named chip in some versions, such as the KF1978 on some Whatsminer M60 boards. They count here by their main chip.
- 57 Named by the device's maker (27%)
- 44 Reported by an independent source (21%)
- 79 Chip maker known, part number not published (38%)
- 8 No chip of its own (4%)
