 @hexa:lossy.network | if you must get a low power machine for home infrastructure, make sure it supports AVX | 17:25:48 |
| @hexa:lossy.network | https://github.com/NixOS/nixpkgs/issues/358973 | 17:26:02 |
| @hexa:lossy.network | tensorflow consumers on 24.11 crash with SIGILL without AVX (not AVX2). | 17:26:53 |
| @hexa:lossy.network | an N100 has AVX2 for example | 17:27:26 |
 K900 | What is even out there still that doesn't have AVX1 | 17:27:54 |
| @hexa:lossy.network | I suspect Celeron and Pentium | 17:28:09 |
| @hexa:lossy.network | * I suspect Celeron and Pentium CPUs | 17:28:11 |

| @hexa:lossy.network | these were the two CPUs for which I received bug reports | 17:28:54 |
| @hexa:lossy.network | and the Penitum J6005 from 2021 also doesn't have AVX | 17:29:33 |
| @hexa:lossy.network | I'd say these series are meh. | 17:29:41 |
| K900 | Wait what | 17:29:43 |
| K900 | Aren't those just little cores | 17:29:49 |
| @hexa:lossy.network | * and the Penitum N6005 from 2021 also doesn't have AVX | 17:30:04 |
| K900 | ...or do little cores on higher end stuff also not have AVX? | 17:30:04 |
| @hexa:lossy.network | the N6005 has 4 Tremont Cores https://en.wikipedia.org/wiki/Tremont_(microarchitecture) | 17:34:24 |
| @hexa:lossy.network | so yeah, all low power cores | 17:34:48 |
| K900 | OK so the small cores have AVX starting with Gracemont | 17:36:28 |
| K900 | And Tremont has only ever shipped as a small core in the one weird Lakefield chip | 17:36:45 |
| K900 | So basically pre-2020 atoms | 17:39:27 |
| K900 | And OG Bobcat | 17:40:46 |
| K900 | But I really hope no one is running Bobcat in 2024 | 17:41:12 |
| @hexa:lossy.network | ugh, yeah no 😄 | 17:42:46 |

What is even out there still that doesn't have AVX1
Bunch of low-power devices out there :) My CPU from a TerraMaster NAS doesn't have it, bought this year, so I'm guessing quite a few out there

| 17:43:52 |
| K900 | So one of those older Atoms? | 17:43:59 |
| victorbjelkholm | Celeron N4505 in my case | 17:44:25 |
| @hexa:lossy.network | was mentioned above already | 17:44:52 |
| victorbjelkholm | launched in 2021 apparently, but TerraMaster (and I guess others) are still selling end-user appliances with those in them | 17:45:26 |
