Aired in the Ship Log episode of 2026-09-14. This page is the public record for the story: every fact the show was allowed to assert, with its verbatim source sentence — and every reply and correction, unedited.

What the show asserted (10 claims)

ClaimSource sentence (verbatim)Source
The CUDA-for-AMD-Windows project runs CUDA-targeted Windows applications on AMD GPUs through ZLUDA plus ROCm/HIP.“Run CUDA-targeted Windows applications on AMD GPUs through ZLUDA + ROCm/HIP.”Hacker News (front page)
The only validated hardware for the project is currently the AMD Radeon RX 9060 XT (gfx1200).“Validated hardware is currently AMD Radeon RX 9060 XT (gfx1200) only.”Hacker News (front page)
The validated reference setup uses AMD HIP SDK 6.4.“The validated reference uses HIP SDK 6.4.”Hacker News (front page)
A controlled A/B test on 2026-09-13 ran 10 iterations per runtime on the same RX 9060 XT PPO workload.“A controlled 2026-09-13 A/B ran 10 iterations per runtime on the same RX 9060 XT PPO workload.”Hacker News (front page)
In that A/B test, the public upstream path reached 13,278 median overall SPS versus 12,876 for the recovered custom overlay.“After discarding the first iteration of each trial as warmup, the public upstream path reached 13,278 median overall SPS versus 12,876 for the recovered custom overlay.”Hacker News (front page)
The custom overlay was about 3.03% slower in that workload, so upstream remains the default.“In this workload the custom overlay was about 3.03% slower, so upstream remains the default.”Hacker News (front page)
Historical tuned runs used a different training configuration and reached roughly 70k–109k overall steps/s.“Historical tuned runs used a different training configuration and reached roughly 70k–109k overall steps/s.”Hacker News (front page)
The stable Windows HIP SDK does not ship the full ROCm AI-library stack such as MIOpen, so software requiring cuDNN can need a newer or nightly HIP stack.“The stable Windows HIP SDK does not ship the full ROCm AI-library stack such as MIOpen, so convolution-heavy software that requires cuDNN can need a newer/nightly HIP stack or additional work.”Hacker News (front page)
Project-owned scripts and documentation are MIT licensed, while ZLUDA, AMD ROCm/HIP, NVIDIA CUDA components and PyTorch/LibTorch retain their own upstream licenses.“Project-owned scripts and documentation are MIT licensed. ZLUDA, AMD ROCm/HIP, NVIDIA CUDA components and PyTorch/LibTorch retain their own upstream licenses.”Hacker News (front page)
The recovered DLLs are fingerprinted in manifests/recovered-artifacts.sha256 and are not published as binary blobs.“The recovered DLLs remain fingerprinted in manifests/recovered-artifacts.sha256. They are not published as binary blobs because the original custom wrapper source/provenance is incomplete and the recovered HIP runtime contains third-party AMD binaries.”Hacker News (front page)
