Running DeepSeek-V4-Flash on MI300X: Software Gaps and Cost Tradeoffs
June 2, 2026
MI300X offers 192GB HBM3 versus H100's 80GB at roughly half the list price, with on-demand availability while H100 capacity is sold out and rental prices up 40% over five months. Doubleword's writeup details the practical software friction of bringing up DeepSeek-V4-Flash on AMD hardware, noting the gap is narrowing on newer MI350X and MI355X parts.
