# AMD Instinct MI300X

8 Hacker News commenters recommended AMD Instinct MI300X and 6 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months.

**Verdict:** Recommended for large VRAM, competitive throughput and easy availability. Common caveat: the software stack lags Nvidia, missing features like int4 and fp8 quantization.

## Why people recommend it

- More VRAM than Nvidia equivalents (2 comments): "it's a datacenter gpu, and one that actually has more VRAM than the NVIDIA equivalent" ([source](https://news.ycombinator.com/item?id=49180317)) "the higher HBM on Mi300x is really useful for this kind of thing" ([source](https://news.ycombinator.com/item?id=49169491))

## What people warn about

- Software stack lags Nvidia (3 comments): "the fact you cannot even do some very basic stuff on AMD is going to mean you are left unused by researchers" ([source](https://news.ycombinator.com/item?id=47960458)) "int4 quantization not supported. fp8 quantization not supported." ([source](https://news.ycombinator.com/item?id=47930715)) "nowhere near the same software stack, so nobody cares" ([source](https://news.ycombinator.com/item?id=47293463))
