O AMD Instinct MI300X 192GB é a GPU de aceleração discreta CDNA 3 principal da AMD para inferência e treinamento de LLM em escala. Com 192 GB de memória HBM3 e 5,3 TB/s de largura de banda, supera a NVIDIA H100 80GB em capacidade de memória bruta e largura de banda. Os 1307 TFLOPS FP16, suporte FP8 e a maturidade do ROCm tornam-no o principal produto de IA para data centers da AMD e a principal alternativa à NVIDIA.

Architecture
CDNA 3 powers the Instinct MI300X (GPU-only, 192 GB HBM3) and MI300A (APU with integrated CPU). It features advanced packaging with up to 12 chiplets and native FP8 support for AI inference.
AI Relevance
The MI300X with 192 GB HBM3 can hold even the largest open-weight models (70B+ at full precision) entirely in GPU memory. FP8 support and mature ROCm stack make it a serious competitor to NVIDIA H100 for AI inference.

What will limit you first
This setup is broadly balanced for this model.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Best upgrade itinerary
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Unlocks 4 additional models that do not fit on the current setup.

AMD Instinct MI300X 192GB (192 GB VRAM) can run these top models: DeepSeek V4 Flash (score: 96/100), Qwen 3.5 122B A10B (score: 95/100), Devstral 2 123B Instruct (score: 95/100). See the full compatibility list above.
AMD Instinct MI300X 192GB has 192 GB of VRAM available for AI model inference. This determines which models and quantization levels you can run locally.
Yes, AMD Instinct MI300X 192GB is excellent for running LLMs locally with top compatibility scores above 80/100.
For coding on AMD Instinct MI300X 192GB, we recommend Devstral 2 123B Instruct. It achieves 59.9 tokens per second with 256K context window. This model is a direct match for coding. It belongs to a current frontier family for local AI. It fits natively with comfortable headroom. Known channels: huggingface, lm-studio.
There are 3 upgrade path(s) from AMD Instinct MI300X 192GB: AMD Instinct MI300X 192GB, AMD Instinct MI325X 256GB. Upgrading would unlock larger models and faster inference speeds.
Yes, AMD Instinct MI300X 192GB with 192 GB of usable memory can run Flux.1 Dev at FP16 natively. Flux is a 12B parameter diffusion transformer that produces high-quality images. You can also run the Schnell variant for faster generation.
AMD Instinct MI300X 192GB (192 GB VRAM) can handle various AI generation tasks beyond LLMs. For image generation, SDXL and Stable Diffusion 3.5 run well. Flux.1 Dev also runs natively for state-of-the-art image quality. For video, LTX Video 2.3 can generate short clips. Check the AI Capability Matrix above for detailed compatibility.
AMD Instinct MI300X 192GB is excellent for AI image generation. With 192 GB of usable memory, it runs all major diffusion models including Flux.1, SDXL, and Stable Diffusion 3.5 at full precision. You can generate high-resolution images quickly and even handle video generation models.
Yes, AMD Instinct MI300X 192GB with 192 GB of usable memory can run Qwen 3.5 27B at Q8 (near-lossless, ~28.9 GB) or even FP16 (~55.4 GB) depending on your context needs. This setup provides an excellent experience with this model. Use Ollama or vLLM for best results.
With 192 GB VRAM on AMD Instinct MI300X 192GB, use Q8_0 for most models — it is near-lossless and you have the memory for it. For 70B+ models, Q6_K offers excellent quality. Reserve Q4_K_M for 100B+ models or when you need maximum context length.
AMD Instinct MI300X 192GB already has strong memory bandwidth, so the next limit is often memory capacity and context headroom rather than raw decode speed. For local LLMs, fit first and bandwidth second is the right mental model.
AMD Instinct MI300X 192GB supports up to 8× GPU scaling via Infinity Fabric at 896 GB/s. With 8× GPUs, you get 1536 GB effective memory with a 0.88× scaling factor per GPU. This enables running models like Qwen 3.5 397B A17B and Kimi K2.5 that don't fit on a single card.
Infinity Fabric is recommended for AMD Instinct MI300X 192GB multi-GPU inference, providing 896 GB/s interconnect bandwidth with only 12% scaling overhead. PCIe-only setups work but have higher overhead (~25%) due to limited inter-GPU bandwidth.
