PC builds for Mistral Small 24B

A minimum build, the one we'd recommend, and a max-performance build — every part chosen for technical fit and checked for compatibility.

Hardware requirement

Estimated

Running Mistral Small 24B as Q4_K_M in Ollama at ~8,192 tokens of context.

How this is calculated
Model weights
derived
13.7 GB 23.572 billion parameters × 0.58 bytes/param (Q4_K_M) ≈ 13.7 GB.
KV cache (context memory)
derived
1.3 GB 8,192 tokens × 40 layers × 2 × 8 KV heads × 128 head dim × 2 bytes ≈ 1.3 GB. Grows with context length.
Runtime overhead
estimate
1 GB Fixed VRAM overhead for Ollama (activations, CUDA context, fragmentation headroom).
Total VRAM to run fully on GPU
estimate
16 GB Weights + KV cache + overhead. This is what you need to keep the whole model on the graphics card for full speed.
Recommended system RAM
estimate
32 GB Headroom to load the model, run the OS, and hold any layers offloaded from the GPU. Rounded up to a standard kit size.
Storage
estimate
2 TB NVMe recommended Local model files are large (often tens of GB each). An NVMe SSD keeps load times reasonable.

Memory figures are estimates derived from published model facts using a fixed method. They are not benchmarks. We do not publish tokens-per-second figures because we have no measured source for them.

Compatibility: Compatible
  • This model needs about 16 GB of VRAM under lean settings. The GeForce RTX 3090 Founders Edition (24 GB) is the most affordable card that holds the whole model on the GPU.

  • Processor
    AMD Ryzen 5 5600X
    $130

    Local AI inference runs on the GPU, so a capable budget CPU like the AMD Ryzen 5 5600X keeps costs down without holding the model back.

  • Motherboard
    Gigabyte B550M DS3H
    $100

    Matches the CPU socket (AM4) and DDR4 memory; a solid value board with room to expand.

  • This model wants about 32 GB of system RAM; the 32 GB DDR4 kit covers it with headroom for the OS and offload.

  • Storage
    Crucial P3 Plus
    $62

    1 TB of NVMe — local model files are large (tens of GB each), and NVMe keeps load times short.

  • Keeps the CPU cool and quiet under sustained load; compatible with the chosen socket.

  • Power Supply
    MSI MAG A750GL PCIE5
    $110

    Estimated system draw is about 528 W; the 750 W unit leaves headroom for GPU power spikes and efficiency.

  • Fits the motherboard form factor and has clearance for the graphics card (360 mm).

Compatibility: Compatible
  • This model needs about 16 GB of VRAM. The GeForce RTX 3090 Founders Edition (24 GB) holds it with comfortable headroom for longer context and running other apps alongside it.

  • Processor
    AMD Ryzen 5 7600X
    $201

    The AMD Ryzen 5 7600X is a modern DDR5 platform — plenty for feeding the GPU, prompt processing, and everyday work, with an upgrade path.

  • Matches the CPU socket (AM5) and DDR5 memory; a solid value board with room to expand.

  • This model wants about 32 GB of system RAM; the 32 GB DDR5 kit covers it with headroom for the OS and offload.

  • Storage
    Samsung 990 Pro
    $170

    2 TB of NVMe — local model files are large (tens of GB each), and NVMe keeps load times short.

  • Keeps the CPU cool and quiet under sustained load; compatible with the chosen socket.

  • Power Supply
