RTX 5070 12GB can't get to Llama 4 Scout 17B at any price. Here's what actually can.

Llama 4 Scout 17B at Q4_K_M needs 68.2 GB once weights, KV cache at 8K context and framework overhead are counted. RTX 5070 12GB offers 12 GB, leaving you 56.2 GB short. 128 GB of unified memory leaves about 96 GB for a model after the OS takes its share, which holds Llama 4 Scout 17B at Q4_K_M.

What to do

128 GB of unified memory leaves about 96 GB for a model after the OS takes its share, which holds Llama 4 Scout 17B at Q4_K_M.

What it needs

Memory is fixed at purchase on these machines — choose the capacity you will still want in three years

What we checked

Unified memory: 128 GB, of which roughly 96 GB is usable by a model
Model requires 68.2 GB at Q4_K_M

Other ways to get there

Rent a GPU by the hour instead — You want this daily, so renting is the way to try Llama 4 Scout 17B before spending on hardware — not the long-run answer if the usage holds.
Consider waiting this market out — DDR5 kit prices are roughly 3-4x their mid-2025 level, and the shortage is expected to run into 2027. Relief is not expected before 2027-Q4. Meanwhile you have a way to run this that costs nothing extra.

What we ruled out, and why

96GB DDR5 kit (2x48GB) — More memory would let this model load, but the parts of it living in system RAM have to travel over PCIe, so it would run at roughly 2.3-4.7 tok/s — slower than reading speed. More VRAM, not more RAM, is what this needs.
128GB DDR5 kit (4x32GB) — More memory would let this model load, but the parts of it living in system RAM have to travel over PCIe, so it would run at roughly 2.3-4.7 tok/s — slower than reading speed. More VRAM, not more RAM, is what this needs.

Market conditions: DDR5 kit prices are roughly 3-4x their mid-2025 level, and the shortage is expected to run into 2027. Relief is not expected before 2027-Q4. Source, checked 2026-08-26.

Questions people ask about this pairing

Can an RTX 5070 12GB run Llama 4 Scout 17B?

Not as it stands. Llama 4 Scout 17B needs 68.2 GB at Q4_K_M and this machine has 12 GB available, a shortfall of 56.2 GB. 128 GB of unified memory leaves about 96 GB for a model after the OS takes its share, which holds Llama 4 Scout 17B at Q4_K_M.

Would more system RAM fix this?

More memory would let this model load, but the parts of it living in system RAM have to travel over PCIe, so it would run at roughly 2.3-4.7 tok/s — slower than reading speed. More VRAM, not more RAM, is what this needs.

Should I wait for prices to come down?

DDR5 kit prices are roughly 3-4x their mid-2025 level, and the shortage is expected to run into 2027. Relief is not expected before 2027-Q4. The current estimate for relief is 2027-Q4. If you can run this some other way meanwhile, waiting is defensible; if you cannot, the part still does the job today.

Does a longer context change what Llama 4 Scout 17B needs here?

Yes, and it is the figure people forget. The 68.2 GB above already includes the KV cache at 8K; that cache grows roughly linearly with context, so doubling the window adds real gigabytes rather than a rounding error. If you plan to work with long documents on RTX 5070 12GB, size for the context you will actually use, not the default.
