32GB RAM, no graphics card can't get to Llama 3.3 70B Instruct at any price. Here's what actually can.
Llama 3.3 70B Instruct at Q4_K_M needs 45.7 GB once weights, KV cache at 8K context and framework overhead are counted. 32GB RAM, no graphics card offers 0 GB, leaving you 45.7 GB short. 128 GB of unified memory leaves about 96 GB for a model after the OS takes its share, which holds Llama 3.3 70B Instruct 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 3.3 70B Instruct at Q4_K_M.
- Memory is fixed at purchase on these machines — choose the capacity you will still want in three years
- Unified memory: 128 GB, of which roughly 96 GB is usable by a model
- Model requires 45.7 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 3.3 70B Instruct 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
- Add system memory — With no GPU to hold any of the model, more system RAM would let it load but it would run entirely on the CPU — too slow to use for anything interactive. The bottleneck here is the missing GPU, not the memory.

Questions people ask about this pairing
Can a 32GB RAM, no graphics card run Llama 3.3 70B Instruct?
Not as it stands. Llama 3.3 70B Instruct needs 45.7 GB at Q4_K_M and this machine has 0 GB available, a shortfall of 45.7 GB. 128 GB of unified memory leaves about 96 GB for a model after the OS takes its share, which holds Llama 3.3 70B Instruct at Q4_K_M.
Would more system RAM fix this?
With no GPU to hold any of the model, more system RAM would let it load but it would run entirely on the CPU — too slow to use for anything interactive. The bottleneck here is the missing GPU, not the memory.
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 3.3 70B Instruct needs here?
Yes, and it is the figure people forget. The 45.7 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 32GB RAM, no graphics card, size for the context you will actually use, not the default.
