Llama 3.3 70B
Hardware requirement
EstimatedRunning Llama 3.3 70B as Q4_K_M in Ollama at ~8,192 tokens of context.
How this is calculated
|
Model weights
derived
|
40.9 GB | 70.554 billion parameters × 0.58 bytes/param (Q4_K_M) ≈ 40.9 GB. |
|
KV cache (context memory)
derived
|
2.7 GB | 8,192 tokens × 80 layers × 2 × 8 KV heads × 128 head dim × 2 bytes ≈ 2.7 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
|
44.6 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
|
64 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 We do not publish tokens-per-second figures because we have no measured source for them.

Graphics CardPNY VCQRTX8000-PB$3,297
This model needs about 45 GB of VRAM under lean settings. The PNY VCQRTX8000-PB (48 GB) is the most affordable card that holds the whole model on the GPU.
-
ProcessorAMD Ryzen 5 7500F$0
Local AI inference runs on the GPU, so a capable budget CPU like the AMD Ryzen 5 7500F keeps costs down without holding the model back.
-
MotherboardAsus TUF GAMING B650M-E WIFI$0
Matches the CPU socket (AM5) and DDR5 memory; a solid value board with room to expand.
-
MemoryG.Skill Trident Z5 RGB 64 GB$225
This model wants about 64 GB of system RAM; the 64 GB DDR5 kit covers it with headroom for the OS and offload.
-
StorageCrucial P3 Plus$62
1 TB of NVMe — local model files are large (tens of GB each), and NVMe keeps load times short.
-
CPU CoolerNZXT Kraken Elite 360 RGB$0
Keeps the CPU cool and quiet under sustained load; compatible with the chosen socket.
-
Power SupplyCooler Master G800$0
Estimated system draw is about 555 W; the 800 W unit leaves headroom for GPU power spikes and efficiency.
-
CaseDeepcool CH160$0
Fits the motherboard form factor and has clearance for the graphics card ( mm).
