Exact quantized file bytes + FP16 KV cache + 2 GiB reserved for the runtime. KV bytes = 2 × layers × KV heads × head dimension × total context tokens × 2 bytes. 1 GiB = 2³⁰ bytes.
Nominal manufacturer GB labels use a conservative decimal-GB budget (1 GB = 10⁹ bytes). Actual free VRAM, engine allocation, driver and operating-system support must be checked. Passing this estimate does not establish a tested deployment or the largest model the card could run. CPU offload, multi-GPU and training are outside this calculation.

How fast does it generate tokens?
No sourced speed test collected yet.
Memory fit can help shortlist GeForce RTX 5070, but it does not establish output tokens per second. Validate your chosen model, quantization and engine before budgeting around its speed.
The context selector above changes memory estimates only. Published speed records keep their original model and test conditions; these are external reports, not our measurements.

This is the matching evidence currently in our catalog. It is not a complete provider comparison or a market-wide lowest-price claim.
Hardware identity & sources.
Chip designer: NVIDIA. Desktop RTX 5070; not the 5070 Ti or laptop variant. Retail board brands, seller SKUs and regional availability need their own evidence.
Model files and pinned revisions are attached to each memory estimate. Speed and price records link to their sources above. Rebuilding this page does not refresh those observation dates.
