The formula for this estimate.
Weights GiB = exact recorded file bytes / 2^30. KV GiB = 2 × layers × KV heads × head dimension × context × KV bytes / 2^30. Required GiB = weights + KV + runtime overhead. Usable GiB = device GiB × usable fraction. Estimated decode tokens/s = bandwidth GB/s × 10^9 / (active parameters B × 10^9 × effective bytes per weight) × efficiency. Effective bytes per weight = file bytes / (total parameters B × 10^9). Selected efficiency = 0.6; sensitivity uses 0.4–0.8.
Assumptions and limitations
- Memory values labeled GB in the data contract are GiB (2^30 bytes); bandwidth uses decimal GB/s (10^9 bytes/s).
- The memory budget reserves 25.0% of device memory. Runtime overhead is an assumed 1 GiB.
- KV cache assumes 2 bytes per element, independently of weight quantization. Runtime cache layout and allocation can add memory.
- Memory fit does not establish runtime, driver, operating-system, architecture, or quantization support.
- All speed values are estimated single-stream decode proxies, not benchmarks. Prefill, batching, latency, and concurrent sessions are not predicted.
- Estimated speed sensitivity is not a confidence interval; actual speed can fall outside the range because of compute, cache traffic, kernels, thermal limits, and other workloads.
- Effective bytes per weight is the exact file-size / total-parameter proxy. Metadata, tensors with different precision, padding, and duplicated tensors make it different from nominal quantization bits.
