RTX 4080 16GB is a consumer accelerator from NVIDIA with 16 GB of VRAM and 717 GB/s of memory bandwidth, typically around $0.3/hr on cloud rental. It is aimed at local inference and development.
3 models in the tokcalc catalog fit on one RTX 4080 16GB, up to BGE-M3 (embed, 1024-dim) (1B params) at fp16. Below that, throughput and cost per million tokens improve as the model gets smaller.
At fp8 with 8 concurrent users, 8× RTX 4080 16GB serves 6464 tokens/sec aggregate (67.33 tok/s per stream), with a 5.98 s time to first token. That works out to $0.1031 per 1M output tokens.
Around $0.3/hr for on-demand cloud rental (a typical 2025–2026 estimate across RunPod, Lambda, Modal, AWS, GCP and similar providers). Actual pricing varies by region, commitment, and spot availability — the Build vs Buy tab in the calculator pulls live quotes from several providers.
Memory bandwidth drives decode speed and VRAM drives capacity. RTX 4080 16GB has 717 GB/s of bandwidth and 16 GB of VRAM, plus 48.7 TFLOPS of dense FP16/BF16 compute. The comparison table on this page ranks every accelerator in the catalog on the same reference workload so you can see where it lands.
Pick your model, context length, and concurrency — the calculator computes the rest with the same formulas.
