Description

> # Community benchmark on NVIDIA GeForce RTX 5070 Ti
> 
> Measured on 2026-10-16 with `tools/strata_bench.py` (suite 1, 3 runs per test, medians with ranges). Speeds are the engine's own timings; first-token times are measured by the client over HTTP. Speed only: no correctness check was run.
> 
> ## Hardware and software
> 
> - GPU and VRAM: NVIDIA GeForce RTX 5070 Ti, 16 GiB VRAM
> - CPU: 13th Gen Intel(R) Core(TM) i5-13600KF (14 cores, 20 threads); installed RAM: 63.8 GiB; storage: not measured
> - OS: Windows 10 (10.0.19045); GPU driver: not read; CUDA: not read
> - Strata: project 0.1.43.1, commit not a git checkout; engine 0.1.43.1
> - Background workloads and power limits: not recorded
> 
> ## Model and configuration
> 
> - Model and quantization: qwen3.8-flash-next-iq3_s
> - Context: 262144 tokens; parallel slots: 1
> - Settings: the install's own configuration, unchanged; thinking off for the suite; temperature 0
> 
> ## Method
> 
> Run by `python tools/strata_bench.py` against the HTTP API of a Strata server (already running); model loading is not timed. One warm-up chat and a 1K prompt are discarded first. Every prompt starts with a unique tag, so the conversation cache cannot help the fresh-prompt tests.
> 
> - short chat: the three questions of `tools/ab_engine.py`, up to 100 new tokens, 3 runs
> - 4K / 16K prompts: generated word lists sized by a calibration request, 24 new tokens, 3 fresh prompts each
> - agent session: system prompt and four tools, then 5 turns that each add about 1500 words of a project file and continue from the model's own earlier answers (the way agent clients resend a conversation), 64 new tokens per turn, 3 sessions; the cache numbers come from the answer's usage (`cached_tokens`) and timings (`prompt_n`)
> - concurrency (when run): N requests sent at the same moment, total tokens over the wall time of the burst, latency over all requests
> 
> ## Results
> 
> | Configuration | Actual prompt tokens | Reused tokens | Generated tokens | Runs | Prompt tok/s median and range | Decode tok/s median and range | TTFT seconds median and range |
> | --- | ---: | ---: | ---: | ---: | --- | --- | --- |
> | short chat | 46 (43-51) | 0 | 100 (100-100) | 9 | not measured | 38.1 (32.6-42.9) | 0.95 (0.83-1.04) |
> | 4K prompt, fresh | 4019 (4019-4019) | 0 (0-0) | 24 cap | 3 | 931.9 (857.1-947.8) | not measured | 4.36 (4.28-4.73) |
> | 16K prompt, fresh | 16058 (16058-16058) | 0 (0-0) | 24 cap | 3 | 1199.6 (1198.5-1204.8) | not measured | 13.44 (13.38-13.47) |
> | agent session, follow-up turns | 14487 (14440-14504) at the last turn | see below | up to 64 | 3 | see below | 42.2 (34.8-54.9) | 3.94 (3.60-4.14) |
> 
> Ranges are the lowest and highest of the runs; `Runs` counts requests that returned a token.
> 
> ### Agent session (conversation cache)
> 
> Cache hit over the follow-up turns: 68.5 % (68.5-68.8); earlier-turn tokens read again per session: 144 (4-144) (earlier turns that the cache did not hold; the 13634 (13634-13635) new tokens of the files are read once); first turn (nothing cached) first token: 2.51 s (2.49-2.52).
> 
> | Turn (run 1) | Prompt tokens | Reused | Read | Prompt tok/s | First token (s) | Decode tok/s |

> 
> ## Correctness and limitations
> 
> Not measured: this is a speed suite. The conversation uses the model's own replies, so token counts differ a little between runs. Machine details come from the server, `nvidia-smi`/`rocm-smi` and the OS; background load and power limits are not recorded. Total time of the suite: 183 s.
