Benchmarks

How to read a local-AI speed number on Radeon, then the handful of figures we actually ran on wtpai1. Nothing here is a scraped leaderboard. If a cell is empty we write not measured.

How to read a bench

pp vs tg

Prefill and decode

llama.cpp’s llama-bench prints pp(prompt processing / prefill) and tg(token generation / decode). Prefill is how fast the prompt is ingested. Decode is how fast new tokens appear — the number people mean by “tok/s” in chat. Every first-party figure on this page is tgunless a column says otherwise.

Short vs long

Context length changes the number

Short context is a small prompt — the happy path. At 32K and 256K the KV cache is larger, the card works harder, and decode drops. Comparing a 4K blog number to a 262K daily driver is a category error.

Where the weights live

VRAM, RAM, and offload

Tokens stay fast when the whole file and its KV sit in one GPU. Spill into system RAM and decode falls off a cliff. Our 35B daily driver is 0% RAM offload on one 32 GB card. Flash Q6 is a much larger file — expect RAM to hold most of it. Fit check:calculator.

The runtime

Engine is not optional

The same GGUF on llama.cpp and Strata is two different programs. Consumer default is llama.cpp(Vulkan on this 35B). Strata is the Flash try we measured. A score without engine, quant, context, KV type, and gfx is not a score.

Our test rig

Green numbers on this site come from wtpai1. Source note:wtpai1 strata-test report / Local AI measurements. If we did not run it, we do not print a tok/s.

None on this page

We would rather omit a third-party table than paste an unverified leaderboard. Official docs below are for words (pp/tg, model cards, the SKU) — not for someone else’s tok/s.

Two AMD Radeon AI PRO R9700 (32 GB GDDR6, gfx1201). 256 GB DDR5. Daily-driver and 35B rows use ONE card. The second card is there; do not assume a split.

How to reproduce

  1. Stack Lab — Benchmark my rig (upcoming).The Ubuntu companion will grow a flow that records model, quant, context, engine, gfx, and tok/s without inventing a number. It is not shipping in this snapshot. Map of the profiles:Radeon Stack Lab.
  2. llama.cpp on one R9700.Daily-driver shape is Vulkan, UD-Q5_K_XL, 262144, f16 KV, 0% offload. Compile and serve notes:llama.cpp. Exact flags stay TODO on stacks.
  3. Strata for Flash Q6.v0.1.42, recipe strata-flash-q6, no MTP, 262K.Strata. Do not treat this as a HIP-versus-Vulkan verdict.
  4. No fake third-party scores.If you post a number in theforum, include model, quant, context, engine, gfx, and KV type. A screenshot without those is not a bench.
