Just ran llama-bench at home with the similar priced AMD AI PRO R9700 32G. The phoronix numbers look extremely low? Probably I misunderstand their test bench. Anyway, here are some numbers. Maybe someone with access to a B70 can post a comparison.

Tried to use the same model as the article:

llama-bench -m gpt-oss-20b-Q8_0.gguf -ngl 999 -p 2048 -n 128

AMD R9700 pp2048=3867 tg128=175

And a bigger model, because testing a tiny model with a 32GB card feels like a waste:

llama-bench -m Qwen3.6-27B-UD-Q6_K_XL.gguf -ngl 999 -p 2048 -n 128

AMD R9700 pp2048=917 tg128=22

Also from phoronix, a comparison with AMD R9700 and RTX 6000 Ada (because Nvidia has not sent them a blackwell card): https://www.phoronix.com/review/intel-arc-pro-b70/2
