R9700 vs Arc Pro B70: which is better for local AI?
32GB against 32GB, 640 against 608 GB/s. What each runs, how fast, and which one to buy.
The verdict
Both have 32GB of memory, so they run the same models. The R9700 generates text about 25% faster thanks to 640 GB/s of memory bandwidth versus 608 GB/s. The Arc Pro B70 costs about $500 less ($1,300 vs $1,800).
- Get the R9700 if speed matters most.
- Get the Arc Pro B70 if you want the most for your money or you care about power draw, heat, and noise.

Our take
Bottom line on each
32GB for far less than NVIDIA workstation cards and built for stacking, but no faster per card than an RX 9070 XT.
32GB of new VRAM for well under NVIDIA or R9700 prices, held back by Intel's maturing software.
Frequently asked questions
Is the R9700 or Arc Pro B70 better for running LLMs?
Both have 32GB of memory, so they run the same models. The R9700 generates text about 25% faster thanks to 640 GB/s of memory bandwidth versus 608 GB/s. The Arc Pro B70 costs about $500 less ($1,300 vs $1,800).
How much faster is the R9700 than the Arc Pro B70 for AI?
About 25% faster at generating text in our estimates, because token generation is limited by memory bandwidth (640 GB/s vs 608 GB/s). Prompt processing depends more on compute and can differ by more.
