This iPad Pro + Thunderbolt R9700 is running Qwen3.8-27B at 158.5 tps.
Yes… an iPad.
The trick
🎮 32GB Radeon AI PRO R9700
🔌 Thunderbolt eGPU enclosure
📱 iPad Pro running LemonSeed Studio
🧠 Qwen3.8-27B Q4
📚 131K context
And the speed progression is kind of ridiculous
🐌 baseline → 31.2 tps
⚡ MTP3 → 108.7 tps
🚀 DFlash2 → 158.5 tps
Prefill:
📥 4K → 1,636 tps
📥 32K → 1,395 tps
LemonSeed actually runs the AMD GPU on iPadOS.
It embeds the upstream Linux amdgpu + amdkfd driver as an iPad PCIDriverKit extension, then runs its inference engine on the R9700.
Same engine for 🐧 Linux | 🍎 macOS | 📱 iPadOS
Same R9700 on macOS reaches 159.4 tps, so the iPadOS result is basically right there with the Mac.
⚠️ Obviously, the iPad's own GPU isn't doing the 159 tps.
The iPad is hosting a 32GB desktop AMD GPU over Thunderbolt.
