Performance Question: Asus Chromebox vs Fire TV

I have not been able to find any benchmarks in regards to emulation performance that compares the Asus Chromebox vs the Fire TV.

Would anyone have any suggestions on which box would give better performance: to run Lakka on the Asus Chromebox or the RetoArch Android apk on the Fire TV?

ASUS CHROMEBOX-M004U (1.4 GHz Intel Celeron 2955U Processor, 2GB DDR3 RAM, Intel HD graphics)

Amazon Fire TV 2nd Gen 4K Box (MediaTek Quad-core up to 2 Ghz, 2GB RAM, Power VR GX6250 GPU)

I understand there are more PC cores available compared to android, like Reicast and Mednafen Saturn, but I’m not sure if the Chromebox could even run the additional cores at a playable speed.

Did you hear about the udoo x86 ?
