I'm pretty sure they could, lol.
Answering the inevitable mindless "But can it run Crysis?" trolling at work, their Epiphany-III SBC mounted on an 8xPCIe2 card can indeed run Crysis at 2560x1440 "Very High" (x64, 8xAA, DX10) around ~45fps average. Compared to average of ~48fps on GTX680, ~50fps on HD7970, ~54fps on GTX780Ti, ~70fps on RX580, ~77fps on GTX980Ti.
They're currently trying to fit two Epiphany-III SBCs onto an 8xPCIe3 card.
Their ultimate goal is to mount four Epiphany-III SBCs on a 16xPCIe3 card. An emulated GPU running ~20W, costing ~$650, without reliance on crappy AMD or NVIDIA drivers.
So yeah, it is actually kind of exciting, lol. And they're not even working with Epiphany-IV, let alone Epiphany-V.
