It's based on the Parks LP Core and offers 80 Shader Processing Units, 8 TMUs and 4 ROPs, on 64-bit memory interface of standard GDDR3. The central unit runs at 500MHz and the memory clock operates at up to 800MHz. It consumes no more than 7 Watt.
Its performance is extremely limited and not recommended for any of today's modern demanding games. Crysis 3 and other similar demanding games should be unplayable, even at the lowest settings.
