Elpis is an 80nm GPU specifically made for retrofitting faulty Xenon motherboards. Once retrofitted, the motherboard is also referred to as Elpis. The Elpis GPU was created by slightly modifying the fixed (higher Tg) version of the Rhea GPU.

Details
The only known change from Rhea to create Elpis was swizzling (flipping) the PCIe balls on the chip in order to match the ballout of the original 90nm Y1 chip it replaces. Like Rhea, it uses the Styx-90 eDRAM. These chips are known to be reliable.
