At this time we don’t have many more details, but this would be the first consumer-based implementation of the HYDRA chip that offers hardware-agnostic multi-GPU support with SUPPOSED near-linear scaling. Since we first talked with the developers of the technology in 2008, we really haven’t heard much from them and seeing an implementation like this so suddenly is kind of surprising.
According to the source, all of three of the PCIe x16 slots on this board connect to the HYDRA controller chip in order to allow for the multi-GPU scaling technology to work. There is no indication of actual PCIe bandwidth configurations or where the HYDRA chip actually communicates with the system: through the P55 chipset or directly to the CPU’s integrated PCI Express channels.
We have put in questions to the appropriate people and will update you with anything we find!! You can look through ALL of our Lucid HYDRA chip coverage here in our search engine.
