This driver suite will takeover and activate the Hydra 200 chip, which will now function as load balancer in-between the two cards, allowing them to run games. The chip itself is outsourced and manufactured by TSMC on a 65-nm fabrication node, Lucid's Hydra 200 power draw is humble at a rated 6W TDP.Īfter two graphics cards (whether that is ATI or NVIDIA or a combo of them) have been seated you'll need to install the Hydra software driver. Then the midrange LT22102 has a x16 connection to the CPU and two x16 connections for GPUs. The only real difference between the chips are the number of PCIe lanes.Īs such the low-end chip has just one x8 connection to the CPU/PCIe controller and two x8 connections to GPUs. We learned that there are three versions of the Hydra 200 available. That core comes with with 64K of instruction memory and 32K of data memory, both on-chip. Load balancing requires some sort of computational power, and as such the Hyrda chip includes a RISC core (300MHz if I am correct) based on the Tensilica Diamond architecture. The Lucid Hydra chip functions as a load balancer in between two GPUs. First let's have a quick chat about the technology. Lucid's Hydra chip has been a topic of interest for many of us for a long time now, with mixed feelings alright.Ĭan Lucid really design a chip that allows GPU load-balancing that works as smoothly as SLI and CrossFire and then allow mixing GPUs of different types? It's a daunting task for any company, well one thing became abundantly clear, it's not at all as easy as Lucid would like to make us believe. It's time to check a thing or two out about the LUCID Hydra chip used on this motherboard.
