Number Crunching Gymnastics

GPUs aren’t just for gaming, editing, and media – they’re also built for significant data crunching. The OWC Mercury Helios FX chassis makes it easy to add exponentially faster GPU-accelerated performance for data science, forecasting, modeling, mining, engineering, big data, and image analytics rigs.


Owners of laptops that serve double-duty as a remote and desktop workstation no longer need to settle for mere "laptop quality" GPUs. Simply plug the Mercury Helios FX with the compatible GPU of your choice into your Thunderbolt 3-equipped laptop and experience exhilarating desktop-class graphics performance with the bandwidth to support multiple displays.

With the Mercury Helios FX and your favorite compatible GPU your arsenal, you no longer need a large gaming laptop. You can instead opt for a lighter laptop, and when you don’t need the added Mercury Helios FX eGPU horsepower, simply disconnect the Thunderbolt 3 cable to leave the weight behind. And when a newer, faster, and better GPU comes out, or when new software and games demand more GPU prowess — you can easily swap out the GPU versus buying a completely new laptop. How’s that for versatility?


With its Thunderbolt 3 interface, you can simply add your eGPU juggernaut to whatever computer needs a boost. Whether it’s a Mac or Windows PC, plug Mercury Helios FX and the compatible GPU of your choice in with the included Thunderbolt 3 cable to experience an exhilarating performance boost.
