Sure, you could transform your Ultrabook into a gaming notebook, but eGPUs are expensive, aren’t portable, and are clunky to set up. Personally, I was never a fan of this design. While you could never get desktop-class performance from these enclosures, they seemed like a great way to augment your existing laptop’s performance. The Thunderbolt interface used by eGPUs, on the other hand, only offers 4x PCIe lanes at best, and half that number if your eGPU is driving your laptop’s internal display. Depending on the GPU you’re using, 8 lanes will also do, with the performance hit on medium to high-end GPUs being limited to a few percentage points. Image: Anirudh RegidiĪ GPU normally connects to your PC via an interface called PCIe, and it needs 16 PCIe data lanes to perform at its best. Either way, Haas very clearly states that the large market appeal of affordable external GPUs is just his opinion, though we’re going to assume his opinion holds a bit of water in Santa Clara.XG Mobile is hardly larger than a book, making it one of the smallest eGPU docks around. We assume he is referring to AMD’s ATI XGP box (or Fujitsu Siemens’s Lasso) which is the only one available - the ASUS XG station (pictured above) that seemed to vanish into thin air after its brief appearance at CES 2008. Manager of notebook GPUs Rene Haas told X-bit Labs that he thinks external graphics adapters for laptops are a “big opportunity” for NVIDIA, though he noted the drawback of their high price tags. It’s not everyday that we can say there’s external laptop GPU love in the air, but right on the heels the appearance of the Gigabyte M1405 with its GeForce GT220 dock, NVIDIA is expressing interest in external laptop GPUs as well. said that it considers external graphics adapters for notebooks a big opportunity even though the company does not offer such products at the moment. We continue to look at whether this is a GPU or external devices,” said Rene Haas, general manager of the notebook GPU business at Nvidia, in a brief interview with X-bit labs.Ī high-ranking executive from Nvidia Corporation. I think there is definitely a place for, no question. We have two strategies at Nvidia: one is to put graphics everywhere, the other one is to integrate discrete chips into the box.
