The unit's 10.1-inch screen will boast a pixel density higher than Apple's third-generation iPad, Richard Shim, an analyst at NPD DisplaySearch, told CNET.
The display will have pixels-per-inch number of about 299, topping the 264 PPI on the 9.7-inch Retina iPad, he said.
The partnership with Samsung is a significant broadening of Google's relationship with the South Korean company.
Google already cobrands the Galaxy Nexus Samsung smartphone.
Although there's no word on a possible price point, Shim says it will probably be in iPad territory.
"It's going to be a high-end device," Shim said in contrast to Google's current $199 Nexus 7.
Information about the 10.1-inch Nexus comes from "supply chain indications," which typically indicate a high likelihood a product will be produced, Shim said.
