AMD Strato PRO, Litho XT GPUs spotted, could be AMD's new MXM series

The last rumor we had to report on about AMD was the exciting new HBM-based, 4096-bit wide memory bus Radeon R9 390X, but now we're going to tell you a little about the lower-end cards that will most likely find their way to consumers in the first half of 2015.

These new cards will reportedly be AMD's new MXM-based GPUs, arriving as the Litho XT and Strato PRO. These two new mystery cards have just reached Zauba.com, with the Litho and Strato most likely standing for the space-driven names of Lithosphere and Stratosphere. Starting with the Litho XT, which will be a Type A MXM GPU with 2GB of GDDR5 memory, while the bigger Strato PRO will be a Type B MXM GPU with 4GB of RAM.

The XT side of things will be the powerful card, while the PRO will have a cut die. We could also see a Strato XT in the future, but we won't know anything until the new rumors start floating online.
