Intel and AMD ally to shrink your next gaming laptop. A lot.

In fall 2017, chipmaking rivals Intel and AMD made a splash when they announced a low(er)-power processor combining Intel's eighth-generation series of Core i H-series CPUs with AMD Radeon RX Vega M discrete graphics. They didn't offer much in the way of details at the time, and at CES 2018 Intel followed up with specifics and more. The new "G" line targets the same gamers and content creators that systems based on Nvidia's Max-Q mobile GeForce GPUs do; people who need smaller, lighter laptops that punch way above their weight, such as supporting VR.

The Gs combine the Core i H-series CPUs with a custom version of the Radeon GPU in much the same way AMD's own Ryzen 2500U and 2700U do. Because Intel doesn't use AMD's Infinity Fabric technology, which allows AMD to mesh its modular die architectures together, Intel developed its own Embedded Multi-Die Interconnect Bridge (EMIB) to connect the CPU with the high-bandwidth memory (HBM2) AMD uses with its GPUs. The packages are much smaller than previous offerings and use less power, enabling smaller devices that deliver the same performance as larger predecessors.

Intel initially plans two different tiers of processors, which will come in Core i5 and i7 versions, based on the target power requirements of the systems. The Core processor with RX Vega M GL ("graphics low") is designed for thin and light systems in which the total power draw of the package doesn't exceed 65 watts (we'll see models from Dell and HP at the show). These will be the Core i7-8706G, i7-8705G and i5-8305G and incorporate a 20 compute-unit version of the Vega.

The other tier is designed for systems that can handle a power draw of 100 watts: compact desktops and all-in-ones, for example, or what Intel refers to as 1.2-liter systems (73 cubic inches). The HP Omen X Compact Desktop, the VR backpack, is about 234 cubic inches in comparison.
