Kaby Lake G (KBL-G) is the name of the core for Intel's high-performance line of mobile processors based on the Kaby Lake microarchitecture and incorporate a discrete AMD Vega graphics processor. These chips are targeted towards ultimate mobile gaming experience. Kaby Lake G processors are fabricated on Intel's enhanced 14nm+ process and for graphics, GlobalFoundries 14 nm process.

Overview

Kaby Lake G based processors are a 2-chip solution - the microprocessor and the chipset. Those parts are BGA and are soldered onto the motherboard. The microprocessor is connected to the chipset via 4 of the chip's 20 PCIe lanes using Intel's proprietary Direct Media Interface 3.0 (DMI 3.0), allowing for 8 GT/s transfer rate per lane.
Graphics
Those processors are unique in the fact that this is the first time Intel has integrated a discrete graphics processor into the same package as the microprocessor. This is also the first time they are using a competitor graphics processor. Those parts incorporate an AMD GPU based on the Vega microarchitecture and incorporate their own 4 GiB of high-bandwidth memory 2 (HBM2). The HBM solution is connected to the graphics processor using Intel's EMIB, a high-speed in-package interconnect solution.
The CPU itself is connected to the GPU using 8 of the other PCIe lanes, leaving the 8 remaining lanes for other peripherals to communicate with the CPU directly.
Common Features
All Kaby Lake G processors have the following:
- Dual-channel Memory
- Up to DDR3L-1600, DDR4-2400
- Up to 64 GiB
- 8x PCIe
- 20x in total, 4 of the 20 are used by the bus and 8 for the GPU as described above
- quad-core with Hyper-Threading (8 threads)
- Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, and AVX2)
- BGA package
Graphics
Those processors have superior graphics capabilities as well as 4 GiB of HBM 2 cache.
