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.

Preliminary Data! Information presented in this article deal with future products, data, features, and specifications that have yet to be finalized, announced, or released. Information may be incomplete and can change by final release.

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)

Graphics

Those processors have superior graphics capabilities as well as 4 GiB of HBM 2 cache.
