Officially unveiled last November 2017, Intel has published more information about their partnership with Radeon Technology Group (RTG) to merge the Vega architecture with Intel’s 8th generation processors.

8th Intel Core Processors now powered with Radeon RX Vega M

The new Intel 8th Generation Core processors with Radeon RX Vega M Graphics (also known as Kaby Lake-G) currently has five SKUs: four Core i7s and a single Core i5. These processors are born from a 14nm manufacturing process. The five SKUs are split between Radeon RX Vega M GH (Graphics High) or Radeon RX Vega M GL (Graphics Low). Despite having Vega cores inside, all of these processors still has Intel’s HD 630 integrated graphics. Here are their specifications:

Model Core i7-8809G Core i7-8709G Core i7-8706G Core i7-8705G Core i5-8350G

Integrating Vega

In a move to save power, these Kaby Lake-G processors use the Intel HD 630 inside them to save power when better GPU performance isn’t needed.

Much like their desktop counterparts, these mobile Vega chips uses HBM2 as VRAM for faster operation. These chips also supports AMD’s FreeSync Technology whenever you plug in a FreeSync compatible monitor. Here are the specifications for both the Radeon RX Vega M GH and GL:

Model i7-8809G, i7-8709G i7-8706G, i7-8705G, i5-8305G
GPU Radeon RX Vega M GH Radeon RX Vega GL
Architecture Vega M Vega M
Compute Units 24 20
Stream Processors 1536 1280
Base Clock 1063MHz 931MHz
Boost Clock 1190MHz 1011MHz
Bandwidth 204.8GB/s 179.2GB/s
Peak SP Performance Up to 3.7 TFLOPs Up to 2.6 TFLOPs
ROPs 64 pix/clk 32 pix/clk
High Bandwidth Cache 4GB HBM2 4GB HBM2

Intel has detailed some benchmarks with the official press kit. Until we get our hands on it, however, these would need to be taken with a grain of salt. But based on the initial numbers, the current crop of 8th generation processors with RX Vega M outperforms older gaming laptops with discrete graphics.

We won’t go too much about the technical details until we get hands-on with a device equipped with Intel’s new batch of processors. But it is an exciting time for both low-power devices as well as the mobile world.
