The AMD Radeon Vega Mobile is a dedicated graphics card for laptops. It most likely uses the same chip as the Kaby-Lake-G graphics part. Rumors currently speak of 28 CUs (= 1792 shaders) instead of the 24 CUs in the Kaby-Lake-G top model. The clock speed should be also around 1 GHz. As graphics memory, the GPU most likely also uses 4 GB HMB2.
The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. More information is available in our dedicated article about the Raven Ridge architecture.
The power consumption should be similar to the Kaby-Lake-G chips (altough this may be more efficient due to power sharing and distribution). The Kaby-Lake-G is rated at 100 Watt including a 35-45 Watt processor.
AMD’s Radeon RX Vega 56 is a high-end desktop GPU that was first introduced in August of 2017. It is based on the Vega architecture (Vega 10) and equipped with fast HBM2 VRAM. When it was first introduced, it was the second fastest AMD GPU available, only bested by the RX Vega 64 that launched on the very same day. At the time of writing, both GPUs have been replaced by their respective Radeon VII successors.
The RX Vega 56 reference design features 56 CUs running at 1,138-1,474 MHz (Boost) and 8 GB of HBM2 VRAM running at 800 MHz connected via a 2,048-bit memory bus resulting in a memory bandwidth of 409.6 GB/s.
Vega 10 is still produced in a 10-nm manufacturing process. The die consists of roughly 12.5 billion transistors and measures 495 mm2 in size. The newer Vega 20 chip, which AMD’s current Radeon VII is based on, features around 13.2 billion transistors. Applications have access to a total of 3,584 shaders, but the GPU lacks the dedicated Raytracing and Tensor cores that can be found on Nvidia’s latest RTX generation of GPUs.
Performance-wise, the RX Vega 56 is comparable to an Nvidia GeForce GTX 1070, and thus best categorized as upper middle-class. Games released in 2018 and 2019 should run perfectly fine and smooth in high details on WQHD (2560 x 1440).
According to AMD, the RX Vega 56’s maximum power consumption is 210 W. Given the GTX 1070’s power consumption of just 150 W, the Vega 56 cannot keep up with its direct competitor in regards to performance-per-watt ratio.
The AMD Radeon RX Vega M GL or Radeon RX Vega 870 (according to Dell) is an integrated GPU in the slower Intel Kaby-Lake-G SoC. It combines a Kaby-Lake processor, a Vega graphics card and 4 GB HBM2 memory on a single package. The graphics card offers 20 CUs (1280 shaders) and is clocked from 931 - 1011 MHz.
Currently it looks like the GPU is a mixture of Polaris (Shaders?) and Vega (HBM memory controller at least). E.g. the graphics card is called Polaris 22 internally. Detailed information on the Vega architecture can be found in our dedicated article about the Raven Ridge architecture.
The performance of the Vega M GL should be between the Nvidia GeForce GTX 1050 and 1050 Ti according to benchmarks from Intel. Therefore, it should be well suited for 1080p and high resolution gaming.
The power consumption should be quite similar to a dedicated Vega Mobile GPU, but due to the small form factor, smaller laptops can be built with the Kaby-Lake-G SoC. The TDP is specified at 65 Watt for the whole package including GPU, CPU and HBM2 memory.
