AMD Radeon RX Vega M GH vs AMD Radeon RX Vega 56
AMD Radeon RX Vega M GH► remove from comparison
The AMD Radeon RX Vega M GH is an integrated GPU in the fastest 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 24 CUs (1536 shaders) and is clocked from 1063 - 1190 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 GH should be slightly slower than a dedicated Nvidia GeForce GTX 1060 for laptops 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.
AMD Radeon RX Vega 56► remove from comparison
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 At the time of writing, both GPUs have been replaced by their respective Radeon VII successors.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.
