AMD Radeon RX Vega 56 vs AMD Radeon RX Vega Mobile
AMD Radeon RX Vega 56
AMD Radeon RX Vega 56 is an powerful desktop GPU that first came out on August 31, 2017. It’s based upon the Vega architecture (Vega 10) and is equipped with the fastest HBM2 VRAM. When it first launched in the year 2000, it was the second fastest AMD GPU, and was only beat by RX Vega 64 that was released on the same day. As of the moment of writing the article, both GPUs are now replaced by each of their Radeon VII successors.
This RX Vega 56 reference design includes 56 CUs operating 1 138-1 474 (Boost) MHz (Boost) and 8GB of HBM2 VRAM that runs at 800 MHz and connected via the 2,048-bit memory bus, which results in an overall speed in the range of 409.6 GB/s.

Vega 10 is still produced using a 10-nm process for manufacturing. The die is comprised of around 12.5 billion transistors, and measures 495 mm2 in. The more recent Vega 20 chip, which AMD’s current Radeon VII is based on it, has around 13.2 billion transistors. Applications can access an aggregate of 3,584 shaders. However, the GPU isn’t equipped with those dedicated Raytracing as well as Tensor cores present on Nvidia’s newest RTX series of GPUs.
Performance-wise performance-wise, it’s performance-wise, RX Vega 56 is comparable to the GeForce GTX 1070 from Nvidia which is classified as a middle-class upper. Games that were released in 2018 and in 2019 should perform flawlessly smooth and fine with high-details on WQHD (2560 1440 x 2560).
According to AMD the RX Vega 56’s power consumption maximum is at 210W. With that the GTX 1070’s energy consumption, which is only 150 W that means this Vega 56 cannot keep up with its direct rival with regard to the performance-per-watt ratio.
It is the AMD Radeon Vega Mobile is an exclusive graphics card designed for laptops. It is likely to use the same processor as Kaby-Lake-G’s graphics component. There are rumors that currently talk of 28 CUs (which is 1792 shaders) instead of the 24 CUs used in the top Kaby Lake-G model. The clock speed must be approximately 1 GHz. For graphics memory is concerned, the GPU is likely to also use the 4GB HMB2.
The Vega architecture has some enhancements in comparison to the Polaris generation, and is now compatible with DirectX 12 Feature Level 12_1. More information can be found in our article dedicated to this architecture. Raven Ridge architecture.

The power consumption is similar to that of the Kaby-Lake-G chips (altough it could be more efficient because of the power shared and distributed). The Kaby Lake-G chip is rated at 100W comprising a 35-45 watt processor.
The Radeon Vega was first announced on the day prior to CES at an press conference led by Lisa Su.
