AMD Radeon RX Vega 56 vs AMD Radeon RX Vega 6 (Ryzen 4000)
AMD Radeon RX Vega 56► remove
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 At the time of writing, both GPUs have been replaced by their respective Radeon VII successors.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.
AMD Radeon RX Vega 6 (Ryzen 4000)► remove
The AMD Radeon RX Vega 6 is an integrated GPU for notebooks. It is used in the Ryzen 5 APUs of the Renoir generation (Ryzen 4000 Mobile), which were launched in early 2020. The GPU is based on the Vega architecture (5th generation GCN) and has 6 CUs (= 384 of the 704 shaders) clocked at up to 1.500 MHz. Compared to the similar Radeon RX Vega 6 in the Raven Ridge generation (Ryzen 2000 Mobile), the GPU is clocked significantly higher (1.500 versus 1.100 MHz Boost).
The performance depends on the configured TDP (12-54 W at launch), the clocks, the cooling, and the memory configuration). The GPU should benefit from fast dual-channel DDR4-3200 RAM (contrary to DDR4-2133 single-channel, which is also possible).
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 performance is clearly faster than the old RX Vega 6 thanks to the higher clock speed and faster main memory (if used). In first synthetic benchmarks, the Vega 6 was able to reach the performance of a dedicated GeForce MX150. In games it should be somewhere between a GeForce MX230 and MX150.
Thanks to the modern 7nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics card can also be used for slim and light notebooks.
