AMD Radeon RX Vega 8 (Ryzen 4000)
The AMD Radeon RX Vega 8 is an integrated GPU for notebooks. It is used for the Ryzen 7 APUs of the Renoir generation (Ryzen 4000 Mobile), which were announced in early 2020. The GPU is based on the Vega architecture (5th generation GCN) and has 8 CUs (= 512 of the 704 shaders) clocked at up to 1.750 MHz (Ryzen 7 4800U). The performance depends on the configured TDP (12-25 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). Compared to the similar Radeon RX Vega 8 in the Raven Ridge generation (Ryzen 2000 Mobile), the GPU is clocked significantly higher (1.750 versus 1.100 MHz Boost, +59%).
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 8 thanks to the higher clock speed and faster main memory (if used). Still it is positioned in the entry level (compared to dedicated graphics cards) and only suited for low demanding games.
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.
