AMD Radeon RX Vega 7 vs AMD Radeon RX Vega Mobile vs AMD Radeon RX Vega 6 (Ryzen 4000/5000)

AMD Radeon RX Vega 7

The AMD Radeon RX Vega 7 is an integrated GPU for notebooks. It is used in the Ryzen 4000 and Ryzen 5000 mobile APUs. The GPU is based on the Vega architecture (5th generation GCN) and has 7 CUs (= 448 shaders) clocked at up to 1,800 MHz. The iGPU's performance depends on the TDP of an APU (15, 35, 45 W or cTDP), 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 should be slightly lower than the older RX Vega 8 GPU (1 CU more, but lower clock speed). That means, only some demanding games of 2019 will run in lowest detail settings. Less demanding games like Fifa 20 or Dirt Rally 2.0 should run in higher settings and 1920 x 1080.

Thanks to the 7 nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the iGPU won't look out of place in a slimmer, lighter laptop.

AMD Radeon RX Vega Mobile

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 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.

The Radeon Vega Mobile was announced one day before CES at a press event by Lisa Su. 

AMD Radeon RX Vega 6 (Ryzen 4000/5000)

The AMD Radeon RX Vega 6 is an integrated GPU for notebooks. It is used in certain Ryzen 5 APUs of the Renoir generation (Ryzen 4000 Mobile), which were launched in early 2020. The iGPU is based on the Vega architecture (5th generation GCN) and has 6 CUs (= 384 of the 512 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 adapter can also be used for slim and light notebooks.
