AMD Radeon RX Vega 56 vs AMD Radeon RX Vega 7 vs AMD Radeon RX Vega 64

AMD Radeon RX Vega 56

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 64

The AMD Radeon RX Vega 64 is a high-end desktop graphics card that was announced in August 2017. It uses the Vega 10 chip and is the top model of the AMD desktop graphics cards (through 2018). It offers 64 CUs clocked at 1247 - 1546 MHz (Boost) and 8 GB HBM2 graphics memory. In games, the Vega 64 offers a similar performance as a Nvidia GeForce GTX 1080 on average.
