AMD Radeon RX Vega 7 vs NVIDIA GeForce GTX 1070 Ti (Desktop)

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.

NVIDIA GeForce GTX 1070 Ti (Desktop)

The Nvidia GeForce GTX 1070 Ti is the second fastest Pascal based graphics card in November 2017. It is a high-end desktop graphics card based on a cut down GP104 chip as the GTX 1080 and manufactured in 16 nm FinFET at TSMC. Compared to the GTX 1080, it uses the more available GDDR5 graphics memory, and compared to the GTX 1070 it offers more shaders (2432 versus 1920). More details on the Pascal architecture including all features and comparisons to Maxwell, can be found here.

The performance of the GTX 1070 Ti was in our tests right between the GTX 1070 and GTX 1080. However, the powerefficiency was worse than the GTX 1070 and near the GTX 1080. Nvidia also specifies the 1070 Ti and 1080 at 180W.
