AMD Radeon RX Vega 11 vs NVIDIA GeForce GTX 1070 Ti (Desktop) vs NVIDIA GeForce GTX 1080 Ti (Desktop)

AMD Radeon RX Vega 11

The AMD Radeon RX Vega 11 is an integrated GPU in the Ryzen desktop APUs (e.g. Ryzen 5 2400G) that were launched early 2018. The graphics card is based on the Vega architecture (5th generation GCN) and has all 11 CUs (=704 shaders) clocked at up to 1240 MHz (Ryzen 5 2400G). The GPU benefits from fast dual-channel DDR4-2400 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.

According to a first 3DMark Fire Strike that was published by AMD, the Vega 11 offers a similiar theoretical performance as the older dedicated Radeon R9 M280X. In games the missing dedicated graphics memory may however prove to be a bottleneck. Therefore, modern and demanding games will only be playable in lowest settings and the APU is mostly intended for lower demanding games like Overwatch, Dota 2, ...

Thanks to the 14nm process and clever power-saving features, the power consumption is comparatively low. The high TDP of 65 Watt of the APU however should lead to a much higher power consumption compared to the mobile APUs with 15 Watt TDP.

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.

NVIDIA GeForce GTX 1080 Ti (Desktop)

The Nvidia GeForce GTX 1080 Ti is the fastest desktop consumer graphics card (beginning 2017). It is based on the same GP107 chip as the Titan X but with slightly higher clock speeds and a different memory configuration. It offers one memory controller less (and 11 instead of 12 GB), but the GDDR5X memory is faster clocked (11 GHz) leading to a comparable memory bandwidth. Due to the higher boost clock, the 1080Ti should be around 5 % faster compared to the Pascal Titan X and about 35 % faster compared to the GTX 1080. The TDP is equal to the Titan X with 250 Watt. A new cooler of the Founders Edition should be more efficient and quieter.
