Radeon RX Vega 56 and GeForce GTX 1070 are high-end graphics cards from AMD and Nvidia respectively. Both these graphics cards falls in the same segment whether it their price or gaming performance. Radeon RX Vega 56 is a much newer card while GeForce GTX 1070 was around for a while and is a time tested card that really holds its ground.
There was no graphics card from AMD to challenge GeForce GTX 1070 because their top-end Polaris card i.e. Radeon RX 580 was only good enough for GeForce GTX 1060. But now things are going to change as Radeon RX Vega 56 is here to trouble GeForce GTX 1070 and will make the completion very fierce. Here I am going to compare both these high-end graphics cards so that you can make clear decision on which graphics card suits you the best.

RX Vega 56 vs GTX 1070 Comparison
Here is a detailed comparison of Radeon RX Vega 56 and GeForce GTX 1070 graphics cars based on their specifications, features, performance and power consumption.
Radeon RX Vega 56 is built on the latest Vega architecture from AMD and comes with 3584 Stream Processors. Vega is the latest GPU architecture from AMD for high performance graphics cards whether gaming or workstation graphics cards.
On the other hand GeForce GTX 1070 uses Pascal GPU architecture that is used in GeForce 10 series graphics cards. GeForce GTX 1070 has got 1920 CUDA Cores which may seems a lot less than RX Vega 56 but we cannot compare Stream Processors to CUDA Cores because of the difference in their architecture.

Radeon RX Vega 56 comes with 8GB HBM2 memory which is a high bandwidth next generation memory used for VR and in high-end hardware. HBM2 is much faster than the GDDR5 memory which GeForce GTX 1070 uses. The memory interface here is 2048-bit and bandwidth is whopping 410 MB/s.
GeForce GTX 1070 comes with 8GB GDDR5 having 256-bit interface and memory bandwidth of 256 GB/s. As you can see that memory bandwidth of GeForce GTX 1070 is almost half of Radeon RX 56 and this can make some performance difference in gaming especially at higher resolutions. So in terms in memory performance, Radeon RX Vega 56 wins easily.
Both these graphics cards support DirectX 12, OpenGL 4.5 and Vulkan APIs for latest games. Also both these graphics cards comes with their own variable refresh rate technologies to prevent screen tearing and stuttering in games. In Radeon RX Vega 56 it is called FreeSync 2 and GeForce GTX 1070 has G-Sync. Both these graphics cards are VR Ready and support multi-GPU technology for increasing the performance. Radeon RX Vega 56 has CrossFire and Geforce GTX 1070 supports SLI multi-GPU technology.
Performance (Gaming & Other)
Both these graphics cards are very close to each other in gaming performance. Radeon RX Vega 56 performs a bit better than GeForce GTX 1070 especially in Vulkan titles. When it comes to compute performance, then Radeon RX Vega 56 is way ahead as it has compute performance of 10.5 TFLOPS whereas GeForce GTX 1070 stands at 6.46 TFLOPS only. This also makes Radeon RX Vega 56 a better card for cryptocurrency mining purpose.
When it comes to power consumption then GeForce GTX 1070 wins hands down. GeForce GTX 1070 has maximum power consumption of 150W and requires 500W PSU whereas Radeon RX Vega 56 has TDP of 210W which is considerably higher and needs minimum of 650W PSU.
Both these graphics cards falls in the same price range and their prices may different according the cooling solution used and graphics card manufacturer. However, you will find price of Radeon RX Vega 56 a bit higher than the GeForce GTX 1070. You may check the latest prices of both these graphics cards from below.
