Gaming Performance Comparison

Recommended System Requirements
Game Radeon RX Vega 56 8GB GeForce GTX 1080 Ti

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1080 Ti are noticeably better than the AMD Radeon RX Vega 56 8GB.

The RX Vega has a 20 MHz higher core clock speed and the same number of Texture Mapping Units as the GTX 1080 Ti. This results in the RX Vega providing 4.5 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RX Vega has a 20 MHz higher core clock speed than the GTX 1080 Ti, but the GTX 1080 Ti has 32 more Render Output Units than the RX Vega. As a result, the GTX 1080 Ti exhibits a 46.2 GPixel/s better Pixel Fill Rate than the RX Vega. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX Vega was released less than a year after the GTX 1080 Ti, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The GTX 1080 Ti has 3072 MB more video memory than the RX Vega, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the GTX 1080 Ti also has superior memory performance overall.

The GTX 1080 Ti has 228.4 GB/sec greater memory bandwidth than the RX Vega, which means that the memory performance of the GTX 1080 Ti is massively better than the RX Vega.

Both the Radeon RX Vega 56 8GB and the GeForce GTX 1080 Ti have 3584 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the GTX 1080 Ti is 7654 and by the RX Vega is 7654. Knowing that the shader performance of the GTX 1080 Ti is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The RX Vega transistor size technology is 2 nm (nanometers) smaller than the GTX 1080 Ti. This means that the RX Vega is expected to run very slightly cooler and achieve higher clock frequencies than the GTX 1080 Ti.

The Radeon RX Vega 56 8GB requires 300 Watts to run and the GeForce GTX 1080 Ti requires 220 Watts. We would recommend a PSU with at least 600 Watts for the RX Vega and a PSU with at least 600 Watts for the GTX 1080 Ti. The RX Vega requires 80 Watts more than the GTX 1080 Ti to run. The difference is significant enough that the RX Vega may have an adverse affect on your yearly electricity bills in comparison to the GTX 1080 Ti.

GPU Mini Review

Mini ReviewOverview
Radeon RX Vega 56 8GB is an Enthusiast gaming Graphics Card based on the Fourth (4.0) Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The Vega 10 XL GPU offers support for HBM-2 Memory, DirectX 12.0 and Open GL 4.5. While the Radeon RX Vega Eclipse uses the same Vega 10 XT GPU as the Radeon RX Vega 56 8GB, it is slightly down. This variant of the Vega 10 XL GPU with 56 Compute Units activated, offering 3584 Shader Processing Units, 224 TMUs and 56 ROPs, making it an estimated 12.5% slower than the Radeon RX Vega 64. This puts its predicted performance roughly in line with the GeForce GTX 1070.

GPU
The Central Unit is clocked at 1500MHz.

Memory: Speed
The GPU is equipped with stacked HBM-2 Memory and accesses the Frame Buffer through a 2048-bit memory interface.

Memory: Frame Buffer
The GPU can fill up a Memory Pool of up to 8GB. Under most circumstances, this only proves useful in certain 3D Games whose Settings Require Large Amounts of Memory.
However,the GPU itself is aimed for 4K Gaming, In some limited scenarios, 8GB might be a bottleneck and Performance could be better were the Frame Buffer larger, however this would only be an issue in the most demanding games.

Power Consumption
With a rated board TDP of 300W, it requires at least a 600W PSU with two available 8-pin connectors.

Performance
Radeon RX Vega 56 8GB competes with GeForce GTX 1070 8GB, which is available for $399.
Specs currently available suggest the Radeon RX Vega 56 8GB performance should be in the same region as the GeForce GTX 1070. However, the ultra-wide HBM2 memory may offer the Radeon RX Vega an advantage at higher resolutions.
System Suggestions
Radeon RX Vega 56 8GB HBM2 is best suited for resolutions up to and including 3840 x2160 (4K). We recommend a Very Strong Processor and at least 16GB of RAM for Optimal Performance.is
Overview
GeForce GTX 1080 Ti is the top 1000 Series graphics card and considered an Enthusiast graphics card based on the Pascal architecture.

Architecture
The Pascal architecture aims for twice as much Performance as the Maxwell Architecture and introduces support for second gen HBM.

GPU
It equips a GPU Codenamed P102-300-A1 which has 3584 Shader Processing Units, 224 TMUs and 88 ROPs. The central unit runs at 1480MHz and goes up to 1584MHz, in Boost mode.

Memory
The GPU accesses a 11.2GB frame buffer of second gen GDDR5X memory, through a 352-bit memory interface, while the Memory clock operates at 1376MHz.

Power Consumption
With a rated board TDP of 220W, it requires at least a 600W PSU with 2 power connectors, a 6-pin and an 8-pin connector.

System Suggestions
GeForce GTX 1080 Ti is best suited for resolutions up to and including 3840x2160. We recommend a High-End Processor and 16GB of RAM for optimal performance.
