In terms of overall gaming performance, the graphical capabilities of the AMD Radeon RX Vega 56 8GB are significantly better than the Nvidia GeForce GTX 780 Gainward Phantom GLH Edition.

The RX Vega has a 520 MHz higher core clock speed and 32 more Texture Mapping Units than the GTX 780. This results in the RX Vega providing 147.8 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 520 MHz higher core clock speed and 8 more Render Output Units than the GTX 780. This results in the RX Vega providing 37 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RX Vega was released over three years more recently than the GTX 780, and so the RX Vega is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 780 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 RX Vega has 5120 MB more video memory than the GTX 780, so is likely to be much better at displaying game textures at higher resolutions. However, overall, the GTX 780 has superior memory performance.

The GTX 780 has 32.4 GB/sec greater memory bandwidth than the RX Vega, which means that the memory performance of the GTX 780 is noticeably better than the RX Vega.

The Radeon RX Vega 56 8GB has 3584 Shader Processing Units and the GeForce GTX 780 Gainward Phantom GLH Edition has 2304. However, the actual shader performance of the RX Vega is 3494 and the actual shader performance of the GTX 780 is 2380. The RX Vega having 1114 better shader performance and an altogether better performance when taking into account other relevant data means that the RX Vega delivers a massively smoother and more efficient experience when processing graphical data than the GTX 780.

The RX Vega transistor size technology is 14 nm (nanometers) smaller than the GTX 780. This means that the RX Vega is expected to run slightly cooler and achieve higher clock frequencies than the GTX 780.

The Radeon RX Vega 56 8GB requires 300 Watts to run but there is no entry for the GeForce GTX 780 Gainward Phantom GLH Edition. 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 780. The two GPUs have been recommended a PSU with the same amount of wattage. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

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
GeForce GTX 780 Gainward Phantom GLH Edition is a special edition of the high-end GeForce GTX 780.
This edition comes with a custom triple fan cooling solution which by itself should allow a slight performance boost, as GeForce GTX 780 benefits from the GPU Boost 2.0 technology.
Also, it has been overclocked out of the box from 863MHz to 980MHz while its boost clock is now of 1033MHz. The memory clock was also increased to 1550MHz.
Benchmarks indicate a 8% performance boost when compared to the reference card.
