Game Radeon RX Vega 56 8GB GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition

In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition are very slightly better than the AMD Radeon RX Vega 56 8GB.

The GTX 1080 has a 284 MHz higher core clock speed than the RX Vega, but the RX Vega has 64 more Texture Mapping Units than the GTX 1080. As a result, the RX Vega exhibits a 50.6 GTexel/s better Texture Fill Rate than the GTX 1080. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 1080 has a 284 MHz higher core clock speed and 8 more Render Output Units than the RX Vega. This results in the GTX 1080 providing 30.2 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 a year more recently than the GTX 1080, and so the RX Vega is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GTX 1080.

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 Radeon RX Vega 56 8GB and the GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GTX 1080 has 64.3 GB/sec greater memory bandwidth than the RX Vega, which means that the memory performance of the GTX 1080 is much better than the RX Vega.

The Radeon RX Vega 56 8GB has 3584 Shader Processing Units and the GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition has 2560. However, the actual shader performance of the RX Vega is 3494 and the actual shader performance of the GTX 1080 is 6691. The GTX 1080 having 3197 better shader performance and an altogether better performance when taking into account other relevant data means that the GTX 1080 delivers a significantly smoother and more efficient experience when processing graphical data than the RX Vega.

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

The Radeon RX Vega 56 8GB requires 300 Watts to run and the GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition requires 300 Watts. We would recommend a PSU with at least 600 Watts for the RX Vega and a PSU with at least 500 Watts for the GTX 1080. The two GPUs require the same amount of wattage to run. 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
Overview
GeForce GTX 1080 Asus ROG Strix Gaming OC 8GB Edition is a Special Edition of NVIDIA's High-End GeForce GTX 1080, created by Asus.

Overclock: Central Unit
The Central Unit has been increased from 1607MHz to 1784MHz, whereas the Boost Clock can now achieve 1936MHz, instead of 1733MHz.

Overclock: Memory Clock
None.

Frame Buffer
Untouched.


Cooling Solution
DirectCU III Technology with Direct-GPU Contact Heatpipes: Exclusive DirectCU III cooling technology features direct-GPU contact heatpipes that transports more heat away from the GPU and outperform reference designs, achieving up to 30% cooler gaming performance.

Performance
At 1920x1080, Benchmarks Indicate a 6% Performance Boost over the Reference GeForce GTX 1080. This goes up to 8% at 3840x2160.
