AMD Radeon RX Vega 56 and 64: A Review of AMD’s Latest Graphics Cards

AMD has been hard at work developing new products to challenge its competitors, and the results are starting to show. The Ryzen and Threadripper CPUs have already caused Intel to lower its prices, and now, with the release of the AMD Radeon RX Vega 56 and RX Vega 64, AMD is making another splash in the market.

Not Completely New, but Close

The Vega series is not only the name of these cards but also the name of the GPU architecture inside them. While Vega is based on the Graphics Core Next (GCN) architecture, it still represents a significant revision. The compute units have been reworked, with AMD introducing Next-Generation Compute Units (NCUs) in Vega. The addition of Rapid Packed Math allows for double the processing throughput, which can be used to enhance various visual effects in games.

Memory has also been revamped in Vega. The High-Bandwidth Cache Controller (HBCC) improves memory access and reduces load times. AMD has rebranded the eight gigabytes of memory as High-Bandwidth Cache and has introduced High Bandwidth Memory 2, which provides fast and efficient memory performance.

The Numbers

The RX Vega 56 and RX Vega 64 have differing numbers of compute units, resulting in 3,584 and 4,096 Stream Processors, respectively. The memory bandwidth is also impressive, with the RX Vega 56 exceeding the Nvidia GTX 1080 in this aspect.

Familiar Design

The design of the RX Vega cards is similar to previous AMD reference cards, which may be a disappointment to some. However, the addition of a full backplate is a welcome improvement. There is also a limited-edition version of the air-cooled RX Vega 64 with an updated silver brushed aluminum shroud.

When it comes to performance, the RX Vega cards generally match or exceed the Nvidia GTX 1080. The RX Vega 56 is especially noteworthy, as it outperforms the GTX 1080 while being priced lower. However, the RX Vega cards fall short against the GTX 1080 Ti, which remains the top performer in its price range.

AMD’s Software Advantage

AMD’s Radeon Software Crimson Edition has made significant improvements over the years. It offers a range of useful tools and features that are easy to use. Additionally, AMD’s FreeSync technology provides a seamless gaming experience by matching the refresh rate of compatible monitors with the output of the RX Vega cards.

Our Verdict

The RX Vega 56 and RX Vega 64 provide a competitive option for high-end gaming. While they may not completely outshine Nvidia’s offerings, they offer solid performance at a lower price point. The RX Vega 56 is particularly impressive, delivering GTX 1080-level performance for $100 less. However, the RX Vega 64 is also a viable choice, especially if you have a budget of around $500.
