Radeon RX 5700 XT vs Radeon RX Vega 56: In-Depth Breakdown
Performance: Radeon RX 5700 XT vs Radeon RX Vega 56
The Radeon RX 5700 XT is dramatically faster, around 50% ahead of the Radeon RX Vega 56. That gap is enough to move it up a tier: the Radeon RX 5700 XT is comfortable at 1080p, while the Radeon RX Vega 56 is better matched to entry-level 1080p.
Price & Value
The Radeon RX Vega 56 currently lists from $27 EUR, $1,067 EUR less than the Radeon RX 5700 XT at $1,095 EUR. Despite being slower, the Radeon RX Vega 56 offers the better performance-per-dollar (~2582% better value), so budget-focused buyers should weigh it carefully. The Radeon RX Vega 56 is trading below its $399 EUR MSRP — a genuine deal. The Radeon RX 5700 XT still sits about $696 EUR above its $399 EUR MSRP.
Power & Efficiency
On power, the Radeon RX Vega 56 is the gentler choice at 210W versus 225W. The Radeon RX 5700 XT is more efficient per watt because it's faster, but its higher 225W draw means more heat and a bigger PSU. Its more modern RDNA architecture on a TSMC N7 process is part of why it does more with each watt.
Memory & Bandwidth
The Radeon RX 5700 XT's memory is faster — 448 GB/s versus 410 GB/s (256-bit vs 2048-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 5700 XT is roughly 2 years newer than the Radeon RX Vega 56 (RDNA vs GCN 5.0 (Vega)), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 5700 XT or Radeon RX Vega 56?
Choose the Radeon RX 5700 XT if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX Vega 56 stretches your money further for only slightly lower performance.
