Radeon RX 5700 vs Radeon RX Vega 56: In-Depth Breakdown
Performance: Radeon RX 5700 vs Radeon RX Vega 56
The Radeon RX 5700 is significantly faster, around 25% ahead of the Radeon RX Vega 56. That gap is enough to move it up a tier: the Radeon RX 5700 is comfortable at 1080p, while the Radeon RX Vega 56 is better matched to entry-level 1080p.
Power & Efficiency
The Radeon RX 5700 sips power at 180W next to the Radeon RX Vega 56's 210W, and still leads on performance-per-watt — quieter, cooler, and gentler on your 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'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 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 or Radeon RX Vega 56?
The Radeon RX 5700 is the faster card by about 25%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
