Radeon R9 380 vs Radeon RX 550: In-Depth Breakdown
Performance: Radeon R9 380 vs Radeon RX 550
The Radeon R9 380 is dramatically faster, around 200% ahead of the Radeon RX 550. Both cards sit in the same broad class, well suited to entry-level 1080p. The Radeon R9 380 packs 1,792 stream processors versus 640 on the Radeon RX 550.
Power & Efficiency
At 50W against 190W, the Radeon RX 550 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern GCN 4.0 (Polaris) architecture on a GloFo 14nm process is part of why it does more with each watt.
Memory & Bandwidth
The Radeon R9 380's memory is faster — 176 GB/s versus 96 GB/s (256-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 550 is roughly 2 years newer than the Radeon R9 380 (GCN 4.0 (Polaris) vs GCN 3.0), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon R9 380 or Radeon RX 550?
The Radeon R9 380 is the faster card by about 200%. 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.
