Radeon R9 380X vs Radeon RX 550: In-Depth Breakdown
Performance: Radeon R9 380X vs Radeon RX 550
The Radeon R9 380X 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 380X packs 2,048 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.
VRAM & Future-Proofing
The Radeon R9 380X carries 4GB versus 2GB on the Radeon RX 550. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Radeon R9 380X's memory is also faster — 182 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 380X (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 380X or Radeon RX 550?
The Radeon R9 380X 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.
