Radeon R7 370 vs Radeon RX 550: In-Depth Breakdown
Performance: Radeon R7 370 vs Radeon RX 550
The Radeon R7 370 and Radeon RX 550 post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to entry-level 1080p gaming. The Radeon R7 370 packs 1,024 stream processors versus 640 on the Radeon RX 550.
Power & Efficiency
The Radeon RX 550 draws just 50W versus 110W for the Radeon R7 370, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. 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 R7 370's memory is faster — 179 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 R7 370 (GCN 4.0 (Polaris) vs GCN 1.0), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon R7 370 or Radeon RX 550?
The Radeon R7 370 is the faster card. 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.
