Radeon RX 590 vs Radeon RX 550: In-Depth Breakdown
Performance: Radeon RX 590 vs Radeon RX 550
The Radeon RX 590 is dramatically faster, around 600% ahead of the Radeon RX 550. Both cards sit in the same broad class, well suited to entry-level 1080p. The Radeon RX 590 packs 2,304 stream processors versus 640 on the Radeon RX 550.
Price & Value
The Radeon RX 550 currently lists from $18 CAD, $772 CAD less than the Radeon RX 590 at $790 CAD. Despite being slower, the Radeon RX 550 offers the better performance-per-dollar (~523% better value), so budget-focused buyers should weigh it carefully.

Power & Efficiency
On power, the Radeon RX 550 is the gentler choice at 50W versus 225W. The Radeon RX 590 is more efficient per watt because it's faster, but its higher 225W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 590 carries 8GB versus 2GB on the Radeon RX 550. The extra 6GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Radeon RX 590's memory is also faster — 256 GB/s versus 96 GB/s (256-bit vs 128-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Radeon RX 550 or Radeon RX 590?
Choose the Radeon RX 590 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 550 stretches your money further for only slightly lower performance.
