Radeon RX 580 vs Radeon RX 550: In-Depth Breakdown

Performance: Radeon RX 580 vs Radeon RX 550

The Radeon RX 580 is dramatically faster, around 500% ahead of the Radeon RX 550. Both cards sit in the same broad class, well suited to entry-level 1080p. The Radeon RX 580 packs 2,304 stream processors versus 640 on the Radeon RX 550.

Price & Value

Right now the Radeon RX 550 starts at $77 EUR against $149 EUR for the Radeon RX 580. Because it's both faster and competitively priced, the Radeon RX 580 wins on performance-per-dollar by about 211%. The Radeon RX 580 is trading below its $229 EUR MSRP — a genuine deal.

Power & Efficiency

The Radeon RX 550 pulls less power (50W vs 185W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 580 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.

VRAM & Future-Proofing

With 8GB against 2GB, the Radeon RX 580 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 550's 2GB can fall short. The Radeon RX 580'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 580?

The Radeon RX 580 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 550 if you find it at a steep discount.

Frequently Asked Questions

Is the Radeon RX 580 better than the Radeon RX 550?

The Radeon RX 580 is dramatically faster, roughly 500% ahead. If your budget allows, it's the stronger pick.

Which is better for 4K gaming, the Radeon RX 550 or the Radeon RX 580?

Neither is a dedicated 4K card; both are best at entry-level 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the Radeon RX 580 worth the extra $72 EUR over the Radeon RX 550?

Often yes — despite the higher price the Radeon RX 580 delivers better performance-per-dollar here.

Does the Radeon RX 580 have enough VRAM advantage to matter?

Its 8GB (vs 2GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
