Radeon RX Vega 64 vs Radeon RX 550: In-Depth Breakdown
Performance: Radeon RX Vega 64 vs Radeon RX 550
The Radeon RX Vega 64 is dramatically faster, around 1300% ahead of the Radeon RX 550. That gap is enough to move it up a tier: the Radeon RX Vega 64 is comfortable at 1080p, while the Radeon RX 550 is better matched to entry-level 1080p. The Radeon RX Vega 64 packs 4,096 stream processors versus 640 on the Radeon RX 550.
Price & Value
The Radeon RX 550 currently lists from $11,749 JPY, $128,693 JPY less than the Radeon RX Vega 64 at $140,442 JPY. Because it's both faster and competitively priced, the Radeon RX Vega 64 wins on performance-per-dollar by about 17%. The Radeon RX 550 still sits about $11,670 JPY above its $79 JPY MSRP. The Radeon RX Vega 64 still sits about $139,943 JPY above its $499 JPY MSRP.
Power & Efficiency
On power, the Radeon RX 550 is the gentler choice at 50W versus 295W. The Radeon RX Vega 64 is more efficient per watt because it's faster, but its higher 295W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX Vega 64 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 Vega 64's memory is also faster — 484 GB/s versus 96 GB/s (2048-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 Vega 64?
The Radeon RX Vega 64 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.
