Radeon RX Vega 64 vs Radeon R9 380X: In-Depth Breakdown
Performance: Radeon RX Vega 64 vs Radeon R9 380X
The Radeon RX Vega 64 is dramatically faster, around 367% ahead of the Radeon R9 380X. That gap is enough to move it up a tier: the Radeon RX Vega 64 is comfortable at 1080p, while the Radeon R9 380X is better matched to entry-level 1080p. The Radeon RX Vega 64 packs 4,096 stream processors versus 2,048 on the Radeon R9 380X.
Price & Value
The Radeon RX Vega 64 currently lists from $195 USD, $154 USD less than the Radeon R9 380X at $349 USD. Because it's both faster and competitively priced, the Radeon RX Vega 64 wins on performance-per-dollar by about 735%. The Radeon RX Vega 64 is trading below its $499 USD MSRP — a genuine deal. The Radeon R9 380X still sits about $120 USD above its $229 USD MSRP.
Power & Efficiency
On power, the Radeon R9 380X is the gentler choice at 190W 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. Its more modern GCN 5.0 (Vega) architecture on a GloFo 14nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon RX Vega 64 carries 8GB versus 4GB on the Radeon R9 380X. The extra 4GB 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 182 GB/s (2048-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX Vega 64 is roughly 2 years newer than the Radeon R9 380X (GCN 5.0 (Vega) 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 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 R9 380X if you find it at a steep discount.
