Radeon RX 7900 GRE vs Arc A380: In-Depth Breakdown
Performance: Radeon RX 7900 GRE vs Arc A380
The Radeon RX 7900 GRE is dramatically faster, around 617% ahead of the Arc A380. That gap is enough to move it up a tier: the Radeon RX 7900 GRE is comfortable at 4K with upscaling and native 1440p, while the Arc A380 is better matched to entry-level 1080p.
Price & Value
Right now the Arc A380 starts at $1,329 BRL against $7,683 BRL for the Radeon RX 7900 GRE. Because it's both faster and competitively priced, the Radeon RX 7900 GRE wins on performance-per-dollar by about 24%. The Arc A380 still sits about $1,190 BRL above its $139 BRL MSRP. The Radeon RX 7900 GRE still sits about $7,134 BRL above its $549 BRL MSRP.
Power & Efficiency
The Arc A380 pulls less power (75W vs 260W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7900 GRE draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 16GB against 6GB, the Radeon RX 7900 GRE has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc A380's 6GB can fall short.
Generation & Longevity
The Radeon RX 7900 GRE is roughly 2 years newer than the Arc A380 (RDNA 3 vs Alchemist), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A380 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 7900 GRE offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Arc A380 or Radeon RX 7900 GRE?
The Radeon RX 7900 GRE is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Arc A380 if you find it at a steep discount.
