GeForce RTX 3090 vs Arc A380: In-Depth Breakdown
Performance: GeForce RTX 3090 vs Arc A380
The GeForce RTX 3090 is dramatically faster, around 550% ahead of the Arc A380. That gap is enough to move it up a tier: the GeForce RTX 3090 is comfortable at 1440p, while the Arc A380 is better matched to entry-level 1080p.
Power & Efficiency
On power, the Arc A380 is the gentler choice at 75W versus 350W. The GeForce RTX 3090 is more efficient per watt because it's faster, but its higher 350W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The GeForce RTX 3090 carries 24GB versus 6GB on the Arc A380. The extra 18GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The Arc A380 is roughly 2 years newer than the GeForce RTX 3090 (Alchemist vs Ampere), 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 GeForce RTX 3090 offers NVIDIA DLSS upscaling/frame generation and stronger ray tracing. 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 GeForce RTX 3090?
The GeForce RTX 3090 is the faster card by about 550%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
