Arc A580 vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: Arc A580 vs GeForce GTX 1660 Ti
The Arc A580 is dramatically faster, around 45% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the Arc A580 is comfortable at 1080p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p.
Price & Value
Pricing has the Arc A580 at $2,030 BRL, $868 BRL under the GeForce GTX 1660 Ti's $2,898 BRL. Because it's both faster and competitively priced, the Arc A580 wins on performance-per-dollar by about 108%. The Arc A580 still sits about $1,851 BRL above its $179 BRL MSRP. The GeForce GTX 1660 Ti still sits about $2,619 BRL above its $279 BRL MSRP.
Power & Efficiency
Power draw favors the GeForce GTX 1660 Ti (120W vs 175W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter.
VRAM & Future-Proofing
The Arc A580 carries 8GB versus 6GB on the GeForce GTX 1660 Ti. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The Arc A580 is roughly 4 years newer than the GeForce GTX 1660 Ti (Alchemist vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce GTX 1660 Ti 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 A580 or GeForce GTX 1660 Ti?
The Arc A580 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce GTX 1660 Ti if you find it at a steep discount.
