Arc A580 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: Arc A580 vs GeForce GTX 1660 SUPER
The Arc A580 is dramatically faster, around 45% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the Arc A580 is comfortable at 1080p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p.
Price & Value
The GeForce GTX 1660 SUPER currently lists from $155 USD, $10 USD less than the Arc A580 at $165 USD. Because it's both faster and competitively priced, the Arc A580 wins on performance-per-dollar by about 37%. The GeForce GTX 1660 SUPER is trading below its $229 USD MSRP — a genuine deal.
Power & Efficiency
On power, the GeForce GTX 1660 SUPER is the gentler choice at 125W versus 175W. The Arc A580 is more efficient per watt because it's faster, but its higher 175W draw means more heat and a bigger PSU. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the Arc A580 at 8GB versus 6GB on the GeForce GTX 1660 SUPER — that extra 2GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Generation & Longevity
The Arc A580 is roughly 4 years newer than the GeForce GTX 1660 SUPER (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 SUPER 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 SUPER?
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 SUPER if you find it at a steep discount.
