Arc A770 vs GeForce GTX 1080 Ti: In-Depth Breakdown
Performance: Arc A770 vs GeForce GTX 1080 Ti
The Arc A770 is noticeably faster, around 18% ahead of the GeForce GTX 1080 Ti. Both cards sit in the same broad class, well suited to 1080p.
Power & Efficiency
The Arc A770 sips power at 225W next to the GeForce GTX 1080 Ti's 250W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Arc A770's 16GB (vs 11GB on the GeForce GTX 1080 Ti) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Generation & Longevity
The Arc A770 is roughly 5 years newer than the GeForce GTX 1080 Ti (Alchemist vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A770 brings Intel XeSS upscaling and AV1 encoding, while the GeForce GTX 1080 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 A770 or GeForce GTX 1080 Ti?
The Arc A770 is the faster card by about 18%. 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.
