GeForce RTX 3070 vs Arc A770: In-Depth Breakdown
Performance: GeForce RTX 3070 vs Arc A770
The GeForce RTX 3070 is significantly faster, around 35% ahead of the Arc A770. That gap is enough to move it up a tier: the GeForce RTX 3070 is comfortable at 1440p, while the Arc A770 is better matched to 1080p.
Price & Value
Right now the Arc A770 starts at $3,102 BRL against $3,868 BRL for the GeForce RTX 3070. Because it's both faster and competitively priced, the GeForce RTX 3070 wins on performance-per-dollar by about 8%. The Arc A770 still sits about $2,773 BRL above its $329 BRL MSRP. The GeForce RTX 3070 still sits about $3,369 BRL above its $499 BRL MSRP.
VRAM & Future-Proofing
With 16GB against 8GB, the Arc A770 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 3070's 8GB can fall short.
Generation & Longevity
The Arc A770 is roughly 2 years newer than the GeForce RTX 3070 (Alchemist vs Ampere), 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 RTX 3070 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 RTX 3070?
The GeForce RTX 3070 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 A770 if you find it at a steep discount.
