GeForce RTX 4080 SUPER vs GeForce RTX 3090: In-Depth Breakdown
Performance: GeForce RTX 4080 SUPER vs GeForce RTX 3090
The GeForce RTX 4080 SUPER is dramatically faster, around 44% ahead of the GeForce RTX 3090. That gap is enough to move it up a tier: the GeForce RTX 4080 SUPER is comfortable at 4K with upscaling and native 1440p, while the GeForce RTX 3090 is better matched to 1440p.
Price & Value
The GeForce RTX 4080 SUPER currently lists from $17,232 BRL, $571 BRL less than the GeForce RTX 3090 at $17,803 BRL. Because it's both faster and competitively priced, the GeForce RTX 4080 SUPER wins on performance-per-dollar by about 48%. The GeForce RTX 4080 SUPER still sits about $16,233 BRL above its $999 BRL MSRP. The GeForce RTX 3090 still sits about $16,304 BRL above its $1,499 BRL MSRP.
Power & Efficiency
At 320W against 350W, the GeForce RTX 4080 SUPER is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Ada Lovelace architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 3090 carries 24GB versus 16GB on the GeForce RTX 4080 SUPER. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 3090's memory is also faster — 936 GB/s versus 736 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 4080 SUPER is roughly 4 years newer than the GeForce RTX 3090 (Ada Lovelace vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 3090 or GeForce RTX 4080 SUPER?
The GeForce RTX 4080 SUPER 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 RTX 3090 if you find it at a steep discount.
