GeForce RTX 3090 vs GeForce RTX 2080 SUPER: In-Depth Breakdown
Performance: GeForce RTX 3090 vs GeForce RTX 2080 SUPER
The GeForce RTX 3090 is dramatically faster, around 86% ahead of the GeForce RTX 2080 SUPER. That gap is enough to move it up a tier: the GeForce RTX 3090 is comfortable at 1440p, while the GeForce RTX 2080 SUPER is better matched to 1080p. The GeForce RTX 3090 packs 10,496 CUDA cores versus 3,072 on the GeForce RTX 2080 SUPER.
Power & Efficiency
At 250W vs 350W, the GeForce RTX 2080 SUPER is the gentler load on your system. The GeForce RTX 3090's extra power draw buys more performance per watt, not just more heat — worth it if your PSU has the headroom. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 3090 carries 24GB versus 8GB on the GeForce RTX 2080 SUPER. The extra 16GB 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 496 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 2080 SUPER or GeForce RTX 3090?
The GeForce RTX 3090 is the faster card by about 86%. 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.
