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.
Price & Value
The GeForce RTX 3090 currently lists from $800 CAD, $1,205 CAD less than the GeForce RTX 2080 SUPER at $2,005 CAD. Because it's both faster and competitively priced, the GeForce RTX 3090 wins on performance-per-dollar by about 365%. The GeForce RTX 3090 is trading below its $1,499 CAD MSRP — a genuine deal. The GeForce RTX 2080 SUPER still sits about $1,306 CAD above its $699 CAD MSRP.
Power & Efficiency
On power, the GeForce RTX 2080 SUPER is the gentler choice at 250W versus 350W. The GeForce RTX 3090 is more efficient per watt because it's faster, but its higher 350W draw means more heat and a bigger PSU. 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 all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce RTX 2080 SUPER if you find it at a steep discount.
