GeForce RTX 3090 vs GeForce RTX 2070: In-Depth Breakdown
Performance: GeForce RTX 3090 vs GeForce RTX 2070
The GeForce RTX 3090 is dramatically faster, around 160% ahead of the GeForce RTX 2070. That gap is enough to move it up a tier: the GeForce RTX 3090 is comfortable at 1440p, while the GeForce RTX 2070 is better matched to 1080p. The GeForce RTX 3090 packs 10,496 CUDA cores versus 2,304 on the GeForce RTX 2070.
Price & Value
Right now the GeForce RTX 2070 starts at $549 GBP against $1,282 GBP for the GeForce RTX 3090. Because it's both faster and competitively priced, the GeForce RTX 3090 wins on performance-per-dollar by about 11%. The GeForce RTX 3090 is trading below its $1,499 GBP MSRP — a genuine deal.
Power & Efficiency
The GeForce RTX 2070 pulls less power (175W vs 350W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 3090 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
With 24GB against 8GB, the GeForce RTX 3090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 2070's 8GB can fall short. The GeForce RTX 3090's memory is also faster — 936 GB/s versus 448 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 3090 is roughly 2 years newer than the GeForce RTX 2070 (Ampere vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 2070 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 2070 if you find it at a steep discount.
