Radeon RX 7900 GRE vs GeForce RTX 3090: In-Depth Breakdown
Performance: Radeon RX 7900 GRE vs GeForce RTX 3090
The Radeon RX 7900 GRE is noticeably faster, around 10% ahead of the GeForce RTX 3090. That gap is enough to move it up a tier: the Radeon RX 7900 GRE is comfortable at 4K with upscaling and native 1440p, while the GeForce RTX 3090 is better matched to 1440p.
Price & Value
Right now the Radeon RX 7900 GRE starts at $231,051 JPY against $321,102 JPY for the GeForce RTX 3090. Because it's both faster and competitively priced, the Radeon RX 7900 GRE wins on performance-per-dollar by about 53%. The Radeon RX 7900 GRE still sits about $230,502 JPY above its $549 JPY MSRP. The GeForce RTX 3090 still sits about $319,603 JPY above its $1,499 JPY MSRP.
Power & Efficiency
The Radeon RX 7900 GRE draws just 260W versus 350W for the GeForce RTX 3090, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 24GB against 16GB, the GeForce RTX 3090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 7900 GRE's 16GB can fall short.
Generation & Longevity
The Radeon RX 7900 GRE is roughly 4 years newer than the GeForce RTX 3090 (RDNA 3 vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 3090 brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 7900 GRE offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce RTX 3090 or Radeon RX 7900 GRE?
The Radeon RX 7900 GRE 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.
