Radeon RX 7900 GRE vs GeForce RTX 3080: In-Depth Breakdown
Performance: Radeon RX 7900 GRE vs GeForce RTX 3080
The Radeon RX 7900 GRE is significantly faster, around 23% ahead of the GeForce RTX 3080. 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 3080 is better matched to 1440p.
Price & Value
The GeForce RTX 3080 currently lists from $4,072 BRL, $3,748 BRL less than the Radeon RX 7900 GRE at $7,820 BRL. Despite being slower, the GeForce RTX 3080 offers the better performance-per-dollar (~56% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 3080 still sits about $3,373 BRL above its $699 BRL MSRP. The Radeon RX 7900 GRE still sits about $7,271 BRL above its $549 BRL MSRP.
Power & Efficiency
At 260W against 320W, the Radeon RX 7900 GRE is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the Radeon RX 7900 GRE at 16GB versus 10GB on the GeForce RTX 3080 — that extra 6GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Generation & Longevity
The Radeon RX 7900 GRE is roughly 4 years newer than the GeForce RTX 3080 (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 3080 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 3080 or Radeon RX 7900 GRE?
Choose the Radeon RX 7900 GRE if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 3080 stretches your money further for only slightly lower performance.
