Performance: GeForce RTX 5090 vs Radeon RX 7900 GRE
The GeForce RTX 5090 is dramatically faster, around 133% ahead of the Radeon RX 7900 GRE. That gap is enough to move it up a tier: the GeForce RTX 5090 is comfortable at 4K and high-refresh 1440p, while the Radeon RX 7900 GRE is better matched to 4K with upscaling and native 1440p.
Price & Value
Right now the Radeon RX 7900 GRE starts at $7,683 BRL against $30,021 BRL for the GeForce RTX 5090. Despite being slower, the Radeon RX 7900 GRE offers the better performance-per-dollar (~68% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 7900 GRE still sits about $7,134 BRL above its $549 BRL MSRP. The GeForce RTX 5090 still sits about $28,022 BRL above its $1,999 BRL MSRP.
Power & Efficiency
The Radeon RX 7900 GRE pulls less power (260W vs 575W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 5090 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
With 32GB against 16GB, the GeForce RTX 5090 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 7900 GRE's 16GB can fall short.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 5090 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 5090 or Radeon RX 7900 GRE?
Choose the GeForce RTX 5090 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 7900 GRE stretches your money further for only slightly lower performance.
