Overview
Different tiers, different philosophies. I ran the RTX 5080 and the Sapphire NITRO+ RX 9070 XT through my full benchmark suite knowing the 5080 would be faster. It is. The real question: is the performance gap worth the significant jump in cost, power, and heat? For most people, I don’t think so.
Quick answer: The Sapphire NITRO+ RX 9070 XT wins on value. You get 75-80% of the RTX 5080’s gaming performance while running cooler, quieter, and drawing 100W less power.

Gaming Performance
The RTX 5080 is the faster card. No debate. At 1440p in Cyberpunk 2077, I measured 168 fps on the 5080 versus 118 fps on the NITRO+. That’s roughly a 42% lead. Across my full benchmark suite, the 5080 averaged 30-40% higher frame rates at 1440p.
At 4K, the gap stayed similar. The 5080 pushed 148 fps with DLSS Quality in Cyberpunk versus around 78 fps with FSR on the NITRO+ (using the reference 9070 XT numbers as a baseline, the NITRO+ adds 5-6% on top). Both cards have 16 GB of VRAM, so neither ran into memory limits at 4K.
Ray tracing is where the 5080 really separates itself. With RT Ultra, the NVIDIA card held frame rates that the NITRO+ couldn’t touch. If you play ray-traced titles regularly, this matters.
But here’s what the raw numbers don’t tell you. The NITRO+ was already pushing well above 100 fps at 1440p in every game I tested. That’s smooth, high-refresh gaming. The 5080 is faster, but you’re already past the point of diminishing returns for most monitors.
Power, Thermals, and Noise
This is the NITRO+‘s strongest argument. At 260W versus 360W, the Sapphire card draws 100W less under load. That’s a significant difference in heat output, electricity costs, and the PSU you need to buy.
The NITRO+ triple-fan cooler held 63C under sustained gaming. Nearly silent at 31 dBA. The RTX 5080 Founders Edition hit 72C and was clearly audible from my desk. You’ll also need a 750W PSU for the 5080 versus 700W for the NITRO+.
If noise and thermals matter to you, and they should, the NITRO+ is in a different league.
Features and Ecosystem
The RTX 5080 has the edge in software. DLSS 4 outperforms FSR 4 in image quality and game support. CUDA is the standard for AI, machine learning, and creative applications. NVENC is the best hardware encoder for streaming. If you do any AI or creative work alongside gaming, the 5080’s ecosystem wins.
The NITRO+ offers USB-C output for VR headsets, ARGB lighting, and Sapphire’s excellent build quality with a metal backplate. Both cards have 16 GB of VRAM, though the 5080’s GDDR7 has higher bandwidth than the NITRO+‘s GDDR6.
Verdict
I’m calling this for the Sapphire NITRO+ RX 9070 XT. Yes, the RTX 5080 is faster. Meaningfully so. But the NITRO+ delivers a gaming experience that’s already excellent at 1440p, runs 100W cooler, stays nearly silent, and costs significantly less. The 5080 is the right call if you game at 4K, need CUDA for work, or you prioritize ray tracing. For the typical 1440p gamer building a balanced system? The NITRO+ gives you everything you need without the power bill.
