选择ASUS GeForce RTX，如果...
Grab the ASUS Prime if you're on a tight budget and just need a solid 1080p or light 1440p card that sips power at 105W.
选择Sapphire Radeon RX，如果...
Buy the Sapphire NITRO+ if you want maxed-out 4K gaming, heavy ray tracing, or AI workloads without spending RTX 4090 money.
主要区别
- VRAM is the headline: 24GB on the Sapphire vs 12GB on the ASUS. That's the difference between running 4K textures comfortably and hitting a wall in modern titles.
- Memory bandwidth tells the real story: 960 GB/s on the Sapphire vs 672 GB/s on the ASUS. The ASUS has newer GDDR7, but it's stuck on a narrow 128-bit bus, so the Sapphire still moves way more data.
- Power draw is night and day: 339W TDP on the Sapphire vs 105W on the ASUS. The Sapphire needs a beefy 850W+ PSU, while the ASUS will run on almost anything.
- Raw compute: 61.4 TFLOPS FP32 on the Sapphire vs 30.9 on the ASUS. The Sapphire is literally twice as fast in shader-heavy workloads.
- Customer sentiment is strong for both, but the Sapphire has way more reviews (688 vs 74). Owners consistently praise its quiet operation and cooling, though some mention occasional coil whine and the 4-slot size.
