Sapphire Radeon RXがおすすめ：
Buy the Sapphire Nitro+ if you want excellent 4K gaming without selling a kidney, especially if you value quiet operation and a card that fits in more cases.
Gigabyte GeForce RTXがおすすめ：
Buy the Gigabyte Windforce RTX 5090 if you need the absolute fastest GPU on the market for 4K high-refresh gaming, AI workloads, or heavy compute tasks and don't care about the power bill.
主な違い
- The RTX 5090 has 32GB of GDDR7 on a 512-bit bus vs 24GB of GDDR6 on a 384-bit bus for the Sapphire, which matters for 4K texture-heavy games and AI/rendering work.
- PassMark G3D score is 38,958 for the Gigabyte vs 31,427 for the Sapphire, roughly a 24% raw performance gap, but the 5090 pulls 575W vs 339W and needs a 1000W PSU vs 800W.
- The Sapphire wins on clocks with a 2510 MHz base and 2680 MHz boost vs 2407/2467 on the Gigabyte, but the 5090's newer architecture and memory bandwidth more than make up for it.
- Real-world sentiment on the Sapphire is strong at 88/100 with buyers praising quiet operation, cool temps, and no coil whine, while the 5090's 575W TDP means heat and noise are bigger concerns.
- The Sapphire is dramatically cheaper per frame. The 7900 XTX typically sells for $800-900 while the RTX 5090 starts around $2,000, so you're paying roughly 2.5x the price for 24% more performance.
