Sapphire Radeon RX 7900 XTX NITRO+ 24GB GDDR6 Silver
ASRock Radeon RX 6900 XT OC Formula 16GB GDDR6
Get the Sapphire NITRO+ if you want a card that crushes 4K gaming, handles ray tracing without breaking a sweat, and gives you 24GB of VRAM for future-proofing or AI workloads.
Pick the ASRock OC Formula RX6900XT if you're on a tighter budget and mostly game at 1080p or 1440p, where the performance gap shrinks and the savings actually matter.
主要区别
- The Sapphire has 24GB of VRAM on a 384-bit bus with 960 GB/s bandwidth, while the ASRock is stuck at 16GB on a 256-bit bus with 512 GB/s. That's a 50% bump in memory and nearly double the bandwidth, which matters a lot at 4K and for AI/LLM tasks.
- Raw compute is not even close. The Sapphire pushes 61.4 FP32 TFLOPS versus 23.0 on the ASRock, and its PassMark G3D score is 31,427 against 26,652. In real terms, the Sapphire is roughly 2.6x faster in FP32 workloads.
- The Sapphire wins on process node too, 5nm versus 7nm, which helps it run cooler and more efficiently despite the higher power draw. Owners consistently praise its quiet operation and low temps, while ASRock buyers mention the card runs hot under load.
- For ray tracing, the Sapphire scores 93 versus the ASRock's 80, and it has 96 RT cores against 80. If you care about RT performance in modern titles, the ASRock will struggle where the Sapphire doesn't.
- The ASRock's only spec win is budget, scoring 83 versus 76. But with 688 reviews averaging 4.4/5 for the Sapphire and 49 reviews at 4.3/5 for the ASRock, the Sapphire's real-world reputation is stronger and backed by way more data.
