The RTX 5090 Is the Most Powerful Graphics Card Ever
The Nvidia 50-series GPUs were unveiled at CES 2025, focusing heavily on new AI features rather than traditional hardware-based raster performance. DLSS 4 technology is claimed to quadruple frame rates with minimal visual compromise. While the RTX 5090 does offer a performance boost over the previous RTX 40-series, the value for PC gamers remains a topic of debate.
In our review of the Nvidia GeForce RTX 5090 FE, Jackie Thomas noted that "the Nvidia GeForce RTX 5090 has officially taken the performance crown from the RTX 4090, albeit with a less significant leap than previous generations. In non-AI gaming, the RTX 5090's generational uplift is one of the smallest we've seen recently. However, in games that support it, DLSS 4 provides substantial performance gains, though it means that 75% of the frames are AI-generated."
