Key Takeaways
1. Major companies like Razer and HP are releasing gaming laptops with GeForce RTX 5090 graphics.
2. The mobile RTX 5090’s performance is closer to the desktop RTX 4070 Ti Super than to the desktop RTX 5090.
3. The mobile RTX 5090 has more unified shaders and cores than the desktop RTX 4070 Ti Super but performs lower due to a much lower TGP.
4. In real gaming scenarios, the mobile RTX 5090 can perform similarly to the desktop RTX 4070 Ti Super in high-demand games at 4K settings.
5. The mobile RTX 5090 offers better performance-per-watt compared to its raw performance, despite being more aligned with older desktop components.
Major companies such as Razer and HP have started to deliver their newest gaming laptops that come with GeForce RTX 5090 graphics. Although performance has improved compared to the mobile RTX 4090, the difference between it and the desktop RTX 5090 is quite large and arguably more pronounced than the difference between the mobile RTX 4090 and the desktop version. Our benchmark tests indicate that the mobile RTX 5090 is more similar to the desktop RTX 4070 Ti Super, as evidenced by the graphs below. The 3DMark results show only a small percentage difference between these two GPUs.
Performance Expectations
It’s a bit disappointing to see that the mobile RTX 5090 has more unified shaders, TMUs, ROPs, RT cores, and tensor cores than the desktop RTX 4070 Ti Super, yet it doesn’t perform as well. The main issue here is the much lower TGP of the mobile chip, which means that the GPU clock rates are roughly half of those found in the desktop versions. Hence, the theoretical performance is only in the low 30 TFLOPS range, compared to around 40 TFLOPS for the desktop RTX 4070 Ti.
Gaming Performance
However, there is a silver lining for the mobile RTX 5090 when it comes to playing real games, rather than just relying on synthetic benchmarks like 3DMark. Titles like Final Fantasy 15, Cyberpunk 2077, Black Myth: Wukong, and Alan Wake 2 at 4K with maximum settings show performance levels that are comparable to a desktop RTX 4070 Ti Super, despite the significant differences in TGP, according to our findings. This doesn’t even factor in any benefits from DLSS4 or MFG features, which would further widen the performance gap favoring the mobile RTX 5090. Therefore, laptop users can at least rely on the better performance-per-watt of the mobile RTX 5090, even if its raw performance is more in line with a last generation desktop component.
