Key Takeaways
1. The RTX 5090 laptop GPU shows a 20% performance advantage over the RTX 4090 in synthetic tests but doesn’t translate to significant gaming performance gains.
2. In a broader gaming context, both the RTX 5090 and RTX 4090 perform similarly, with only slight advantages in some cases.
3. At lower resolutions like 1080p, CPU performance impacts GPU performance analysis, complicating comparisons between models.
4. The performance gap at 1440p and 4K is minimal, with the RTX 5090 only showing a 0.6% and 3% increase over the RTX 4090, respectively.
5. Key advantages of the RTX 5090 include 24 GB VRAM, improved efficiency, and DLSS Multi-Frame Generation, but the RTX 4090 may be a better investment for most users.
We did an analysis of the RTX 5090 and RTX 5080 laptop GPUs, and it shows these boards offer a solid performance advantage over their previous generation models in synthetic tests. For example, the RTX 5090 laptop outperformed the RTX 4090 laptop by as much as 20% in the 3DMark test suite. Nevertheless, this synthetic performance does not effectively translate into gaming performance, especially for the RTX 5090.
Performance in Gaming
Although the RTX 5090 laptop was 20% quicker than the RTX 4090 laptop for some individual games like Cyberpunk 2077 2.2 Phantom Liberty during our tests, it appears that the new GPU does not hold any edge over the RTX 4090 when evaluated in a broader context. The 25-game benchmark from Jarrod’sTech indicates that the RTX 5090 laptop and the RTX 4090 laptop perform largely on par.
Importance of Resolution
Before diving into the actual performance details, it’s worth noting that we have not considered the 1080p results. At lower resolutions, such as 1080p, CPU performance plays a bigger role, which complicates the process of determining the precise GPU performance.
When tested at 1440p, the RTX 5090 laptop GPU only manages to be a slight 0.6% faster than the RTX 4090 laptop GPU. This includes the notably poor performance of the RTX 5090 laptop in Red Dead Redemption 2. Even if we ignore the Red Dead Redemption 2 score, the RTX 5090 laptop shows a meager 1.6% lead over the RTX 4090 laptop GPU.
4K Performance Insights
The gap in gaming performance between the RTX 5090 laptop and the RTX 4090 laptop isn’t significantly better at 4K. Both GPUs perform quite similarly, with JT’s testing revealing only a 3% increase in performance for the RTX 5090 laptop GPU. This is with the Red Dead Redemption 2 results included. However, removing Red Dead Redemption 2 from the equation doesn’t improve things for the RTX 5090 laptop.
When looking at frame rates, the RTX 5090 laptop GPU averages 66 FPS across the 25 games tested at 4K, while the RTX 4090 laptop is nearly the same at 64.5 FPS. The results at 1440p also reflect this trend, with the RTX 5090 laptop GPU and the RTX 4090 laptop GPU averaging 107 and 106 FPS, respectively.
Final Thoughts
Ultimately, the RTX 5090 laptop GPU’s advantages are limited to its 24 GB VRAM, improved efficiency, and DLSS Multi-Frame Generation (MFG). However, it’s doubtful that anyone spending over $3,000 or $4,000 on a premium gaming laptop will prioritize efficiency. Buyers of high-end gaming laptops expect top-tier performance.
Thus, if you don’t plan to use MFG and have no need for 24 GB of VRAM, the previous generation RTX 4090 gaming laptops are evidently a better investment.
