Key Takeaways
1. The GeForce RTX 5090 Laptop GPU has achieved a score of 28,280 in PassMark’s G3D Mark, making it the highest-performing mobile GPU currently available, surpassing the RTX 4090 Laptop GPU by a small margin of +2.79%.
2. The RTX 5090 Laptop GPU features enhanced specifications, including 24 GB of GDDR7 memory and 10,496 CUDA cores, compared to the 16 GB GDDR6 and 9,728 cores of the RTX 4090 Laptop GPU.
3. The GPU has a thermal design power (TDP) ranging from 95-150 W, positioning it between the AMD Radeon RX 6950 XT and the Radeon PRO W7800 in performance rankings.
4. Reactions to the RTX 5090’s performance are mixed; Nvidia supporters celebrate its top spot, while critics note its minimal advantage over the RTX 4090 and the age of the desktop cards it outperforms.
5. Compatibility issues may affect the performance readings of the RTX 5090 Laptop GPU in benchmarks, as Nvidia has discontinued support for 32-bit frameworks, prompting PassMark to develop a patch for more accurate representation.
A GeForce RTX 5090 Laptop GPU has surfaced in PassMark’s G3D Mark performance chart for top-tier video cards, currently boasting a score of 28,280 that places it above the RTX 4090 Laptop GPU. This indicates that the Blackwell chip has taken the title of the highest-performing mobile GPU on the platform, although only one sample has been logged as of now. The RTX 5090 Laptop GPU, with a thermal design power (TDP) ranging from 95-150 W, is positioned slightly above the AMD Radeon RX 6950 XT desktop graphics card (which came out in 2022) and just below the Radeon PRO W7800 desktop graphics card (released in 2023) in the latest rankings.
Varied Reactions
Depending on your preference for GPU brands, this might be seen as either an impressive outcome or a disappointing one. Those in favor of Nvidia will likely be thrilled that the GeForce RTX 5090 Laptop GPU has secured the top spot among mobile GPUs on the benchmark, achieving this with significantly lower TDPs compared to desktop models. However, critics may highlight the age of the desktop cards it surpasses and the minimal margin separating the RTX 5090 Laptop from the RTX 4090 Laptop (just +2.79%). In this instance, transitioning from an Ada Lovelace GPU to a Blackwell one appears to have its advantages.
Enhanced Specifications
To begin with, the RTX 5090 Laptop GPU is equipped with 24 GB of GDDR7 memory (while the 4090 Laptop has 16 GB GDDR6) and features 10,496 CUDA cores in contrast to its predecessor’s 9,728 cores. The new RTX 50-series mobile GPUs are expected to offer improved processing efficiency, aided by the latest Max-Q technologies which introduce many optimizations. Yet, amidst all these advancements, one might wonder why the RTX 5090 Laptop GPU is only +2.79% ahead of the RTX 4090 Laptop GPU (as found in the Alienware M18 R2, available on Amazon) in the primary performance chart and even seems to be on par with RTX 4060 Laptop GPU levels in PassMark’s GPU Compute evaluation.
Potential Issues
This could likely stem from compatibility challenges. As previously mentioned, PassMark has revealed that the underwhelming performances of RTX 50-series cards in this specific benchmark may be attributed to Nvidia discontinuing support for 32-bit frameworks. The platform is currently working on a patch to ensure that Team Green’s products receive a more accurate representation in the benchmarks offered. As illustrated in the comparison below, the RTX 5090 Laptop GPU clearly outperforms the RTX 4060 Laptop GPU in DirectX 9-12 tests, yet it appears to perform comparably in GPU Compute. Regardless, this marks a promising beginning for Nvidia’s premier mobile chip, demonstrating its ability to achieve a high benchmark result even under less-than-ideal conditions.
