We shared news in October regarding Nvidia’s GeForce RTX 5090 laptop GPU, which is the top mobile graphics card in the RTX 50 Blackwell series, boasting 24 GB of VRAM. At that time, we mentioned that achieving 24 GB of VRAM on a 256-bit bus would necessitate using 3 GB GDDR7 modules. Thanks to the leaker Golden Pig Upgrade from China, we now have confirmation that the RTX 5090 laptop will indeed come with 24 GB of VRAM.
RTX 5090’s Unique Features
According to Golden Pig Upgrade, the RTX 5090 laptop will be the first in the RTX 50 series to utilize these 3 GB GDDR7 modules. This setup allows the GPU to have 24 GB of VRAM on a 256-bit bus. Interestingly, it seems that the RTX 5090 laptop will be the sole RTX 50 mobile card to adopt these 3 GB modules, while less powerful variants such as the RTX 5080 laptop will continue with standard memory configurations. For instance, the RTX 5080 laptop is expected to have a memory buffer of 16 GB.
Release Timeline
In other news, Golden Pig Upgrade suggests that gaming laptops featuring the RTX 5090 and RTX 5080 will launch in February. Meanwhile, models equipped with the mid-range RTX 5070 and RTX 5060 are expected to arrive a month later, around the end of March 2025. This aligns with CES, where manufacturers typically showcase their upcoming gaming laptops.
Performance Expectations
When the RTX 5090 laptop GPU is released, it may utilize the GB203 Blackwell GPU, the same chip found in the desktop RTX 5080. This GPU is thought to have 10,752 CUDA cores, a 256-bit bus, and a total TGP of 175 W. For comparison, the RTX 4090 laptop has 9,728 CUDA cores, a 256-bit bus, and a max TGP of 150 W. While the difference in CUDA cores is only about 10.5%, the architectural upgrades and increased power consumption should enable the RTX 5090 laptop to deliver a significant boost in performance.
Anticipated Performance
So, what kind of performance can we expect from the RTX 5090 laptop GPU? If we look at the RTX 4090 laptop’s performance, we might anticipate that the RTX 5090 laptop will perform similarly to the mid-range RTX 5070 desktop GPU, as the RTX 4090 mobile is like the RTX 4070 Super. Of course, this is a rough estimate of performance, so it’s likely that the RTX 5090 laptop could be even faster.
