Nvidia RTX 5090 Laptop GPU rumoured to pack 24GB of GDDR7 memory

Nvidia's upcoming GeForce RTX 5090 Laptop GPU might have more VRAM than we initially believed. Recent reports claim the flagship mobile GPU will feature 24GB of GDDR7 memory.

According to Golden Pig Upgrade, Nvidia reportedly uses the new 3GB GDDR7 modules to achieve this. With the RTX 5090 Laptop GPU expected to be based on the GB203 GPU, which is limited to a 256-bit memory bus, these 3GB modules allow for a non-standard 24GB configuration.

This aligns with the growing (but slow, especially for Nvidia) trend of increased memory capacity in desktop and laptop systems, with 24GB of DDR5 memory becoming increasingly common. The extra VRAM could provide a significant advantage in games and professional applications, especially at higher resolutions. The move to GDDR7 memory also promises a substantial increase in bandwidth for the RTX 50 series. While the exact speed of the GDDR7 memory in the RTX 5090 Laptop GPU remains unknown, desktop variants are rumoured to feature 28-32Gbps modules, a significant upgrade over the 21-23Gbps GDDR6X memory found in most RTX 40 series cards.

While the full specifications of the RTX 5090 Laptop GPU are still under wraps, it's expected to utilise the full GB203 GPU with 10,752 CUDA cores and a TGP of up to 175W. On the other hand, the RTX 5080 Laptop GPU is rumoured to feature a slightly cut-down GB203 GPU with 8,192 CUDA cores and 16GB of GDDR7 memory using standard 2GB modules.

According to the leak, the RTX 50 series Laptop GPUs will launch in February, starting with the flagship RTX 5090 and RTX 5080 models. The remaining SKUs, including the RTX 5070 and RTX 5060 series, are expected to follow later.
