The arrival of Nvidia’s GeForce RTX 50 series is stirring curiosity among gaming and tech enthusiasts, as new details suggest the GB203 and GB205 GPUs, which are expected to power the RTX 5080 and RTX 5070, respectively, will maintain the same bus widths as their Ada Lovelace predecessors.
Insider information hints that the GeForce RTX 5080 may feature the GB203 GPU with a 256-bit wide bus, paralleling the current RTX 4080’s AD103 GPU. Should this be the case, predictions surface that the RTX 5080 may be equipped with 16 GB of VRAM. The GB202 GPU, previously rumored for the top-tier RTX 5090, is speculated to come with a substantial 512-bit bus and the potential to support GDDR7 memory. Speculations on video memory for the RTX 5090 range from a substantial 32 GB to an impressive 36 GB.
As for the RTX 5070 or potentially even the RTX 5060, the GB205 GPU is rumored to have a 192-bit interface and may come with 12 GB of VRAM. As with any cutting-edge technology, details on the GB204 GPU are not yet disclosed, leaving room for anticipation.
These leaks, which first gained momentum around June 2022 when Ada Lovelace GPUs were taped out, have continued to surface, building expectations for the official announcement of the RTX 50 series Blackwell GPUs.
The new lineup, while still enshrouded in secrecy, promises to push forward Nvidia’s legacy in the graphics card domain. As the prologue of these graphics cards unfolds, the world eagerly awaits what is likely to be another leap in video gaming and high-performance computing.
