Future GPUs could consume as much power as a small house, according to a speculative roadmap shared by X user Daniel Romero. The projections cover NVIDIA’s GPU plans from 2032 to 2035, with core area shrinking and power draw soaring.
Core area shrinks while power and memory skyrocket
The roadmap includes the Rubin and Feynman architectures, with core area expected to drop from 728-750 mm2 to 600-700 mm2 in later generations. Single GPU power consumption is forecast to rise from 800-900W to 1000-1200W.
Spec comparison
| Spec | Rubin | Feynman | Later Generations |
|---|---|---|---|
| Core Area | 728 mm2 | 750 mm2 | 600-700 mm2 |
| Single GPU Power | 800-900W | 800-900W | 1000-1200W |
| Chip Packaging | N/A | N/A | 8-chip |
| HBM Stack Count | N/A | N/A | 16-32 |
| Memory Capacity | N/A | N/A | 6144 GB |
By 2035, GPUs may use 8-chip packaging and up to 32 HBM stacks. Memory capacity could reach 6144 GB, with bandwidth hitting 1024 TB/s, or 1 PB/s.
Total card power might reach 15,360W, or 1.5 kilowatts. The article author notes that 2000-3000W titanium power supplies may become common to support such hardware.
These figures are speculative and based on a leaked roadmap, not official NVIDIA announcements. The timeline suggests extreme power and memory requirements for future computing.
