New information from reliable leakers suggests that the NVIDIA GeForce RTX 5090 will have a 575W TDP (Thermal Design Power), while the RTX 5080 will have a 360W TDP. These figures confirm higher power demands than their predecessors.
RTX 5090: Higher Power and Performance
The RTX 5090's 575W TDP is a significant increase compared to the 450W TDP of the RTX 4090. This is not entirely unexpected due to its high-end specifications which include a GB202 GPU with 21,760 CUDA cores and 32GB of GDDR7 memory with a 512-bit interface.
RTX 5090 Key Specifications (Rumored):
- GPU: GB202
- CUDA Cores: 21,760
- Memory: 32GB GDDR7
- Memory Interface: 512-bit
- TDP: 575W
RTX 5080: Lower Power, Still Impressive
The RTX 5080's TDP has been finalized at 360W, which is lower than previously rumored 400W but still higher than the RTX 4080 and 4080 SUPER. It will feature a GB203 GPU with 10752 CUDA cores and 16GB of GDDR7 memory.
RTX 5080 Key Specifications (Rumored):
- GPU: GB203
- CUDA Cores: 10,752
- Memory: 16GB GDDR7
- TDP: 360W
And RTX 5080 360W.

Other Features and Availability
Both the RTX 5090 and RTX 5080 are expected to support PCIe 5.0 and DisplayPort 2.1a. However, leaked packaging suggests there might not be significant technological upgrades beyond these. NVIDIA is expected to announce pricing next week, but the RTX 5090 still lacks a firm release date.
