NVIDIA RTX 5090 slimmer than 4090
Kopite7kimi corroborates on next-gen RTX 50 cooler rumors.
Last week, it was revealed that the NVIDIA RTX 5090 PCB will be more complex than the RTX 40 series. Instead of featuring a single board, the RTX 50 series will use three interconnected boards. This design is specific to the Founders Edition model from NVIDIA and may not be used in the reference models from other manufacturers.
NVIDIA likely had strong reasons for opting for such a complex cooler design for the RTX 5090. Prototypes for the GB202 Blackwell GPU, seemingly designed for the upcoming flagship RTX 5090, suggest it will occupy only two slots . This is a significant reduction compared to the bulky RTX 4090 Founders Edition or custom 4090 models, which typically take up 3 to 4 slots.
No, RTX 5090 FE has a 2-slot cooler.

NVIDIA likely had strong reasons for opting for such a complex cooler design for the RTX 5090. Prototypes for the GB202 Blackwell GPU, seemingly designed for the upcoming flagship RTX 5090, suggest it will occupy only two slots. This is a significant reduction compared to the bulky RTX 4090 Founders Edition or custom 4090 models, which typically take up 3 to 4 slots. Kopite also clarified that despite the slimmer design, the Founders Edition would still only have two fans .
Speculating about the RTX 5090’s specifications might be premature, but here’s what we know so far: The full GB202 GPU is expected to have up to 192 Streaming Multiprocessors. Similar to the RTX 4090, the 5090 will likely have fewer cores than the full chip, though the exact number is still unknown.
What’s more certain is that the RTX 5090 will likely use a 512-bit memory bus. The memory capacity, however, depends on whether NVIDIA opts for 2GB or 3GB modules, as per JEDEC specifications. This means the card could end up with either 32GB or 24GB of memory. Rumors suggest the PCB is designed to support 16 GDDR7 modules, making the 32GB option more probable.
NVIDIA is not expected to make any announcements during the pre-Computex keynote this weekend. However, more details are likely to emerge over the summer, as the RTX 50 series is expected to be available by the end of the year.
