New details have emerged regarding the very powerful NVIDIA GeForce RTX 5090 from the “Blackwell” series, including a completely new PCB board design and 512-bit GDDR7 interface memory. These updates are promising significant improvements in memory management and overall GPU performance.
According to the latest rumors from the Chiphell forum, discussed by user Panzerlied, the GeForce RTX 5090 will feature an extremely dense memory configuration, the densest seen in recent years.
This design is different from modern high-end graphics card memory interfaces, which are generally stuck at 384 bit, marking a return to the 512-bit era.
A recent rendered image shows the memory configuration of the RTX 5090 based on these rumors. The board is said to have a total of 16 GDDR7 DRAM modules, positioned with four modules on top, five on each side, and two on the bottom.
This setup will require a completely new PCB designcapable of supporting a more complex layout and a greater amount of memory.
The GeForce RTX 5090 Founders Edition, in fact, it seems that it will use three separate PCBs. It is currently unclear whether this refers to three individual PCBs within a single board or something completely different.
The cooling solution contemplates a dual fan system to dissipate heat generated by the GPU and memory. There is also talk of double-sided memory, and at the moment up to 32 GB of memory can be anticipated, with workstation variants reaching up to 64 GB.
There is also talk of possible new cooling solutions for the GeForce RTX 50 “Blackwell” line of graphics cards, and it will certainly be interesting to see these prototypes in action and find out if these designs will be implemented in the final products available on the market. The NVIDIA GeForce RTX 5080 and RTX 5090 are currently expected to launch in the fourth quarter of 2024.
Below is a brief overview of the preliminary specifications of the NVIDIA GeForce RTX 50 “Blackwell” lineup:
- GeForce RTX 5090: GB202 GPU, 192 SMs/TBD cores, 512-bit (GDDR7) memory configuration, TDP 450W?
- GeForce RTX 5080: GB203 GPU, 96 SMs/TBD cores, 256-bit memory configuration (GDDR7), TDP 320W
- GeForce RTX 5070: GPU GB205, TBD, 192-bit memory configuration (GDDR7), TDP 225W
- GeForce RTX 5060 Ti: GPU GB206, TBD, 128-bit memory configuration (GDDR6?), TDP 160W
- GeForce RTX 5060: GPU GB207, TBD, 128-bit memory configuration (GDDR6?), TDP 120W
