So starting with the details, the rumor states that NVIDIA's GeForce RTX 5090 GPU will feature a very dense memory layout. In fact, it will be the densest design we have seen in several years as most modern-day high-end graphics cards have resorted to 384-bit memory interfaces at the max. Meanwhile, the NVIDIA GeForce RTX 5090 is expected to go one step ahead and relive the glory days of the 512-bit era.
The NVIDIA GeForce RTX 5090 GPU has been said to feature a 512-bit memory interface on several occasions and has been verified by other reliable leakers and it looks like we have the first layout pointed out within this rumor. There are going to be a total of 16 DRAM modules featured on the RTX 5090 PCB. All of these modules will be based on the GDDR7 standard and we know that initial dies will stick to 28 Gbps speeds. The GPU will have four memory modules on the top, five each on the sides, and two at the bottom. This new configuration will require a brand-new PCB design that will be capable of hosting the increased memory layout.
In that regard, NVIDIA is said to coming up with a brand new PCB solution. It is mentioned that the GeForce RTX 5090 Founders Edition card is going to make use of three separate PCB designs. It's not
