Nvidia’s RTX 5090 could be getting a HUGE memory upgrade

Nvidia’s RTX 5090 will reportedly feature a 512-bit GDDR7 memory bus

A new RTX 5090 GPU leak has suggested that the graphics card will feature a multi-PCB design for its Founders Edition model. The GPU will also reportedly feature a denser memory configuration, with 16 total memory memory chips, and a new cooling solution.

With 16 total memory chips, it seems clear that Nvidia’s RTX 50 series flagship will feature a 512-bit memory bus. If these memory modules are 2 GB in size this will give Nvidia’s RTX 5090 32 GB of memory. Alternatively, the GPU could use 1GB memory chips and have 16GB of memory.

If Nvidia’s next-generation flagship has a 512-bit memory bus, it’s memory bus will be 33% wider than the memory bus on their RTX 4090. This upgrade will give Nvidia’s 5090 access to more memory bandwidth, even without faster GDDR7 memory modules.

Nvidia’s RTX 5090 will also reportedly feature a multi-PCB design and an unorthodox cooling solution. Nvidia’s next-generation Founders Edition flagship may feature a design where both side of the GPU are actively cooled. The GPU reportedly features three PCBs in total.

A 77% combined memory boost for Nvidia’s RTX 5090?

It has previously been reported that Nvidia’s RTX 50 flagship will feature 28 Gbps GDDR7 memory modules. These modules are 33% faster than the 21 Gbps memory modules on Nvidia’s RTX 4090. While many GDDR7 memory producers are already marketing 32Gbps GDDR7 modules, Nvidia may be opting for slower speeds initially to reduce costs and increase yields. It also opens the door to a “RTX 50 SUPER series” with faster GDDR7 modules if Nvidia ever wanted to explore that option.

With its wider memory bus and faster GDDR7 memory, Nvidia’s GeForce RTX 5090 graphics card should feature 77% more memory bandwidth than their RTX 4090. That’s a huge generational leap in memory performance. This would give Nvidia’s RTX 5090 almost 1,800 GB/s of memory bandwidth.
