Rumor after rumor about the future RTX 5090. The aim here is to find out what the card’s configuration will be between now and its launch. While early rumors suggested a card with a 512-bit memory interface, today’s rumor suggests a different memory configuration.
RTX 5090: 28 GB GDDR7 in 448-bit…
Of course, all this must be taken with a grain of salt, as nothing is set in stone. This time, the rumor comes from the Chiphell forum via member Panzerlied.
According to him, NVIDIA’s 5090 will only offer a memory configuration with a 448-bit bus. This implies the use of fourteen memory chips. As we said, GDDR7 will initially only be available in 2 GB chips for the consumer sector. We should therefore be entitled to a graphics card with a total of 28 GB of VRAM. With these characteristics, we can estimate the card’s bandwidth at 1.5 TB/s with memory operating at 28 Gbps.
As our colleague points out, this also gives NVIDIA a bit of leeway if the need arises to offer slightly more complete cards. What’s more, the brand’s pro range is likely to feature GPUs with 512-bit memory interfaces, such as the Quadro series.
In the meantime, according to the latest rumors, the board could benefit from a PCB split into several modules. The heatsink would be much more compact than current models, with a dual-slot, dual-fan system. Finally, we can expect the first RTX 50s by the end of the year.
