Rumor mill: The launch of Nvidia’s RTX 50-series GPUs remains to be a great distance off, with rumors suggesting that it might occur both in late 2024 or early 2025. However, that is not stopping the rumor mill from churning out stories about their specs, structure, efficiency, and energy necessities.
According to the most recent put up by prolific tipster @kopite7kimi, the RTX 50 “Blackwell” graphics playing cards will likely be primarily based on the GB202 and GB203 GPUs. The former is predicted to be the complete fats flagship, whereas the latter would be the cut-down model with half the variety of cores. In comparability, the current-gen AD102 GPU underpinning the RTX 4090 lineup comes with 80 % extra cores than the AD103 that powers the RTX 4080 and decrease. However, the tipster was not sure about whether or not the GB202 will use a multi-chip bundle.
I feel GB203 is half of GB202, similar to GB102 and GB100. But I do not know if GB202 has a multi chip bundle.

Another rumor surrounding the upcoming graphics playing cards is that they could characteristic a 512-bit memory interface in contrast to the 384-bit interface discovered on the flagship AD102 Ada GPU. That’s in direct distinction to a rumor from final week, which claimed that the GB200 gaming GPUs will retain the very same memory interface as Ada, suggesting they’ll solely pack a 384-bit bus on the most.
Finally, the primary set of Blackwell gaming playing cards are additionally tipped to ship with 28Gbps GDDR7 memory, which is a tad decrease than the 32Gbps most capability of the GDDR7 chips. However, it will nonetheless be considerably sooner than earlier technology graphics memory, as GDDR6 solely supplied up to 18Gbps bandwidth, whereas GDDR6X went up to 21Gbps. While Nvidia is predicted to stick with 16Gbit densities for the GDDR7 memory chips, there is no phrase on the memory bus widths of the person SKUs.
28Gbps.

If the most recent report seems to be correct, it might imply a major efficiency increase for the RTX 5090, thanks to the additional cores from the GB202 GPU, the elevated memory bandwidth, and the 512-bit bus.
As with all rumors, these want to be taken with a pinch of salt. So much can nonetheless change between now and the eventual launch of the RTX 50-series playing cards.
