The latest NVIDIA RTX 50-series rumor is the top three SKUs will be the first to use GDDR7 memory modules. The next iteration of GDDR7 is already known to be arriving for enterprise and select consumer products within the next year or so. It has also been said that its early adoption in the consumer sector will see various configurations debut according to supply, and manufacturing cost limitations.
According to AGF (@XpeaGPU) via Tweaktown, “GDDR7 for top 3 Blackwell gaming dies confirmed”, which indicates that NVIDIA’s GB202 (aka RTX 5090), GB203 (RTX 5080), and GB204 (RTX 5070) could be the first NVIDIA consumer graphics cards to get the new VRAM. If true, the next questions will be in what capacities and frequency configurations. It also leads to the question of which type of memory bus each card gets. Ongoing speculation for the RTX 5090 suggests it will get an upgrade from 384-bit to 512-bit but that is yet to be confirmed.
RTX 5080 rumor:
The latest NVIDIA RTX 50-series rumors include another but to be fair, it’s more akin to water is wet than any sort of real speculation. AGF responded to a seemingly obvious question asking if the RTX 5080 would provide a noticeable performance increase over the RTX 4080. AGF replied that while it’s too early to tell, and that AMD’s offerings would play a factor in the RTX 5080’s final configuration, the GB203 GPU’s rasterization performance could be similar to that of the GB102 GPU while being faster at ray tracing.
Will depend on AMD competitiveness. So its too early to say but GB203 is close to AD102 in raster and faster in RT

While generational increases may vary in terms of overall percentages, NVIDIA has typically been, after hardware reviews are completed, shown to improve significantly with each new generational launch. Those percentages could be in the teens but sometimes go much higher. Newly added generational features can also play large factors in assessing performance uplift as seen with DLSS 2-3, Frame generation, and the ongoing addition of other RTX features.
So, as the rumor mill churns, these are some of the latest tidbits regarding the upcoming Blackwell GPU product line. As always treat them as rumors but there are at least some plausible possibilities of them becoming, at least in part, true.
