GeForce RTX 5090 rumors take shape
Chiphell leaker who revealed the first details on NVIDIA’s next-gen consumer GPU lineup now shares new rumors about the capabilities of the new architecture.
As a reminder, Panzerlied was the individual who initially revealed that NVIDIA plans to skip the XXX04-class GPU in their upcoming gaming product series. Upon this disclosure, we reached out to Kopite7kimi, a well-respected NVIDIA insider, who subsequently confirmed these rumors. Kopite7kimi also informed us that the upcoming NVIDIA RTX 50 series would adopt the GB2XX naming convention.
Today, Kopite7kimi has shared new details about the Blackwell series, which serves as the codename for NVIDIA’s next-generation GPU lineup. It is now anticipated that Blackwell will encompass both data-center and gaming series. However, there will be distinct naming schemes for these two GPU series, with GB1XX designated for high-performance computing (HPC) and GB2XX for gaming GPUs.
Meanwhile, Panzerlied has provided some insights into what graphics enthusiasts can expect from the next-generation NVIDIA lineup. Instead of providing specific numerical values, Panzerlied is sharing percentage improvements across various aspects of the Blackwell family.
NVIDIA RTX 5090 vs. RTX 4090
- 50% increase in scale (presumably cores)
- 52% increase in memory bandwidth
- 78% increase in cache (presumably L2 cache)
- 15% increase in frequency (presumably GPU boost)
- 1.7x improvement (presumably performance)
Panzerlied later clarified in the thread that those claims are in reference to RTX 4090 specs, not AD102. If we consider that the RTX 4090 with 21 Gbps memory would see an upgrade to 32 Gbps (a 52.4% increase), this would suggest that the RTX 50 series might feature GDDR7 technology. It’s worth mentioning that the successor to the AD102 is also rumored to include a 512-bit memory bus, although it may not necessarily be used in the RTX 5090 specifically; it could be reserved for a TITAN/RTX workstation or a future 5090Ti variant.
It seems unlikely NVIDIA might adopt the fastest GDDR7 memory on their card since day one, so RTX 5090 configurations such as 512-bit/24 Gbps or 448-bit/28 Gbps could also be considered.
Assuming that other claims are also based on the RTX 4090 as a reference point, a 15% increase in frequency would translate to a 2.9 GHz boost clock, with actual workloads likely achieving clocks of 3.0 GHz or higher. Additionally, a 78% increase in cache suggests that the GB202 GPU would feature 128MB of L2 cache.
We are more than a year away from the potential launch of the next-gen GeForce series, however just for fun, if we were to extrapolate these specifications to a potential RTX 5090 GPU, it might look something like this:
