Rumor: Nvidia RTX 5070 Ti Features 256-bit Memory Bus and 350W TBP
Wccftech has shared new speculative specifications for the Nvidia RTX 5070 Ti. According to their sources, the upcoming GPU is expected to feature 8,960 CUDA cores, 16GB of GDDR7 memory, and a 256-bit memory bus, delivering an impressive memory bandwidth of 896GB/s. The total board power (TBP) of the card could reportedly reach up to 350W.
Key Specifications Leaked
Insiders confirm that the RTX 5070 Ti will utilize the GB203-300 GPU, which is said to be the same processor found in the Nvidia RTX 5080. However, the RTX 5070 Ti version would be a scaled-down variant with reduced performance. While early leaks had suggested a TBP of 285W for this GPU, the latest information points to a higher maximum TBP of 350W. Trusted leaker Kopite7kimi corroborates this, but also mentions a potential 285W TBP variant.
Wccftech also notes that the RTX 5070 Ti will come equipped with 16GB of GDDR7 memory, running at a blistering 28Gbit/s. This configuration results in a memory bandwidth of 896GB/s, a significant leap over its predecessor, the RTX 4070 Ti. For comparison, the RTX 4070 Ti launched in early 2023 with 12GB of GDDR6X memory running at 21Gbit/s, connected via a 192-bit memory bus, delivering a total bandwidth of 504GB/s.

Speculation on RTX 50 Series Launch
Rumors surrounding Nvidia’s RTX 50 series have been circulating for some time. The company is expected to unveil several GPUs in the new series at the upcoming Consumer Electronics Show (CES) in Las Vegas. Nvidia CEO Jensen Huang is scheduled to deliver a keynote on Tuesday, January 7, 2025. Based on reports, the RTX 50 series is slated for release in early 2025.
The shift from Ada Lovelace (RTX 40 series) to the Blackwell architecture (RTX 50 series) is anticipated to bring significant performance improvements. While the RTX 4070 Ti was a strong contender in the mid-to-high-end GPU market, the rumored specs of the RTX 5070 Ti suggest a considerable leap in computational power and memory performance.
Conclusion
If the leaked specifications are accurate, the Nvidia RTX 5070 Ti is shaping up to be a highly capable graphics card with features that cater to demanding gaming and creative workloads. With its 256-bit memory bus, 16GB of GDDR7 memory, and a potential TBP of up to 350W, it appears poised to offer a substantial upgrade over its predecessor.
Gamers and tech enthusiasts will undoubtedly keep a close eye on CES 2025, where Nvidia is expected to reveal more details about the RTX 50 series. Until then, these rumors offer a tantalizing glimpse into the next generation of GPU performance.
