The NVIDIA GeForce RTX 5090 is expected to have a much wider memory interface than the GeForce RTX 4090. This is according to hardware tipster kopite7kimi, who has been told by their sources that NVIDIA’s next flagship gaming GPU will have a 512-bit memory interface—128 bits higher than what the GeForce RTX 4090 is currently working with. Some have pointed out that this sort of specification hasn’t been seen since ancient GeForce releases, such as the GeForce GTX 280, which launched way back in June 2008. kopite7kimi also claimed today that the GeForce RTX 4090 Ti has been canceled, although more GeForce RTX 4070 and 4060 models are said to be coming.
This would be a major shift in NVIDIA gaming lineup, considering such configuration has not been used for a long time, like GTX 280 or some dual-GPU models. If NVIDIA were to use GDDR7 memory with the max speed of 32 Gbps on such a potential next-gen GPU, this would result in 2TB/s bandwidth, so double what RTX 4090 offers.
However, NVIDIA is unlikely to use the fastest G7 memory at launch, and just the fact that the GPU may support a 512-bit bus does not guarantee that such configuration will be enabled for each variant.
Combined with multiple sources, I confirm the gaming flagship of Ada-next will have a 512-bit memory interface.— kopite7kimi (@kopite7kimi) July 27, 2023
I'm afraid there won't be RTX 4090 Ti anymore. Some low-grade AD103 and AD106 chips will be another versions of RTX 4070 and 4060.— kopite7kimi (@kopite7kimi) July 27, 2023
