Today, a relatively reliable insider @kopite7kimi shared some very intriguing information. According to his sources, NVIDIA’s next high-end graphics card may get a 512-bit data bus between video memory and GPU. Last time gaming solutions of the Californian semiconductor giant were equipped with such an interface back in 2008 (GTX 280-285).
The so-called “Ada-Next”, or GeForce RTX 5090 according to the latest data will not be released before 2025 and with a high degree of probability will be powered by GDDR7 video memory. In addition, if the rumors about 512-bit interface are confirmed, the graphics adapter will get a 32 GB video buffer, which just corresponds to the above-mentioned data bus width.
This is a very pragmatic approach on NVIDIA’s part. After all, if they had chosen the 384-bit interface, increasing the amount of video memory from 24GB would have become a real headache for engineers. In fact, nobody actually needs to jump up to 48GB now, and staying at the same 24GB for more than 4 years makes no sense from the technological point of view.
In addition, the engineers of the green giant will have a huge scope for experimenting with the lowest video adapters. Judge for yourself: “cutting” the bus from 512 to 384 bits makes it possible to release a hypothetical RTX 5080 Ti, and cutting it down to 352 bits – RTX 5080.
Whether this information is confirmed or denied – we will only know at the end of this year/beginning of next year, when leaked benchmarks of test samples of the hypothetical GeForce RTX 5090 start leaking into the network.
