Asking particular questions of senior CPU or GPU engineers is an fascinating train. Aside from being way more fascinating sources of knowledge than advertising and marketing people, engineers generally should assume years previously for a solution. That is as a result of that engineer might be already laborious at work on the next-next technology product. 

Right away, we’ve got comparatively little data on Nvidia’s next-gen Blackwell gaming GPUs. However even when we may ask senior engineers about it, they’re going to should assume again to Blackwell. At this cut-off date, Blackwell gaming GPU improvement is actually on the submit tape-out and software program improvement stage previous to its possible launch later this yr.

The technology following Blackwell is reportedly named Rubin. It is named after Vera Rubin, a pioneering astronomer. Her groundbreaking work consists of the properties of galaxies and proof of the existence of darkish matter. 

This data comes from Ming-Chi Kuo, a TF Securities analyst (through TechPowerUp). Kuo states that the R100 GPU will go into manufacturing within the fourth quarter of 2025, with full system options getting into manufacturing within the first half of 2026. Nvidia’s GPU nomenclature suggests R100 is a excessive finish AI centered GPU and never a gaming variant.

It is reportedly to be constructed with TSMC’s N3 node. It is going to incorporate HBM4 reminiscence and is being designed with energy effectivity in thoughts. Given that top finish AI GPUs are set to cross the kilowatt vary for only one card, any efforts to scale back energy consumption and enhance effectivity are welcome ones. Information facilities filled with these methods are more and more a problem to handle.

Kuo’s submit mentions a 4x reticle design and Chip-On-Wafer-On-Substrate-L (CoWoS-L) expertise. Relying on what number of chiplets a future R100 GPU incorporates, the tip end result may very well be a really massive chip. Nvidia may most likely cost $50,000 for one and it would not be shocking.

As for after we would possibly see Rubin gaming GPUs, your guess is pretty much as good as mine. If we comply with the Blackwell launch cadence, a late 2026 debut is an effective wager, with mainstream playing cards to comply with in 2027. That is an eternity in computing phrases.

A hypothetical GR102 chiplet-based RTX 6090 with 48GB of DDR7 could be welcome in my rig! Higher begin saving…
