Among the dozens of rumors regarding the RTX 4000, known as the sAda Lovelace, a breakthrough in the use of lithography was expected. Specifically, in its size and process, which Moore's Law is Dead has been reporting that it is TSMC's 4nm, but in reality it would be the 4N process.
A recent fix to that leaker by WCCFtech now claims that these are 4N chips, not 4nm, because MLID made a typing error. If this is confirmed, it would give Ada Lovelace a certain advantage over AMD's RDNA 3, at least at the lithography level.
Now the RTX 4000 is speculated that they will have 4nm lithography
The Wccftech website highlights the fact that, by using the 4N node, Nvidia has chosen a process node specifically tailored to its needs. Among the advantages are improved energy efficiency , a performance boost, and a slight increase in density compared to TSMC's standard 5nm node. TSMC's 4N node is also used by Nvidia's Hopper GPUs for data centers.
Wccftech attributes the use of a technology typically reserved for other areas of computing, rather than for the consumer video card market, to speculation surrounding the power requirements of the RTX 40 series. Thus, the 4N process will allow Nvidia to further optimize these cards instead of relying on 5nm and 6nm process nodes.
In addition, a previous leak seemed to confirm that AMD's RX 7000 series could feature TSMC's 5nm and 6nm manufacturing processes. This decision would allow future AMD graphics cards to implement a multi-chip module design.
Although they differ from the 4N process in terms of optimization, if 5nm and 6nm process nodes are indeed AMD's choice, their RDNA 3 GPUs could outperform Nvidia's Ada GPUs in energy efficiency. The topic of electricity and power consumption has become increasingly critical in recent years due to concerns about electricity prices and availability, as well as its carbon footprint. Having graphics cards that consume less power can provide a significant advantage over competitors in any sector that monitors energy bills and is sensitive to price fluctuations.
