Rumors about next-gen GPUs are doing the rounds. The latest is that Nvidia’s upcoming RTX 40 series of graphics cards will be built using TSMC’s 4nm process node, giving the series a slight advantage over the 5nm process AMD expects to use for its next-generation RDNA3 GPUs generation will use.
Moore’s Law is dead (about wccftech) believes Ada Lovelace will be built using TSMC’s 4nm node. It can be confusing to talk about knots. It was assumed that Nvidia would use a node called 4N, which is a custom 5nm class process, but MLID explicitly states “4nm”. He knows what he’s talking about.
Nvidia’s “Hopper” workstation architecture is a 4nm product, but this is a very high-margin product, and Nvidia can easily recoup costs from sales to secure breakthrough wafer launches. We know that Nvidia pays big bucks to access production TSMC, but is the asking price for 4nm too high for a lower margin GeForce card?
Confused? We also. Whether Ada Lovelace ends up being a 5nm or 4nm or 4N or whatever, the vast majority of consumers won’t pay attention. As long as the card they choose performs as expected, it doesn’t matter which node they use.

Whether this really puts Nvidia a nanometer ahead of AMD’s competing products remains to be seen, but in the end it might not make all that much of a difference. Rumors suggest that Ada Lovelace is very performance hungry, meaning Nvidia isn’t taking advantage of the slight performance headroom advantage it may have had as it strives for maximum performance.
There’s also the possibility that AMD’s chiplet design could use different nodes, making node comparisons a largely meaningless endeavor. Its cards are also expected to increase power consumption.
Everything will become clear in time. The RTX 40 series cards are expected to launch sometime in the second half of 2022.
