AMD’s future GPU architecture, RDNA4, is back in the news. This time, via Moore’s Law is Dead (video no longer available)
With RDNA4, AMD is simply abandoning the high-end sector. With its hypothetical RX 8000, there would simply be no RX 8900 XTX, for example, and we could count on a range similar to the RX 5000 in their day.
The biggest GPU of this generation would be able to offer performance equivalent to the Navi 31 used in the 7900 XTX. However, it would do so on a smaller, less complex chip… All mounted on a simpler PCB. All this implies an equally simplified heatsink, probably without the use of a steam chamber. Thanks to 4 nm etching, we can also expect a lighter chip in terms of compute units, which means lower overall power consumption. AMD’s decision to leave the high-end sector is understandable.
