AMD’s new RDNA3 is on the cusp of its launch and full specs have yet to be released. Leaks have already determined the likely SKUs AMD RDNA3 will have, alongside some minor specs and performance behavior. A few months ago, RedGamingTech discussed some leaks about AMD’s flagship GPU, one such topic being its intended release date, which ended up being true.
RedGamingTech also commented on other leaks, such as the expected performance and TDP of the RX 7000 series. According to the rumors, Radeon RX 7000 series cards powered by the RDNA3 Navi 31 chip will have a TDP set between 375W and 450W.
This is a major increase when compared with the power consumption of the RX 6000 series, which didn’t go higher than 300W. On the Green Team’s side, Nvidia’s RTX 4090 boasts a TDP performance of 450W.
AMD RX 7000 series specs
The Radeon RX 7000 series will be built using AMD’s brand new RDNA3 microarchitecture known as Navi 3x. It will come in three different variants: Navi 31 for their flagship high-end series, Navi 32 for their high-end/midrange, and finally, the Navi 33 for the RX 7000 series midrange/low-end.
The Radeon RX 7900 GPU will be powered by the Navi 31, which will feature up to 96 compute units, a 384-bit wide memory bus, and 24GB of VRAM. Below is a full specs list of what to expect out of AMD’s RDNA3 architecture:
| Architecture | Navi 31 | Navi 32 | Navi 33 |
| Graphics Cards | RX 7900 XT, 7800 XT | RX 7700 XT, 7600 XT | RX 7500 XT, 7400? |
| Process Technology | TSMC N5+N6 | TSMC N5+N6 | TSMC N6 |
| Compute Units | 96 | 60 | 32 |
| GPU Cores (Shaders) | 12288 | 7680 | 4096 |
| Infinity Cache | Up to 192MB / 96MB | Up to 64MB | 32MB |
| VRAM (GB) | 24 / 12 | 16 / 8 | 8 |
| VRAM Bus Width | 384 | 256 | 128 |
| Bandwidth (GBps) | 864 | 576 | 288 |
| TDP (watts) | 300-450 | 200-300 | 75-150 |
We also know that AMD, for the very first time, will be utilizing GPU chiplets with RDNA3, named GCD (Graphics Chiplet Die) and MCD (Memory Chiplet Die), with some of them using a TSMC N5 node process. For now, the majority of the information on RDNA3 is based on speculation and leaks, so we can’t confirm anything just yet. We will have to wait until AMD decides to divulge more on its highly anticipated RDNA3 architecture in the weeks to come.
