Although AMD has the AMD instinct MI250X... AMD hasn't updated the CDNA platform in a few years, so it tops out at 48 Teraflops of single precision performance.
The 7900XTX can peak at 61 Teraflops when boosting/47 Teraflops at base.
It's only if you need Quarter Precision/Double Precision or INT or the insane bandwidth HBM brings that CDNA is worth considering... Which isn't going to be applicable for many use-case scenarios.

Radeon Pro's have also been RDNA in the past, CDNA is reserved for the Instinct cards. Now, who knows how different RDNA and CDNA are, but I doubt they're much more different than Hopper-Ada or Turing-Volta despite CDNA ultimately coming from Vega. |
This.
Also they are very different.
Different wavefronts, SIMD width, RT cores and a re-tuneing of the entire uArch to better handle gaming rather than compute.

The 7800X3D is still a great chip for productivity.
- Many tasks these days can be offloaded to GPU's anyway like Encode/Decode/Transcode, so many people don't really miss a high-thread count CPU's if they leverage their PC's hardware appropriately.
