Yeah, IIRC you don't need a custom hardware to make use of HRTF. The Tempest thing is that it's a optmized CU for audio task (that accordingly to Cerny involve a lot of multiplies).CFPU2 seems to be the equivalent to Tempest. It is a programmable audio processor and can also do HRTF and other parts not mentioned here.
What is not clear to me, is the "greater SPFP HW math than all 8x CPUs [cores?] in Xbox One X": On one hand it does not appear to be written by a technical person (because of the "8x CPUs", which is technically incorrect) and on the other hand CFPU2 alone appears to have less SPFP performance than the 8x CPU cores. So my personal feeling is that the other audio processors mainly used for decoding (which Sony should have as well), were converted to a SPFP metric and added to that Xbox One X comparison. I said before that I am not a big fan of Xbox's marketing and I think this is another one of this "not really wrong" but "intentionally missleading" in order to make it sound better.
To be honest, even if the audio chip on XSX is as good as the Tempest, they don't seem to put the same effort into HRTF as Sony. Sony mapped hundreds of HRTFs, are clearly making it part of the system itself and even filled a patent for an HRTF database.
Expect the HRTF calibration test to be one of the first things you'll do when turning on your PS5 later this year.
