AFAIK Phoenix also supports LPDDR5X-7500, some announced handhelds seemingly come with it, no idea on ultraportable laptops yet tho.
Judging by the frametime graph in those tests, which look way more spiky than 680M/RDNA2's.... 780M/iGPU RDNA3 is clearly still on early drivers in all these tests.
Also NBC's review is laughable. Only interesting tidbit is the Port Royal test (hybrid/ray tracing), where it's over 50% faster than last gen.
Seem the wait for fully fleshed out drivers and reviews of Phoenix IGP is still ongoing.
Here's 680M w/ DDR5-4800 vs LPDDR5-6400:

And we're supposed to believe it matters LESS for 780M, when it's not even using natively supported 5600 in all of these so called reviews, let alone LPDDR5 or 5X. lol
