Time to bring this up, Sisoftware leak the 7540U spec, which has also full 16M L3 cache and 6 cores:




It is clear that all Phoenix include 'PHX2' share same die, they are either full 8Core & 16M L3, or cut down/lesser cores&CUs version of it while still has full 16M L3. What else should be different is the clock.
You mean that PHX and PHX2 share the same die, or that all PHX SKUs share the same die, while all PHX2 SKUs share the same die as well (but another one than PHX)? Has this ever seriously been in question?

Asus ROG Zephyrus G14 review with Phoenix + RTX 4090.
Link

CB R23: 18131 points MT and 1789 points in ST.
Predecessor with 6900HS managed only 12606 points MT and 1562 points in ST, but 6900HX scored better in comparison 14120 points in MT.

P.S. That laptop is not that great. 125W limit for GPU means you don't need RTX 4090, RTX4080 will give you the same performance. Only 32GB DDR5 4800Mhz for 3999euro is very disappointing.

12% is barely any gain in your pseudo book..?.

We ll know more soon since NBC said they ll provide an in depth analysis of a 7940.
Depends on your outlook. We also get a 5% win sometimes defined as "demolish". Language, what happened to you?

Everyone (justme) expecting, "this time we'll have enough supply for notebooks, finally this time everything will be right, no delays!.
Reality is that AMD seems to be prioritizing these Deck rivals and leaving all the notebook market for Intel.

12% more performance with more than 100% Flops? (3.4TF vs 8,9TF)

As usual, you make nonsensical, irrelevant arguments.

The non sense is to say that there s no gain while there s a 12% gain, frequency is just as relevant as IPC since they use a smaller node and dont increase the thermals, at this rate you should compare a Zen1 to a Zen 4 and point the IPC improvement as only perf improvement.

Clutching at straws.

The straw is what you said at first, if we are to follow your logic, or rather lack of, Zen 4 SKUs are only 13% faster than Zen 3 based ones.

Edit : i remind you your sayings in case it s too foggy in your brain :


As expected, barely any gains for the iGPU over the 680M.

And the published graph displaying 12% average improvement :
