1T on par with 7950X. nT on par with 5950X.

The GPU is very powerful.
51% PPW, we are so back Radeon bros.
Now of course that is one bench and not iso-config but regardless I'd say about 35% PPW vs RDNA3 iso-node sounds about right. With the PPW advantage increasing with power.
RDNA4 should be easily 50% RDNA3 PPW.

This is just all about sticking it to Intel, as, really they can; these chips are not expensive to produce and you get a lot of PC even with a B650 board.
Given the fact Zen4 is more or less equal in performance to Raptor Lake and Zen5 being supposedly only 15 percent above it on average, i would not call this "sticking it to Intel".
Not saying its not fine, but its clearly just made with intention to stay relevant, at best remain slightly ahead, to provide something more enticing than Intel, but only to the point it does not have effect on their margins. That is not "sticking" in my book. That fabled 40 percent IPC bump might have been. Core count bump across the board (as the result of more cores per chip) would have been. But this, nah.

So increasing CU and getting 36% is quite impressive, especially if the change in process technology is not big.
And especially if BW is still limited by the RAM. It must be seen, if that is the average improvement, or a single data point. What it is interesting is that at the same power, the 890M has +51% improvement in Timespy score respect to the 780M.

Is it really?
so lets compare at "sane" levels for mobile CPU
54w Time Spy:
2791 / 4221 = 1.51

Phoenix shows diminishing returns if it is allowed to go up to 72W almost as it it was a desktop APU:
72 / 54 = 1.33 power increase, 3218 / 2791 = 1.152 score increase

Imaginary Phoenix with glued on 4CUs that magically do not consume any energy (still at 54W):
2791 * 1.33 = 3712

Still can't beat or even match it...
3712 / 4221 = 1.13 >> something in RDNA 3.5 consumes significantly less power (might not be the CUs...)

Didn't know that, thanks!
Another thing is that GPU's primary way of increasing performance is more parallelism, which you cannot do for CPUs, because graphics are massively parallel. So the main focus is increasing more shaders and make sure they scale well.

Regardless you are limited by transistor count and power use, and with modern advanced power management, oftentimes you don't get what you added.

The thing is, TS graphics score correlates perfectly with dGPU gaming performance, which is not the case with APUs, if the claimed gain of 36% is true.
Btw, that promo said
Combined with LPDDR5x 7500 MT/s memory, the memory bandwidth is simultaneously increased
780M's shared memory run at what, 5200mt/s?

Not sure if frequency is reported correctly.

It looks like RDNA3.5 is a bigger increase over RDNA3 then RDNA3 was over RDNA2.
