XMG Neo 17 E23 vs Neo 16 E25, am I right to be disappointed?

[MiSJAH]

So I "upgraded" from the Neo 17 E23 with I9-13900HX and RTX 4090 to the Neo 16 E25 with Ultra 9 275HX and RTX 5090. 

Timespy score from Neo 17 - 23644
Timespy score from Neo 16 - 24474

Detailed comparison.

So it looks like the 5090 is ~11.6% more powerful than the 4090 but the Ultra 9 is 33% less powerful than the I9-13900HX.

Advice, suggestions, help please.

Time Spy is an older benchmark and doesn't scale well with Core Ultra CPUs.

 

Furthermore, memory makes all the difference in CPU scores, and it seems that with the i9-13900HX you used 6400MT/s modules while with the 275HX you used 5600MT/s.

 

With VBS disabled, stock memory (5600MHz CL46) and stock CPU, I reached up to ~17700.

 

Everything remained the same, but with CPU undervolting and an IETS GT600, the CPU score increased to ~18500.

 

And finally, with memory adjusted to 6400MT/s CL36, I now reach up to ~21900.

 

I've seen scores of ~24k with faster memory.

 

Regarding the GPU, its score with the 4090 is good, slightly below its maximum overclocking potential (up to ~24.5k), but its score with the 5090 is not so good...

 

With a well-tuned overclock, it should be able to exceed 27k and perhaps even 28k with a good cooling pad

OK, so no undervolt and CC Performance profile set to Overboost/Overboost extreme I hit 17969 CPU score as a custom run.

What profile are you using in CC?

Try Custom with maximum settings / fan boost and Overboost Extreme.
