How is it possible all internals got beefed up even doubled but its only 10%-20% at most

everyone's in disbelief!
We are in the era of diminishing gains.

In 2018 when ARM unveiled the Cortex A76 with a colossal >50% IPC gain, they prophesied that going forward there will be only smaller gains. It has proved true. We haven't seen such a large IPC gain from them since.

MT score of GB6 is irrelevant.
Maybe overall, especially when comparing two different products. But comparing the exact same product against itself can provide some value. The core configuration and uarch is unchanged so differences in score can be attributed to more specific differences like boost clocks and memory.

The 'consensus' - if you will - in this forum is that GB6 multi-core score is useless as representative of your typical multi-core workload.

7900X priced at $458 while 9900X at $557.

Should get delivered in max 4 days, if I pull the trigger, which I won't

4800MT/s for the 9600X vs 7600MT/s for the 7600X and GB6 is very membw sensitive.

I expect a 13-14% score difference using the same memory.
For some unknown reason, a quite good result for 9600X posted after the above run, different system. This one appears to be hitting and maintaining full ST boost at least, but dont know if this is PBO or what.

Makes absolutely no difference to the Single Core score:

At 6400 MT/s you might be running FCLK:MCLK at a ratio of 1:2.
In general best GB6 runs are either running DDR5-6000 (likely 1:1 ratio), or DDR5-8000. The reported clocks are very similar to your run.

ST score isn't as memory bandwidth sensitive, sure, but it still matters, so I wouldn't compare two CPUs with different memory setups on something as variable as gb6.

Anyway, only a few days left to wait to see how DOA GNR is.

The reality is always more complex, no matter what the consensus is. This has been discussed ad nauseam. And this proves that no matter what technical arguments are given, someone will come and make the same approximative claim again and again.

If you want to see perfect scaling, pick GB6 ray tracer score, it scales about as well as Cinebench.

And then people wonder why more and more knowledgeable people are leaving the forum.
How is "do not treat different memory configs as an apples-to-apples comparison" a controversial statement.

edit: and by "knowledgeable" I don't mean myself -- I'm far from it.
