You are comparing 2 chips to a single chip and trying to argue against the claim that the single chip is the fastest yet.

I'll humour you however.

Your Xeon turbos to 3.1 if only 1 core is stressed, but it's all core boost is 2.4 as per https://www.pugetsystems.com/blog/2015/07/09/Actual-CPU-Spee...

I don't see how your 10core part boosting to 2.4 Ghz is "much faster in the day to day development tasks" given that it's 2 CPU architectures behind and clocks at almost half the 4.0 Ghz achieved by the 7900x (all-cores boost).

But even a pair of those 10 cores is probably slower (caches are not shared, all-core boost almost half while roughly 5% slower in IPC performance due to the jump from Broadwell to Skylake).

So I don't think you're actually trying to argue that this isn't the fastest chip yet, but that it's a bad deal compared to looking around and buying some used server parts.

And yes, that's a better deal, but also a used i9-7900x is a better deal than a new i9-7900x...

The link I provided contains detailed benchmark results of the mentioned system against 6950x. In quite a few workloads, e.g. SPECwpc, it is beating 6950x by up to 42%. See page 4. The maths is really simple here - i9-7900x need to beat i7-6950x by 40% to match that performance.

i9-7900x is _NOT_ the fastest chip in the world, not even the fastest intel chip. Consumer/server difference is purely a marketing thing, my Xeon based workstation running CS:GO on daily basis is not a server.
