Conclusion

This new processor, armed with never-before-seen performance in multi-threaded benchmarks, is also equipped with never-before-seen pricing...

Intel holds a commanding performance and market-share lead in virtually all CPU segments. Nowhere is this hegemony more keenly felt than in the high-end desktop (HEDT) space, where wave after wave of Core i7 processors' main goal is to simply improve upon their predecessor. AMD, for the time being, is conspicuous by its absence.

The chip giant usually updates its real enthusiast offerings some time after the mainstream has had its fill. The latest architecture, codenamed Skylake, has been infiltrating the desktop and mobile market for a good year now but is yet to be seen in the HEDT environment.

Rather, following on from the latest round of performance Xeons chips, Intel is updating this niche part of the market with a quartet of Broadwell-based processors that, like their Skylake cousins, adopt the Core i7 6-series nomenclature.

Chief among these performance protagonists is the Core i7-6950X. Intel has increased the core count from eight on the previous generation to 10 in this instance, offering an immediate boost to applications that are greedy for cores and threads. Faster official memory support and a minor clock-for-clock boost by dint of the Broadwell architecture firmly installs the Core i7-6950X as, quite simply, the fastest consumer processor to date.

Yet Intel knows that those who genuinely desire the best-in-breed chips oftentimes have the ability to pay. This new processor, armed with never-before-seen performance in multi-threaded benchmarks, is also equipped with never-before-seen pricing. The cost for such prowess is a wallet-stripping $1,569. This is Intel playing fast and loose with enthusiast's wants and desires.

Yet, looking at it from a whole ecosystem point of view, simply throwing more cores at the PC problem isn't the overarching panacea that Intel would perhaps like you to believe. Games barely benefit from running above a comparatively cheap and cheerful Core i7-6700K Skylake processor, so other than some personal satisfaction of owning the best of cutting-edge CPU hardware, the Core i7-6950X is, for most, financial profligacy at its finest.

There's a new consumer CPU performance king in town, but obtaining an audience with it requires some serious coinage. If you want the best, you had better be prepared to pay, handsomely, for the privilege.

How disappointing :( I guess there *may* be some kind of justification in getting this top of the line one due to the extra cores (if for some reason you're stuck in a single chip environment) but it looks like the rest of the line won't be any improvement over ye olde Haswell-E.
In the testing methodology table, you have put 10/20 cores/threads for the 5960X (instead of 8/16).
Hexus, are you sure about this bit?

For reasons that still remain a mystery, Intel decided to hamstring the Core i7-5820K, for gamers at least, by limiting the number of PCIe lanes emanating from the processor from the usual roster of 40 down to 28. The same mistake is not made on the Core i7-6800K, which retains all 40 lanes, meaning its $412 renders the next chip up, the 6850K, moot for the savvy purchaser.
Other reviews I've read say the 6800k is cut to 28 again:

When Intel introduced Haswell-E, it experimented with a new type of product separation: it also varied the number of CPU-host PCIe lanes among the SKUs. This practice continues in Broadwell-E, in an almost identical fashion. The lowest end CPU has 28 PCIe 3.0 lanes, capable of three-way GPU setups (and no 2x16 setups), while the other processors have a full 40 PCIe 3.0 lanes, allowing for four-way GPU setups or different combinations therein.

Hexus, are you sure about this bit?

you are right, the 6800k has 28 PCIEx lanes.
I doubt Intel intended this for gamers somehow…
