Intel officially reveals the specification of their high-end X299 CPU lineup

Those are some high boost clock speeds given the core counts of these CPUs

When Intel announced their Skylake-X CPU lineup, their highest end 12-18 core SKUs were listed without their full specifications, leaving many curious how much single-threaded performance the company planned on offering when compared to their lower core count offerings.  

Many assumed that Intel would have to sacrifice core clock speeds to maintain a low TDP with their 12-18 core parts, though Intel has done a great job to ensure that they are able to achieve high boost clock speeds that will allow Skylake-X to easily power through both single-threaded and heavily multi-threaded tasks.  

We can see that even with increased core counts, Intel has been able to offer some high turbo boost frequencies on their high core count CPU offerings, offering Turbo Boost 3.0 speeds of 4.4GHz, which is a high boost clock speed for any modern CPU. Even so, the base clock speeds of higher-end models do see a downward trend as core counts increase, especially after Intel's CPUs reach a higher TDP of 165W.

What we can see here is that Intel's higher core count offerings will not be making any major sacrifices when it comes to single-threaded performance, which is great news for consumers.  

It will be very interesting to see how AMD's upcoming Threadripper series of CPUs will compete with Skylake-X, given their more affordable pricing per core and the 64 available PCIe 3.0 lanes that are present in every Threadripper CPU.

High-end overclockers will also be interested in how well Intel's X299 platform copes with 18-core CPU overclocking, given the recent thermal controversies surrounding the VRM temps of motherboards in AVX heavy tasks.

Intel has announced that their 12-core i9 7920X will be available on August 28th, with their higher-end 14-18 core models becoming available to purchase from September 25th.

I would love to see a Threadripper 1950x versus the Intel 7960x comparison. I really am leaning AMD as its $700 cheaper if the performance is there.

I honestly don't understand when the top end x299 processors only have 44 PCI/E lanes.

OK, those prices are insane. The Ryzen will be slower dude, BTW. Well, that's if the Intel is not telling fibs and actually boosts to those clocks on every core. Which I doubt. I would imagine the actual number is around 4ghz, so it could be close. You would need to overclock the Intel and risk fryin' tonite.

Either way I can absolutely guarantee to you right now that it ain't worth no $700 for what could equate to like 300mhz more clock speed.

$1699. LOL.Quote

From what I can see, the 12-18 core models are a response to Threadripper, effectively Intel using their X299 high core Xeon CPUs with consumer branding and an unlocked multiplier.

The simple answer for the PCIe lane problem is that Intel did not consider it an issue, and even with new CPUs they could not get motherboards to magic up more usable PCIe lanes current designs. IE, X299 is designed with 44 lanes in mind, so that cannot change until the next socket upgrade.

Turbo boost 3.0 is only for two of the CPUs cores.Quote

Yeah that's right. Doesn't it pick like the best cores or something like that?Quote

Aye, supposedly Intel chooses the two best cores with Skylake-X to maintain the lowest TDP/thermals they can.

With Skylake-X the Turbo 3.0 boost applies to 2 cores and not just 1.Quote
