The new details include the final clock speeds for the upcoming chips and we also have some more details regarding the launch dates for the XCC (Extreme Core Count) processors.

Intel Core X “Skylake-X” Full Specifications, Clock Speeds Detailed – 18 Core Base Clock at 2.6 GHz, Boost at 4.4 GHz

First of all, there are a total of seven Skylake-X chips that are announced under the Intel Core X brand. These include the Core i7-7800X, Core i7-7820X, Core i9-7900X, Core i9-7920X, Core i9-7940X, Core i9-7960X and the Core i9-7980XE. The first three processors are already out in the market but the rest will see launch in the coming months. First up, we will be looking at the 12 cores model that is expected to launch on 14th of August. The remaining three chips will launch during October 2017.

The Core i9-7980XE: Intel’s Unbeatable Flagship ‘Skylake-X’ Processor with 18 Cores / 36 Threads – 2.6 GHz Base, 4.2 GHz Boost Clocks

Priced at $1999 MSRP (you are paying $111.11 per core) and featuring the Skylake-X architecture, this beast of a processor will be the ideal go-to processor for content creators that want the maximum throughput in terms of rendering performance. This is a processor that will almost certainly be overkill for gaming (unless you are running some sort of CaaS enterprise).

It has 18 cores and 36 threads which makes it an absolute juggernaut and beefier than AMD’s 16 core Ryzen Threadripper 1950X. Core clocks for the Core i9-7980XE are maintained at 2.6 GHz (base), 4.2 GHz (Turbo Boost 2.0) and 4.4 GHz (Turbo Boost Max 3.0). The CPU features an L2 Cache of 18 MB (1 MB per core) as well as an L3 cache of 24.75 MB. Quad channel DDR4 up to 2666 MHz is. The processor has a TDP of just 165W and is housed on the LGA 2066 socket like the rest of the lineup.

The Core i9-7960X: Intel’s 16 Cores / 32 Threads Offering That Will Take On AMD’s ThreadRipper Platform – 2.8 GHz Base, 4.2 GHz Boost Clocks

Priced at $1699 and featuring the Skylake-X architecture, the Core i9-7960X has the exact same core count as AMD’s highest end Threadripper CPU, the Ryzen Threadripper 1950X and that’s not a coincidence. Intel has put this particular CPU to take on the Threadripper platform in all its glory (and core count) and features the Turbo Max 3.0 technology just like its bigger brother.

Core clocks are maintained at 2.8 GHz (Base), 4.2 GHz (Turbo Boost 2.0) and 4.4 GHz (Turbo Boost Max 3.0). It will feature an L2 Cache of 16 MB (1MB per core) as well as an L3 cache of 22MB. Memory support is the same for all Skylake-X processors and remains quad channel DDR4-2666. The wattage is also locked at 165W. At the moment, the base clock of this variant is unknown.

The Intel Core i9-7940X: Intel’s 14 Cores / 28s Thread Processor For Serious Content Creators – 3.1 GHz Base and 4.3 GHz Boost

Priced at $1399 (you are paying $106.18 per core) and featuring the Skylake-X architecture, the Core i9-7940X is one of the higher end offerings of this lineup and aimed dead center at content creators. Since no gamer is going to need more than 8 cores (and even that is debatable!) this entire lineup is targeted at the content creation industry which needs to do compute intensive tasks.

The Core i9-7940X features a base clock of 3.1 GHz (Base), 4.3 GHz (Turbo Boost 2.0) and 4.4 GHz (Turbo Boost Max 3.0). It features 14 MB of L2 cache as well as 19.25 MB of L3 cache. All other specs including quad channel DDR4 and TDP (165W) remain the same.

The Intel Core i9-7920X: Intel’s 12 Cores / 24 Threads Processor for Content Creators – 2.9 GHz Base, 4.3 GHz Boost

Priced at $1189 (you are paying $99.083 per core) ) and featuring the Skylake-X architecture, the Core i9-7920X is one of the more value oriented offerings for VR and content creators. The Intel Core i9-7920X will be Intel’s first 12 core, high-end desktop processor. It won’t be the flag ship of the Core X family but it will still hold its own in terms of price and performance.

As far as specifications are concerned, the Intel Core i9-7920X packs 12 cores and 24 threads. The chip features a base clock of 2.9 GHz and a boost frequency of 4.0 GHz. We can tell that not all the cores will be operational at the 4.3 GHz boost clocks and 4.4 GHz for Turbo Boost Max 3.0. The chip will also feature Turbo Boost Max 3 technology which will boost even further. In terms of cache, the chip features a total of 16.5 MB of L3 and 12 MB of L2 cache. Combining the cache, we get 28.5 MB of total cache on board the chip that Intel terms as smart cache. The chip will support quad channel memory and feature 44 PCIe lanes for discrete GPU and NVMe based storage devices.

While it’s good to finally know the clock speeds, the frequencies themselves are much lower than what we would have called ideal for many workloads. As we have seen, the Ryzen Threadripper chips have higher clock speeds and similar core counts but Intel may be going a different approach with the Extreme Core Count models. Instead of focusing at serial workloads, Intel is going to aim and market these chips with as increased parallelism.

The reason is that Intel has already shown in their slides that these CPUs are designed for mega-tasking, a relatively new term in the industry that started with the Core i7-6950X. But mega-tasking is the future as people building such high-end systems with massive core counts aren’t just doing so for gaming. These PCs are better for content creation, development and heavy workloads and such tasks don’t require higher clock speeds as much as they take benefit of moderate yet stable clock speeds and Intel Core X can achieve a comparable clock speed to Threadripper in high core optimized workloads as we will detail in a future article.

For now, Ryzen Threadripper seems like a very powerful and cost effective price while with Intel, you seem to be paying more but getting a slightly good advantage in terms of single core boosts, lower TDPs and a more refined architecture.
