With someone in the press having broken their embargo earlier today, Intel is lifting the lid earlier than planned on their upcoming Cascade Lake-X family of processors for the high-end desktop (HEDT) market. Similar to the way Intel's Cascade Lake based Xeon Scalable processors are a further revision of their Skylake Xeons, offering clock speed increases and security fixes in hardware, the new HEDT processors will grant higher frequencies, more memory capacity, and better protection against side-channel attacks. The key numbers however are the big drop in Intel's pricing: Intel will be releasing its 18-core part, the Core i9-10980XE, for under $1000.

Intel Cascade Lake-X

Base All
TB2 TB3 TDP Price
Core i9-10980XE 18C / 36T 3.0 3.8 4.6 4.8 165 W $979
Core i9-10940X 14C / 28T 3.3 4.1 4.6 4.8 165 W $784
Core i9-10920X 12C / 24T 3.5 4.3 4.6 4.8 165 W $689
Core i9-10900X 10C / 20T 3.7 4.3 4.5 4.7 165 W $590
Skylake-X (previous generation)
Core i9-9980XE 18C / 36T 3.0   4.5 4.7 165 W $1979
Core i9-9940X 14C / 28C 3.3   4.5   165 W $1387
Core i9-9920X 12C / 24T 3.5   4.5   165 W $1189
Core i9-9900X 10C / 20T 3.5   4.5   165 W $989

This pricing is a significant shift in Intel's strategy, and a number of fingers will be pointed at AMD as having made this happen. Next month AMD is set to launch its 16-core Ryzen 9 3950X at $749, which will offer 16 PCIe 4.0 lanes for slots (+4 for M.2, +4 for chipset) and support for 128 GB of DRAM. So Intel needed something similarly speedy, but with more PCIe lanes and more memory support that they could offer for just a bit more, leading to the 10980XE for $979. Ultimately, the on-shelf price is often just slightly higher than tray price, so don't be surprised if retail prices land at around $1000. 

All the CPUs will support 256 GB of quad-channel memory (up from 128 GB), and have 48 PCIe 3.0 lanes (up from 44). Memory speed support is listed as DDR4-2933 for 1 DIMM per channel, and DDR4-2666 for 2 DIMMs per channel. All these CPUs have a TDP of 165 W, which Intel states will help the CPUs to turbo longer under Intel's recommended settings (as we know, consumer motherboard manufacturers like to ignore these anyway). All these CPUs are supported in X299 motherboards.

There is no 16-core in this stack, with Intel's official reasoning being that they assess the market with each generation and they don't believe there's a suitable price point for such a part when the 14C and 18C parts are so close. Most people will point the finger and say that no-16 core Intel part means no direct comparison with the Ryzen 9 3950X, which is something to think about.

Another point to note is that Intel has stopped this stack at the 10 core and no lower. This means that there will be no cross over between Intel's consumer processor stack and the HEDT stack, with users needing to spend just a little bit more from the Core i9-9900K/KF to reach up to the Core i9-10900X. It will be interesting to see where Intel's Core i9-9900KS fits in, although that still only has dual channel memory and 16 PCIe 3.0 lanes.

Intel lists Wi-Fi 6 and 2.5GbE support on these new processors - to clarify, Intel means external controllers here. For some odd reason when Intel says support, it could mean internal to the chipset or external via a controller; this is messaging I've railed against for a while, as it ends up confusing for enthusiasts, especially when this is an enthusiast platform. It does mean however that we get official information about Intel's 2.5GbE controllers, which we've been waiting on for a couple of years. Intel stated that these controllers will be ready at a later date, and more information to follow. (The controllers are currently listed on Intel's ARK database, but as 1 GbE controllers for some reason.)

These CPUs will have the same security mitigations as the Cascade Lake Xeon processors, with updated hardware mitigations for a number of side channel attacks. We are waiting to hear from Intel if the firmware that supports these processors will also have additional fixes in for Zombieload by default.

One question about this launch is surrounding Intel’s 14nm capacity. Within the last week, there have been reports that despite Intel’s best efforts and promises to match demand, and that Q3 and upcoming for Q4 is going to be busier than expected. We reached out to Intel last week for clarification, and the company said that the bulk of its capacity is focusing on the high-end processors in the market: the Xeon Scalable, the Core i9, Core i7, and Core i5. It will be interesting to see if launching another family of products is going to put additional strain on Intel’s capacity and demand.

With AMD's recent Zen 2 Ryzen 3000 series launch on 7nm earlier in the year, Threadripper 3 coming later this year, and Intel swinging another generation of 14++ into the high-end desktop market, Intel is going to have some tough times. Don't get me wrong, this pricing update from Intel is a good thing for users, especially those looking at implementing things like DL Boost to their workflow, but this market is suddenly turning very aggressive, and it will be interesting to see if Intel can be agile enough to keep pace.

Intel's Cascade Lake-X processors will be available in November. More details should be released nearer to launch.

    and what would you have done if the board you have, isn't capable at running at PCIe 4 speeds ??? my guess, you would be screaming at AMD

    You guess to much. And why would you even suggest such a thing? I am a grownup and I should be treated like one. They could, for instance, have a warning in the BIOS option that enables it. I already have warnings that say that they void my warranty if I click "Agree". Isn't that the same kind of thing only more benign since it doesn't do actual damage?

    Of course, I understand why they did it. I just don't agree with them doing it. And I'm rightfully mad at them. They get the upper hand and they start behaving like Intel. That's why it's wrong to be any company's fanboy. You just buy the best product at the moment you need it regardless of the company. That's how market economy is supposed to work. I was buying intel for 10 years and now I can finally buy and recommend AMD again. Let's see how long this lasts.

    kobblestown, still, warning or not, there would STILL be people screaming at AMD, and complaining that while their board doesnt work @ PCIe 4, they have 2 other friends who have boards that do. thats the point.. they are saving them selves from a PR nightmare, thats all there is to it, and while you feel it is wrong, look at it that way. there is just too many variables involved here to allow it on non x570 boards.
  • kobblestown - Monday, October 7, 2019 - link

    @Korguz, It's the same with overclocking. I don't see your point. No one ever promised PCIe 4.0 support on prev-gen boards. In the same way, no one ever promises specific results from overclocking. Yet, it's acceptable to allow it.
  • Korguz - Wednesday, October 9, 2019 - link

    and i dont see your point about not agreeing with amd about not suppporting pcie 4 on non x570. over all, its easier to overclock a cpu, as there is some OC headroom, but with a board, there are more variable involved. hence the term silicon lottery. who knows, maybe the board makers tested some of their boards, and it was too inconsistent, and told amd, and they dropped support...
  • The_Assimilator - Wednesday, October 2, 2019 - link

    So tell me, why doesn't AMD support more than 128GB then?
  • deil - Wednesday, October 2, 2019 - link

    Hell froze.

    "a number of fingers will be pointed at AMD as having made this happen"
    Saying that that is an understatement is an understatement itself. Would there even exist someone not believing that AMD made that happen?
  • Spunjji - Wednesday, October 2, 2019 - link

    I'd like to think that was a pointed understatement - no question that they've changed Intel's entire strategy!
  • umano - Wednesday, October 2, 2019 - link

    Now the ryzen 3950x is not that relevant unless amd lowers its price
  • Zizy - Wednesday, October 2, 2019 - link

    Vs 14C (I guess at same performance) AMD is a bit cheaper, has cheaper boards available and comes with lower TDP. PCIe is roughly comparable, depending on your needs (24x PCIe 4.0 vs 48x PCIe 3.0), while Intel wins in memory capacity and bandwidth.
    Plus AMD has TR to compete with that.
