It’s a Cascade of 14nm CPUs: AnandTech’s Intel Core i9-10980XE Reviewby Dr. Ian Cutress on November 25, 2019 9:00 AM EST
The most profitable process node in the history of Intel has been its 14nm process. Since 2014, the company has been pumping out CPUs built on a variety of configurations of 14nm – slowly optimizing for power and frequency. We used to call these variants 14+ and 14++, but as the next process node isn’t yet ready, rather than draw attention to a soon-to-be 6-year old process, Intel just calls it all ‘14nm class’. The latest launch on 14nm is Intel’s new Cascade Lake-X processors: high-end desktop hardware that gives a slight frequency improvement over Skylake-X from 2017 but it also has the first round of hardware mitigations. Today we’re testing the best CPU of the new list, the Core i9-10980XE.
The Ups and Downs of Intel’s High-End Strategy
Way back in June 2017, Intel first launched its Skylake-X high-end desktop processors. The Core i7-7900X was a 10-core processor built using the smallest silicon die from Intel’s enterprise processor range. It was on sale for $999, a noticeable drop from the $1729 pricing of the 10-core in the previous generation, and fit into a market where AMD had just started to launch its 8-core Ryzen processors for half this price. The benefits over AMD at the time, as explained in our review, came down to new vector extensions, more PCIe lanes, more memory channels, and a higher rate of instruction throughput, all equating to more performance – if the cost didn’t frighten you away.
AMD quickly launched 16-core processors and then 32-core processors into the high-end desktop market, turning most of the areas in which Intel had been winning into wins for AMD. The 16-core 1950X/2950X and the 32-core 2990WX were able to stifle the usefulness of Intel’s 10-core offerings by being much more competitively priced. In response, Intel moved up another step in its enterprise CPU silicon, and started offering up to 18 cores to the high-end desktop market, first with the Core i9-7980XE at $1979, and then the Core i9-9980XE at the same price but with a small clock increase.
For 2019, both companies have kicked it up a gear. AMD now offers for its mainstream platform 16 cores built on TSMC’s 7nm process with the Ryzen 9 3950X, which has a recommended price of $749. It also has a fundamental performance per clock advantage, as well as a higher frequency than Intel's HEDT parts. This now means that Intel’s 18-core CPU, at $1979, competes against AMD’s 16-core CPU at half the price and with better efficiency.
Today’s Launch: Cascade Lake-X and the Core i9-10980XE
In order to be competitive, Intel is doing the only thing it can do, based on what it has in its arsenal: the new 18-core Core i9-10980XE that comes out today is going to have a tray price of $979. The new Cascade Lake-X processor, based on the same silicon as Intel's already-launched Cascade Lake generation of Xeon processors, comes with many of the same features introduced for those parts. In particular, this means the new Intel HEDT chips come with hardware protections for the first round of Spectre/Meltdown security patches. Intel is launching a range of processors, from 10-core all the way up to 18-core.
The Core i9-10980XE is an 18-core processor that has a base frequency of 3.0 GHz (same as the 9980XE) and a turbo frequency of 4.6 GHz (+100 MHz higher than the 9980XE) and a turbo max frequency of 4.8 GHz (+100 MHz higher than 9980XE). It can support up to 256 GB of DDR4-2933 with a quad-channel design, and has a 165W TDP.
|Intel Cascade Lake-X|
|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|
If we compare the top parts from AMD and Intel, we get an interesting differential.
|Intel vs AMD
|Core i9-10980XE||AnandTech||Ryzen 9 3950X|
|18 / 36||Cores / Threads||16 / 32|
|3.0 GHz||Base Frequency||3.5 GHz|
|4.6 / 4.8 GHz||Turbo Frequency||4.7 GHz|
|18 MB||L2 Cache||8 MB|
|24.75 MB||L3 Cache||64 MB|
|256 GB||DRAM Capacity||128 MB|
|165 W||TDP||105 W|
|$979 (1ku)||Price||$749 (MSRP)|
What we have here are two processors that are technically in different markets: AMD is making the ‘high-end desktop market’ for its processors go beyond $749, while Intel’s HEDT market is now from $569 to $979. This means that Intel does have an advantage in this price range for memory controllers and PCIe lanes. It is worth noting that Intel is not launching a 16-core processor in this family, to compete directly with AMD’s 16-core. The official reason is that Intel doesn’t see a need to insert a product between the 10940X and the 10980XE in that price range; however as most people have gathered, not having a direct competition product on core count saves Intel some expected embarrassment in performance comparisons.
With that being said, AMD is also launching its newest HEDT processors today as well. The AMD Threadripper 3960X (24-core) and AMD Ryzen Threadripper 3970X (32-core) are (just) derivative designs of their enterprise processors, but signify that Intel has nothing to compete in this 24-core and above space.
|Intel vs AMD
|18 / 36||Cores / Threads||24 / 48||32 / 64|
|3.0 GHz||Base Frequency||3.8 GHz||3.5 GHz|
|4.6 / 4.8 GHz||Turbo Frequency||4.5 GHz||4.7 GHz|
|18 MB||L2 Cache||12 MB||16 MB|
|24.75 MB||L3 Cache||128 MB||128 MB|
|256 GB||DRAM Capacity||512 GB||512 GB|
|165 W||TDP||280 W||280 W|
If we were to compare the 10980XE to the 3960X/3970X, it wouldn’t necessarily be a fair fight, with the AMD processors costing a good chunk more. But comparing the 10980XE to the 3950X is comparing a mainstream processor against HEDT, so the mainstream CPU automatically loses on most memory bound and PCIe bound tasks.
If we put up a price list for the updated product families, it shows the following:
|$2000+||28/56||Xeon W-3175X ($2999)|
|TR 3970X ($1999)||32/64||$1750-$1999|
|TR 3960X ($1399)||24/48||$1250-$1499|
|$900-$999||18/36||Core i9-10980XE ($979)|
|Ryzen 9 3950X ($749)||16/32||$700-$799||14/28||Core i9-10940X ($784)|
|$600-$699||12/24||Core i9-10920X ($689)|
|$550-$599||10/20||Core i9-10900X ($590)|

Santoval - Monday, November 25, 2019 - linkWait for the prices of both to adjust first.
Drumsticks - Monday, November 25, 2019 - linkI don't care about process nodes, as long as they're delivering competitive prices, core counts, and performance per core. Intel's not quite out of the game yet since AMD's HEDT goes higher than Intel's, but they've gotten smashed at the halo spot, and they won't be able to deliver on price and performance if they can't get something in order.
Braincruser - Tuesday, November 26, 2019 - linkNo they haven't been "smashed at the halo spot". The 3900X and 3950X are both beasts and both shred in most of the important benchmarks. For video rendering both the 3900x and 3950X hand out with both the threadrippers and the intels. You get 90% of the performance for 1/4th the price. 12-16 cores is also a very important number for programmers, since you have enough CPUs for compiling, and running 2-3 VMs comfortably.
Dolda2000 - Monday, November 25, 2019 - linkWhy is it that Intel gains so incredibly much more from AVX512 than AMD gains from AVX2?
In the 3DPM2 test, the AMD CPUs gain roughly a factor of two in performance, which is exactly what I'd expect given that AVX2 is twice as wide as standard SSE. The Intel CPUs, on the other hand, gain almost a factor of 9, which is more than twice what I'd expect given that AVX512 as four times as wide as SSE.
What causes this? Does AVX512 have some other kind of tricks up its sleeves? Does opmasking benefit 3DPM2?
Xyler94 - Monday, November 25, 2019 - linkBasically, AVX-512 is double the performance of AVX2 (or another way to see it, 256bit vs 512bits, which 512 is double 256). So anything optimized for 512 will be about double in speed from 256, even on the exact same processor.
Xyler94 - Monday, November 25, 2019 - linkTo note: That's a highly overly simplistic view of it, there's a lot more under the hood.
eek2121 - Monday, November 25, 2019 - linkWell that and the obvious point that AMD CPUs do not support AVX-512.
DanNeely - Monday, November 25, 2019 - linkAVX-2 is 256 bits wide, and thus only does have as much/instruction as AVX-512.
JayNor - Monday, November 25, 2019 - linkI believe for 10 cores and up there are dual avx512 units per core. You can see the dual avx512 units in the Execution Engine diagram at this link.
Also, cascade lake added dlboost 8 bit operations in avx512 to support ai inference convolutions.
Dolda2000 - Monday, November 25, 2019 - linkBut Zen 1/2 also has two 256-bit FMAs per core. And Intel also has two SSE units per core as well, so I don't see how that would explain the ratios.
