Intel announced today in its Q2 2020 earnings release that it has now delayed the rollout of its 7nm CPUs by six months relative to its previously-planned release date, undoubtedly resulting in wide-ranging delays to the company's roadmaps that could cause the company to lose ranks in our CPU Benchmark Hierarchy. Intel's press release also says that yields for its 7nm process are now twelve months behind the company's internal targets, meaning the company isn't currently on track to produce its 7nm process in an economically viable way. The company now says its 7nm CPUs will not debut on the market until late 2022 or early 2023.
Here's the snippet from Intel's press release:
"The company's 7nm-based CPU product timing is shifting approximately six months relative to prior expectations. The primary driver is the yield of Intel's 7nm process, which based on recent data, is now trending approximately twelve months behind the company's internal target."
On the earnings call, Intel CEO Bob Swan said the company had identified a "defect mode" in its 7nm process that caused yield degradation issues. As a result, Intel has invested in "contingency plans," which Swan later defined as including using third-party foundries. The company will also use external third-party foundries for its forthcoming 7nm Ponte Vecchio GPUs, the company's first graphics chips. Ponte Vecchio comes as a chiplet-based design, and Swan clarified that production for some of the chiplets (tiles) will be outsourced to third parties. Swan noted the GPUs will come in late 2021 or early 2022, portending a delay beyond the original schedule for a 2021 launch in the exascale Aurora supercomputer.
Intel's first 7nm server CPUs (Granite Rapids) will arrive in 2023, which is later than listed in earlier roadmaps that projected a launch in 2022. That timeline is concerning in the face of AMD's continued execution with its EPYC data center chips – AMD's roadmaps outline its 5nm Genoa processors coming to market before the end of 2022. Swan also said that Intel's first 7nm processors will debut for the client market, meaning chips targeting either desktop PCs or laptops. Intel's first 10nm desktop CPUs, Alder Lake, will arrive in the second half of 2021.
For perspective, rival foundry TSMC plans to be on the 3nm node in the same time frame as Intel's new schedule for 7nm. Intel clearly isn't pleased with its execution on the 7nm node, as an embattled Swan remarked that "And we feel pretty good about where we are, though we’re not happy. I’m not pleased with our 7nm process performance" at the end of the call after a bruising question and answer session with analysts. Swan also said "we have root-caused the [7nm] issue and believe there are no fundamental roadblocks," and that the company would provide further updates at an upcoming Architecture Day.
Swan said the company had a built-in buffer in its roadmap to account for process node delays. That accomodation comes as a result of hard-learned lessons from the company's incessant 10nm delays. Intel says it will use its advanced packaging technologies, which allow it to mix and match components produced from external sources with its own chips, to help reconcile the six month delay to its 7nm processors with the year-long delay to its internal 7nm yield projections. Swan also noted that Intel could use third-party foundries for entire chip designs. In the past, Intel stated that it would also enable newer architectures to be portable to older nodes, so it's plausible that Intel could resort to back-porting some architectures as part of its contingency plan.
The 7nm delay reflects yet another setback as Intel still struggles to overcome the multi-year yield issues it has encountered with its 10nm process. Those delays have allowed its competitors, like AMD, to wrest the process node leadership position from Intel for the first time in the company's history. That's triggered a price war in the market as Intel fights a true x86 competitor with a better node, not to mention Amazon's new Graviton 2 ARM chips based on TSMC's 7nm node. Apple also recently announced that it is transitioning from Intel's chips to its own ARM-based 7nm silicon. The 7nm delay also exacerbates the recent news that rock star chip architect Jim Keller, who was a key part of a team effort to revitalize the company's roadmaps, has left the company.
Intel CFO George Davis has previously indicated that the company's process tech would lag its its competitors until 7nm arrived in 2021, and that the company would regain the lead with its 5nm process at an undefined time:
"So we bring a lot of capability to the table for our customers, in addition to the CPU, and we feel like we're starting to see the acceleration on the process side that we have been talking about to get back to parity in the 7nm generation and regain leadership in the 5nm generation."
That plan to regain a competitive footing has now obviously shifted due to the 7nm delay. Intel had planned to speed the delivery of its 7nm node to offset the underperforming 10nm, which it said would not perform as well as other nodes. At the time, Davis noted that the company was trying to be clear with investors about the impacts of 10nm on the company's gross margins: "...but the fact is that I wanted to be clear what was happening during the 10nm generation. The fact is, it isn't going to be as strong a node as people would expect from 14nm or what they'll see in 7nm."
In regards to the 10nm node, Davis commented: "As we said back at our analyst day in May of 19: Look, this isn't just going to be the best node that Intel has ever had. It's going to be less productive than 14nm, less productive than 22nm, but we're excited about the improvements that we're seeing and we expect to start the 7nm period with a much better profile of performance over that starting at the end of 2021."
"Also, we were at a time when in order to regain process leadership we had to accelerate the overlap between 10nm, 7nm, and then 7nm and 5nm, so the cost that you're absorbing, starting in particular in 2021, you’ve got this intersection of the performance of 10nm, the investment in 7nm, and were also well into starting the investment in 5nm: All of those elements just combine to impact gross margin."
Today Intel said that it plans to increase its shipments of 10nm chips by 20% over its prior projections, so it appears the company's 10nm plans have shifted out of necessity. Intel's new plan centers on gaining another 'full node' of performance from its current 10nm node, meaning 10nm may have longer legs than the company expected when it announced last year that it would accelerate 7nm production. Intel pulled off a similar feat with its 14nm processors through a series of "+" revisions that added incremental performance improvements, so it does have a track record of successful inter-node improvements that could help it remain competitive until it can correct the issues with its 7nm process.
Intel has also traditionally used third-party fabs, currently to the tune of ~20% of its production, for low-margin, non-CPU products built on trailing-edge nodes. Intel's new plans to more aggressively leverage external fabs could result in it using other fabs for its core logic, like CPUs and GPUs, which the company hasn't done in the past. As Swan noted, that will present challenges in maintaining attractive ASPs for Intel's products, especially given the scale of its production needs. Ultimately, Intel could also face significantly reduced margins if it outsources significant portions of its fabrication of high-margin products, like CPUs, to third parties. Relying upon an outside vendor for leading-edge node production also incurs more risk in terms of supply assurance as Intel could be forced to compete with deep-pocketed rival semiconductor companies, like Apple, Nvidia and AMD, among others, for production capacity.
Looks like Intel may not have much for people to get excited about until 2022.
I think moving to EUV is a huge change and they are having a hard time getting the yields up on EUV. They were being too optimistic once again. You know this is why TSMC did the initial 7nm where only some up front processes were 7nm rest was 12-14nm. Then they improved that process my having more processes use 7nm. Now TSMC are using EUV for 5nm. This is the lesson Intel needs to learn, baby steps on node improvements going forward so its small evolutionary steps not revolutionary steps. Things are way to freaking complicated now to make big leaps. This is why TSMC is ahead now. This is the missing lesson.
Slow & steady wins the race!
TSMC, was improving incrementally, while Intel decided to shoot for as far as they can like Icarus.
We all know what happened to Icarus wings.
Listening to Intel 2Q Earnings Conference...
Intel is touting that they have the most technically advanced packaging technology... While their new 7nm process is technically screwed.
I could be wrong but that seems like wrong priorities </s>
Wow, that was some BS response from Swan (Intel CEO).
I guess that was expected from an MBA instead of an engineer.
Brian Krzanich was a Chemistry Major and worked as a process engineer in Intel's Fab's.
He worked his way up to CEO position, but he's still a Chemistry guy at the core.
Far more useful then Bob Swan who's just a glorified Middle Manager with a MBA degree.
