Future of Core, Intel GPUs, 10nm and Hybrid x86



It has been difficult to miss the fact that Intel has vacuumed a lot of industry talent, which gives them a lot of experience. Renduchintala, Koduri, Keller, Hook and Carvill, are just to name a few. This new crew has decided to throw Intel out of the shell for the first time in a while, keeping the first in a new tradition for Intel Architecture Days. Through the five-hour presentations, Intel lifted the lid of the CPU core charts through 2021, next-generation integrated graphics, the future of Intel's graphics business, new chips built on 3D packaging technologies, and equal parts of the micro architecture for 2019 consumer processors. In other words, there are many of the things we've been missing for years. And now that Intel has such information, it's a lot to dig.

CPU Core Roadmaps

It's common for companies like Intel to ask questions about the press about what they like for announcements from Intel, Intel's competitors or other companies in industry. One of the answers I will never say is "road map". The roadmap is a simple document, but it allows a company to explain a part of its future plans in a very easily understandable way. It shows to the press, to customers and partners that the company has a vision beyond the next product, and that it expects to deliver in a rough cadence, hopefully with some markers on expected results or improvements. Directions are rarely taken as in stone either, with most people understanding that they have an element of fuzziness depending on external factors.

For this purpose, I have asked Intel to show roadmaps for many years. They used to be a common place, but since Skylake it has become a little dried up. In recent months, Intel has shown red data center roadmap, with Cascade Lake, Cooper Lake, and Ice Lake and the next generations. But for the Core family it has been a bit more difficult. Depending on which analyst you are talking to, a good number will point to some of the Skylake derivatives as holding points while the 10nm issues have been sorted out. But all we tend to hear about is the weak whisper of a code name potentially, which does not matter a lot.

So imagine my pleasure when we do not get a roadmap from Intel on CPUs, but two. Intel gave us both the core architecture map and the Atom Architecture Map for the next few generations.

For the high-performance Core architecture, Intel lists three new code names over the next three years. To be very clear here, these code names for the individual core micro architecture are not the chip, which is a major deviation from how Intel has previously done things.

Sunny Cove, built at 10nm, comes to market in 2019 and offers increased single-handed performance, new instructions and improved scalability. Intel went into more detail about the Sunny Cove micro architecture, which is in the next part of this article. To avoid doubt, Sunny Cove will have the AVX-512. We believe that these nuclei, when paired with Gen11 graphics, will be called Ice Lake.

Willow Cove appears that there will be a 2020 core design, probably also at 10nm. Intel lists the highlights here as a cache redesign (which may mean L1 / L2 adjustments), new transistor optimizations (production-based) and additional security features, probably referring to further improvements from new classes of side-channel attacks.

Golden Cove rounds out the trio, and is stuck in the 2021 segment of the graph. Process key here is a question mark, but we probably look at 10nm and or 7nm. Golden Cove is where Intel adds another piece of the serious pie on the record, with an increase in single-performance performance, focus on AI performance, and potential network and AI addition to core design. Security features also look like they get a boost.

The lower drive Atom micro architecture road map is on a slower cadence than Core micro architecture, which is not surprising given its history. To see how Atom has to fit into a number of devices, we expect there to be a wide range of features, especially from the SoC page.

The forthcoming micro architecture for 2019 is called Tremont, focusing on single-handed performance increases, battery life increases and network server performance. Based on some of the designs later in this article, we think this will be a 10nm design.

After Tremont, Gracemont becomes Intel as a 2021 product. As Atom is designed to continuously push both performance at the peak of its capabilities and low-efficiency efficiencies, Intel detects that Gracemont will have extra single-handed performance and focus on increased frequency. This will be combined with additional vector performance, which probably means that Atom will get some broader vector units or support new vector instructions.

Beyond this, there will be a future mont-kernel (and not month as shown in the picture). Here, Intel spits spitballing what this new 2023 kernel can have, for which the overall performance, frequency, and function listing is there.

As mentioned above, this is only the micro-architecture names. The actual chips these nuclei are in will probably have different names, which means a son's name for the Core micro architecture. At the incident, Intel stated that Cooper Lake wanted Sunny Cove cores in it.

Another aspect of Intel's presentations was that future micro architectures are likely to be disconnected from some process technology. In order to build some resiliency in the company's product line in the future, both Raja Koduri and Dr. Murthy Renduchintala explained that future micro-architectures will not be process-dependent, and the latest products will come to market on the best processing technologies available at that time. As a result, we are likely to see some of the Core designs on different production technologies.

Intel also went into some detail on the micro architecture of Sunny Cove.
