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



It was hard to miss the fact that Intel has been a vacuum of a lot of talent in the industry, which brings with them a lot of experience. Renduchintala, Kodori, Keller, Hawk, and Carvill, are just a few there. This new team decided to break Intel out of its shell for the first time in a while, holding the first in the new tradition of Intel Architecture Days. With the five presentations, Intel raised the lid on the core CPU roadmap to 2021, the next generation of integrated graphics, the future of Intel's graphics business, new chips built on 3D packaging technologies, and even parts of the 2019 microarchitecture The consumer. In other words, that's a lot of the things we've been losing for years. And now that Intel has these kinds of discoveries again, there's a lot to dig.

Content List

Intel covered a large amount of land on the day of architecture, which we divided into the following categories:

  1. CPU core and opaque roadmap, about 10nm
  2. Sonny Cobb microarchitecture
  3. Next Generation Gen11 Graphics
  4. Intel Demonstrates Sunny Cove and Gen11 Graphics
  5. Beyond Gen11 Graphics: Announcing XGod Brand Graphics
  6. 3D PACKAGING WITH FOVEROS
  7. Intel 's First Fovoros and First Hybrid x86 Processor: Core Plus Opaque at 7 W at 10nm
  8. Ice Lake 10nm Xeon
  9. Intel did something really funny: Q & A with Raja, Jim, and Mary

The core roadmap

It is common in companies such as Intel to ask the press what they enjoy about the announcements made by Intel, Intel's competitors, or other companies in the industry. One of the answers I'll never tire of saying is & # 39; road maps & # 39 ;. The road map is a simple document, but it allows the company to explain some of its future plans in a very easy way to understand. It shows the press, customers and partners that the company has a vision beyond the next product, and that it expects to deliver at a rough pace, hopefully with some markers on performance additions or expected improvements. The road map is rarely absorbed as determined in stone or, with most people realizing that they have an element of blurry depending on external factors.

To this end, I have been asking Intel to present a road map for years. They were once a common place, but since Skylake, it has a dried species. In recent months, Intel has presented rough road maps with Lake Cascade, Cooper Lake and Lake Ike and future generations. But for the core family it was a bit more difficult. Depending on which analyst you're talking about, a good number will point out some Skylake derivatives as being holding points while problems with 10nm have been sorted out. But still, all we tend to hear about is a faint whisper of a potential code name, which does not mean much.

So imagine my pleasure when we do not get one Intel roadmap in processors, but two. Intel has given us the core roadmap and road map architecture of Atom for future generations.

For the high core architecture, Intel introduces three new names over the next three years. To be very clear here, these are the previous names for the individual core microarchitecture, not the chip, which is an important departure from how Intel previously did things.

Built on 10nm, the Sunny Cove will hit the market in 2019 and offer improved single-threaded performance, new instructions and improved scalability. Intel goes into more detail on Sonny Cobb's microarchitecture, which is in the next section of this article. To avoid doubt, Sonny Cobb will be AVX-512. We believe that these cores, when paired with Gen11 graphics, will be called Lake Ice.

Willow Cove seems to be designing the core in 2020, probably also on 10nm. Intel lists the highlights here as a redesign of the cache (which may be L1 / L2 adjustments), new transistor optimizations (production-based) and other security features, probably referring to further improvements from new class of side attacks.

Round round cove out the triad, and is strongly in that section 2021 on the chart. The process node here is a question mark, but we are expected to see it at 10nm and 7nm. Golden Cove is where Intel adds another slice of serious cake to its plate, with increased performance in individual threads, focusing on AI performance, and potential networks and AI additions to core design. Security features also seem like they are getting a boost.

The lower roadmap of an atom microarchitecture is at a slower rate than the basic microarchitecture, which is not surprising considering its history. Since we see how an atom should fit a variety of instruments, we expect a wide range of capabilities, especially from the SoC.

Tremont's first microarchitecture for 2019 is focused on single-threaded performance growth, increasing battery life and network server performance. Based on some of the later designs in this article, we think it will be a 10nm design.

Following the Tremont will be Gracemont, which Intel lists as a 2021. As Atom is designed to continually push both the high-end performance of its capabilities and low-end efficiency, Intel lists that Gracemont will perform one more string to focus on increased frequency. This will be combined with additional vector performance, which is likely to Atom will get some wider vector units or support for new vector guidelines.

This transition will be a "Monte" core in the future (not a month as shown in the picture). Here Intel is spitballing what this new 2023 core may be, which is a general list of performance, frequency and features to have.

As stated, these are just microarchitecture names. The actual chips in these cores will probably have different names, namely Lake Name for the microarchitecture core. At the event, Intel declared that Cooper Lake would be the core of this Sunny Cove, for example.

Another aspect of Intel's presentations was that future microarchitectures are likely to be uncoupled from all process technologies. In order to build some flexibility into the company's product line and move forward, both Raja Koduri and Dr. Murthy Renduchintala explained that future microarchitectures will not depend on the process, and the newest products will reach the market for the best technology and process available at the time. Some core designs foster various production technologies.

Intel also went into detail about Sonny Cobb's microarchitecture.
