With Intel releasing Comet Lake-S, their competition with AMD in the CPU market is in full reach. Now, neither of them has yet to clearly announce the next steps, but it is already necessary to sort out the CPU roadmap for the two companies from this year to the next year, the year 2022. This article is based on a variety of messages, leaks summarized.
Intel side: Rocket Lake and Tiger Lake will hold out next year
Intel’s side is currently at a significant competitive disadvantage due to the process, but big-business Intel will follow the original roadmap update. The next-generation architecture currently publicised is the mobile Tiger Lake.
Tiger Lake is the optimization step of Intel’s three-step strategy of process-architecture-optimization (PAO), in which Intel actually completed the process upgrade, opening up its own 10nm era, and also completing the decoupling of the kernel microarchitecture and the CPU overall architecture, the kernel microarchitecture code is no longer the same as the CPU architecture code, but with its own specific name, such as Ice Lake using the name Sunny Lake Cove’s kernel microarchitecture. Tiger Lake will use the Next Generation of Sunny Cove, the Willow Cove kernel.
At Intel’s 2018 Architecture Day event, they unveiled a roadmap for kernel microarchitecture for the next few years, and you can see that Willow Cove has three major changes compared to Sunny Cove: cache re-design, new transistor optimization, and security features. The first point we’ve seen in the identification of various test software shows that Tiger Lake’s L2 and L3 are significantly larger, with the single-core L2 cache amplified from 512KB to 1.25MB, and the L3 growing to 3MB per core.
On the desktop side, Intel plans to launch a generation of Rocket Lake, which still uses a 14nm process, to upgrade the kernel microarchitecture, Intel desktop processor’s long-stalled IPC is finally on the rise, but there are now two ways to say about the kernel microarchitecture that Rocket Lake specifically uses, one saying it uses Sunny Cove and the other saying it uses Willow, and it’s good to have a boost anyway. Based on the current leak situation, the Rocket Lake-S power consumption level will still be at a fairly high level, after all, whether it is Sunny Cove or Willow Cove, its core is more than one size, and because a single core occupies a larger area, in order to ensure production and yield, the desktop-level Rocket Lake-S will limit the maximum number of cores per processor to eight.
Tiger Lake will be officially released later this year, and we expect to see a lot of new notebooks using the Tiger Lake platform by the end of the year. Rocket Lake-S, unsurprisingly, will make his debut in the second quarter of next year to replace the current Comet Lake-S.
And then… Alder Lake will appear, and legend has it that it will use a configuration of an 8-plus-8 combination of nuclei, a large core using Willow Cove’s next generation, a kernel microarchitecture code-named Golden Cove, and a small core that will use Tremont’s next generation, code-named Gracemont’s microarchitecture. It will put something similar to big. LITTLE’s idea is a high-performance x86 platform, and its process should be replaced with 10nm.
Later, a generation of Meteor Lake has appeared in Intel’s current drive files and is believed to be using the 7nm process.
AMD Party: Zen 3 and various APUs
AMD’s new products are still pretty clear, and their next product to be released next should be Matisse Refresh, a frequency upgrade of several currently-popular Zen 2 processors, which are believed to have the XT model suffix. Then there’s the desktop version of the Renoir processor, which may appear with Matisse Refresh, or at some point later.
The above two series do not exist in AMD’s official public information, the public information only Zen 3 architecture and next-generation processor schedule, you can see this year AMD will launch a new generation of Zen 3-based processor, code-named Vermeer, now from various sources can learn that Zen 3 single-threadperformance will be double-digit level improvement, which means that it is not just to change the CCX structure so simple, the kernel microarchitecture will also have a larger upgrade.
Then there’s AMD’s layout in the mobile market. A recent consolidated table for AMD’s future processor roadmap let’s take a look:
What is more useful to us in this table is the layout on MSDT and APU next year, and you can see that amd slays next year are an APU called Cezanne, followed by a new APU code-named Rembrandt, but the table doesn’t mark exactly what kind of architecture they will use, but we have the latest news from anonymous informants.
Cezanne will use a combination of Zen 3 plus Vega 7 instead of the rumored RDNA 2, which will continue to use TSMC N7, which, like Renoir, will have both low pressure and voltage. Rembrandt is a very large update, the CPU architecture will use Zen 3 plus, and the GPU is finally out of the Vega architecture, in exchange for RDNA 2, in terms of process, it will be updated to TSMC’s 6nm, that is, N7 optimization process, and will support DDR5, LPDDR5, in addition, USB4 and PCIe 4.0 two new buses will also be available on this generation of architecture.
AMD also plans a processor called Van Gogh at ultra-low voltage, which is like a lithograph of the PS5, Xbox Series X custom processor, and also features the Zen 2-RDNA 2 architecture, but tDP is limited to 9W for lightweight mobile devices.
If you use a roadmap to simply represent AMD’s layout on the desktop CPU and APU, that’s true, but there’s no guarantee that the point in time will be right.
Summary: CPU market changes
In the next two years of the CPU market, without surprise, Intel will go through a period of relatively weak, by the process seriously dragged down by their late decision to put the new core on the desktop processor, so that their own desktop processor in the same frequency has begun not to dominate, how much Rocket Lake-S can recover is still unknown, and in the mobile market, Tiger Lake and optimized 10nm plus process can not make energy consumption than a bit more than a bit of mystery. Amd’s implementation of the roadmap is still relatively good, the end of this year we should see the Zen 3 processor, and with Renoir’s successful paving, next year’s mobile market, there will be more manufacturers choose to use APU.
