Intel said Al is being integrated into every aspect of people’s lives. Although cloud AI provides scalable computing, there are limitations. It is characterized by dependence on connections, high latency, high implementation costs, and privacy issues. MeteorLake brings AI to client PCs, providing low-latency AI calculations that better protect data privacy at lower costs.

Intel said that starting with MeteorLake, Intel will widely introduce Al to PCs, leading hundreds of millions of PCs into the Al era, and the huge x86 ecosystem will provide a wide range of software models and tools.

A detailed explanation of Intel NPU architecture:

Host Interface and Device Management – The Device Management area supports Microsoft’s new driver model called the Microsoft Computing Driver Model (MCDM). This enables Meteor Lake’s NPUs to support MCDM in a superior manner while ensuring security, while the memory management unit (MMU) provides isolation in multiple scenarios and supports power and workload scheduling, enabling fast low-power states Convert.

Multi-engine architecture – The NPU consists of a multi-engine architecture with two neural computing engines that can work together to process a single workload or each to process different workloads. In the Neural Compute Engine, there are two main computing components. One is the inference pipeline – this is the core driver of energy-efficient computing and handles common large calculations by minimizing data movement and leveraging fixed-function operations. Tasks can achieve energy efficiency in neural network execution. The vast majority of computation occurs in the inference pipeline, a fixed-function pipeline hardware that supports standard neural network operations. The pipeline consists of a multiply-accumulate operation (MAC) array, an activation function block, and a data conversion block. The second is SHAVEDSP – a highly optimized VLIW DSP (Very Long Instruction Word/Digital Signal Processor) designed specifically for Al. The Streaming Hybrid Architecture Vector Engine (SHAVE) can be pipelined with inference pipelines and direct memory access (DMA) engines to enable truly heterogeneous computing in parallel on the NPU to maximize performance.

DMA Engine – This engine optimally orchestrates data movement for maximum energy efficiency and performance.

A presentation titled “Meteor Lake Preliminary Mobile SKU Lineup” was shared in the video, detailing the MTL-U, MTL-P, and MTL-H processors, and mentioning the 55W PL1 power-constrained Raptor Lake Refresh (RPL) processor.

The summary information is as follows:

Intel Meteor Lake-U

The low-end MTL-U SKUs are limited by the 7W PL1 TDP and range from a 5-core Core i3 to a 9-core Core i7:

Core i3 processor

It includes 5 cores, 1 P core and 4 E cores, and 3 Xe integrated graphics cores.

Up to Core i7 processor

It includes 9 cores, 1 P core and 8 E cores, and 4 Xe integrated graphics cores.

The high-end MTL-U processor has a 15W PL1 TDP limit, and you can choose up to a 12-core Core i7, equipped with 4 P cores + 8 E cores, and 7 or 8 Xe integrated graphics cores.

Intel Meteor Lake-P

Next, introduce the 28W MTL-P. The slide shows that the Core i5 model can be equipped with up to 10 cores (2 P cores + 8 E cores), with 4/7 Xe integrated graphics cores; the Core i7 can be equipped with up to 14 cores. Core (6 P cores + 8 E cores), with 8 Xe integrated graphics cores.

Meteor Lake-H

Meteor Lake-H includes a 12-core Core i5, a 14-core Core i7, and a 14-core Core i9, all with eight Xe integrated graphics cores and a PL1 power limit of 45W.

In addition to the MTL lineup, MLID also leaked a slide that mentions that MTL’s Xe LPG iGPU has a 33% increase in graphics cores over the Iris Xe in the Raptor Lake chip.

The Iris Xe graphics inside the Intel Raptor Lake mobile processor is equipped with up to 96 execution units (EU), and MTL’s Xe LPG iGPU can pack up to 128 EU, an increase of 33%.

The post Intel Meteor Lake mobile lineup exposed with Core i9 up to 14 cores appeared first on TechGoing.

Instead of a monolithic design, the Meteor Lake processor uses a decentralized design, combining chiplets to meet different tasks.

The main technology for the versatile processing unit (VPU) available in Meteor Lake comes from Movidius, a company Intel acquired in 2016. By introducing VPU, Intel can accelerate tasks related to AI algorithms and machine learning models.

The main tasks of the VPU in Meteor Lake include real-time processing of photos and videos, filtering applications, auto-blurring backgrounds, scaling applications, replacing images, and more, in addition to the VPU’s ability to recognize user eye movements and gestures in real time.

The processor was completed two weeks ago and features 16 cores with 22 threads, 1.6 MB of L1 cache, 18 MB of L2 cache, and 24 MB of L3 cache.

The post Intel Group demonstrated Meteor Lake processor, real-time processing of photos, videos appeared first on TechGoing.

According to data seen by Wccftech, the processor was completed two weeks ago and has 16 cores and 22 threads. Referring to previous leaks, this is probably the 6 P +8 E + 2 E (SoC) configuration we’ve seen before.

As you can see below, it has 16 MB of L1 cache, 18 MB of L2 cache and 24 MB of L3 cache. Due to the initial Intel 4 process, the current Meteor Lake processors seem to be underclocked with a base frequency of 3.1 GHz, and this ES processor even has an idle frequency of 0.37 GHz.

As you can see from the picture, Intel also equipped it with a new VPU. interestingly, Windows detects it as Movidius.

Intel says that the chip on the Meteor Lake SoC is three generations ahead of Movidius, but has the same IP (which is why Task Manager detects it as a Movidius NPU). Also, we can see that the VPU will use about 1 GB of shared vRAM memory to do its job.

briefly compiled a reference to the specifications of the current quad-generation processors, but there is still some information that cannot yet be verified:
CPU Arrow Lake Meteor Lake Raptor Lake

The post Intel shows Meteor Lake prototype: 16 cores, 22 threads, L1+L2+L3 cache 58M appeared first on TechGoing.

The video information says that the Intel Meteor Lake desktop processor (MTL-S) supports up to 14-core Core i5, including 6 performance cores and 8 efficiency cores. The Arrow Lake architecture will launch Core i7 and Core i9 SKUs.

Paul said the MTL-S entered the ES1 (engineering sample) stage last month, while the mobile MTL-P entered the ES2 stage in March 2023.

Paul said that the top-of-the-line Core i9 based on the Arrow Lake architecture will contain 8 Lion Cove P cores and 16 Skymont E cores.

Paul said that compared with Raptor Lake, the IPC improvement of the Arrow Lake architecture is about 18%-20%. This is roughly in line with the IPC lift figures reported by MLID in March (22-34%), and with Paul’s leaked data from February 2023 onwards.

Intel’s latest Linux patch submission hints that Meteor Lake will support L4 cache, which is really rare in processors. “On MTL, GT can no longer be allocated on LLC — only the CPU can. This plus support for ADM / L4 cache together is called a MOCS / PAT table update.”

Of course, we’re not sure what the “ADM” in the patch stands for yet, and the code doesn’t expose the size of the ADM. We think it may just be a marketing term for L4 cache.

In retrospect, Intel has included 128MB of eDRAM for the initial 14nm Broadwell (i7-5775C and i5-5765C, essentially the 14nm version of Haswell), which can be used as the L4 cache for the CPU. In addition, some of Intel’s Coffee Lake-U processors also have 128MB of eDRAM cache.

Of course, Intel has only adopted this design in a few of its chips for NUCs, as the L4 cache is slow, so it is difficult to get a system performance boost other than with integrated graphics.

During the Hot Chips 34 demo, Intel shared the schematic of Meteor Lake, which will use Intel 4 process and external process and introduce the first “Tile” design with four different parts: CPU, SOC, graphics and IOE.

So, the base part of Meteor Lake may contain L4 cache, like Ponte Vecchio’s 144MB L2 cache, but we’re not sure where it will be placed yet, but Intel seems to have planned to prohibit Meteor Lake’s iGPU from accessing the LLC (Last Level Cache), only the CPU part can, so it’s definitely not the graphics part. not the graphics part.

In short, the design is similar to AMD’s Ryzen APU, whose CPU core and iGPU cache are not shared, which means its core graphics will be more dependent on high-frequency dual-channel memory.

According to SquashBionic, the MTL-S supports DDR5-6400 memory, but it depends on the exact configuration of the die. He says: the current engineering sample MTL-S (6+8) supports 5600 MT/s, while MTL-S (6+16) supports 6400 MT/s.

In addition, according to @9550pro, it seems that Intel’s new Meteor Lake series can only be used on low-voltage platforms, at least this year’s new desktop processors and the HX series processors for mobile platforms are still the Refresh versions of the 13th generation Core Raptor Lake, and only next year will new motherboard + new architecture CPU products appear. Of course, both are called 14th generation Core.

In terms of process, Intel announced that Intel 7 process has been mass-produced, Intel 4 production is ready, and with the launch of Meteor Lake, Intel 4 production capacity will be enhanced in the second half of this year. In addition, the Intel 3 process is progressing on schedule, and test chips for the Intel 20A and 18A processes are already flowing.

The post Linux patch hints at L4 cache for Intel’s Meteor Lake processors appeared first on TechGoing.

According to the latest pictures released by the whistleblower momomo_us, the OpenVPL (Video Processing Library) hardware support list shows that Intel’s 14th-generation Core processors are listed as MTL / Meteor Lake.

That is to say, Intel’s 14th generation Core will not be a small facelift product of Raptor Lake Refresh, so the new Raptor Lake Refresh desktop product that will be launched in the third quarter of this year will have another name, and the possibility of a new 13th generation Core model is not ruled out. The end Meteor Lake processor will not be released anytime soon.

According to previous reports, Intel’s upcoming Meteor Lake mobile processor has appeared in the UserBenchmark database.

As shown in the figure above, this processor is still in the ES stage, with parameters of 4 P cores and 8 E cores, a total of 12 cores and 16 threads. The core display is recognized as the Arc series, which should be the latest Xe-LPG architecture, which has improved performance compared to the current Xe core display.

According to Intel, the new generation of processor Meteor Lake (expected to be mobile) will be launched in the second half of 2023. Meteor Lake will use the Intel 4 process and external process, and introduce the “Tile” design for the first time, integrating CPU, SOC, nuclear display and IOE chips.

Microsoft and Intel declined to comment on the post. In the summer of 2022, a new report says Microsoft has changed its plans to go back to releasing new Windows every three years, rather than continuously servicing one version (remember the “Windows 10 is the last Windows”) The last Windows 10. Although Microsoft has not yet confirmed Windows 12, it is already predicted to be the successor to Windows 11.

Microsoft is already trying to integrate AI into Windows 11. Although the first attempt was a bit lame, Microsoft is exploring different ideas to enhance its operating system with AI, as Microsoft’s consumer marketing chief explained in a recent interview with The Verge.

“As we begin to develop future versions of Windows, we will consider the natural role AI plays in their experience.”

Implementing AI-based features in Windows 12 means that Microsoft needs to strengthen its relationships with Intel, AMD and Qualcomm. So it’s not surprising to see the document mention the next operating system. AI-driven features typically require deeper integration with hardware, and the three PC processor makers are already working in that direction. For example, AMD’s recent Ryzen 7000 mobile chip has a dedicated AI engine for Microsoft Windows Studio Effects, including noise suppression, eye contact, background blur and more.

Intel’s Meteor Lake platform is expected to arrive in 2024, just before the third anniversary of Windows 11 and the big debut of Windows 12. However, there is no official confirmation yet. Moreover, Microsoft’s plans can be changed at any time, just as some products like the Surface Mini were canceled before their release.

According to the material shared by Intel before, the new generation of Meteor Lake will use Intel 4 process and external process, and for the first time introduce the “Tile” design, integrated CPU, SOC, core graphics and IOE chip, but Intel did not confirm whether Meteor Lake is suitable for desktop platforms.

In addition, Intel has introduced a general purpose processing unit (VPU) gas pedal for computer vision (CV) and deep learning (DL) work for the next generation of Meteor Lake processors.

Intel sent out a request last Tuesday, primarily for a drm-misc-next pull on DRM-Next ahead of the Linux 6.3 merge in February, the most important of which is the introduction of a kernel driver for the new Intel VPU accelerator.

In fact, Intel submitted the open-source driver code for the Intel VPU (not to be confused with the Visual Processing Unit or Video Processing Unit) to Linux as early as last summer.

The driver is also available for Linux’s new compute gas pedal “accel” framework/subsystem. The driver is now ready for Linux 6.3, when this “iVPU” will be the first driver in the accelerator subsystem.

In addition to the fully open source Intel VPU driver, Intel has also released its open-source user space VPU driver code. In addition, in order to facilitate developers to use Intel VPU, they also provide compiler and driver support in OpenVINO, so stay tuned.

According to material previously shared by Intel, the next generation of Meteor Lake will use Intel 4 process and external processes, and for the first time introduce a “Tile” design with integrated CPU, SOC, core graphics and IOE chips.

Intel has not confirmed whether Meteor Lake is available for desktop platforms. Rumors suggest that Intel’s next-generation desktop processors will be a Refresh version of the 13th generation Core Raptor Lake, with only the mobile side being upgraded to Meteor Lake.

Intel Lunar Lake is expected to be a 15W low-power mobile CPU with a redesigned architecture that focuses more on performance per watt for mobile devices.

On the process side, Intel announced that Intel 7 process is in mass production, Intel 4 production is ready, and Intel 4 capacity will increase in the second half of this year with the launch of Meteor Lake. Intel 3 process is progressing as planned, and Intel 20A and 18A process test chips are already flowing.
