The purpose of this work is to improve the performance and efficiency of Intel’s 12th Generation “Alder Lake” and 13th Generation “Raptor Lake” processors. Given that previous proposals around the introduction of IPC classes for load balancing did not receive any strong opposition, the project removed the Request for Comments (RFC) tag, and the next phase aims to be integrated into the Linux Mainline kernel.

On hybrid processors, the microarchitectural properties of different types of CPUs cause them to have different instruction-per-cycle (IPC) capabilities. On some CPUs, the IPC priority of advanced instructions can be higher. A load balancer can discover whether advanced instructions are used and give preference to CPUs with higher IPC for tasks running those instructions.

Hardware is free to divide its instruction set into any number of categories. But there must be a mechanism to identify the class of tasks currently running and tell the kernel how each class of task will perform on each class of CPU.

The patch set released by Intel on Monday introduced the concept of task categories, clarified the interfaces required for hardware implementation, modified the load balancer, and used asymmetric packaging to better utilize this additional information to achieve enhanced performance. Purpose.

Since the release of the original patch, some code improvements have been made based on code review and testing. The CONFIG_SCHED_TASK_CLASSES option was renamed to CONFIG_IPC_CLASSES. This patch series also drops the CONFIG_INTEL_THREAD_DIRECTOR knob. But the rest of the changes are mostly low-level changes.

Intel’s Alder Lake-N processors are based on the energy-efficient Gracemont architecture, with up to 8 cores divided into two quad-core clusters. This series of processors also have Xe-LP architecture with core graphics up to 32EU.

A few days ago, a 4-core Alder Lake-N appeared in the database with the model number N100.

Sources say Intel’s Alder Lake-N processors will be used in NAS, mini-hosts, and embedded platforms.

For now, Intel has not officially announced the Alder Lake-N series of processors.

GPD WIN Max 2 Key Features.

● 10.1-inch bezel-less, blue light filtering eye protection screen

6061 aluminum-magnesium alloy / all-metal CNC body

● Optional Intel Core i7-1260P or AMD Rex R7-6800U processor

● Iris Xe with 96EU / Radeon 680M with 12CU core graphics (both with 768 shaders) respectively

● Optional 16/32GB of LPDDR5 memory (5200 or 6400 MT/s format)

● Dual PCIe 4.0 M.2 slots (optional 2280 or 2230 SSD form factor)

● Bluetooth 5.2 + Wi-Fi 6 wireless network support up to 2402 Mbps

It also comes with a large scroll fan dual heatpipe cooler, a fingerprint sensor and 4G LTE mobile internet module, built-in quad speakers with surround sound support, and Windows 11 Home Edition pre-installed.

The analog joystick uses an anti-drift Hall sensor solution and is complemented by a QWERTY keyboard with two levels of adjustable backlighting and an external graphics card docking station via Thunderbolt 4.

The GPD WIN Max 2 measures 160 x 227 mm, but is slightly thinner than the 117 x 298 mm Steam Deck.

It has a 90% screen-to-body ratio, 1920×1200 resolution (2560×1600 optional), 299 PPI pixel density, 400 nits brightness, and covers 80.2% DCI-P3 color gamut.

With the optional AMD R7-6800U low-voltage mobile processor, it has a maximum acceleration of 4.7 GHz, a large 67Wh built-in battery, and support for 100W PD fast charging.

An SD / microSD card reader is available, as well as HDMI 2.1 video output, four USB 3.2 Gen 2 ports, and a 3.5mm headphone/microphone combo jack.

Clearly, after 5~6 years of experience, GPD has become more mature in hardware design. Not only is the form factor suitable for mobile gaming and office use, but the grip also claims to be better than competing products.
