If the biggest feature of the 11th generation Core processor is to enter the 10nm process, then the biggest feature of the 12th generation Core processor is the use of a new hybrid architecture, the performance core (Performance Core) and the energy efficiency core (Efficient Core) work together, through the hardware thread scheduler for management and allocation, while taking into account the single-thread high performance and multi-threaded full output performance.
Intel releases 12th generation Core mobile processors
The IPC of the 12th-generation Core mobile processor family has been greatly improved, while the L2 and L3 caches have been greatly increased, allowing it to take a qualitative leap in performance.

What is the Thunderbolt 4 interface?
Raiden 4 is an advanced data transmission standard, which is a new generation of high-speed interface standard promoted by Intel, which is iterated from the previous generation Of Lightning 3. In terms of interface, the physical form is exactly the same as USB-C, and it supports positive and negative blind insertion.
The maximum transmission rate of Raiden 4 is 40Gbps like Raiden 3, the difference is that Raiden 4 "patches and improves" some parts of Raiden 3, such as Raiden 4 interface requires support for connecting 4 lightning accessories, supporting 2 meters 40Gbps cables, light and thin notebooks mandatorily requiring at least one lightning interface to support input charging, supporting VT-d-based DMA protection to improve security, and so on.
First, let's introduce how big the rate gap is, the most common USB2.0 interface transfer rate is only 480Mbps, USB3.2 Gen1 is only 5Gbps, USB3.2 Gen2 is increased to 10Gbps, and USB3.2 Gen2x2 is only 20Gbps.
In terms of lightning, Raiden 4 and Raiden 3 both support the upper limit of 40Gbps data transmission rate, Raiden 3 reserves 18Gbps bandwidth for DP video, and the data transmission bandwidth is 22Gbps, while Raiden 4's DP video reserved bandwidth is 8Gbps, and the data transmission bandwidth is increased to 32Gbps, and Raiden 4 is faster when using high-speed peripherals.
In addition to video signaling and data transmission, Raiden 4 also supports power transmission. In terms of specifications, Raiden 4 supports up to 20V5A, that is, 100W upper limit, the protocol is compatible with USB PD fast charging standards, and the notebook can easily use the Raiden 4 interface to connect to the docking station, monitor, charger, mouse keyboard, U disk and other peripherals, enjoy all the convenient experiences of one-line pass.
Charging head net summary
Intel Lightning standard has been introduced for several years, although the rate of high performance is strong, but due to compatibility and support of the few devices, resulting in the price of accessories is extremely expensive, the lightning ecosystem has been difficult to develop and form. This time Intel 12th generation Core mobile processor, H45, P28, U15, U9 four series all native support Raiden 4, up to 4 Thunderbolt 4 interfaces, whether you use it or not all standard, for the Thunderbolt 4 interface of the large-scale rapid popularization of clear obstacles.
Raiden 4 interface is compatible with USB PD fast charging protocol, up to 100W PD fast charging, notebook space is limited, Thunderbolt interface integrates high-speed data, high-power charging, high-definition video transmission three functions, for the notebook valuable space to provide a perfect solution.
Raiden 4 has a 40Gbps rate bandwidth, supports ultra-high-definition video transmission, supports 100W PD power transmission, so that it can connect to the monitor, mouse keyboard, docking station, U disk and other peripherals on the desktop with only one cable, perfectly adapting to the use of notebook features. It is believed that in the future, after the full popularization of notebooks equipped with Thunderbolt 4 interface, the choice of high-speed accessories will become more and more abundant, and the price will be more affordable.
