Explanation: The interaction between the latest 12th generation Core processor and memoryd by masters from these 4 dimensions!

On October 28, 2021, Beijing time, Intel officially released the 12th generation of Core processor, which again won the title of "the world's top game processor". It was the 10th generation of Core processor that last used this title, and the results of the game performance competition between the 10th generation of Core processor and the Reelon 3000 must be well known to everyone. Can Intel keep its promise this time?

The 12th generation core processors are i9 12900K (F), i7 12700K (F), and i5 12600K (F), all of which use intel 7 (10nm Enhanced Super Fin) technology and are equipped with UHD770 core display. The basic power consumption of the processors is 125W. i9 12900K uses 8 performance cores +8 energy efficiency cores, 16 cores and 24 threads. The maximum performance core core is 5.2GHz, the full core core is 4.9GHz, and the three-level cache is 30MB. The initial retail price is 4999 yuan. i7 12700K uses 8 performance cores and 4 energy efficiency cores. Based on i9, a group of energy efficiency cores are shielded. There are 12 cores and 20 threads. i5 12600K uses 6 performance cores and 4 energy efficiency cores. Based on i7, it shields 2 performance cores, 10 cores and 16 threads. The maximum core core is 4.9GHz, the maximum core core is 4.5GHz and the maximum core core is 4.5ghz, and the third-level cache is 20MB.

There are three points in the memory interaction section:

1. Compatible with DDR4 and DDR5

2. First XMP3.0 (add Gear 4 mode to the frequency division mode of the memory controller)

3. Dynamic memory frequency technology

The PCI-E channels integrated in the 12th generation processor are 16 5.0 (direct connection and independent display) and 4 4.0 (direct connection and M.2). The memory controller supports both DDR4 and DDR5. The frequency of the DDR5 supported by JEDEC standard is 4800MHz. According to the actual situation, It is easy for XMP or overclocking to exceed 5000MHz or even 5500MHz (the Z690 motherboard on the market will have DDR4 slots and DDR5 slots, so players who buy it need to look carefully to avoid buying DDR5 memory). In the 11th generation Core Rocket Lake architecture, Intel introduced the frequency division mode of the memory controller: Gear1 and Gear2 modes. The 12th generation Core Alder Lake-S also adopts the same design, and the Gear 4 mode is added to prepare for the future high-frequency DDR5 memory. The Gear 1 mode basically corresponds to the DDR4 3200MHz - 3600MHz gear, the Gear 2 corresponds to the DDR5-4800MHz - 7200MHz, and the Gear 4 corresponds to the frequency above 7200MHz. The Gear 4 will not be useful in a short time. Basically, DDR4 players use Gear 1 and DDR5 players use Gear 2.

The memory related XMP technology has also evolved to the XMP 3.0 specification. Many people may not know that XMP technology is actually a patented technology of Intel. Many AMD platforms, such as D.O.C.P, will be renamed. XMP's memory will also be written "compatible" with AMD platforms to avoid patents.

XMP 3.0 supports 3 manufacturers' configurations and 2 players' customized configurations, and supports the naming of XMP archives by players. What do you mean? Generally, when XMP is enabled, some high-frequency memories have two frequency configurations, such as 4800MHz for the first gear and 4400MHz for the first gear. XMP 3.0 can support three configurations. The player customized configuration is similar to the screenshot of the pirate ship. You can drive the XMP settings of the customized memory to facilitate the player to save the settings into the memory after overclocking, and no longer need to brush the SPD.

For memory overclocking, Intel also introduced the "Dynamic Memory Frequency Technology" on the 12th generation Core, which can be understood as the energy saving state of memory. When there is load, the memory frequency is increased to the set value, and when there is no load, the memory automatically reduces the frequency and voltage to the default state, so as to reduce heat generation and power consumption.

On the whole, the processing capacity of the memory applications of the 12th generation has been improved to a higher level. The upward breakthrough is not compatible with downward, so that other supporting hardware manufacturers have a transition period to break in. Consumers can also have more choices (DDR4 DDR5) to experience the latest things.
