Intel announced "12th generation Core processor (Alder Lake)" for high -end desktops from November 4 (page 1/2)

　Intel announced on October 28 (US Pacific Time) a CPU for high -end desktop PCs, the 12th Core Processor.The estimated selling price of the CPU single package in the United States is $ 264 to $ 589 (about 67,200 yen), and sales will start on November 4 in more than 30 areas including Japan.。PCs equipped with the CPU will also be released sequentially by the OEM partner.

　The 12th generation Core processor for general desktop PCs and laptops will be announced again in early 2022.

[Update: 13:30] Updated explanation about the standard of power consumption [Updated: 19:00] The release date notation has been partially changed.Along with that, the article title has been partially changed.

Outline of the 12th generation Core processor

　The 12th generation Core processor is a new CPU that has been developed under the development code name "Alder Lake".The design that combines the efficiency core (e core) is adopted.It also emphasizes scalability (flexible expandability), and is also characterized by a single architecture that can cover from a thin / small notebook PC (Ultra Mobile) to the desktop PC.

L2／L3キャッシュの実装変更

　The 12th generation Core processor has changed the design around the CPU cache memory.

　The L2 cache is MLC memory.P core has 1 core one by one.Equipped with 25MB independent L2 cache.On the other hand, e -core shares 4 core L2 cache.Therefore, if you have a product with a configuration of "P core x 8 + e core x 8", you will have an L2 cache with a total of 14MB (P core 10MB + E core 4MB).

　The L3 cache is TLC memory, which is "Intel Smart Cache" shared by Pc, E -Core, and GPU core.The capacity varies depending on the product, and the product announced this time is 20MB to 30MB.The CPU core and the GPU core access to the same cache memory has been reduced to suppress latency (delay) and improved overall performance.

　In the product announced this time, the PCI Express 5 directly connected to the CPU.0 Up to 16 lanes for buses, PCI Express 4.Up to 4 lanes for 0 buses can be used.PCI Express 5.0 Buses are external GPUs, high -speed storage (SSDs, etc.), PCI Express 4.0 buses are assumed to be used in high -speed storage.

　The main memory supports DDR5 and DDR4 standards ( * 1).The number of channels is up to two and the capacity is up to 128GB.However, be aware that the standards and number (capacity) of the memory that can be actually installed will vary depending on the chipset or motherboard to be combined.

( *) The maximum communication speed of the memory is 4800mt/s (DDR5-4800) for the DDR5 standard, and 3200mt/s (DDR4-3200) in the DDR4 standard.

All new CPUs this time compatible

　As mentioned at the beginning, all the new CPUs announced this time are products for high -end desktop PCs (SKU).Specifically, it is assumed to be used in gaming PCs and creators' PCs, and also supports "unlock".If you use it in combination with the simultaneously announced "Intel Z690 Chipset" (more detailed, described later), you can enable all overclocking functions.

　Of the new unlock elements, the focus is on "Intel Dynamic Memory Boost Technology".This is a technology that drives overclocking only when the DDR4 / DDR5 memory is needed in an environment that meets certain conditions.There is an advantage that can improve the performance around memory while reducing power consumption.

　The new CPU has two models, the top "Core i9", the top "Core i7", and the middle "Core i5", each with "built -in GPU" and "internal GPU (no F processor)".。The model with the built-in GPU is integrated with the XE-LP architecture-based GPU "Intel UHD GRAPHICS 770".

Core i9プロセッサ

　The Core i9 processor is available in "Core i9-12900K" with built-in GPU and "Core i9-12900KF" without built-in GPU.P core is "Intel Turboboost Max Technology 3.0 (TBT 3.0).The specifications are as follows.

Core i7プロセッサ

　The Core i7 processor has a "Core i7-12700K" with a built-in GPU and "Core i7-12700KF" without built-in GPU.P core is TBT 3.It corresponds to 0.The specifications are as follows.

Core i5プロセッサ

　The Core i5 processor has a "Core i5-12600K" with a built-in GPU and "Core i5-12600KF" without built-in GPU.The specifications are as follows.

Intel 600 Series Chipset also appeared sequentially

　Intel will release the "Intel 600 Series" as a chipset for the 12th generation Core processor for desktop PCs.The main features of the high -end "Intel Z690 Chipset" announced this time are as follows.

( * 2) In many areas including Japan, the configuration of the USB port varies depending on the motherboard for the 6GHz band due to laws and regulations ( * 3)
