ASCII.jp Cinebench recaptures the strongest seat!Core i9-12900K, Core i7-12700K, Core i5-12600K Bulletin Review

At 22:00 on November 4, 2021, Intel sold the sales of CPUs for desktop PCs, "12th Generation Intel Core Processor" (Developed Code: ALDER LAKE-S).The domestic selling price has been revealed one week before the ban.

The products announced this time are six types of models, including the "Core i9-12900K", "Core i7-12700K", and "Core i5-12600K", and the model of the built-in GPU with the end of the model number is "KF".The top Core i9-12900K costs less than 80,000 yen, giving a slightly cheaper impression than the competing AMD Ryzen 5000 series.

The 12th Generation Intel Core processor (hereinafter referred to as the 12th generation Core) is the first desktop PC main stream CPU that adopts "Intel 7" (once called 10nm Enhanced Superfin) as a process rule.From the 5th generation Intel Core Core processor (development code name: Broadwell-C), this person has been improving and using 14nm with such a hand, but has finally shifted to the new process in the 12th generation Core.

In the meantime, rival AMD evolves from 14nm to 12nm → 7nm (although the TSMC that has achieved this is also amazing), and even seems to enter 5 nm next year.Although there is a premise that this number should not be compared simply, it is attracting attention how Intel, which has stumbled once in the evolution of process rules, will return in intel 7.

In addition, the major topic is that the 12th generation Core is the first CPU of the "BIG.LITTLE" design, which is the first CPU for the mainstream with two types of core (P core and E core) with different properties.If you increase the core, the multi -thread performance will increase, but the power consumption will increase.This is an approach to enhance parallelity and power efficiency by combining low-clock but small power consumption E-core (Efficient-Cores) and high-performance P core (Performance-Cores).The aim is to enhance the responsiveness of moving multiple apps in parallel and enhance comprehensive output.

The use of this P core/e core is automatically performed by the OS, but the function "Intel Thread Director" (hereinafter, ITD) is included in the CPU.ITD also works on Windows 10, but says that it works most efficiently in combination with Windows 11.

Will it exceeded 5950X?!? Verify with 3 models of the 12th generation

Fortunately, I was blessed with the opportunity to test all three types of SKUs, Core i9-12900K, Core i7-12700K, and Core i5-12600K, in the Motherboard equipped with Intel Z690 chipset, DDR5 memory environment.

If you refuse from the beginning, the 12th generation Core is a very difficult CPU.There are many first elements (new architecture/new chipset/new memory standard), and the BIOS is still rough.Above all, there are many elements to verify, and time is severe.Therefore, we will explain and verify the characteristics of the 12th generation Core from various aspects from this time, but for a while, we will refuse to talk in "Windows 10" environment.By the way, if you want to know only the results of the benchmark because the classroom is long this time, you should fly here.

Core i9-12900K obtained this time.The marker shows the direction of the Golden Finger (golden triangle in the lower left corner of the CPU board) is engraved on the heat spread.

Front of Core i5-12600K

LGA1700 compatible CPU (left) and LGA1200 compatible CPU (right) have different physical shapes.Alder Lake-S (LGA1700-compatible CPU) is vertical, and the slaps are different.

As you can see from the capacitor placement on the back, the 12th generation Core dies are more vertical than the previous generation.LGA1700 compatible CPUs seem to have some lands connected, but they do not seem to be conducted within the tester.

Necessary points to understand the 12th generation Core

The specifications of the 12th generation Core have been revealed in the Intel Innovation article held the other day, but let me explain again.

The 12th generation Core has a P -core composed of "Golden Cove", which has enhanced Tiger Lake architecture, and a hybrid composition based on Atom (Gracemont).P core is designed to emphasize single -threaded performance and low latency, but has a large power consumption, E -core is a low -clock and low power consumption, but is designed to emphasize the simultaneous execution capacity (execution port) of instructions.

The operating clock is the top core i9-12900K, up to 5.2GHz, and has the number of core (e core).I would like to pay attention to the fact that the higher the model, the lower the base clock, and the higher the number of cores, the higher the base clock.

The specifications comparison of the 11/12 generation Core.All previous generation core is treated as P core

I picked up the information of Core i9-12900K with "CPU-Z".The number of physical cores in the lower right is "8+8", which is notation that is conscious of the difference in the type of core, while the logical core (Thread) is not distinguished from "24".
