Intel soul torture: 14nm is not good?

AMD recently advertised its own Radon processor, and proposed five reasons to fall in love with the Ruilong 3000 processor, one of which is the 7nm process, which is indeed the most advanced of the current X86 processors, compared to Intel's The desktop processor also stays at the 14nm node.

Is 7nm vs. 14nm an advantage? This problem is of interest to the manufacturer because more advanced processes can produce processors with higher performance, lower power consumption, and smaller area, but for the reader, the entanglement process is of little significance, because no matter what process, What consumers see is actually performance, power consumption, heat, price, etc. These factors are not necessarily linked to the process.

Intel senior engineer Ophir Edlis also talked about similar views in an interview. Forbes asked Intel when it will launch a 10nm desktop processor, because the current 10th generation Ice Lake is only mobile.

About this question,Ophir Edlis first said that there was no comment and could not answer information about new products that had not been released yet. However, he asked everyone why they should pay attention to whether it is a 10nm process. Is the 10nm process necessary for the processor?

Ophir Edlis emphasizes that the process is just one part of the processor. Just like a knob, Intel has many tools (knobs) to use.

In the current situation, it is not surprising that Intel does not emphasize the advanced process technology. After all, their progress is really outdated in this respect. When Intel’s technology was leading in the past few years, Intel’s advantages in advanced technology were The book is special.

It's not just Forbes' attention. In fact, after the announcement of the Intel 10nm process, everyone is paying attention to the 10nm desktop processor, because the 14nm process is a bit tired now, and the process has not been upgraded. Intel has been changing the Skylake architecture, Sunny Lake of Ice Lake. The core is matched with the 10nm process, and it is impossible to see the new architecture without giving the 10nm process on the desktop.

On the other hand, Intel's support for 10nm processors is also difficult to say, because the 10nm desktop processor is likely to wait a long time. From the previously leaked roadmap, there will be at least the CometLake comet generation in the 14nm node. The DIY player support will still be 14nm in 2021.

As for whether the desktop processor will skip the 10nm generation directly, this is not impossible, because Intel will mass produce the 7nm process in 2021. Although the Xe architecture GPU is the first one, how to use it for the CPU in 2022? There are not many opportunities left for the 10nm desktop processor at this point in time.


In fact, at the Taipei Computer Show at the end of May this year, Intel officially released the Ice Lake series of 10 generations of Core Duo processors, including the Core i7, Core i5, Core i3 and Iris Plus core graphics cards, all of which have been replaced with new ones. The LOGO logo, but the 10th generation Core is mainly for notebooks.

According to Intel's statement at the earnings conference, the 10th generation Core processor has already been shipped to OEM/ODM vendors, and notebooks, tablets and other terminal products equipped with next-generation processors are expected to be available this Christmas shopping season.


At present, Intel has two fabs to produce 10nm processors, and in 2021, it will launch 7nm process, which is known as the 5nm process of the company.

The ten generations of Core Code, Ice Lake, in addition to upgrading to the 10nm process, also used the new SunnyCove core architecture and Gen11 core display, which can be said from CPU to GPU, from memory to multimedia, from display output to image processing, from each other Even the bus to the Thunderbolt 3 is new.

As for performance, according to Intel's previously published data, the SunnyCove architecture has increased IPC performance by up to 40% compared to the previous Skylake architecture, with an average increase of 18%.

The Ice Lake processor is the first in the mobile segment to be divided into low-power Ice Lake-U and ultra-low-power Ice Lake-Y sub-series. The thermal design power is 9W, 15W, 28W, and up to four cores. Thread, the maximum acceleration frequency is 4.1GHz (reduced), the maximum level 3 cache is 8MB, the integrated core is divided into Iris Plus (48/64 unit), UHD (32 unit), maximum acceleration frequency 1.1GHz, memory support double Channel DDR4-3200 (U series), LPDDR4/4X-3733.


How to develop next? I am afraid that the chipset from the end of this year to next year will be more chaotic than before, because this time it will cross the 14nm/10nm process processor, involving mobile and desktop platforms.

On the mobile platform,Intel announced the ten-generation Core processor at the Taipei Computer Show in late May, which is the 10nm Ice Lake processor. The chipset they paired with is the 495 series.However, the notebook processor has nothing to do with the desktop platform, and the 495 chipset DIY players are not in contact.

Related to DIY players is the Comet Lake Xing Xing Lake processor, which should be a desktop-class 10th generation Core processor (same generation, the desktop and mobile version of the first process is completely different).

According to previous reports, the number of CPU cores in the Xingxing Lake has increased to 10 cores based on the existing 8 cores. The CPU acceleration frequency has increased by about 200 MHz, and the memory frequency has increased to DDR4-3200. The price remains unchanged.


The increase in the number of cores of the Xingxing Lake processor is a good thing. After all, this is the biggest temptation for the player in the case of the same structure and craftsmanship, butThe chipset of this generation of processors will also be upgraded, from the current 300 series to the 400 series, the specifications are not certain.

The bad news is that the slot of the 400 series motherboard has to be returned. The previous report shows that the LGA1159 is more than 8 pins than the current LGA1151. However, there are other sources that the new slot is the LGA1200, and the number of pins is more. It is.

Regardless of the pin, the LGA slot of the 14nm Iridium Lake processor is not compatible with existing products and should not be running.

10 When the release of the Nuclear Star Lake and the 400 Series motherboards is uncertain, Intel's fall convention will have a press conference. This is the time to release the 10th generation Core Desktop processor this year, otherwise it will wait until early next year.

From the latest trends, motherboard manufacturers have begun to prepare for the 400 series motherboards, but now in the NDA, the details broke.
