Announcement of COFFEE LAKE-S, 6-core super enhancement Core i7 and HT disappeared in the 8th generation Core

　It is Jisa Treppii.Intel has finally announced the 8th generation Core processor (development code name: Coffee Lake-S) for desktop PCs.The company just announced the 7th generation Core processor (Kaby Lake-S) on January 4 this year.The reason for the launch of a new product in just less than 10 months is because of the competition.How is that performance?

COFFEE LAKE-S die.

　The COFFEE LAKE-S announced this time has a total of 6 models, led by the top model "Core i7-8700K".It is a so -called mainstream located in the middle of entry classes such as Celeron and Pentium and the high -end Core X series.The feature is that it has a magnification lock -free model for overclocking, which has up to 6 cores/12 threads with "K" at the end of the model, and PCI Express 3..The number of lanes in 0 is up to 40 lanes (including chipset).

The 8th generation Core processor for desktop PCs is the mainstream.This class is used for the most self -made PC/BTO machine.Since the material is launched on October 5th, is it expected to be shipped on October 5?

The Coffee Lake-S announced this time is a total of 6 models.

　The biggest feature is that it has increased by 2 cores compared to the 7th generation Core processor."Core i7-8700K" and "Core i7-8700" are 6 cores/12 threads, "Core i5-8600K" and "Core i5-8400" are 6 core/6 threads, "Core i3-8350K" and "Core i3"-8100 is 4 cores/4 threads.What I want to pay attention to here is the number of threads of "Core i3".Until the previous generation, Core i3 was 2 core/4 threads, but it can be seen that the physical cores have increased by two but the hyper -led (HT) is not compatible.

　Until now, Core i7 = maximum core with HT & turbo boost (TB), Core i5 = maximum core, no HT & TB, Core i3 = maximum core-2 core and no HT and TB.I3 = Maximum core-2 core must be changed with no HT & TB.

　So why did such rules change?I think it's probably in the price of Core i3.The Core i3-8350K announced this time is $ 168.The first price of the previous generation "Core i3-7350K" is $ 168, so you can see that the price is exactly the same.In this way, even if the number of cores increases, the price is difficult to move because it is a CPU of the same class.

　However, if it is released with HT like the successive Core i3, it will be a "4 -core/8 thread CPU" although there is no TB.The position of "4 core/8 thread CPU" has been a long -term privilege of Core i7, so if this is the case, the purchasing layer will overlap with the successive Core i7.

　In addition, the L3 cache of the previous generation Core i3-7350K was 4MB, but the Core i3-8350K this time has improved to 6MB to the same as the previous generation Core i5.Moreover, it is cheaper than Core i7 and Core i5.In other words, I predict that the reason for pulling out the HT from Core i3 is to make the prices of the top CPUs of other generations, because of the price that cannot be changed.

Comparison between Kaby Lake-S and Coffee Lake-S.The deficit is where the numbers rose.

　Also, the Core i7-8700K seems to have had a problem similar to the 8th generation Core i3 due to the increase in physical cores.The first price of the previous generation Core i7-7700K was $ 339.The top model of the mainstream is SKU that sells the most.Core i7-8700K has a good performance with a good physical cores after a long absence.I want to sell even a little higher than the previous generation to increase sales as much as possible.However, if it is 6 core/12 threads, the number of core/threads will be covered with the "Core i7-7800X" of the top series (Skylake-X), which was just announced in June.

　The first price of Core i7-7800X is $ 389.The price of Core i7-8700K is inevitably less than $ 389, as it is not possible to price higher than the high-ranking segment.So I don't think it was $ 359 between Core i7-7700K and Core i7-7800X.

　So what about the performance of Core i7-8700K?Let's look at the summary in Intel's materials.

Summary of COFFEE LAKE-S.

　Regarding Core i7-8700K, compared to the previous generation's top model "Core i7-7700K", the frame rate of up to 25 % (measured with "Gears of War 4") is high, and Mega Sking (multiple apps (multiple apps).Simultaneous processing is said to be up to 45 % performance.By the way, it seems that this mega -sking is testing with a considerable pressure on the CPU usage rate of recording and distribution at the same time while playing the game "PLAYERUNKNOWN'S BATTLEGROUNDS" (commonly known as PUBG).In addition, the editing of a high -load 4K video will be finished at 32 % at high speed.The increase in physical core is amazing.It's been a long time since the performance has improved by one generation.

　Intel shifts the manufacturing process to 14nm with the 5th generation Core processor.After that, the 7th generation Core processor was planning to miniaturize 10nm, but the technical hurdle was high, and eventually gave up on the Tick-Tock strategy, which makes miniaturization and architecture changes every two generations.However, the 14nm was later improved to 14nm + (Kaby Lake/Kaby Lake Refresh) and to 14nm ++ used in the Coffee Lake.Unexpectedly, I decided to associate with 14nm for a long time in parallel with the development of 10nm.

　The culmination is COFFEE LAKE-S.That's why the performance also improves.I was honestly sorry to think, "It's Coffee Break up to 10nm."Now, let's look at the detailed specifications, such as the corresponding chipset, etc.

The relationship between COFFEE LAKE-S and the new chipset "Intel Z370".

　COFFEE LAKE-S is a new CPU used in combination with the new chipset "Intel Z370".In other words, COFFEE LAKE-S works only on the motherboard equipped with Intel Z370 chipset.Also, as already reported in various places, the CPU socket adopts LGA1151, but has no electrical compatibility with the previous generation CPU.In addition, the chipset that can be used with COFFEE LAKE-S will also appear in the Intel Z370, and other chipsets at a later date as the Intel 300 series.

　Regarding Intel Z370, there is no particular change from the Intel 200 series, such as the support of Optane Memory and Thunderbolt 3, and it is OK to recognize it as a chipset where Coffee Lake-s moves purely.

The 8th generation Core processor has announced a U processor for mobile notebook PCs on August 21.The top model for desktops will be released on October 5, and other models will appear in the first half of 2018.

Core i7-8700K (left), Core i5-8600K (center), Core i3-8350K (right) package.Because it is thinner than Muji, the model number with K seems to be sold separately for the model number with K this time.

Core i7-8700 (left), Core i5-8400 (center), Core i3-8100 (right) package.This seems to be included with the CPU cooler.

　The 8th generation Core processor for desktop PCs, which has increased the number of physical cores and dramatically improved performance, has caused a Core i7, which seems to be comparable to Core I3 and Core X series, which were lower classes, seemed quite affordable.Would you like?In particular, Core i3 is the same as the previous generation Core i5 because there is no TB.If you buy a K and overclocks, you will go up to the performance that can compete with the 7th generation Core i5.No, it's a good era.

　It seems that it is not an exaggeration to say that it is not the remarkable breakthrough of the competition, and it is "thanks to AMD" that did the "Mainstream CPU physical core increase", which did not go for many years.This year is the end of September and only three months left.We are looking forward to the year -end sales war as soon as possible.
