I5 Quad Core

Beginning in October 2017, Intel released their latest line of desktop processors, Core i 8th Generation, with Coffee Lake architecture. This new line of desktop processors is the successor of Core i 7th Gen., with the architecture of Kaby Lake, which was introduced early in 2017. Some time ago, we have released the best processor review article Core i 8th Gen., especially if not Core i7-8700K. However, not just one processor that's just Coffee Lake who had stopped at the lab. our test. Yes, we also get a Core i5-8600K loan, and here are our reviews regarding the middle-class processor!

Core i Coffee Lake line can be said to bring a big change, given that Intel finally changed the core configuration on Core i3, Core i5, and Core i7 processors in this new processor family. Broadly speaking, at least for the processors they have announced, Core i 8th Gen. will carry two more cores per line. Core i3 now comes as a quad core processor without Hyper Threading, Core i5 as a hexa core processor asked Hyper Threading, and Core i7 as a hexa core processor with Hyper Threading. In this article, we will focus on Core i5 Coffee Lake.

Intel Core i5 8th Generation

Core i5 8th Gen. this is a very interesting middle-class processor from Intel. How not, Intel has revamped the core configuration in this processor, thus offering two more cores than the common ones they offer in the previous generation Core i5. Today, the Core i5-8600K comes as a hexa core processor, without Hyper Threading, upgrading from a common Core i5 quad core configuration without Hyper Threading as we know it.

Here is a brief specification of the Core i5 8th Gen processor. presented by Intel in early October 2017:

Especially for this article, we will review the performance of the highest processor of Core i5 8th Gen. which exists today, namely Core i5-8600K. Code "K" in this processor again indicates that this processor brings unlocked multiplier. The following is a specification of Core i5-8600K based on the information displayed by the CPUz app:

Specifications: Core i5-8600K vs Core i5-7600K vs Core i7-7700K

As a comparison for Core i5-8600K "Coffee Lake", we present two Intel Core i 7th Gen. The first processor is the Core i5-7600K, the predecessor of the Core i5-8600K whose position will be replaced by this new processor. Meanwhile, the second comparator, Core i7-7700K, we present to see whether Core i5 Coffee Lake can compete with Core i7 from the previous generation, moreover with the presence of a new configuration that carried Core i5-8600K this.

The following table specifies the three processors:

As we mentioned earlier, Core i5-8600K is different from Core i5 for desktop PC previously released by Intel. During this time, Core i5 is always present in quad core configuration without Hyper Threading, or dual core with Hyper Threading for certain variants. Now, Core i5 8th Gen. comes with a hexa core configuration, asked Hyper Threading. This configuration makes Core i5-8600K can offer more cores than Core i5-7600K and Core i7-7700K, but with fewer threads than Core i7-7700K because the processor comes with Hyper Threading feature.

Talk related clock, Core i5-8600K comes with base clock lower than Core i5-7600K, which is 3.6 GHz versus 3.8 GHz. As for the boost clock, Intel sets a higher clock for the Core i5-8600K, good for all core turbo (4.1 GHz vs 4.0 GHz) and single core turbo (4.3 GHz vs 4.2 GHz). However, this clock boost is still below what is offered by Core i7-7700K.

All of these processors use 14 nm fabrication, and are certainly manufactured by Intel itself. One thing to note, Intel did mention that these three processors use LGA1151 socket, but the processor Coffee Lake / Core i 8th Gen. can not be used on existing LGA1151 motherboards. The new motherboard, with the Intel 300 Series chipset, is multi-functional for Core i 8th Gen.

Intel is converting standard RAM support to Core i 8th Gen., where Core i5-8600K offers "official" support for DDR4-2666. Previously, Intel only offered "official" support for DDR4-2400 only, such as those in Core i5-7600K and Core i7-7700K. However, of course this "official" support does not mean Core i5-8600K can not run RAM with speed above it. Like its predecessor from Core i 6th Gen. and Core i 7th Gen. with unlocked multiplier, Intel's latest processor also supports DDR4 RAM at speeds above DDR4-2400 / DDR4-2666. This we will review in separate articles.

LGA1151 for Core i 8th Gen.

Due to certain limitations, related to the "new" specification of Core i 8th Gen. Intel requires the use of a new chipset, Intel 300 Series, for Core i 8th Gen., so the use of a new motherboard is mandatory for this new processor. Uniquely, the presence of the obligation to use the new motherboard is not coupled with the use of new sockets. Yes, as we mentioned above, Core i 8th Gen. it still uses LGA1151, but it is not compatible with Intel 100 Series and 200 Series motherboards.

So far, Intel has just announced a single chipset for this 300 Series Intel line, the Z370. Intel Z370 offers things more or less similar to its predecessor, Intel Z270, including 24 lane PCIe 3.0, USB 3.1 Gen. 1, USB 2.1, SATA 3.0, Thunderbolt 3, and support for Intel Optane. In addition, Intel Z370 chipset also supports the practice of overclocking, utilizing unlocked multiplier Core i 8th Gen. K Series.
