Review: Intel Core i5-9600K Coffee Lake Refresh tray [CM8068403874404]

The Core i5-9600K is the cheapest Intel desktop processor in the Coffee Lake Refresh family. It has only six, not eight processing cores, but it is 30-40% cheaper than the younger eight core model Core i7-9700K.

The six cores of the processor have a very interesting story – the processor emerged as a result of the implementation of chips that were a marriage in the production of older Coffee Lake Refresh. That is, the basis of the processor is the same as that of the more expensive versions of the Core i9-9900K and Core i7-9700K, but two of the eight cores were deactivated.

In addition to the crystals from the eight-core counterparts with an area of ​​174 mm2, the Core i5-9600K has a lot more in common with the i9-9900K and Core i7-9700K models. For example, here is the first hardware patch package against the vulnerabilities Meltdown and L1TF (Foreshadow), the memory controller of this processor is certified to support 128 GB DDR4 SDRAM.

Core i5-9600K is produced according to the most modern version of Intel’s 14-nm process technology and has an unlocked multiplier, which allows it to be overclocked. The processor is equipped with an integrated graphics core UHD Graphics 630.

The processor is compatible with any LGA1151v2-motherboards built using Intel chipsets with numbers from the fourth hundred.

Review of Intel Core i5-9600K Coffee Lake Refresh tray [CM8068403874404]

The Coffee Lake Refresh family of the 9xxx series in its current form includes three representatives, of which only two processors have eight processing cores. Another option is Core i5-9600K has six cores, but it uses the same semiconductor base as in the older brothers. It is built on the eight-core semiconductor crystal Coffee Lake Refresh with a pair of deactivated cores.

As a result of the appearance of such copies in production with separate defective cores or partially malfunctioning cache memory – the six-cores processor model of Coffee Lake Refresh.

Core i5-9600K is a six-core processor with solder under the processor cover, which, unlike the Core i5-8600K, does not require scalping in order to accomplish overclocking.

The core i5-9600K, in contrast to the Core i5-8600K, which is similar to the our processor in review, is based on the semiconductor crystal of the P0 modification, not U0, that used in Coffee Generation processors of the previous generation.

In terms of performance and price, the processor offers the lowest unit cost per a single core in the Coffee Lake Refresh processor family.

Acceleration and frequency in turbo mode

If we compare the overclocking potential of the Core i5-9600K in comparison with the Core i5-8600K, then the new six core has 100 MHz higher base frequency and more aggressive turbo mode, allowing to accelerate up to 4.6 GHz with a low flow load unlike 4.3 GHz from its predecessor. It is important to note that with a multi-threaded load created by the Prime 95 29.4 stress test, the actual consumption of the Core i5-9600K in a conditional-nominal mode with active Multi-Core Enhancements at 4.3 GHz will be 115 W.

Core i7-9700K 3,6 4,9 4,8 4,7 4,7 4,6 4,6 4,6 4,6
Core i7-8700K 3,7 4,7 4,6 4,4 4,4 4,3 4,3

Power usage

In Core i9-9900K, Core i7-9700K and Core i5-9600K models, the internal thermal interface material is inserted between the semiconductor chip of the CPU and the processor cover. Instead of polymer thermal paste, metal solder with much higher thermal conductivity is used here.

Comparison of temperature and power consumption of the Core i5-8600K and Core i5-9600K. The overlooked processor demonstrates at equal higher power consumption. Due to the advantage in temperatures, the overclocking potential of the Core i5-9600K is significantly higher than that of the processor based on old chip. In practice, the Core i5-9600K frequency can be raised about 100 MHz higher than for the Core i5-8600K.

CPU overclocking

The maximum frequency at which the processor can work stably and pass stress testing is 5.0 GHz (With VCORE in the range from 1.25 to 1.28 V with the inclusion of the penultimate level Load-Line Calibration). Since the power consumption and heat dissipation of the Core i5-9600K is still at a rather high level, more serious overclocking becomes impossible. If you are planning any overclocking of this processor at all, then you should use good cooling system for it, at least not worse than Noctua NH-U14S.

It is worth noting, however, that the Core i5-9600K is better suited for overclocking than all eight-core Coffee Lake Refresh units.

CPU testing

Testing processor performance in Acrobat Pro DC, Photoshop CC, Lightroom Classic CC, BowPad 2.3, CyberLink PowerDirector 15, FileZilla 3, Chrome 65, Excel 2016, OneNote 2016, Outlook 2016, PowerPoint 2016 and Word 2016 using Sysmark 2018 test applications. 3DMark Time Spy Extreme.

In complex tests, the Intel Core i5-9600K processor Coffee Lake Refresh is about 5% faster than the Core i5-8600K and Core i7-7700K, and only 13% slower than its older eight-core fellow, the Core i7-9700K.

Testing in 3DMark Time Spy Extreme Core i5-9600K showed that the processor in review can offer 18% better performance than the two-year-old flagship processor Core i7-7700K had. However, before the result of a full-fledged eight-core Core i7-9700K, it falls short very much: the older Core i5-9600K model surpasses by 30%.

 

Performance in resource intensive applications

Tests: Rendering in applications Corona 1.3, Blender 2.79b, processing photos in Lightroom, working with video in Premiere Pro CC 2018, Video Transcoding (x265 codec), archiving via 7-zip, encryption via VeraCrypt, Stockfish Chess 9.

In terms of performance in resource-intensive applications, the Core i5-9600K is comparable in performance in applications only to Ryzen 5 2600X

Gaming performance, 4K resolution

As for the tests in FullHD, compared to the Core i7-9700K, the new six-core offers a 10% worse frame rate. The Core i5-9600K turns out to be on average 15% faster than the Ryzen 7 2700X, AMD’s flagship processor for the mainstream platform.

When running games in 4K resolution, the Core i5-9600K processor is significantly inferior to the eight cores only in resource-intensive strategy games, in other cases, the new product demonstrates a close to the leading level of fps.

Customer Reviews

Buyers in their reviews noted good processor performance and good overclocking potential. Users who switched to Intel Core i5-9600K from the previous generation i7 were completely satisfied with the upgrade and announced more than double the speed increase in synthetic tests.

Users found the price of the processor quite high, and high work temperatures were also noted in cases where insufficient cooling was installed. In Russia, the cost of unit is very different from the recommended price.

Do not buy for heavy gaming or streaming
Date of Purchase: January 5, 2019
Let me start off by saying if your building a new pc on a budget do not go with this cpu go with amd Ryzen 2600x it will just be so much better for same price and if you already have a intel motherboard and are looking to upgrade cpu go with the i7 8700k this cpu uses almost 60-80% only playing games like fortnite if you are looking to stream save up and get the i78700k and or amd processor this processor is okay if your not using it to stream or multitask when playing games

Most a reasonable gamer should buy for this socket type.
February 21, 2019 [Verified Purchase]

I settled on this, knowing that I wanted one of the latest generation of processors. After examining benchmarks, there simply wasn’t evidence that a better processor was needed for a gamer with my needs. Plus, this is much easier to keep cool than it’s more expensive cousins, the 9700k and 9900k. For my 1080p 60hz standard of enjoyment this thing kicks butt, and usually isn’t even that taxed by my current needs. I didn’t even overclock it yet because I simply don’t need to yet.

Advice: if you’re gaming and don’t require the best of the best but still want high performance, this is the processor to go with for the next several years (at least from intel).

It was my first processor installation and I had no issues. Make sure to have adequate cooling and a reliable thermal paste application and there should be no overheating issues.

Con: it’s intel so it’s expensive.

Thanks for reading.
