Intel Core i7-9700K with 8 cores and up to 4.9 GHz
Intel has mainly focussed on gamers with the introduction of the 9th generation of its Core desktop processor series. At the same time, the new processors seek to challenge Intel’s arch-rival AMD who released the powerful octa-core Ryzen 7 2700X earlier this year.
Previously, Intel has only been able to release consumer desktop processors with up to 6 cores and 12 threads, which made chips such as the Intel Core i7-8700K technically inferior to the Ryzen 7 2700X in multi-threaded applications. The 9th series Core desktop processors have changed this and now feature up to 8 cores and 16 threads. We reviewed the Core i9-9900K about a month ago, which stormed to the top of comparison tables as the fastest octa-core processor that we have ever tested.
Intel has also introduced the Core i7-9700K and Core i5-9600K alongside the Core i9-9900K, the former of which will be the focus of this review. All three processors are based on the same DIE and are manufactured using a 14 nm ++ FinFET process with a soldered heat spreader. The 9th series Core desktop chips should dissipate heat better and faster than the Core i7-8700K could. We understand why Intel has chosen to now solder heat-spreaders to its CPUs as excess heat quickly became an issue when we tried overclocking the Core i7-8700K.
The Core i9-9900K is the only CPU of the 9th generation Core desktop processors to support Hyper-Threading, but the Core i7-9700K and Core i5-9600K should still perform well in multi-threaded applications. Principally, games benefit more from higher clock speeds than they do from more cores, so most games will not take advantage of the extra power that processors such as the AMD Ryzen Threadripper 2970WX can deliver with its 24 cores and 48 threads. Intel processors also have comparatively high instructions per cycle (IPC), which will help with single-threaded applications such as games.
We will clarify how well the Intel Core i7-9700K performs compared to its AMD and Intel competition in the sections below. We would like first to thank Caseking though, which generously provided us with two test CPUs, without whom we would have struggled to write this review.
An overview of the 8th and 9th generation Intel Core CPUs
Model - 8th generation | Cores/Threads | Base Clock | Turbo 1/2/4/6/8 Cores (GHz) | L3 Cache | Graphics | TDP | Launch Price |
---|---|---|---|---|---|---|---|
Intel Core i7-8700K | 6/12 | 3.7 GHz | 4.7/4.6/4.4/4.3 | 12 MB | UHD 630 | 95 W | US$359 |
Intel Core i5-8600K | 6/6 | 3.6 GHz | 4.3/4.2/4.2/4.1 | 9 MB | UHD 630 | 95 W | US$257 |
Model - 9th generation | Cores/Threads | Base Clock | Turbo 1/2/4/6/8 Cores (GHz) | L3 Cache | Graphics | TDP | Launch Price |
---|---|---|---|---|---|---|---|
Intel Core i9-9900K | 8/16 | 3.6 GHz | 5.0/5.0/4.8/4.7/4.7 | 16 MB | UHD 630 | 95 W | US$488 |
Intel Core i7-9700K | 8/8 | 3.6 GHz | 4.9/4.8/4.7/4.6/4.6 | 12 MB | UHD 630 | 95 W | US$374 |
Intel Core i5-9600K | 6/6 | 3.7 GHz | 4.6/4.5/4.4/4.3 | 9 MB | UHD 630 | 95 W | US$262 |
Prices & Availability
Prices of the new processors have relaxed in recent weeks. We saw the Core i7-9700K online for €499 (~$564) last month, but Caseking is now selling the CPU for €429 (~$485). This represents around a 15% price drop in a few weeks and is a trend that we hope will continue for the sake of end users looking to buy a new processor. The Ryzen 7 2700X is still around €100 (~$113) cheaper than the Core i7-9700K though.
The Test System
We used the ASUS ROG Strix Z390-E Gaming as the basis of our test system and paired it with 16 GB of DDR4 RAM from G-Skill. The RAM clocks at 3,400 MHz and was set as an XMP profile in the BIOS. We left all other BIOS settings untouched until we tried overclocking the CPU. Caseking kindly sent us a Raijintek AIO that has a 360° radiator. The company also supplied us with an open-frame Raijintek case, to which Caseking added the Notebookcheck logo, which is a nice touch.
We also equipped our test system with the same GPU that we used for our Ryzen 5 and Ryzen 7 reviews to provide more consistent results against which we could compare the Core i7-9700K. We have included the power consumption of these components in our power consumption tables in subsequent sections.
We installed Windows 10 on a 240 GB SanDisk Ultra II. We would have liked to have used the 512 GB ADATA SX910 drive that we used in our Core i9-9900K review, but unfortunately we had to return the drive because of a defect. We have also equipped our test system with a 480 GB Intel Optane SSD 905P drive, which connects via an M.2 slot on the motherboard and utilises the NVMe protocol for fast data transmission. We decided to store games on a Samsung Evo 850 500 GB SSD and a Western Digital 2 TB HDD, which were both connected to our test system via USB 3.0 for the purposes of our tests.
An overview of our Test System
ASUS and Caseking supplied us with the following hardware for our benchmarks and tests:
- Intel Core i7-9700K and Intel Core i7-9700K Advanced Pre-Test Edition
- ASUS ROG Strix Z390-E Gaming (BIOS 0506, Default Settings, XMP 1 for DDR4-3400)
- G-Skill Sniper X DDR4-3400 2 x 8 GB
- Raijintek Orcus 360 (AIO)
- Raijintek PEAN Benchtable
We also used the following hardware:
- XFX AMD Radeon RX Vega 64
- LC Power 1,200 W Power Supply
- SanDisk Ultra II 240 GB
- Intel Optane SSD 905P 480GB
- Samsung Evo 850 500 GB (for games)
- Western Digital 2 TB (for games)
CPU Benchmarks
The Core i7-9700K is currently Intel’s third fastest CPU behind the Core i9-7900X and the Core i9-9900K according to our CPU benchmarks. While the Core i9-9900K is technically superior to the Core i7-9700K with its Hyper-Threading support, it only scored 11% more in our performance rating test. The Core i7-9700K also scored just 2% less than the Core i9-9900K in the Cinebench R15 single-threaded benchmark. However, the Core i7-9700K finished 30% behind its more powerful 9th generation sibling in the multi-threaded portion of Cinebench R15. Generally, the inclusion of Hyper-Threading adds a measurable increase in performance in synthetic benchmarks, but we suspect that most people would not notice the difference in daily use.
The Core i7-9700K even performs well against AMD Threadripper APUs in certain benchmarks. Overall, all the Threadripper APUs in our comparison tables significantly outscore their Intel counterparts in multi-threaded benchmarks. By contrast, Intel still has the edge in single core performance over AMD, with the Core i7-9700K finishing 17% ahead of the highest scoring Threadripper APU in our Cinebench R15 single-core benchmark comparison table.

Cinebench R15 multi-core benchmark loop
We also subjected the Core i7-9700K to a Cinebench R15 loop to test how well it can maintain its performance under sustained load. As the graphs below demonstrate, our test CPU performed consistently even after around 30 minutes and 55 pass-throughs of the looped benchmark. Please keep in mind that your experiences may differ as we conducted our tests with an open test case, during which the Core i7-9700K core temperatures hit the critical 100 °C (212 °F) mark.
Our test CPU averaged 4.6 GHz across all cores during the looped Cinebench R15 benchmark, which tallies with Intel’s specifications for the Core i7-9700K. Our test system averaged just shy of 200 W during this stress test for reference. In short, desktop processors such as the Core i7-9700K generally have fewer problems with maintaining their peak performance during a looped Cinebench R15 benchmark than equivalent notebook processors do.

Gaming Performance
The Core i7-9700K is almost equivalent to the Core i9-9900K in gaming benchmarks. The two processors are separated by only a few points in the performance rating. Please keep in mind that the Core i9-7900X consistently outscored its Intel counterparts in these tests because of its more powerful GPU and not because it is a better gaming GPU. We have tested most of the desktop CPUs in our comparison tables with the same AMD Radeon RX Vega 64 though, so our tables provide a good basis for comparing the strength of CPUs in games.
The Core i7-9700K cannot match its more powerful sibling in synthetic benchmarks though on account of the Core i9-9900K’s Hyper-Threading support. The Core i7-8700K finished ahead of the Core i7-9700K for the same reason too. However, the latter performs better in gaming benchmarks. Hence, we would recommend taking synthetic benchmarks with a pinch of salt when deciding between components.

Application Performance
The Core i7-9700K also performs similarly to the Core i9-9900K in applications. Both CPUs score solidly and finish in the middle of our PCMark 10 comparison tables, although the Intel CPUs lead the pack in the older PCMark 8 benchmark.
Our test system showed no major weaknesses in daily use, although equipping the system with an NVMe SSD would have made it feel snappier. We doubt that most people would notice the difference during general tasks though, nor will the 8 threads that the Core i7-9700K has become an issue in normal use compared to the 16 threads that the Core i9-9900K utilises. The difference between the two CPUs in multi-threaded applications is noticeable, but this will only become tangible in games when developers start taking advantage of multiple cores. Hence, the Core i7-9700K is perfectly suited as a gaming CPU, although we would recommend looking elsewhere if you need a workstation CPU for running multiple VMs.

Emissions
Intel states that the Core i7-9700K has a 95-W TDP just like the other two 9th generation Core desktop processors. However, we easily exceeded this value in our tests. According to HWiNFO, our test CPU averaged 135 W during a stress test and peaked at 169 W, which is 70 W or almost 50% more than what Intel claims the Core i7-9700K will consume. Additionally, our test CPU throttled back to 4.4 GHz during a stress test as it could not stably maintain its peak output. We would always recommend equipping a system with an AIO where possible because they are more efficient at dissipating heat than air coolers.
We suspect that de-lidding is possible, although the inclusion of a soldered heat spreader makes the process more complicated than on a Core i7-8700K. Caseking sells a de-lidded version for around €669 (~$756) by der8auer, which the company markets as the Advanced Pretested Edition, should you wish to get the most performance possible from your CPU.
Caseking graciously supplied us with an Advanced Pretested Edition of the Core i7-9700K to compare its performance against the normal version, and the results are impressive. The de-lidded can achieve a stable 5.0 GHz across all cores, while core temperatures average around 10 °C (~18 °F) lower than the normal Core i7-9700K. So, de-lidding the Core i7-9700K could result in better performance and lower temperatures, but you would void your warranty in the process. Hence, we would recommend considering the der8auer version as that comes with third-party warranty.
We also took a closer look at the power consumption of our test system in different scenarios. Our system draws about 63 W at idle, which rose to an average of 222 W during a one-hour stress test. The system consumed a maximum of 365 W when playing "The Witcher 3" at 1080p, although the AMD Radeon RX Vega 64 consumes plenty of wattage in this scenario.

Overclocking
The Core i7-9700K has an unlocked multiplier, which means that it is open to some overclocking, with the Z390 motherboard giving us the perfect opportunity to do so. We achieved a stable 4.9 GHz across all cores with our test CPU, but unfortunately it scored 13 points lower in the multi-threaded portion of Cinebench R15 than when we tested it at stock settings. We determined that raising the voltage on our test CPU caused core temperatures to spike, which resulted in thermal throttling and a clock speed reduction to combat the excess heat.
By contrast, the Advanced Pretested Edition achieved a stable 5.0 GHz at 1.34 V and scored 1,525 points in Cinebench R15, which is a 92 point or a 4% improvement over the stock Core i7-9700K. The core clock boost also puts the Advanced Pretested Edition on par with the Core i9-9900K in single-core benchmarks, which is impressive. We would recommend investing in an AIO cooler such as the Raijintek one that Caseking supplied us if you plan to permanently overclock the Core i7-9700K, the reasons for which we will explain below.
The power consumption of our test system increased to 255 W during a stress test with the Advanced Pretested Edition CPU, which is around 50 W higher than what our test system what averaged in the same test. Caseking also sells a Pro and an Ultra version of the preselected processors if the Advanced version is not enough for you. We have included a screenshot of the differences among the three versions; please bear in mind that this is in German.
Verdict
The Intel Core i7-9700K is a powerful and impressive CPU. It is not as potent as the Core i9-9900K, but the octa-core CPU can deliver up to 4.9 GHz on a single core and 4.6 GHz across all cores at stock settings. We would suggest buying a decent cooler though, as the Core i7-9700K ran hot during our tests.
Overall, the Core i7-9700K performs on par with the Core i9-9900K in most scenarios. The additional threads that the latter has will not make a difference in games, but you may notice a difference if you use numerous multi-threaded applications. The Core i7-9700K has a high volume of IPC compared to AMD APUs too. However, Threadripper APUs with at least 12 cores consistently outperform the Core i7-9700K in multi-thread applications and benchmarks.
In short, the Core i7-9700K is the second fastest Intel octa-core processor behind the Core i9-9900K. The Core i7-9700K outperforms its predecessor in games and will deliver solid gaming performance for years to come.
Unfortunately for Intel, AMD APUs are still better value for money. The Core i7-9700K currently costs around €419 (~$473), which is around €100 (~$113) more expensive than the Ryzen 7 2700X. The Core i7-9700K has worse multi-core performance too, although it will outperform the Ryzen 7 2700X in single-threaded applications like games.
Moreover, we would recommend the Core i7-9700K over its more expensive sibling primarily because of the difference in cost. The performance difference between the two CPUs is minor, and you could even use the money saved to buy a more powerful GPU and have a better overall gaming experience.
The Intel Core i7-9700K is the sensible choice of the new 9th generation Core desktop processors. The CPU delivers practically the same performance as the Core i9-9900K, but at a significantly lower outlay. Pocket the difference and buy a better GPU instead.
Another side effect of having a high clock speed and IPC is power consumption. The Core i7-9700K consumes considerably more than its rated TDP, which predictably further increases when the processor is overclocked. Overall, the Core i7-9700K is a fantastic desktop gaming processor at stock settings, so we do not see the benefit from overclocking or de-lidding it. You could always pay extra for the Caseking Advanced, Pro or Ultra Pretested Editions if you want improved performance though.
