Intel Core i7-9700K vs Intel Core i7-8700K
When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.
Intel announced its range of 9th Generation Core processors at its Desktop Launch Event 2018, including the new eight-core Intel Core i7-9700K.
This will be the processor that high-end PC builders will want to buy, but how does it compare to its 8th generation predecessor, the Intel Core i7-8700K?
In this article we’ll compare how the two processors stack up against each other, and see if there’s a compelling reason to buy the new i7-9700K over the older, yet still very powerful i7-8700K.
Intel Core i7-9700K vs Intel Core i7-8700K price
The Intel Core i7-8700K launched last year for $359 (about £270, AU$460), which put it directly against AMD’s best Ryzen 7 processors including the $329 (£299, AU$469) AMD Ryzen 7 2700X.
Meanwhile, the Intel Core i7-9700K will cost $374 (around AU$530). In the UK, retailers have pitched it at a higher £500 price tag. The price after tax will be more like $399, if you’ll want the newer, and more powerful, i7-9700K. Of course, those looking to build a high-end gaming PC may already be ready to splurge on the best CPU.
Intel Core i7-9700K vs Intel Core i7-8700K: specifications
This is where things get a little confusing, as the Intel Core i7-9700K comes with two extra cores but a lower thread count than the Intel Core i7-8700K.
So, the Intel Core i7-9700K comes with eight-cores and eight-threads, 12MB cache and a TDP of 95W.
Meanwhile, the Intel Core i7-8700K features six-cores and 12 threads, 12MB cache and a 95W TDP.
The Intel Core i7-9700K is also rated with a base clock of 3.6GHz and can boost one its processor cores all the way to 4.9GHz. Comparatively, the Intel Core i7-8700K starts at a tick higher 3.7GHz base frequency, but can’t go nearly as fast with its maximum 4.7GHz boost clock.
However, it could be in overclocking where the Intel Core i7-9700K will really gain a lead over its predecessor.
Thanks to its soldered integrated heat spreader (IHS), the Intel Core i7-9700K should be better at keeping the chip cool, allowing for better overclocks.
In theory, this purported gold-plated solder replacing the thermal paste Intel has used in the past will be a much more efficient heat transfer medium.
Intel Core i7-9700K vs Intel Core i7-8700K: should you upgrade?
So, should you upgrade from a Intel Core i7-8700K to a Intel Core i7-9700K? We won’t be able to give you a definitive answer until we’ve properly reviewed the new chip and spent time with it, but on paper at least it looks like the Intel Core i7-9700K is a decent upgrade for a reasonably higher price.
It doesn’t look like it does anything that will make the Intel Core i7-8700K obsolete any time soon, though. That may be good news for Intel Core i7-8700K owners, but disappointing for others.

- The i7-8700K has more threads. Larger programs are divided into threads (small sections) so that the processor can execute them simultaneously to get faster execution.
- For some games, a cpu with a higher clock speed, or in a technical name IPC (Instructions per clock), has better results than other CPU’s with higher core count and lower core speed.
i7-9700K
- The i7-9700K has more cores. The benefit of having more cores is that the system can handle more threads. Each core can handle a separate stream of data. This architecture greatly increases the performance of a system that is running concurrent applications.
- The i7-9700K has a higher turbo clock boost. Turbo Boost is a CPU feature that will run CPU clock speed faster than its base clock, if certain conditions are present.
It will enable older software that runs on fewer cores, to perform better on newer hardware. Since games are software too, it is also applicable to them.

Performance
CPU speed
6 x 3.7GHz
8 x 3.6GHz
CPU speed shows how much cycle ov processing per second can be performed by the processor, given all its cores (processors) . It is calculated by adding the clock speeds of each core or, in the case of multi-core processors, each group of cores.
processor thread
More threads result in better performance and better multitasking.
turbo clock speed
4.7GHz
4.9GHz
When the processor is running below its limits, it can jump to a higher clock speed to increase performance.
Has unlocked multiplier
✔Intel Core i7-8700K
✔Intel Core i7-9700K
Some processors come with an unlocked multiplier and are easier to overclock, allowing for better performance in games and other applications.
L2 Cache
More L2 scratchpad memory results in faster results in CPU and system performance tuning.
L3 cache
More L3 scratchpad memory results in faster results in CPU and system performance tuning.
L1 cache
More L1 cache results in faster results in CPU and system performance tuning.
L2 core
0.25MB/core
0.25MB/core
