What customers say about "Details"

Intel Core i7-6700K Desktop Processor

It doesn't run hot even when under load and turbo boosts normally to 4.2 GHz automatically as well.
Got it at a good oc of 4.25 very fast and really good integrated graphics.
The onboard HD 530 graphics are awesome. This is a great investment and the core of a machine that will be kick-ass for years.
This is a super smart and solid option for gamers because of its high speed (4.2 turbo boosted) and unlocked allows you to squeeze even more free performance out of it.
Great CPU, really fast. Great socket.

Intel Core i7-9700K Desktop Processor

I have this with a Prime Z390-A mobo and an RTX 2060 Super GPU, and all new games so fun look and run marvelously on max settings.
Amazing CPU. Works amazing with a msi z390a pro motherboard.
Works well with the latest games without problems.
The CPU works great and is a beast I highly recommend it. Easy to install.
Not the correct socket, no intel markings.

What customers say about "Technical Specifications"

Intel Core i7-6700K Desktop Processor

I7 quad core processor will be more than enough muscle for any and all modern games, and probably leave your gaming rig sitting pretty years of games considering that games are much more gpu dependent.
This is a super smart and solid option for gamers because of its high speed (4.2 turbo boosted) and unlocked allows you to squeeze even more free performance out of it
Quad cores also allow worry free gaming performance while still being able to run other programs and not take a hit in performance when your computer is under a heavy workload!
Awesome cpu, really fast and good temperatures.
Seems to run hot, even with multiple thermal paste applications.

Intel Core i7-9700K Desktop Processor

I installed this on the Gigabyte Aorus Z390 Pro because it has good VRMs and supports up to 5.0GHz overclocking.
Really great CPU. This chip overclocked pretty easily.
Perfect CPU for gaming and multitasking.
Overclocking is fine, and temps are great with the h100i pro.
No issues with temps so far - currently using an NZXT AIO water cooler.

What customers say about "Cache And Memory Specifications"

Intel Core i7-6700K Desktop Processor

The CPU has 8MB of smartcache that is shared amongst the cores. This is much better than normal cache, it allows a program in cache to be shared with another core, when the thread jumps to a new core, without copying the data to another location in cache.
Fast processor when powered with a good socket 1151 motherboard and enough memory.I have an ASRock Fatal1ty Z170 board and 32GB corsair DDR4 memory as well as a smile on my face
Everything is faster opening and switching programs games are amazingly faster was surprised how much better they ran maxed out with this chip. But also this makes the jump to DDR4 so memory has been tremendously improved stock memory is 2.2Ghz to 2.4Ghz.
It works fast, stays cool, and the ddr4 memory helps things stay zippy.
Would have been nice to have 12MB or more of cache, but the cost would have been significantly more. For the price, there is really no downside to this CPU.

Intel Core i7-9700K Desktop Processor

The MSI board offers a very simple overclocking tool, and almost immediately I was running at 4.6ghz on the CPU and 3000mhz on the memory.
The system is very quiet. Great memory performance.
Paired with 3000mhz DDR4 memory I am now getting steady FPS range around 108.
Working great with new MB and memory.
Excellent memory compatibility. Amazing performance.
