So I originally had a i5 9600K installed. The chip performed fantastic and ran everything I threw at it buttery smooth. With 9th gen chips currently on sale I picked up an i7 9700F. I installed the new chip, along with a fresh installation of Windows 10 on my SSD. I ensured I had the latest Windows updates and nVidia driver updates.
Upon running some of my favourite games, I noticed quite a bit of micro stuttering with the i7 9700F. Specifically, every 6 - 8 seconds, the screen will freeze for 1 second in Hell Let Loose. In another game, Squad, stuttering will occur on and off when in high pop areas with a lot of effects on screen. These games are military sim type which typically use a lot of cpu power. For the record, non of these issues occurred with the i5 9600K. Temps are good, and never exceed 42C as I'm using a Cooler Master 212 Evo. I ran the Intel Processor Diagnostics Tool and everything passed. I also monitored cpu utilization while running some of these games. All cores seemed to boost to their advertised speed and most utilization was around 60%, with the exception of 1 core that would frequently hit 100%
Why does my i5 9600K perform much better in gaming than the i7 9700F? I know the i7 has a much lower base clock, but it has an all core turbo of 4.4 GHz, where the i5 has an all core turbo of 4.3 GHz. If anyone could shed some light on this issue that would be great. I'm quite disappointed with the performance of this i7. Unsure if this is normal or not.

Thank you for submitting your question on this Intel® Community.
Regarding your questions, Intel Technical support does not discuss about benchmarking and performance because every system configuration is different.
Upon checking more details about this processor, this processor does not have intergrated graphics so all the games that are pleyed are run by the dedicated card that has been installed on your system. The stuttering might be related to optimmizations or configurations that needs to be performed. It's worth mentioninng that there are some games that are more GPU intensive than others so taking in consideration the temperatures are good never exceed 42C, Intel Processor Diagnostics Tool shows that everithing passed and CPU utilization looks fine this might be related to a system set up.
Can you please share the following report:

Thank you for the reply and support. I have provided both pieces of information as requested. Please note, the temps are slightly higher than originally reported because I have removed and reseated the CPU. Yes I am aware this chip does not have integrated graphics. My i5 9600K has integrated graphics, but the games always ran on the GPU with either CPU.
Yes, these are the only two games which I have experienced this issue with. I understand it could be a matter of optimizations, but if that's the case, why doesn't my i5 9600K experience these stuttering issues?
Thanks in advance.
Before running these tests you had requested, I reseated the cpu and installed another fresh copy of Windows 10. Since doing this, the micro stuttering issues I originally reported, are no longer present. Feel free to close this thread. If the issue returns, I will create a new one.
