CPU bottleneck
An Intel Core i5-9400F processor with 2x8GB of RAM should resolve my issues and provide the performance I desire for 1080p gaming at 60 frames per second.
You will also require a new motherboard, and replacing it necessitates a fresh Windows installation to avoid diminished performance.
Determine your motherboard’s make/model to ascertain compatible CPU upgrades.
Assess whether your CPU is a bottleneck by testing with your games, lowered resolution, and reduced visual settings. If FPS increases, your CPU can handle higher graphics configurations. If FPS remains unchanged, you are likely CPU-limited. Games frequently rely more on single-threaded performance than graphics card performance.
Regarding RAM, 8GB is typically sufficient for gaming unless multitasking simultaneously. Examine task manager’s hard fault page statistics to identify a hard fault, which occurs when a game requires code not in RAM and retrieves it from the page file. This is detrimental if your page file resides on a traditional hard drive. Excessive hard faults, such as 0.5 per second, signify insufficient RAM and necessitate adding more memory.
If you have a CPU limitation, it likely stems from the i5-7400’s single thread performance. The i5-7400 has a PassMark rating of 7331 with a single thread rating of 1949. The i7-7700 has a rating of 10731/2346. Your motherboard supports an i7-7700K, which cannot be overclocked, but its stock clocks provide a rating of 12035/2583. Performance gains beyond four threads are uncertain and will vary by game. Any significant CPU upgrade will require a different motherboard.
And what about my RAM statistics that I provided you, is it impeding performance?
Increasing RAM to 16GB is straightforward, but acquiring a 7700 processor is proving challenging.
Insufficient RAM is hindering your performance. Utilizing a hard drive page file can cause delays, with each hard fault taking approximately 0.05 seconds. At a rate of 2-5 faults per second, this translates to a 10-25% decrease in CPU performance. Consider purchasing a 2 x 8GB RAM kit to improve your system’s responsiveness, and this upgrade can be revisited if a new CPU/motherboard is needed in the future. Do you have a solid-state drive for Windows?
Unless a 7700(K) can be found cheaply, consider the 9400F/B365 (or B360 with updated BIOS), which often surpasses the 7700(K) in Passmark. If you are near a Microcenter, you may be able to receive a $30 discount on a CPU/MB bundle (potentially including memory).
