Our Tested Benchmarks
Below, you will find the Cinebench R23 score, gaming FPS, and power consumption of my picks for the top CPU for RTX 4080 SUPER:
Important CPU Key Terms
- TDP: Abbreviated as Thermal Design Power, the TDP of a CPU describes how much heat it generates as opposed to the value being measured as its power consumption requirement. Therefore, your CPU cooler’s TDP should always be higher than your CPU’s.
- Overclocking: The term refers to when users manually increase their CPU, GPU, or RAM speeds outside their factory-set limits. Overclocking can result in greater performance, but it can also cause permanent damage to the overclocked component.
- Cores: CPU cores are processing units that run independently and separately execute tasks within the CPU. Modern-day processors have multiple cores, which help increase their collective performance.
- Cache: A CPU has three types of cache: L1, L2, and L3 cache. All three are small amounts of fast-speed memory that save locations and addresses of directories opened repeatedly by the processor.
- Threads: Threads are categorized as the smallest program units the processor executes separately. A higher thread count indicates better multitasking performance that the processor can achieve.
- Clock Speed: A CPU’s clock speed indicates the number of cycles it can complete within a second. While higher clock speeds usually imply better performance, you also need faster IPC (Instructions Per Clock) performance to make the most of the higher cycle speeds.
How We Picked & Selected The Best CPU For RTX 4080 Super
There are many things you must consider before choosing your preferred CPU. From performance, thermals, pricing, overclocking potential, future-proofing, and compatibility, it can get tough to understand what to look for in a processor. Therefore, these were my considerations while choosing the CPUs for the RTX 4080 Super:
- Performance: The performance of the CPU is the most important factor you must consider when choosing which one you should purchase. This is because it is easy to mess up your CPU and GPU combo, which can result in bottlenecking. So, ensure your CPU doesn’t bottleneck your GPU and vice versa.
- Thermal Efficiency: You should know how much cooling your CPU requires before purchasing to ensure your current CPU cooler doesn’t thermal throttle it if you’re not looking for a cooler upgrade. Higher-end CPUs usually require AIO coolers, while budget CPUs are fine with air coolers.
- Price: Price is another important aspect to consider. You must choose a CPU based on your budget. While high-end CPUs definitely provide better performance, they can have less value due to their price. Therefore, you should consider the CPU’s value while considering its price tag.
- Future Proofing: A processor’s future-proofing is considered through how long it can last before stuttering in newly released games and programs. Moreover, a long-lasting socket also helps improve the CPU’s future-proofing and overall value.
