Why is Intel i9 processor better than i7? Lets make some comparisons!
They were introduced in May 2017 for LGA 2066 chips, also known as Intel Core X-series processors.
With their high number of cores, high power draw, high thermal output, and high performance,
they are intended to be used by enthusiasts like the earlier Core i7 Extreme processor.
Here are some general features of Intel Core i9 processors:
Cores and Threads: Core i9 processors typically feature a higher number of cores and threads compared to lower-tier Intel processors. They often have eight or more cores, allowing for efficient multitasking and parallel processing.
Hyper-Threading: Hyper-Threading technology is commonly present in Core i9 processors. This enables each physical core to handle two threads simultaneously, improving overall performance in multi-threaded applications.
Clock Speeds: Core i9 processors generally have higher base and boost clock speeds, providing better performance in single-threaded tasks and applications that benefit from high clock speeds.
Cache Size: Core i9 processors often come with a larger cache size, which helps in reducing memory access times and improving overall system responsiveness.
Turbo Boost Technology: Intel’s Turbo Boost technology allows the processor to dynamically increase its clock speed when needed, providing a performance boost for demanding tasks.
Thermal Design Power (TDP): Core i9 processors typically have a higher TDP compared to lower-tier processors, meaning they may generate more heat and require robust cooling solutions for optimal performance.
Use Cases: Core i9 processors are well-suited for resource-intensive tasks such as video editing, 3D rendering, gaming at high resolutions, virtualization, and other professional applications that demand significant computational power.
The i9-13900KS is the highest-end option, with a higher base clock speed of 3.2 GHz, and an even higher turbo clock speed of 6.0 GHz. It also has the highest TDP of 150W, which may result in more heat generation.
In terms of price, the i9-13900 is the most affordable option, while the i9-13900KS is the most expensive.
i9 is consumer CPU and latest series, 13900, has in total 24 cores with 32 threads. To be more precise, it has 8 P cores and 16 E cores (P cores have 2 threads).

Now we will make a comparison between i9 and i7 processors:
Core Count and Threads:
Core i7: Generally offers a range of 4 to 8 cores and 8 to 16 threads.
Core i9: Typically provides more cores and threads, often ranging from 8 to 18 cores and 16 to 36 threads.
Clock Speeds:
Core i7: Typically has slightly lower base and boost clock speeds compared to i9 processors.
Core i9: Generally features higher clock speeds, especially in boost mode, which can result in better single-threaded performance.
Cache Size:
Core i7: Comes with a good-sized cache, but usually smaller than that of i9 processors.
Core i9: Tends to have a larger cache, helping improve memory access times and overall system responsiveness.
Hyper-Threading:
Core i7: Many i7 processors support Hyper-Threading, allowing for better multitasking with simultaneous execution of multiple threads.
Core i9: Typically features Hyper-Threading across all cores, providing even greater parallel processing capabilities.
Intended Use Cases:
Core i7: Well-suited for high-performance computing tasks, gaming, content creation, and multitasking. It strikes a balance between performance and cost.
Core i9: Designed for enthusiasts and professionals who demand extreme performance. Ideal for demanding applications such as 3D rendering, video editing, virtualization, and other heavily threaded workloads.
TDP (Thermal Design Power):
Core i7: Generally has a lower TDP compared to i9 processors, meaning they may produce less heat.
Core i9: Often comes with a higher TDP, requiring robust cooling solutions for optimal performance.

Like many other components Intel i9 processors have their weaknesses:
High Cost:
Intel Core i9 processors are typically high-end CPUs, and they come with a corresponding high price tag.
his can make them less accessible for users on a budget.
Power Consumption and Heat Generation:
Higher-end processors, including the i9 series, tend to have a higher thermal design power (TDP).
This means they can generate more heat, requiring robust cooling solutions. Additionally, the increased power consumption can impact overall system power efficiency.
Compatibility and Motherboard Requirements:
Some i9 processors may have specific platform requirements and socket compatibility.
Users need to ensure that their motherboard supports the particular i9 model they intend to use, and this may involve additional costs if upgrading from an older platform.
Diminishing Returns for Gaming:
In gaming scenarios, the performance gains of a high-end i9 processor may not always justify the additional cost compared to a high-end i7
or even i5 processor. Games often rely more on single-threaded performance and GPU capabilities.
Limited Performance Gains in Certain Workloads:
While i9 processors excel in multi-threaded workloads such as video editing, 3D rendering,
and scientific simulations, for tasks that primarily rely on single-threaded performance, the gains may not be as pronounced compared to lower-tier processors.
Availability and Rapid Technological Advancements:
The cutting-edge nature of i9 processors means they may not be as readily available as lower-tier processors.
Additionally, the technology landscape evolves quickly, with newer generations being released relatively frequently,
potentially making recently purchased i9 processors seem outdated sooner.
