How much i7 is faster than i5?
Key Difference between Intel Core i5 and i7
The clock speed of Core i5 is 1.2-3.6 GHz, while the clock speed of corei7 is 1.3-3.5 GHz. The cache size of Core i5 is 3MB-6MB. On the other hand, the cache size of Core i7 is 4MB-8MB.
The Intel Core i5 is an all-purpose processor that offers solid performance for gaming, web browsing, and doing basic work. The Intel Core i7 has more processing power and is better for high-performance gaming, content creation, multimedia editing, and specialized applications.
As a result, it's overall average speeds end up being lower. Intel has struggled to move their low power chips beyond a quad-core architecture, so both the Core i5 and the Core i7 have the same layout with 4 cores and 8 threads. However, the Core i7 has more cache and a larger GPU, both of which need more power.
The i5 processor offer great value for money if you're looking to game in 2022. However you'll need an i7 to be able to handle more demanding taks. Plus, with an i7 you'll be future-proofed for a few years down the line. So if you can afford it, go for the i7!
The difference in costs between generations is not significant. As for the i7, if you're planning to use it exclusively for gaming, it is probably not worth the price. Core i5 will be just as fast for games, and 6 extra threads won't make a noticeable difference.
Intel Core i7 processors are typically faster and more capable than Core i5 CPUs. The latest i7 chips offer up to six cores and 12 threads, making them better suited for advanced multitasking.
An i7 will likely last a bit longer, but not much. It's way more likely that the single core performance, which is almost identical for the i5 and i7, will be the limiting factor.
It does not make any difference for general usage. Unless you are into applications using multiple cores, like Video editing , gaming and streaming at same time you dont need i7. For gaming i5 is sufficient. So for most people i5>i7 in desktop, because it's cheaper.
Intel® Core™ i7 Processors
These processors power high-end PCs with excellent CPU performance for discrete-level graphics and AI acceleration.
The newer generation Core i7 CPUs can be an overkill UNLESS you game at very high resolution and stream at the same time. In addition to that, popular online eSport titles do not require a powerful CPU. In fact, an Intel Core i3 CPU from a relatively newer generation is quite sufficient for a popular online games.
How many years will i5 last?
How long will an i5 processor last? My i5–2500k lasted me about a decade. If you buy an i5 today it will probably last until 2030 without problems. You can bet that something else in your system will give way first before the i5 will.
For ideal results, a machine running an Intel® Core™ i7 processor or better with at least 8GB of RAM is sufficient for playing games and streaming at the same time. If you're hoping for less impact on your gaming performance, an Intel® Core™ i9 processor makes for an even smoother experience.

A Core i7 will typically be better for multitasking, media-editing and media-creation tasks, high-end gaming, and similar demanding workloads. So, yeah it's worth the extra money.
The largest difference between the i5 and i7 is Hyper-Threading, which is a technology to increase the performance of multithreaded tasks. Hyper-Threading makes the processor appear to have double the cores to the operating system and applications.
Introduced in 2008, the Core i7 line of microprocessors are intended to be used by high-end users.

Long answer, it depends on a lot of factors & even for the same generation, an i5 can be more powerful, happens in laptops where there are 3 types of CPUs with different TDPs, Y (5 W), U (15 W) & H (45W). So for instance, an i5 8300H is better than i7 8550U.
Is older i7 better than newer i5?
Generally, among two consecutive generation of Intel's core series CPUs, the higher end i7 from the older generation has been better than the lower end i5 of the newer one.
The newer generation Core i7 CPUs can be an overkill UNLESS you game at very high resolution and stream at the same time. In addition to that, popular online eSport titles do not require a powerful CPU. In fact, an Intel Core i3 CPU from a relatively newer generation is quite sufficient for a popular online games.
