Hello everyone,
My question is straightforward: what can I achieve with an OC i5 6600k? What real advantages does it bring?
I looked at some benchmarks, but they don’t show much improvement compared to the cost. For example, in gaming tests, the difference was only about 10% average FPS, and upgrading from 6600 to 6600k (to 4.5GHz) only added roughly that same percentage.
Given the $200 price of an i5 6500 and the around $280 cost for a 6600k with all components, it’s hard to see why spending 40% more would be justified by just a 10% boost.
I’ve never done an OC before, nor do I have much personal experience. I’m just trying to decide what’s best for my new build and would appreciate the advice of people who know more about this.
The magic question has been discovered! For certain individuals, that additional 10% can mean the difference between life and death. For others, it would go unnoticed by most.
The problem arises because on an Intel quad core, the CPU rarely becomes the main constraint. It's possible to have a processor significantly faster than a 6500, yet only notice a slight boost in FPS. In most games, the GPU handles most of the work, so the CPU just needs to be sufficiently responsive—something any Intel i5 2nd gen quad core or better can manage (again, this usually holds true in most scenarios).
If you achieve 4.6Ghz on a 6600K, that's a 1.4Ghz improvement over the base 6500, offering a substantial clock speed advantage for CPU-bound operations. This translates to more than a 40% increase in performance for tasks limited by the CPU.
Encoding videos with and without an overclock will likely show similar scaling based on clock speed. Gaming doesn't demand as much from the CPU.
Just want to mention another point about how long these setups can actually last. Many users are seeing gaming rigs hold up for 4 to 6 years, especially after swapping out the GPU. You could argue that getting a custom-built 6600K might add just 30 to 40% more performance, which could easily extend the lifespan of the system by another couple of years. That could turn that $80 to $100 investment into a solid return. The other side is that you could opt for a 6500 and spend the same amount on a better graphics card right away, getting immediate gains. It really comes down to what you value more: longevity or immediate performance boost.
So, when it comes to a quick overview, OC would be most beneficial for tasks that require heavy processing, such as rendering videos or using demanding applications (though these are limited in number and mainly aimed at professionals like designers and engineers). For gaming, an i5 6500 (or possibly a 6600 if on sale) could handle the workload for a while, even with some computational needs.
I think I could keep this i5 for several years, and maybe upgrade to an i7 7700k in about three years or so, since the LGA 1151 socket remains compatible. This would help me stay current with the system for at least 7-8 years without needing major overhauls—unless quantum computing becomes a reality.
This seems like a solid plan, doesn’t it? I don’t want to invest more money in something I’ll only use for gaming and light work. I do a translation job but have a laptop for that.
MaxZeta summarized the situation by saying the OC would be most beneficial for tasks that require heavy processing, such as rendering videos or running demanding applications—especially professional tools used by designers and engineers. For gaming, an i5 6500 could handle the workload for some time, even if it means upgrading later to a newer model like the i7 7700k when prices drop. He believes this approach makes sense because he doesn’t plan to use the system extensively beyond gaming or light work, and he’d prefer not to invest heavily in something he won’t fully utilize. He also notes that while older CPU upgrades in the same socket were sometimes worth it, they’re no longer a viable option due to Intel’s performance improvements and the limitations of non-K processors. The advice is to focus on current needs and be prepared for future upgrades if necessary.
1. gaming requires a lot of effort, and since timing matters (you need precise calculations immediately), speed is crucial. A minor slowdown in video encoding won’t be noticeable because it doesn’t affect real-time performance.
2. the 7700k won’t cost less than the 6700k; the older 6700k models might drop by $20 to $40, but they usually run out of supply quickly, so there’s no point in wasting stock.
Everyone tries to explain why an update is planned, but few actually follow through.
