Intel i5 vs i7: Which Is Better for Gaming Performance?

If you want to build your own gaming PC, there is no question that the first thing you need to do is research. Go online and watch the latest reviews of motherboards, GPUs, RAM memories and other miscellaneous parts you need to build the best gaming computer. However, when it comes to CPUs, there will always be a fierce battle between AMD and Intel. Both offer high-end products suited for complex operations and a lot of computing power.

Should you choose to go with intel, there is yet another dilemma that stands between you and the PC of your dreams. In a one-to-one battle between Intel i5 vs i7 who will be victorious? Both are capable of delivering impressive results. However, only one of these is most suited for you if you only wish to play the latest games.

The Skylake Generation

Although you should not be so quick as to dismiss earlier CPU generations offered by Intel, you should keep in mind one important factor. As opposed to older Intel Core i5 and i7, the Skylake generation comes forth with improved CPU features capable of tremendous computing power. You may also think that purchasing a Haswell chip will save you some money while delivering almost the same results as the new generation.

Well, you’re not entirely wrong. However, go the extra mile and do whatever you can to get your hands on one of the 6th generation’s CPUs. Saving a few dollars now won’t help you much in the long run, if at all. To understand a little better the main differences between older generation chips and the improved i5 and i7, let’s have a look at hyper-threading.

Intel i5 vs i7 Hyper-Threading

Hyper-threading refers to the process of handling more than just one task by each individual core. Instead of queuing processes up for execution one-by-one, the threads are able to manage multiple tasks simultaneously. As a result, the CPU speeds everything up and you will finish whatever you are working on much faster. The more threads, the better. This is because Windows will recognize them as physical cores and allows software to use them as such. However, they don’t come near the power an extra physical core provides, but are still useful when working with demanding software.

With all of that being said, let’s see what Intel’s Core i5 has to offer when it comes to hyper-threading. Unfortunately, you will not be able to benefit from this feature on an Intel Core i5 desktop chip. However, hyper-threading is available for i5 mobile dual-core processors. When it comes to the stronger counterpart, all Intel Core i7 processors benefit from hyper-threading. This means they can handle twice as many hyper-threads as they have cores. Although it sounds pretty awesome, hyper-threading is highly dependent on software. This means that only some applications that are especially designed to take advantage of hyper-threading will improve the overall computing power. If you work a lot with video and photo editors, the i7 is definitely the best fit for you.

Clock Speed: Intel i5 vs i7

Each processor works at different speeds. The faster they process information, the better. This is more commonly known as clock speed. Although it is safe to assume that higher processing speeds build up to a better overall performance, this has become less relevant over the last decade. This is because different CPUs can handle a series of operations at a different rate, even though they benefit from the same clock speed. However, when it comes to Intel i5 vs i7, they both operate based on the same architecture. In this case, whichever benefits from a higher clock speed is the winner. Or is it?

Intel Core i5 uses a frequency of 3.2 GHz, while the i7 can go as high as 4.0 GHz. However, this doesn’t automatically make the i7 superior to the i5. The secret lies in the number of physical cores. It is possible that sometimes quad-cores have lower clock speeds than dual-core processors. This is more common for mobile chips that use up less space. Hence, even though they benefit from a higher clock speed, a desktop dual core will most certainly win every time you run applications that don’t require many cores. As a result, if you’re looking to build yourself an awesome gaming PC while staying in the budget, the i5 is best for you.

Intel Turbo Boost

In addition to high clock speeds, Intel processors come with a great feature called Turbo Boost. This enhances the overall performance of the CPU under stress conditions. When it comes to web browsing or other application that use up only two cores, this feature won’t have much of an effect on the overall performance. However, the Turbo Boost is best put to use if you use resource-intensive software like video games or photo and video editors.

Basically, the Turbo Boost increases the clock speed when either some of the cores are sitting idle or the power use is low. Keep in mind that quad-cores boost more aggressively than dual-core CPUs. This means a visible improved performance when the processor runs at full throttle.

Intel i5 vs i7 Cache Memory

As opposed to the Intel i5, the i7 benefits from a bigger cache memory. And the difference between the two of them is only 2MB. Normally, you wouldn’t think that this may be enough to settle the score between Intel i5 vs i7. However, this extra 2MB of cache memory makes all the difference in the world and one of the most notable contrasts between them. Before going on about this particular aspect that sets the i5 and i7 apart, let’s help you better understand the importance of cache memory.

Benefiting from cache memory means that you can store the most used processes in a small virtual memory other than the RAM. You can say it’s almost like a short term memory where you store only the essentials. As a result, the RAM memory, where more important processes are stored will not be overcrowded. If this happens, the overall performance of the computer can suffer greatly. Hence, the bigger the cache memory is, you will be able to store multiple simple processes that will improve the overall performance of your PC. Although it is only 2MB larger than the i5’s cache memory, this feature is designed to speed up the repetitive processes, lower power use and the RAM memory demands altogether.

Heat and power: Intel i5 vs i7

If you truly want a great gaming experience, go for a PC. Not because laptops are in any way inferior, but because there are two main things that clearly set these two apart: space and size. It is true that the laptop is perfect to take with you anywhere you go and all that. However, when you put a lot of stress on the CPU it should come as no surprise that it will start to heat up. Not only the chip but the graphics card as well. When this happens, there is not much you can do but to take it a little bit easier with the gaming. The bigger the computing power of the processor, the greater the heat. Hence, the i7 burns at higher temperatures when running demanding software and also uses more battery power. All of this for quite an insignificant improvement in the overall gaming experience.

Again, if you are going to use your computer for video editing, the i7 is by far the best buy. However, if you’re looking just to experience the best games on the market, there is no need to go higher than an i5. Also, since we’re talking about gaming, go out of your way and make yourself a gaming PC. This cannot be stressed enough. Even though a laptop that features a Core i5 CPU is great for supporting the latest appearances, think about how much more a PC can deliver. For example, an overclocked desktop i7 runs at no higher than 60 degrees with proper cooling. This is certainly going to have a say in the overall gaming experience. Together with the extra space and bigger parts, your computer will benefit from an improved airflow which will keep everything cool and enhance the lifespan of the CPU.

Intel Core i7 Extreme Edition

In terms of hyper-threading, clock speed, and cache memory, the Intel Core i7 already seems like the best CPU on the market capable of doing just about anything. As if this wasn’t enough, the Intel Core i7-6950X extreme edition is now available. This beast features as many as ten individual physical cores, expanded support for multiple GPUs and improved overclocking controls. Also, these processors require an entirely different motherboard chipset than the standard i7, because it supports up to half as many pins than a regular Intel Core i7 CPU carries.

This is not just too much, but an overkill for most users. Only the high-end builders that are comfortable spending over $2000 on a new computer will even consider purchasing this particular CPU. And of course, those who work with demanding video and photo editing software. This extreme edition of the regular Intel Core i7 is without a doubt the best choice for complex visual editing or visual effects creation.

Intel i5 vs i7 Prices

As expected, the Intel Core i7 is significantly more expensive than the i5 version. You can purchase the latter for prices starting below $200. However, the Intel Core i7 comes off as quite an expensive choice, starting at no less than $300. Needless to say, that when you will want to install this CPU, you are going to need a compatible motherboard, as well. So, expect to pay at least $400 for both the CPU and the motherboard.

Furthermore, in order to make the best out of this demanding processor, you will have to top your overall expenses with $30 worth of 8 GB of RAM memory and a $200 graphics card.
