Picking out a processor when you are out to purchase a laptop for little domestic use does not require too much of research to be done to make a pick. But when the processor determines the outcome of your which translates your efficiency and effectivity, the choice of the best pick for yourself is important.
The only way you can stay ahead in the game which requires the use of technology is by keeping up with the pace of the changes and upgradation in the technology.
Hence, here we are going to simplify the job for you by pitting the two processors- Core i7 and Core i9.
The performing ability of the processor is represented by its name. Previously, the names of the processors were as per the clock speed and later the nomenclature shifted to the ‘Cores’. Core is not to be mistaken for the chip, but it is the processor in itself. Therefore the number of cores present is directly proportional to the number of tasks that can be performed simultaneously.
By this one can simply say that core i9 is a lot more powerful than core i7! Which to quiet an extent is true but the complications arise when you look into the intricacies of the two latest generations.
The frequency tells how much of work can be completed in each cycle. The frequency of the processor is measured in megahertz or gigahertz, and the number that is accompanied by the standard measure is what takes into account the internal clock within the CPU which moves per second. On an average the clock ticks 2.5 billion times in 2.5 gigahertz of CPU.
But, by the use of frequency alone, the performance of the CPU cannot be checked.
Now all the PCs have moved to using cores. Presently almost all the PCs are multi-cored. Each core has the functional capability just as other cores. Each core has a cache of its own. The cores can communicate with other CPU cores as and when needed.
Comparing i9 and i7 can be done only when the Intel architectures are broken down:
- Intel Core series (Coffee Lake)
- Intel Core series X- series processors
Intel Core series- To keep things simple it is but obvious that i9 out performs i7 by the availability of more number of cores, cache and clock. But what makes a notable difference is hyperthreading.
Hyperthreading is a technology that was introduced by Intel to fill up the transitional times that was otherwise being wasted when multiples data is processed. Intel has introduced hyperthreading in i9 processors presently and has made the feature exclusive to i9 while it used to be a feature in previous generation i7 processors.
Intel Core X- Series- other than the regular difference of better cache and core count, the only difference between i9 and i7 can be said to be that i9 has 10 or more cores and i7 has 8 cores.
The most inexpensive and functional processor is Core i7 CPU which is the 8th generation Core i7 series which has six cores and supports a good deal of twelve threads, has a turbo frequency of 4.6GHz. An alternative version of “K” chip which can extend the turbo frequency up to 4.7GHz. Turbo frequency is a feature native to Intel that increases the operating capacity as and when the work gets demanding.
The Core i9 has the feature of hyperthreading which can support up to a whopping 16 threads and also has two extra layers of core, with a turbo frequency of 5GHz for each core. That being said it’s to be noted that it’s not all that powerful to make a radical difference.
But the 10-core i9 9820X has 18 cores to offer with 36 threads and a frequency of 4.5GHz.
The newly introduced Cascade Lake series are priced much lower compared to the other i9 series and also has variants with18 core, a 14 core, a 12 core, and a 10 core processors, along with hyperthreading and turbo core 3.0 technology; which makes it quiet faster and relatively an economical purchase.
Core i9 Vs i7 for laptops
The recent Ice Lake launched by Intel has both i9 and i7 chips that been out in the market since August 2019. i7 has 6 cores with 4.5GHz, while i9 has eight whole cores with 16 threads and a turbo speed of 5GHz. These are the mobile offering made by Intel which can be accommodated in the slimmer and thin laptops are unbelievably fast and powerful.
Before going further deep into the comparison, let us look at the requirements of people from different walks of life:
- The 9-5 office goer
Since the work of an office goer is more to do with the use of basic applications and majorly uses apps like Microsoft Office, there is no need for a superfast processor. A a processor with decent speed like i5 should do the task.
Considering the age of the students and how tech savy the millennials are, the use of a computer or laptop is varied. It can range from studying online, taking online classes, downloading e-books, watching movies, using social network etc. Hence the users can pick either of i5 or i7 series to meet their needs.
A gamer’s system has to multitask a lot! The system doesn’t just have to be good enough to give the best of framerates but also cater to the other needs like chatting both verbal and written, screen recording etc.
Believing that a gamer already has a relatively faster processor and other assisting devices, getting a new processor is just another upgradation for better gaming. The best pick for gaming would be Core i9-9900K it is octa core processor that also supports hyper threading which virtually makes it 16 cored. The processor can also support four-channel DDR4 RAM, has a greater cache, both of which can improve the whole gaming experience. No gamer relies on the integrated graphics, they up their standard by adding a dedicated graphics card. So, it doesn’t matter whether you’re playing the latest games or live-streaming your session, or even playing virtual reality games with a headset, this processor can take care of it all!
- Professional use
A professional user has very specific and core needs. It can range from editing a video, coding, 3D modelling etc. taking all the above into account, a professional user needs the Intel Core i9 7920X. The main reasons to pick Core i7 is it’s the cache and the RAM.
It has an incredibly fast cache that has 19MB of L3. The RAM is a four-channel DDR4 RAM, so theoretically it can add up to 64GB of RAM. It has incredible security system that ensures that all the data doesn’t get corrupted.
- Tech enthusiast
An enthusiast always wants the best of the best and the newest gadgets out there. Unless the enthusiast uses the system for processor intensive tasks, the difference in the system.
Pitting Intel Core i7-8850H & Core i9-8950HK
Both the above chosen processors have 6 cores and 12 threads. Core i9-8950HK has a faster clock speed with a 4.8 GHz while the former has 4.3 GHz. It also has better cache space in comparison to i7-8850H- 9MB while the later has 12MB.
Taking the above factors into account, the performance of the processors are being checked at by setting various checks and benchmarks as per varied uses like:
- Geekbench 4 test- this test checks the overall performance of the processors including the memory. As per the results, i9 performed up to 9.4% faster than i7.
- Handbreak Benchmark test (Video Transcoding)- This checks the amount of time it takes to convert a clip of 27GB, running12-minute and 30-second long in 4K video in to 1080p. The i9 was up to 6.4% faster than i7.
- Excel Test- An excel test that undertakes a task of matching 65,000 names with their respective a1ddresses. i9 performed the test better than i7 by 6.4%.
- Rise of the Tomb Raider- this is a gaming check to see the number of frames that are shown each second. And surprisingly, the i7 outperformed the benchmark by producing 71 frames a second instead of 60! Although i9 displayed 80 frames per second thereby outshining i7 by 10.1%.
- Hitman- this game is used to check the visual performance. i7 did surpass the average by delivering 95 frames per second but i9 outperformed it by delivering 107 frames a second.
- Grand Theft Auto V- the performance of the two processors were almost not visible. The difference between the performances of the two were merely of 0.5%, which is a negligible margin.
Final word, which one to get?
The Core i9 turns out to be quite the beast, as it dominated every test laid before it. And what makes it impressive is that the chip overclocks with the CPU there by surpassing the Core i7 by 17% on bare performance and nearly 10% in video-editing performance. However, there was almost invisible difference in gaming frame rates, especially between the standard Core i9 and overclocking.
If the work being done using the system related to an industry in which the tasks regularly work on 3D modeling or video editing or other highly taxing programs then spending this kind of money on a Core i9 can be worth it as it will bring a dramatic improvement in such conditional your livelihood. However, if the use of the system is that of a casual user or even a serious gamer, it can be recommended that you save the money for upgrading the graphics card or storage or for a beautiful and vivid 4K display.
