Intel Core i7 vs. Core i9: Which Is Proper For You?

In terms of processors, it may be usually laborious to decipher the string of numbers that distinguish them. Usually, although, the upper the quantity, the extra highly effective the chips are. Core i9s are extra highly effective than Core i7s, that are extra highly effective than Core i5s. Easy sufficient.

However on the subject of which you should purchase, it turns into extra advanced. There are some vital variations between them, particularly on the subject of the most recent era.

That will help you resolve which is the fitting CPU for you, we’ve pitted the Intel i7 versus Core i9 to see how a lot you actually get by upgrading.

Must you purchase a Core i7 or i9?

For most individuals, a Core i7 processor needs to be highly effective sufficient. With Intel’s Ninth-generation CPUs, the Core i7-9700Okay has the identical eight cores because the 9900Okay, a frequency that nearly matches it (and infrequently can with slightly overclocking) and solely falls just a few % factors behind in video games and extra limited-thread duties.

It’s the shortage of hyperthreading which most separates them, giving the 9900Okay assist for as much as 16 threads at a time and noticeably improved multithreaded efficiency.


Different Core i9 CPUs just like the older i9-7900X, all the best way up to the super-powered i9-9980XE, broaden on core counts, and supported threads and usually ship higher multi-threaded efficiency. There are some video games which may make the most of the extra threads and sure benchmarks may also profit from the added grunt of these super-expensive chips, however usually, the profit is minimal.

For those who’re seeking to outfit a workstation for rendering, video enhancing, or different intensive duties that may make the most of giant numbers of cores, then a Core i9 is price contemplating. Excessive-end avid gamers could need to go for the 9900Okay or KS if price range is not any concern, however the 9700Okay is considerably cheaper with very shut efficiency. For nearly anybody else, the Core i7 is the higher alternative.

Intel Core i9- 9900K

Probably the most modest of Intel’s present Core i7 CPUs is the Eighth-gen Core i7-8700, which comes with six cores, helps 12 threads, and a most turbo frequency of four.6GHz. There’s additionally a “Okay” model of that very same chip, which has the next base frequency and might turbo as much as four.7GHz. Nonetheless, the principle differentiating issue is that it has an unlocked multiplier, so it may be overclocked extra simply. If that’s not one thing you’re enthusiastic about, the 8700 will carry out the identical out of the field.

For across the identical value because the 8700Okay you may get the Intel Core i7-9700Okay, which lacks hyperthreading assist, so can solely deal with six threads at a time with its six cores. It does, nonetheless, turbo clock as much as four.9GHz, so it’s out of the field efficiency in sure duties is larger.

The Core i9 CPUs are extra highly effective in some methods, however they do value much more for it. The 9900Okay is out there for $485. It provides two cores, hyperthreading assist (as much as 16 threads at a time) and a turbo frequency that may hit 5GHz on a single core, however it’s not considerably extra highly effective. There’s additionally the 9900KF, which is slightly cheaper at $465, and comes with out onboard graphics, and the brand new 9900KS, which affords a assured 5GHz throughout all cores out of the field. It is available in at value of $513.

From there, Intel’s Core i9 CPUs go from costly to pockets destroying. The 10-core i9-9820X prices $770, and the costs go all the best way as much as the $2,000 9980XE. It affords 18 cores and 36 threads, however its inventory frequency maxes out at four.5GHz. These CPUs have been changed in late 2019, nonetheless, with the brand new Cascade Lake sequence. They’re barely quicker and considerably cheaper; by as a lot as half the value of their predecessors.

Core i7 vs. Core i9 in laptops

Intel’s most up-to-date CPU releases have all been cellular choices, from the impressively-capable Ninth-generation Core i7 and Core i9 chips, to the most recent 10nm Ice Lake, 10th-generation CPUs that began transport in August, 2019. The previous begins with the six-core, 12 thread Core i7-9750H, which may enhance as much as four.5GHz, and maxes out with the stupendously highly effective Core i9-9980HK which has a full eight-cores and 16 threads and a most single core turbo velocity of 5.0GHz. These had been the primary cellular processors with eight cores to be present in comparatively thin-and-light laptops — and from the assessments we’ve seen thus far, they’re extremely highly effective in multi-threaded efficiency.

It’s at the moment essentially the most highly effective mainstream cellular processor we’d ever seen, exhibiting up in prime configurations for the brand new Dell XPS 15 and MacBook Professional. Nevertheless it has some new, stiff competitors from the brand new Ice Lake processors. The highest-tier Core i7-1068G7 CPU won’t fairly attain the identical clock speeds (topping out at four.1GHz on a single core) and it solely has 4 cores and eight threads, however it does so for simply 28 watts.

Compared, the large Core i9 CPUs draw as a lot as 45 watts. One Core i7 Ice Lake CPU, the 1060G7, can function with as low a TDP as 9 watts. In addition they take pleasure in rather more succesful, 11th era, Intel Iris Plus graphics.

In a complicated transfer, Intel additionally has 10th-generation Comet Lake cellular processors which might be primarily based on its older, 14nm course of. They’re transport out in quite a few laptops in the direction of the top of 2019, and can are available two and 4 core variants, all with hyperthreading. Their graphics cores will probably be considerably weaker than their Ice Lake counterparts, however clock velocity is perhaps larger, which can make them higher for higher-end gaming laptops.

We don’t know but if we’ll see Core i9 CPUs from Ice Lake or Comet Lake which may problem the ninth-generation for top-tier efficiency, however Intel plans to stay to those lower-powered U-series and Y-series processors to begin off that are restricted to Core i7. 10th-gen H-series processors aren’t due out till early 2020, which is the place we’d get an replace to the Core i9.

The primary cellular Core i9 chip, the 8950HK, didn’t make as massive of a distinction in efficiency as a result of it used six cores identical to the Core i7-8750H. However when it comes right down to a buying choice, you actually solely want a laptop computer with a Core i9 processor should you’re doing one thing like enhancing video or 3D modeling.

What about Core i5 CPUs?

If the value tags and options of the Core i7 and Core i9 CPUs appear slightly overkill for what you’re planning to make use of them for, you’re in luck. Intel has a number of extra inexpensive and modest choices so that you can choose from. They’re usually referred to as Core i5 CPUs, and so they supply many of the efficiency capabilities of the entry-level Core i7 CPUs for even much less.

On the $200-$300 mark you would possibly need to contemplate AMD’s Ryzen CPUs too. They’ve the type of core counts you’d solely usually see with Core i7 and Core i9 CPUs so make for nice multi-threaded workhorses and with the latest 3000-series enhancements to single threaded efficiency, they’re pretty much as good if not even higher at gaming than Intel.
