Core i7 vs. Core i9: Which is the best high-end laptop CPU?

intel core i9

Once you’re looking for a high-end gaming laptop computer, one basic alternative is whether or not to purchase a mannequin with a Core i7 or a Core i9 CPU. The Core i7 CPU is highly effective, however the Core i9 is meant to be the topmost performer, the acute machine—often with an upcharge to match.

Once you’re targeted on the CPU it’s concerning the efficiency, and two main elements have an effect on that: the megahertz or clock velocity the CPU runs at, and the quantity of compute cores it has. In laptops, yet another crucial constraint is the cooling, which might throw a monkey wrench into all of it. 

We’ll assist you resolve which laptop computer CPU is finest for you, with details about the Core i7 and Core i9 within the final three CPU generations from Intel, and which is probably going the higher alternative on your laptop computer. Beginning with the most recent and dealing our manner again…

11th Era: Core i9 vs. Core i7

Intel’s 11th-generation Tiger Lake H marks one main milestone: Intel lastly strikes from the identical 14nm course of formulation it’s used for its H-class CPUs since 2015 to its most superior 10nm SuperFin course of. We had been ready years for this alteration.

Now that Intel lastly has a 10nm efficiency chip to brag about, a slew of Tiger Lake H laptops have been introduced. Some have already trickled out into shops, together with the skinny, gentle, and surprisingly inexpensive Acer Predator Triton 300 SE we have already reviewed.

You may see the lineup under. All the Tiger Lake H chips are Eight-core CPUs, one other change from prior generations, the place core counts helped outline the efficiency expectations from completely different chips in the identical household.

All the 11th-generation Intel Tiger Lake H laptop computer CPUs use a 10nm manufacturing course of and have Eight cores. 

The clock variations are sparse, too. The Core i7-11800H tops out at four.6GHz, whereas the Core i9-11980HK can hit 5GHz, about an Eight.6-percent enhance in clock speeds. That’s not unhealthy, however when you think about that each are Eight-core CPUs, Core i9 isn’t compelling for many customers.

There’s yet another case to be made for Core i9, although. The Core i9-11980HK does provide the non-compulsory thermal design energy (TDP) of 65 watts. That increased TDP is accessible solely on the top-end Core i9, which suggests in a laptop computer that may deal with the ability necessities and cooling, it could certainly provide larger sustained increased clock speeds than a Core i7 model.

Such a laptop computer would probably be thicker and bigger, although. So in case you’re taking a look at two skinny laptops, one with a Core i9 and one with a Core i7, the thermal and energy headroom is probably going not going to make the distinction value it.

11th-gen winner: For many customers, Core i7

10th Era: Core i9 vs. Core i7

With the 10th technology Comet Lake H family, Intel remained stuck at 14nm. The trick it pulled out this time was to offer 8-core CPUs in its Core i7 as well as in its Core i9 CPUs, giving users greater performance potential without having to pay for the top-dollar chip.

Even though 11th-generation laptops are starting to come out, you can still find some good products with 10th-generation CPUs, including the MSI GE76 gaming laptop we reviewed earlier this year. With its fast CPU and blistering 155-watt GPU, this laptop lives loud and proud. It even wears its RGB right there across the front edge. 

The Ninth-gen Core i7 and Core i9 chips provide the identical variety of cores and shut clock speeds, that means there’s little distinction for many customers.

As with the 11th-gen chips, the shut cores and clock speeds imply the variations between Core i7 and Core i9 are minimal for many customers. With a most enhance clock of 5.3GHz for the Core i9-10980HK and 5GHz for the Core i7-10870H the distinction between the 2 chips is about 6 p.c on paper. Until it’s good to push your PC to the max, it is probably not value the additional money for the 10th-gen Core i9.

Ninth Era: Core i9 vs. Core i7

With the Ninth technology of Espresso Lake Refresh laptop computer H-class CPUs, Intel was nonetheless  stretching the 14nm course of so far as it might go. A Core i9 gave you increased clocks (as much as a whopping 5GHz) and likewise denoted Eight CPU cores. 

Positive, this chip got here out two years in the past, however you’ll be able to nonetheless discover it in good gaming laptops together with the XPG Xenia 15, which Intel helped design. It is skinny, gentle, and quick, and it sports activities an Nvidia RTX GPU as nicely.

You may see the highest H-class Core i7 and Core i9 chips under.

Core i9's clock speed is slightly fasterIntel

Within the Ninth technology of H-class CPUs, Core i9 meant two further CPU cores over the Core i7.

The distinction between the Eight-core, four.8GHz Core i9-9880HK and four.6GHz 6-core Core i7-9850H is about four p.c in clock speeds, a distinction few individuals would be capable of inform distinction in precise use. Each of these CPUs had been widespread in enterprise laptops.

Most customers laptops noticed a alternative of the Eight-core 5GHz Core i9-9980HK and the 6-core four.5GHz Core i7-9750H. That added as much as an 11-percent clock distinction between the CPUs, which is demonstrably quicker and measurable, although we’d once more argue most couldn’t really feel the distinction.

The distinction in core rely, nonetheless, would usually yield way more profit in multi-threaded purposes. We’ve recorded scores in an older XPS 15 with a Core i9-9980HK as much as 42 p.c quicker within the 3D modelling take a look at Cinebench R20 than a gaming laptop computer configured with a Core i7-9750H. In a heavier workload that heats up the Eight-core Core i9, the efficiency hole shrinks to only 7 p.c. Clearly, the laptop computer’s design issues right here quite a bit. You may no less than make the case for Eight cores versus 6 cores in some situations.
