ASUS ROG G703 GAMING LAPTOP – Desktop Replacement Laptop?

ASUS ROG G703 Gaming Laptop - Gadget Boulevard

The ASUS ROG G703 is a laptop that can replace my desktop PC? That would be great for me personally.

But is there such a thing? Surely you can cram the best processor and graphics card into a laptop. But it would weigh a ton with all the needed parts to cool the system.

So did ASUS finally found the answer for getting the much needed performance that is comparable to a desktop PC without the weight issues?

Let’s find out if on paper the ASUS ROG G703 is a worthy desktop replacement laptop.

The ASUS ROG G703 is a beast?

Yup, most likely. I remember that the AMD powered version of the Acer Predator Helios 500 is also a beast of a laptop. Weighing at four kilograms and having an AMD Ryzen desktop processor inside makes it a powerful beast.

But that’s not all, it’s graphics card is an AMD Radeon Vega 56!

So how does this ASUS ROG G703 compare to the Helios 500 when it weighs 4.4 kilograms!

Overclocked Intel Core i9-8950HK

Compared to the Helios 500 the G703 does not use a desktop processor. Rather it has the 9th Gen i9-8950HK processor which is the fastest of all Intel mobile processor lineup.

And ASUS wasn’t content with that, they’ve overclocked it to 4.8 Ghz on all cores out-of-the-box.

Though the i9-8950HK is only a 6-core 12-thread processor as compared to the Ryzen 7 that the Acer Helios 500 has. Intel’s overall IPC performance versus AMD is still way ahead making the i9-8950HK much faster than the Ryzen 7.

Core count wouldn’t matter as much as most popular games wouldn’t utilize more than two or four cores when gaming. But since this is a desktop replacement laptop, it is good to note that when it comes to softwares that utilize more cores the G703 will not be a slouch.

With a fast processor you’ll need fast memory. As with any other Intel processor the fastest RAM it could use are DDR4-2666 Mhz modules. Not a fault by ASUS but this is the maximum frequency that the i9-8950HK can use.

The G703 will have dual channel memory modules and is upgradeable up to 64GB.

GeForce RTX 2080 – Max-Q or not?

According to the tech specs on the ASUS website the G703 has an Nvidia GeForce RTX 2080 with 8GB of GDDR6 RAM.

Nothing written on their website implies that it is a Max-Q version so we’ll assume that it’s not.

So if this is the case then performance of the G703 would be at par with any desktop with an RTX 2080. Granted that they paired it also with a 6-core 12-threaded processor.

That said, the G703 will have an edge over other gaming laptops that use the Max-Q design variant of the RTX 2080. But this is at the cost of weight and price as this would need an elaborate cooling solution.

Heavy-duty cooling

Cooling the ASUS ROG G703 gaming laptop ASUS decided on a heavy-duty approach. Designing from the ground up the chassis of the laptop is optimized for airflow. While most gaming laptops will have two exhaust outlets the G703 will have four.

Along with these four exhaust outlets are four separate fin-stacks with 0.1mm thermal fins providing larger surface area for heat dissipation. While two high performance 12V fans deliver massive airflow to cool the fin stacks keeping the system stable.

Each fin-stack will have two or three heat-pipes running through the CPU, GPU, and other heat generating components to keep the system cool.

ASUS also incorporated an anti-dust cooling system within the fan modules. This ensures that dust particles are blown out of the chassis rather than clogging up on the fin-stacks.

Other fast features of the ASUS ROG G703

While we’ve covered most of the major parts let’s move on to the other features of the G703 that makes it the desktop replacement laptop.

While screen size does matter for some this is still a laptop so having a 17.3 inch screen is not surprising. But having a 144Hz refresh rate, a 3ms response time, and 100% sRGB rating is something you’ll only get at higher end monitors.

And by the way, this is G-Sync enabled if it matters to you.

For storage, the G703 is not lacking, specially in performance as the G703 will use the ASUS HyperDrive Extreme.

ASUS advertises their HyperDrive Extreme as capable of reaching 8700 MB/s. But take this with a grain of salt as ASUS didn’t mention if it’s read speed or write speed.

To reach the advertised speeds ASUS will use a Samsung PM981 or Samsung SM961 and two Intel 760p SSDs for a RAID 0 setup comprising of three NVMe PCIe 3.0 x4 SSDs.

Actual performance will vary depending on the configuration of the G703 available.

Other fast features are the 2.5 gigabit Ethernet and gigabit Wifi.

RGB keyboard and lit ROG logo

The G703 wouldn’t be top-of-the-line if it’s not RGB, am I right?

For the G703 RGB lighting will be controlled using the ASUS Aura Sync technology which allows you to customized lighting effects. And not just for your laptop, it also allows you to synchronize your RGB effects with other Aura Sync supported peripherals.

So if you have an Aura Sync capable mouse, keyboard, or headphones you can control their RGB effects and sync them with the G703.

Speaking of RGB, the biggest RGB lighted part of the laptop will be the keyboard. The keyboard that the G703 have is not your ordinary chiclet keyboard but rather an improved version of it.

ASUS calls it ROG Overstroke technology. The main difference is that actuation for each key is 62 gram-force and the firing point has been adjusted to half the distance of its 2.5mm travel distance.

Can this replace your desktop PC?

We’ve covered enough of the ASUS ROG G703 and I think it can replace your desktop PC. But let’s check pricing of the G703.

The top-spec G703 will fetch you around $4,000 US.
