Asus G750JX: Performance

With its powerhouse specifications, it didn’t surprise us to find day-to-day usage of the G750JX a joy, once we’d got used to its substantial bulk at least. Programs load quickly, and performance is generally swift, although our model shipped without a solid state drive leaving boot up times a little on the disappointing side (45 seconds from cold and 51 from a restart). This can be upgraded in various ways, and does include the option for a hybrid drive with SSD storage space of up to 256GB.

Our standard benchmarks made for interesting reading. In PC Mark 7, it scored 3,909. A solid score, but a way behind our leaders: the Gigabyte U2442V gaming Ultrabook (5,066) and the Lenovo Carbon X1 Touch business laptop (5,056). It was however ahead of high end business laptops like the Toshiba Satellite P50t-A-10U (3,094) and HP Envy Touchsmart 15 (3,573). However, the score is a tad misleading as its largely down to the lack of an SSD, something PC Mark 7 places a high value on.

Geekbench 3, our cross-platform benchmark, shows the G750JX has all the performance it needs for games. Here the G750JX scored an impressive 11,797, putting it well ahead of the aforementioned U2442V (3,195) and second in our charts overall just behind the dauntingly powerful 27-inch 2013 iMac (14,462): impressive stuff.

Gaming is where it really counts in a gaming laptop of course, and unsurprisingly we weren’t let down. Since we started using 3DMark, we’ve not seen it break the six-digits barrier in its scores, but we’ve seen it now. In the entry level Ice Storm tests, the G750JX managed a whopping score of 107,738, and barely lowered when moving into the Ice Storm Extreme version, clocking 89,413. Suffice it to say both of these were unmatched in our previous benchmarks, with our previous winner on the low-end tests, the Toshiba Satellite C55-A-12U managing less than half (45,485 in Ice Storm and 29,177 in the Extreme variant.)

The impressive results continued into the Cloudgate tests, where the machine racked up 14,779 - this sounds like a big drop off, but considering our previous best was 7,078 (HP Envy Touchsmart), that’s not to be sneezed at. We were so impressed that we put 3DMark on the previously untouched Firestorm setting, aimed at high-end gaming PCs. Here, finally, it began to struggle, clocking up just 3,133. As mentioned, we have nothing to compare that to at the moment, but it’ll be useful the next time a gaming laptop shows up.

Finally, in order to compare it to the 27-inch iMac, we ran the Unigine Heaven benchmark, where it racked up framerates of 29fps in the basic test and 17.3fps in the extreme one. While these are slower than the iMac (which clocked 27.8 in the extreme test) these are still impressive scores in a laptop, and should impress most gamers given the complexity of the test (as mentioned in the iMac review it contains some really intense detail with 8x anti-aliasing, maximum level of tessellation and volumetric shadows.)

So how did it cope in the real world, outside of benchmarks? We loaded up Crysis 2 to put it through its paces. It ran beautifully smoothly at 1,920 x 1,080 resolution with Ultra detail. Tellingly, if you pull out the charger while playing, the framerate plummets and the game becomes a slideshow, so there’s clearly a lot of GPU efficiency saving when on battery.

Asus G750JX - Heat & Noise

In day-to-day use, the G750JX is impressively quiet. You can definitely hear the fans, but its a consistent low hum, rather than the jet-engine that some laptops provide. The 17.3-inch frame does a good job of dissipating the heat as well, and it’s pretty much cold to the touch in web browsing and word processing.

Even when under heavy strain in our gaming tests, the fan made barely any more noise - and even if it were to, in gaming conditions it would most likely me drowned out by in-game sound anyway. The temperature was equally consistent. Colour us impressed.

Asus G750JX: Battery Life

We weren’t quite sure what to expect from the G750JX’s battery: on one hand it’s a high-end gaming laptop, with a massive screen so likely to be power hungry, but on the other, there’s plenty of bulk for a heavy battery.

In the end, the specifications won out. In our standard battery test at 40% screen brightness, running through video, word processing and web browsing tasks, the machine gave us three hours and 20 minutes usage before needing to be plugged in. Okay, but nothing spectacular.

From a 30-minute charge, the battery regained 26% of its capacity. Again, pretty standard, and well below the best we’ve seen (take a bow Lenovo: the Thinkpad Carbon X1 Touch manages 77%), and equates to around 52 minutes of real world usage.

Of course, given the weight of the machine, it’s unlikely you’ll be away from a plug for too long in any case, so this shouldn't be an issue for most users.

Interesting piece.

I've just bought a PCSpecialist laptop which was about £250 more and came with a 240GB SSD, 1TB data drive, 4GB ATI 8970 and 3 year on site warranty.

It shows you how good a value they are, but the downside is the Clevo chassis isn't anywhere near as resolved as the Asus one we see here.

Hello...I have also been considering PCSpecialist for a new gaming/performance laptop, particularly the much higher end specs achievable that way for a similar price (as you've mentioned). Can you explain in more detail what you mean by "the Clevo chassis isn't anywhere near as resolved"? Also, previous Asus gaming laptops were marvellous at self cooling....what is the cooling/noise like with your pcspecialist one?

Hi Nicholas Heitz - I'm more than happy to answer your questions :)

I've just had mine back from an RMA and it's about to go back again sadly. I'll answer your initial questions first and then explain the woes I've had.

First the Clevo chassis - yes, it has aluminium panels but it's wrapped around a plastic chassis. It seems to have been included to simply check the box for a "premium laptop" - ie, it must have metal touch points.

The aluminium is textured/grained and is a finger print magnet like no other finish I've encountered - it's tricky to clean as well, due the grain nature. They also use this finish on the trackpad - this causes a problem where the grain actually leads your finger some times, it's not a frictionless experience at all.

I also think it's cheaply constructed, it doesn't feel that sturdy and it has no ergonomics to speak of!!

With regard to the cooling - since it has come back from the first RMA with a BIOS update it has been significantly quieter and better in general, which is awesome. It's wasn't too loud before, you could hear it over a movie though (even if you were watching it on a TV over HDMI), now you can't - this is good.

Now I'll mention the issues I've had - the wrong image was installed when I received it so it has clashing drivers. I had to format it to solve that, then I updated to Windows 8.1 and that failed to work due to a Clevo driver so I had to format again. Then I noticed there were tonnes of partitions on my SSD which I couldn't delete so I formatted again.

I then Windows 8 equivalents of BSOD's on every Cold Start so it went back for an RMA - they found the BIOS update solved all the BSOD issues but it came back with the keyboard backlight not working once it had booted in to Windows. This was a result of the BIOS update and the keyboard backlight software not liking it - I was told to uninstall then reisntall it - it crashed during the reinstall. They've told me to reformat and I've flat out refused to (as it takes a good couple of hours each time) - they are going to do it for me.

I actually want a refund but none is forthcoming - if it was me, and you don't need an optical drive, I'd go for an MSI GS70 Stealth.

I apologise is that's rambling, I haven't re-read it as I'm tight on time, but I hope it helps :)

Ed's - do you happen to know which model variant comes with the SSD drive?

I've had my Asus G750 JX for 2 weeks now and it is amazing, i got one of the top specs as it has x2 120gb SSD and x2 500Gb HDD also it has a blueray writer & 16Gb memory and of course the GTX770 i think i got it for a great price, i paid $2172 Australian Dollars. it was in the shop for $3000 and had the price dropped, it also came with assassins creed black-flag a head set and a bag which doesn't it fit, i tried getting a free mouse as well but i think i was asking a bit too much :) ill be buying a Razer Naga Molten today when i finish work, as i gave my last 1 away when i left the UK for Australia back in october. Now im going back the UK i think with the exchange rate being currently terrible for converting my Dollars to pounds i got my self a bargain, i have currently played, Titanfall Beta, Dayz Alpha, Diablo 3, Company of Heroes 2, Civ 5 and a few other low requirements games like Dota 2 and hearthstone. the setting have all been on high or ultra the laptop handles this with ease, it is almost silent when gaming i have not noticed it, also watching movies you never hear the fans. the thing that impresses me most is the boot time, from off to desktop an loading my programs it is about 8 seconds, it is amazing. it is like the switch from Dial up 56k to broad band i recommend booting from a SSD to everyone. The laptop it self is solidly built and a bit heavy but you can still pick it up with one hand, the keyboard is great the back-light on it is perfect, the track pad is pretty massive even though i always use a mouse, if i had to give this laptop any bad points the only one i can think of is possibly the screen, the colors looked a bit dim to me, but my last pc i had a Asus 125Hz 3D monitor so i imagine anything is going to look not as vibrant as this. i would never buy a laptop to game on usually, but i was forced to as i didnt want to buy a desktop then have to transport it back to the UK when i go home. I can never justify the price of a gaming laptop compared to what i would get from a PC for the same price, but considering i got this for a decent price and my situation it doesn't bother me. it is also great being able to play in bed or on the couch or take my computer with me where ever i go. if you are wanting a high performance laptop which eats up games no problem this is the one, i am so happy with my purchase this laptop is recommended 10/10 especially as the prices will start to come down over the next few months. its still good for all the games i mentioned above, some being next gen games also :)

Had this unit in commission for 3 years 3 months so far. Still purrs and is still gorgeous. Won't ever regret it.. sad the new models have changed colour.. Black has always been my favourite, especially as a screen bezel. Makes the screen almost look like it's floating with its black boarder.. minimal distractions.
