System Performance

The ASUS ROG Phone II’s system performance is naturally of double interest: First of all, it’s actually the first Snapdragon 855+ based phone we’ve gotten to benchmark here at AnandTech. We don’t have too high expectations over the meagre clock frequency increase of the Prime core from 2.84 to 2.96GHz, but possibly ASUS’ tuning and the X Mode might be able to differentiate performance a bit more above what we see in other Snapdragon 855 devices out there.

We’re testing the phone in both its default out-of-the-box mode, as well as the X Mode:

PCMark Work 2.0 - Web Browsing 2.0

In the PCMark Web Browsing test, we already see quite a bit difference between the two operating modes. The default mode is quite conservative as is matching the lowest scores that we’ve seen of other Snapdragon 855 phones.

X Mode on the other hand seems to increase the performance here to be more equal in behaviour to that of the Galaxy S10 – the best performing S855 device in this test. It’s to be noted that this test is also very sensitive to various DVFS shenanigans – for example the score might go up quite dramatically if the vendor decides to peg the frequencies to a higher minimum frequency. X Mode in this regard doesn’t behave this way and still properly scales along the full frequency curve – albeit doing it in a much more aggressive manner.

PCMark Work 2.0 - Video Editing PCMark Work 2.0 - Writing 2.0

The writing sub-test is one of the most representative of overall performance of a phone. In the default mode the ROG Phone II performs well and is amongst the top S855 devices. Turning on X Mode makes the RP2 stand out amongst its competitors.

PCMark Work 2.0 - Photo Editing 2.0

In the Photo editing test, the RP2 performs the best in both its modes. The higher scores here can also be attributed to the higher GPU frequency of the S855+ SoC in the device.

Overall, the RP2 lands in as one of the most performing phones on the market, and the X Mode in particular puts it ahead by a large margin. It would come at a cost of power efficiency, but with a 6000mAh battery, the RP2 shouldn’t worry too much about that.

Speedometer 2.0 - OS WebView

In the web browsing benchmarks, the RP2 oddly falls a bit behind in Speedometer when enabling X Mode. Given that the test is a continuous workload with high load, the different scaling modes should indeed not affect it, but it’s still a bit odd to see the minor regression.

WebXPRT 3 - OS WebView

In WebXPRT 3, we’re seeing a more expected scaling between the two modes. The ROG Phone II here is able to take almost the highest scores amongst Android devices, just falling short of the Huawei P30.

    Ian doesn't mention a weakness to kryptonite and I didn't see it wearing a cape so at this point the answer is unclear. Reply

    Pretty amazing device. Glad to see someone pushing boundaries in some ways. Reply

    If they want to make a "gaming phone" why not add some physical controls like the Nintendo Switch? Reply

    This Asus phone has physical control like switch, but you have to buy them separate. Reply

    I just realized I can't edit my comment so... at least include a controller accessory that attaches to it directly and acts as a cover as well Reply

    As a ROG2 owner, happy to see you reviewed this 'phone'.

    I didn't buy this for gaming.

    For me, the purchasing decision lay with the battery size, the front facing speakers (great for GPS in the rental car to be heard), the dual sim & dual 4G (it was 4G+3G on S8+), headphone jack, and finally, lack-of curved screen - which I shall never part money for again.

    Mine is the 128GB/8G version, it was too cheap to ignore.

    Oddly, my Slingshot Extreme Physics score is 4,837 vs your 4,541 (ran Sep 27, 2019 22:08, check it online), which would easily top your chart. Glitch in the matrix? Dunno.

    I have a Chinese ROM, (and it was updated this morning). Whilst its rare to see the fact that it is a Chinese ROM, you do see it from time to time, in some screens, despite being set to English.

    I had it on launch-day. There was no 'sim card manager' in the s/w!?! I was unable to change data sim, choose a sim with which to respond with sms etc without popping a sim out to force a pop-up. This has now been corrected.

    Additionally, I initally never saw my dual sims report 4G & 4G. This has also been somewhat corrected, but as I sit in the UAE now, I am 3G & 4G. There is no way to force 4G & 4G from the menus. It will either do it (not often) or not, you have no choice. You can however set 3G & 3G, or 2G & 3G etc (but why). On the plus side, whichever sim is chosen for data, with take over the 4G role. So something here still very much requires attention.

    I miss the wireless charging, but the battery-size somewhat negates that. It was nice with the Samsung to drop it on the pad, everytime I sat down at the desk, and know it would be further topped-up when I picked it up to walk away again. And it was nice having the water protection as well, (considering we have a pool), as I have drowned a new handset before...Hmm, maybe I should back this thing up.

    What did you get to cover the back? Reply

    It shipped with a clear plastic hard case. But I changed it for a clear rubberised one. Reply
