GPU Performance

Gaming performance of the ZenFone 7 Pro is also very interesting as it represents a contrasting data-point from the same vendor which also offers a gaming-focused phone such as the ROG Phone III. Both phones also feature the higher performance binned Snapdragon 865+. In the ROG Phone III review we saw somewhat mixed results from the new SoC, so let’s see how the ZenFone fares:

Basemark GPU 1.2 - Medium 1440p - Off-Screen / Blit

Starting off with Basemark GPU, the ZenFone 7 Pro performs quite excellently in terms of its sustained performance figures, with only a few fps of throttling after prolonged periods.

I’ve noted that the phone’s peak skin temperature reached 44°C, which is still reasonable. In essence, it reaches about the same thermal levels as the ROG Phone III when that phone is set to its “Level 2 X-Mode”.

GFXBench Aztec Ruins - High - Vulkan/Metal - Off-screen GFXBench Aztec Ruins - Normal - Vulkan/Metal - Off-screen GFXBench Manhattan 3.1 Off-screen GFXBench T-Rex 2.7 Off-screen

The rest of the GFXBench tests all showcased similar peak and sustained performance figures, strongly favouring the ZenFone 7 Pro.

Frankly speaking this is both a win for ASUS as the ZenFone 7 Pro performs very well, and sort of a self-goal, given that it essentially invalidates performance advantage aspect of the ROG Phone III.

As to why there’s such a stark difference between the two phones, I’m not too sure, however the two devices have quite different motherboard layouts. The ROG Phone III has the SoC placed on a rather narrow motherboard to the side of the phone near the accessory USB-C ports, whilst the ZenFone 7 has it located on a bigger PCB that covers the top part of the phone underneath the cameras. It’s possible that this simple location change allows for better heat dissipation on the ZenFone 7 Pro as the SoC is more centrally located inside the phone, thus making usage of more of the screen as a dissipation area.

    Seriously, doing away with the headphone jack in exchange for 5G. Might as well go with Samsung

    Yeah they say 5G antennas are small, sometimes they omit the fact that you need more than a dozen of them.
  • melgross - Tuesday, September 1, 2020 - link

    You need from three to five, depending on whether you’re using sub mm bands or not, not dozens.

    It's 100% b.s LG V60 and Sony Xperia Mark II both of them are 5G and LG even has full U.S band support with mmWave technology as well and has a superior Audio performance from the standalone RFI shielded high end ESS9219 DAC chipset (ESS9218P was being featured in LG phones from V30 and up) and both of them have IP68 rating along with Qi charging too. The fact that Note 20 gets a full blown Silo for the S-Pen makes so fucking ground for these lying bastards. Removing jack is saving pennies and forcing them to buy accessories which also die out due to the Li-Ion technology.

    Can anyone describe how to understand the ∆E ITP and ∆E ITP LC value?

    I did use ∆E 2000 with Gamma 2.2 for long time, but even searching in google, the data just saying about Rec.2100, EOTF, PQ, HLG and ITU-R....

    I knew ∆E ITP is a part of Rec.2100 HDR...but, the info I really want to know is the relationship between ∆E ITP (LC) and real world.

    ∆E 2000 < 1:Great and almost perfect
    ∆E 2000 < 2:so hard to see the difference and it's good enough for professional users
    ∆E 2000 < 3:good for general users

    ∆E 2000 < 5:ok for general users but still has noticebal color difference
    ∆E 2000 > 7:esay to see the color difference

    Can ∆E ITP and ∆E ITP LC use those standards (0 ~ 1 ~ 2 ~ 3 ~ 5 ~ 7 ~)?
  • Andrei Frumusanu - Tuesday, September 1, 2020 - link

    dE ITP is a new standard that takes into account more modern reproduction formats such as HDR. Generally ITP is a little more sensitive than the 2000 standard to colour deviations:

    dE ITP LC as I use it in the new reviews is simply a luminance compensated value, meaning that the error value ignores the luminance error and only looks at hue and chromacity. This makes sense for example in this review here as the ZenFone is targeting a 2.4 gamma by default, however our measurements are against a 2.2 gamma target. So the dE LC values are always going to be lower since it ignoers that part of the colour inaccuracy.

    Under dE ITP of 1 it's imperceptible, under 3 it becomes acceptable when not viewed next to each other, and over 10 means it's horribly wrong.

    Thank you @Andrei, the reply is really helpful!!!
    Now I can read the Calman's color calibration charts and info well based on that very useful knowledge, and easy to judge which device can provide great display quality.

    Two more things I was wondering in this article:
    1. The devices that Anandtech had reviewed such as Mate 20, iPhone XR, Xperia 1 even Surface Pro or XPS13, will get the updated display quality review based on the new delta ITP (LC) standard?
    2. ASUS ZenFone 7 Series has a telephoto camera that has very similar spec to HUAWEI and Honor devices' (OV8856, 1/4.4", 1 um, F2.2, 80 mm{, OIS}, with terrible PDAF). It brings 3X Optical Zoom to ASUS smartphone first time and I'm expecting the 3X OZ camera can shows on ZenFone 7 Pro's review. This will be interesting if we have a comparison between ZF7P, 1+7P, M30P, P30 those who having a 3X OZ there any opportunity to see this kind of comparison?

    in the end, I really thank to AnandTech's great quality reviews!!!

    "This is something that ASUS actively acknowledges as being a deliberate design choice so that that they could fit in more components and a larger battery"

    Did they forget about the headphone jack?
  • drexnx - Tuesday, September 1, 2020 - link

    >made phone huge for more components
    oh yeah we couldn't throw the 3.5mm jack in there, not enough room. The 5 gees, you know, they take up too much space.
  • Hamm Burger - Tuesday, September 1, 2020 - link

    I thought that the unexpectedly low battery life might be because this phone did mm-wave 5G. Bit no: having dug up the specs, the highest 5G frequency band it can handle is 3.3–4.2GHz.
