GPU Performance & Power
We also finished up our GPU testing for the Galaxy S20 Ultra, and are able to showcase the Snapdragon 865’s true power efficiency as well as long-term performance for the first time.
The new Adreno 650 iGPU is a continuation of the architecture that has powered Qualcomm’s last two generations of SoCs. The company is advertising a 25% boost in performance, which we were able to verify in our performance preview of the SoC. What wasn’t very clear back then was the power efficiency of the new chip – again, our figures on the QRD865 weren’t very accurate – so testing out the new chip on an actual commercial device will be a much more representative measurement.
This is also the first time we’re able to showcase the sustained performance figures of the new generation SoC. Qualcomm had put a lot of emphasis on this aspect of the new chip, claiming it’s able to throttle a lot less than some other competing devices in the market. We hadn’t had the time to test this on the QRD865, so the S20 Ultra here will be the first device of 2020 going through this test. As a reminder, sustained performance not only is linked to the power consumption of the SoC, but also the thermal dissipation capabilities of the phone that it’s employed in, as well as the thermal limits imposed by the vendor.
Starting off with the 3DMark Physics test, the new chip behaves fantastically, and even manages to perform better than the QRD865. The new Cortex-A77 cores are doing extremely well, and most interestingly, the sustained performance showcased by the unit is also excellent.
The graphics test of 3DMark is more GPU bound – and here again it showcased no throttling. This was a bit odd in the context that I did see more significant throttling in GFXBench…
In the Aztec High test, peak performance is identical to what we’ve seen on the QRD865, and sustained performance after a while throttles down by 25%. Although it’s a good showcase, the new Galaxy S20 Ultra here doesn’t fare any better than some of the best Snapdragon 855 devices out there, as well as lagging behind Apple’s iPhones.

Galaxy 10+ (Exynos 9820) | 8LPP | 15.59 | 4.80 | 3.24 fps/W |
Doing power measurements on the S20U, we see quite better figures than experienced on the QRD865. Thus, the Snapdragon 865 moves up in the efficiency scoreboard, inching closer to Apple’s A-series chipsets.
What’s interesting to see here is the absolute power figure itself coming in a little under 4W. This is an excellent improvement and reduction compared to the Snapdragon 855 last year, and it means heat generation should be a lot more in check compared to previous generation flagships.

The Aztec Normal test also shows excellent absolute peak power figures, and peak performance is where it’s expected to be at. Meanwhile, throttling on the S20 Ultra is again at around -25% of peak performance for sustained scenarios.

In Manhattan 3.1, things are also looking better for the Snapdragon 865. The improved power figures do have it now able to leap the A12 in power efficiency. The sustained performance comes in at 73% of peak performance in our testing conditions.

Finally, in T-Rex, we’re again seeing a healthy boost in efficiency compared to previous figures, but in terms of sustained performance, the S865 is still largely behind the A13 chips.
Besides the improved power efficiency numbers, we’ve now measured on the Galaxy S20 Ultra, the one thing that I really liked about the new device’s behavior is its thermal behavior. The phone wouldn’t exceed 41-42°C peak skin temperature, remaining only relatively lukewarm no matter the kind of workload you’d throw at it. This is some excellent thermal management and I appreciate this a lot more than having higher performance that leads to the phone getting uncomfortably hot. Samsung deserves some praise here.
Fantastic Performance; Stay Tuned For The Full Review
When it comes to performance, the Galaxy S20 Ultra has so far been an immensely impressive device, easily being the single fastest, most responsive, and most fluid phone I’ve had the pleasure to use, quite far ahead of any second contender. The combination of a 120Hz screen with the new Snapdragon 865 is a match made in heaven, and people prioritizing this aspect of a phone will seemingly not be disappointed in the S20 line-up.
There’s still a lot of work to do until we get the full review finished, notably still waiting on the Exynos variants of the devices. One aspect that I want to make note of right now is that there’s been some concerns in regards to the battery life aspect of the new 120Hz mode of the phones, and I can confirm that in this setting the S20 Ultra showcases worse battery life than the S10+ (-10% in our web test), even though the new unit has a more efficient SoC as well as a 21% bigger battery. Samsung’s implementation of the 120Hz mode comes at quite a large power hit that’s very disappointing in how it behaves, and the device in general seems not quite as efficient even at 60Hz.
I’ll be posting a separate battery preview once I get more battery testing numbers together, and of course we’ll have a full feature review out once all the thorough testing is completed.

As far as I remember Samsung's top Snapdragon smartphones were always worst in GFXBench.Tigran - Friday, March 13, 2020 - link
At least when it's about sustained performance.NICOXIS - Friday, March 13, 2020 - link
I saw the tear down on Jerry Rig Everything youtube channel and I was a bit underwhelmed by the cooling system, maybe that's why sustained speeds are not so great?dianajmclean6 - Monday, March 23, 2020 - link
Six months ago I lost my job and after that I was fortunate enough to stumble upon a great website which literally saved me• I started working for them online and in a short time after I've started averaging 15k a month••• icash68.coMLuckky26 - Tuesday, April 7, 2020 - link
is that why now they've started launching phones with Mediatek chipsets, lolTigran - Friday, March 13, 2020 - link
1) Why iPhone 11 Pro Max's performance in 3DMark Physics is worse than iPhone XS's?2) Do you agree that 3DMark is more RAM bound than GFXBench - and that's why iPhones perform worse than SD-smartphones with much RAM?

1) A13 runs hotter, hence more throttling2) No. It's more compute bound, probably some shader combination on which Adreno does better.

2) Then why Galaxy Note 9 (6 GB) outperforms Galaxy S9 (4 GB), both E9810?Physics: 2227 vs 1413
Graphics: 3639 vs 2179

Because the Note9 is a big phone and the S9 is a smaller phone. The peak performance of those two units is identical, the sustained performance is determined by thermals and power.Tigran - Friday, March 13, 2020 - link
Agree. Thanks! Just wonder were I've read about 3DMark being RAM bound...
