Samsung Galaxy Note 9 Review: Pen Wielding Android Powerhouse
Galaxy Note 9: Thermals Performance, Web Browsing And General Use Benchmarks
A Note On Throttling, Or Lack Thereof
Before we dive into our performance benchmarks, there's an advantage the Galaxy Note 9 has currently, perhaps versus many other phones on the market, and that is that it sustains its performance over time and extended use. Samsung claims the new Galaxy Note 9 has a 3X larger heat spreader and a "carbon-water" cooling system. This may sound like a bit of marketing hype but a recent teardown did show the Note 9 is much better-equipped than its predecessor. Furthermore, our own recent Benchmark Bake-Off of the Galaxy Note 9 versus the OnePlus 6 proves out Samsung's claim that the Note 9 does not throttle, at least not to any significant degree. However, other phones (like the OnePlus 6, though we love that device - review inbound) can bleed off as much as 5 - 10 percent performance over time due to thermal saturation. In fact, it has forced us to rethink our testing methodology moving forward to include some extended use benchmarking, to look for thermal throttling conditions in handsets. Again, our Benchmark Bake-Off is a quick read and worth your time.Good benchmark practice dictates running an app at least two or three times for accuracy, but regardless, and bottom line, what you see for Galaxy Note 9 benchmark results on the pages ahead will be representative of their results after 1 run or the 10th run. This also speaks volumes for those of you who plan on breaking out your best Fortnite over extended sessions on the new Galaxy Note 9.
For our first tests we're using the JetStream benchmark for Javascript performance and RightWare’s Web Test 3.0 for comprehensive, mixed-media web performance analysis, including HTML5 rendering. Here we'll primarily determine how the Galaxy Note 9's Snapdragon 845 SoC handles this workload, along with the Android Oreo operating system and Chrome web browser...

Here the Samsung Galaxy Note 9 puts up the second best scores we've seen, just behind the OnePlus 6, which in the case of our unit sports 8GB of RAM, versus our Note 9's 6GB setup.

In the GeekBench test, we're stressing only CPU cores in a handset (not graphics), with both single and multi-threaded workloads. The test is comprised of encryption processing, image compression, HTML5 parsing, physics calculations, and other general purpose compute processing.

Geekbench is a bit more strenuous and extended testing versus the other two above and the Galaxy Note 9 now moves into the lead spot, with the fastest Android phone score we've seen to date by just a hair in the multi-core test and just a hair behind the OnePlus 6 in the single-core test.

Futuremark's PCMark for Android is a new benchmark addition here for us, so we have fewer results in our database of tested phones to show you. However, this is an excellent suite of tests that we highly recommend for benchmarking performance of a handset with heavier-duty tasks for things like image and video editing, as well as lighter-duty workloads like email, and web browsing. When you see the test running live it's clear the scripted application tests are carefully selected and tuned to make use of the platforms involved in a very controlled way.

AnTuTu’s latest benchmark returns a number of metrics ranked with somewhat nebulous scores, rather than frame rates or time to complete. We tested with the latest version of AnTuTu across all platforms including Android, iOS and even Windows Phone. AnTuTu returns four top level performance metric results that we are including here: CPU, RAM, 3D, UX (or User Experience), along with a total score.

We will say anecdotally that the Galaxy Note 9, in general, just feels snappy and responsive, never once playing catch-up to daily usage requests we would make of it.
Let's test some gaming and graphics applications, next...
