Qualcomm Snapdragon 865 vs Snapdragon 855 Plus: Performance comparison

Qualcomm Snapdragon 865 vs Snapdragon 855 Plus: Performance comparison

We have the benchmark numbers from the Snapdragon 865.

Here's how flagship phones in 2020 will perform.

Qualcomm announced the Snapdragon 865 earlier this month at the Snapdragon Tech Summit in Hawaii. Usually there’s a long gap between Qualcomm announcing the chipset and knowing the actual performance of the flagship chipset since OEMs take a couple of months to get their devices ready for market. But not this time.

This year, just as the Snapdragon 865 was announced on stage, we were handed reference devices powered by the flagship chipset, and with the usual benchmark apps installed. And we spent some time using the device and putting it through the benchmarks a couple of times to get the required scores. We then compared the scores against 2019’s best performing device — The OnePlus 7T Pro. Without being clickbaity, we can assure you results will leave you surprised.

But before we get into the test-results, let’s first note down the advantages of having the Snapdragon 865 powering your smartphone —

1. The Snapdragon 865 is manufactured on TSMC’s 7nm N7P process, the same process that is used to make Apple’s A13 Bionic chipsets.
2. This time Qualcomm has retained the CPU architecture from the Snapdragon 855 and there’s a 2.84GHz prime core running on the Kryo 585, three Cortex-A77 mid-cores clocked at 2.4GHz and three Cortex-A55 efficiency cores clocked at 1.8GHz. So heavy tasks like games, 4K videos, and more will be handled by the prime core, slightly heavier tasks like editing a photo will be handled by the mid-cores, while everything else will be processed by the efficiency cores.
3. The Snapdragon 865 also uses a new displays, 10-bit HDR and 90FPS gaming. You will also get regular GPU driver updates on the Google Play Store.
4. Qualcomm claimed the CPU and GPU on the Snapdragon 865 are around 25 percent faster and 25 percent more power efficient.
5. Apart from the CPU and GPU, the Snapdragon 865 boasts of a new ISP capable of crunching 2 gigapixels per second and enable 8K video recording among other things, a new AI Engine that’s now much faster, more efficient and can do things like in-call live translation!
6. Finally, the Snapdragon 865 will have to be paired with the Snapdragon X55 5G modem, so rest assured most flagship Android phones next year will be 5G ready.

Now that we have a fair idea of the new features, here’s how the Snapdragon 865 performs —

Snapdragon 865 vs Snapdragon 855+ Benchmarks Comparison

The reference device we tested the chipset on sported a 5.9-inch 2880×1440 pixel display, 12GB LPDDR5 RAM, 128GB storage and of course, was powered by the Snapdragon 865. We ran AnTuTu, Geekbench 5 CPU, PCMark Work 2.0 and GFXBench Offscreen tests to gauge how well the chipset performs.

Here are the results —

On AnTuTu, the Snapdragon 865-powered reference device clocked in 541899 in the second run while Geekbench Single Core and multi-core CPU score clocked in at 933 and 3473. We also ran PCMark Work 2.0 where the Snapdragon 865-powered device scored 12386 points. We also tested the GPU performance using GFXBench Offscreen benchmarks. 1440p Aztec Ruins clocked in 1298 frames, while 1080p car chase clocked in 2,960 frames and 1 080p Manhattan offscreen clocked in 5,428 frames. Now these numbers by themselves don’t mean much. But if you compare it against the fastest smartphone of 2019, you get a better idea of where the Snapdragon 865 stands.

As against the OnePlus 7T Pro powered by the Snapdragon 855 Plus, the Snapdragon 865’s was about 11 percent better on AnTuTu, 15-18 percent faster on Geekbench CPU, and around 14 percent faster on PCMark Work 2.0.

The Adreno 650 GPU, when compared against the enhanced Adreno 640 on the OnePlus 7T was around 7-9 percent faster on GFXBench offscreen tests. 
Looking at the scores with added context, the Snapdragon 865 doesn’t seem to be as fast as Qualcomm is claiming to be. Qualcomm claimed an impressive 25 percent boost in CPU and GPU performance, but we are only seeing around 15 percent boost in CPU and around 9 percent boost in GPU performance. 


As you can see from the results above, the Snapdragon 865-powered reference device was only around 15 percent faster on CPU benchmarks and around 9 percent faster on GPU tests. Nowhere did the reference device clocked the claimed 25 percent better performance. But then again, this is just a reference device based on which other OEMs will design their products. And as such, it lacks the necessary optimisations that makes phones like the OnePlus 7T Pro run like a race car. We will have better parity in our test subjects once the actual commercial units powered by the Snapdragon 865 start coming to the market. But till then, it seems the Snapdragon 865 is not much of an upgrade, at least in CPU and GPU performance, over the Snapdragon 855+.
