The first Qualcomm Snapdragon 835 benchmarks are out and the results are a mixed bag
Some smartphone makers have taken to designing their own chips, Notably Samsung, Huawei and
Xiaomi, but Qualcomm’s flagship Snapdragon processors have always set the tone in the market. The 800-series Snapdragon chips are the cream of the crop.
An SoC (System-on-Chip) is an all-in-one chip that houses all the electronics your phone needs to function. This includes the modems for wireless connectivity, the processor for logical calculations, the storage unit, RAM, image-processing unit and so on.
Qualcomm, like other chipmakers, usually license processor core designs from ARM, a chip designer, and then integrates it into the SoC. Qualcomm’s expertise lies in designing a cohesive SoC, and they’re very good at it.
Production issues have limited the availability of the new chip and Samsung, which is making the chips for Qualcomm, is also hogging the first production run for its own phones. Because of this, we haven’t yet seen any new smartphone with an SD 835 SoC, and don’t expect to see one until the Galaxy S8 arrives later this month.
Qualcomm unveiled the technical specifications of the new chip and some performance benchmarks to AnandTech at the company’s San Diego headquarters.
First, here’s how it stacks up against the Snapdragon 820:
|SoC||Snapdragon 835||Snapdragon 820|
|CPU||4xKryo 280 at 2.45GHz, 4xKryo 280 at 1.9GHz||2x Kryo at 2.15GHz, 2x Kryo at 1.59GHz|
|GPU||Adreno 540 at 710MHz||Adreno 530 at 624MHz|
|RAM||LPDDR4x at 1866MHz||LPDDR4x at 1866MHz|
|Camera support||1x 32MP or 2x 16MP||1x 25MP or 2x 13MP|
|Modem||Snapdragon X16 LTE||Snapdragon X12 LTE|
The Kryo 280 CPU cores are not a direct upgrade to the 820’s Kryo cores however. Qualcomm designed the first Kryo cores in-house, and they were very good, offering a major performance bump over the ARM-designed Cortex cores that Qualcomm used in the Snapdragon 808 and 810.
The Kryo 280, however, is again an ARM-designed Cortex core, but with some modifications. As part of a new licensing regime, chip makers can now ask ARM to make some modifications to ARM’s Cortex cores. The rights to these modifications are owned by ARM, but will not be available to any other manufacturer. It’s not clear why Qualcomm choose to go this route rather than build their own cores, as they did previously.
Anandtech speculates that Qualcomm is using modified ARM Cortex A73 cores. The new Adreno 540 GPU is a Qualcomm design however.
Image: QualcommCPU-only tests reveal that the SD835 performs around 10-22 percent better than the SD820 and that it beats competitors by a slim margin. This is in integer tests, which is more relevant for web browsing and other day-to-day activities performed on your smartphone.
The platform does appear to falter in floating point operation tests, where it’s around 23 percent slower than SD821. This may not affect real world performance much.
GPU tests are where the new chipset really shines. The Adreno 540 is already clocked around 14 percent higher than on its predecessor. Overall, performance appears to be over 25 percent better than before, concludes Anandtech. It also handily beats the iPhone 7 in these tests.
All things considered, it seems that the Snapdragon 835 is indeed faster than the generation it replaces. However, its performance is apparently very comparable to Huawei Mate 9’s Kirin 960 SoC.
