There have been previews of Qualcomm’s Snapdragon 820-soc containing many benchmarks of a test device. The 820 scores better than the Snapdragon 810 that is in many high-end phones this year, but has to give way to the Apple A9 in many areas.

Particularly in benchmarks leaning on performance per core, the A9 scores much better, while the 820 takes the lead in benchmarks using the four Kryo processor cores in the 820, according to results and analysis from both Anandtech and Tom’s Hardware. posted.

The Adreno 530 GPU also takes the lead in some tests, showing a significant improvement over the Adreno 430 in the Snapdragon 810. In browser benchmarks, the Apple A9 leaves the Android competitors far behind. Qualcomm states that Chrome is not yet optimized for its own Kryo cores.

The sites ran the benchmarks on a development device from Qualcomm itself, which turned out to have a 6.2″ display with a resolution of 2560×1600 pixels. Often the performance of such devices is only indicative of what a soc does in final devices, especially because Qualcomm makes further optimizations later and the software of manufacturers themselves influences how the soc performs.

The Snapdragon 820 is a quad-core with two Kryo cores at 2.1GHz with 1MB L2 cache and two Kryo cores at 1.5GHz with 512KB L2 cache. The Snapdragon 810 has four Cortex A57 and four Cortex A53 cores. The soc comes from the factories of Samsung, which makes the 820 on a 14nm FinFet process.

The soc will be available in smartphones from next year, presumably from spring. The successors of the LG G4, HTC One M9 and Samsung Galaxy S6, among others, may have the 820 on board. It is the first time that Qualcomm has a 64-bit soc with its own microarchitecture. It supplied socs with its own Krait processor cores for years, but switched to ARM’s Cortex designs in order to quickly move to 64-bit processors.

Qualcomm is not alone in making its own 64bit design based on ARM architecture. Apple has been doing that for several years, most recently with its Twister processors for the A9 soc. For its next Exynos 8890, Samsung is also partly switching to a self-designed microarchitecture.
