The Snapdragon 820 SoC is currently amongst the most powerful mobile processors out in the market. This is Qualcomm's 64-bit quad-core processor which has been utilized in many smartphones this year, including devices from Xiaomi, Samsung, HTC, LeEco, Motorola, etc. That being said, we've been hearing rumors regarding the Snapdragon 821 and 823 for quite some time now, and one such handset had surfaced on AnTuTu quite recently. A new LeEco handset was listed along with the Qualcomm MSM8996pro processor, which could be either the Snapdragon 821 or Snapdragon 823, we cannot say for sure.
That being said, two new variants of the Snapdragon 820 surfaced on Zauba, the Indian import and export site. Zauba frequently reveals new devices that are being imported into India for testing, and now we have a pair of Qualcomm-branded chips, it seems. The Qualcomm MSM 8996SG (001-Y8) is the more powerful of the two, this SoC is clocked at 2.35GHz, and its Adreno 530 GPU runs at 653MHz, while it also includes second-gen Hydra cores, just like the other chip we'll talk about in a second. This chip also offers support for LPDDR4 RAM, 3x CA at 60MHz, and CDMA (just like the other variant). The other chip comes with the MSM8996SD (001-Y8) model name, and it is clocked at 2.15GHz, while it ships with the Adreno 530 GPU which runs at 624MHz.
Both of these processors have been imported from the U.S., and it seems like we're looking at either the Snapdragon 821 or 823 CPU variants here. Qualcomm still did not officially announce either of these two chips, but the announcement might come soon considering how many leaks are we seeing at this point. The Xiaomi Mi Note 2, Mi 5S and the recently leaked LeEco smartphone are all rumored to be fueled by one of these two chips, and we're sure that more Android manufacturers are planning to do that very same thing in the coming months. Judging by the leaked info, the Snapdragon 821 and 823 won't be that much different than the Snapdragon 820, though they will be somewhat more powerful. Either way, stay tuned, we'll report back as soon as more info surfaces, as usual.
