Qualcomm will present its new SoC (Snapdragon 8150) on December 4th. We will then know the exact specification of the chipset that will power the most important next year flagship smartphones. In spite of this, new leaks are appearing in the network, revealing further details. This time we learned the operating frequencies of individual cores and the amount of L2 cache memory.
One thing is for sure. Snapdragon 8150 will be the most efficient mobile processor on the market. This is evidenced by benchmark results from various sources and leakages regarding its specification. The new Qualcomm’s SoC will have an octa-core processor. The basic tasks will be performed by a set of four “silver” cores with 128 KB of L2 memory and a maximum clock frequency of 1.768 GHz. Most likely, they will be Cortex-A55 systems. However, among the “golden” cores will be one with 512 KB L2 clocked at 2.842 GHz and 3 cores with 256 KB L2 and operating frequency up to 2.419 GHz. It is assumed that the “golden” cores will be Cortex-A75 systems.
What about the rest of the Snapdragon 8150 specification?
The new chipset will also get a more efficient graphics layout. This is supposed to be Adreno 640. However, for us the most interesting are wireless communication modules. The new LTE-Advanced modem should support data rates up to 2 Gbps. This value is going to be achieved by aggregating 20 LTE streams with 256 QAM modulation and a 20 MHz channel bandwith. Each such stream offers a bit rate of about 100 Mbps. How does it translate into practice? A base station capable of transmitting 20 streams will have to be equipped with radio modules from 5 bands operating in 4×4 MIMO mode. Unfortunately, not many operators in the world have so many frequency bands for LTE networks. However, the emergence of faster modems may prompt operators to start frequency refarming process.
The new Snapdragon 8150 should also work with the Snapdragon X50 5G modem. At the same time it is not known whether the new 5G modem will be an integral part of the chipset, or maybe it will just communicate with it through a dedicated interface.
