Qualcomm usually releases its latest system on a chip (SoC) at the end of the year, and by the end of 2022, the Snapdragon 8 Gen 2 should be released.
The SoC is rumored to have a unique CPU configuration, different from the Snapdragon 888 and Snapdargon 8 Gen 1 -- which actually also have a different CPU configuration than the previous SoCs.
Snapdragon 8 Gen 2 is expected to use a 1+2+2+3 CPU configuration, not 1+3+4 like the two previous SoCs. The CPU configuration in Snapdragon 8 Gen 2 will consist of a Cortex-X3, two Cortex_A720, and two Cortex-A710, and three Cortex-A510.
Or if you refer to the code name, the core is divided into 1x Makalu-Elp, 2x Makalu, 2x Matterhorn, and 3x Klein-R1, as quoted by GSM Arena, Tuesday (14/6/2022).
Makalu and Matterhorn are the successor cores of Cortex-X1/A78, where Matterhorn is X2/A710 and Makalu is the next generation, namely Cortex-X3/A720.
.
In terms of performance, Cortex-X3 and A720 are claimed to have 30% higher CPU performance than the X1/A78, and a small increase compared to the faster cores in Snapdragon 8 Gen 1. It is assumed that this performance is calculated from the same clock speed.
The reason is Snapdragon 8 Gen 2 (SM8550 or code name Kailua ES) will be made using TSMC's N4 process, which according to Digital Chat Station is the same process for Snapdragon 8+ Gen 1. So there probably won't be a big clock speed increase there. .
But what is clear is that Snapdragon 8 Gen 2 will probably be the first mobile SoC to use four different types of CPU cores. Hopefully this core configuration can produce high performance and be balanced with a capable power efficiency as well as a decrease in the heat generated.
Regarding the GPU, it is said that the SoC will use the Adreno 740. However, there is not much information about the GPU specifications, except that it uses the same architecture as the Adreno 730.
The launch of the SoC is usually carried out by Qualcomm at the end of every year at an event held in Hawaii, United States. It's also possible that Qualcomm used Hawaii-themed codenames for the chips.
