 Snapdragon 8 Gen 2 deep dive- Everything you need to know

Snapdragon 8 Gen 2 deep dive- Everything you need to know

In Hawaii today, Qualcomm unveiled the Snapdragon 8 Gen 2, its most recent mobile platform. Qualcomm’s most recent addition to its flagship Snapdragon series builds on the Snapdragon 8 Gen 1 in more ways than one, and it includes a variety of enhancements and new capabilities for premium smartphones in 2023 and beyond.

While you can find our concise summary of the most important talking points below, there is a lot more to go into in more depth. The Snapdragon 8 Gen 2 boasts several firsts for Qualcomm, including an entirely new CPU cluster configuration, a GPU with ray tracing capabilities, premium audio features and connectivity, and a deeper integration of photography and machine learning.

Snapdragon 8 Gen 2 CPU arrangement explained

The switch from the tried-and-true 1+3+4 CPU cluster structure to a more innovative 1+4+3 architecture is one of the Snapdragon 8 Gen 2’s most immediately obvious modifications. Additionally, Qualcomm chose to use two alternative CPU cores in the middle/performance cluster, based on two more recent Arm Cortex-A715 processors and two older Cortex-A710 processors. Although it’s obvious that this was a very particular design decision, it will inevitably improve multi-core benchmarking numbers.

Qualcomm claims that the purpose was to keep supporting older apps. The Cortex-A710 is Arm’s final 32-bit application-supporting core (AArch32); theoretically, all succeeding and future cores will only handle 64-bit apps (AAarch64). The Snapdragon 8 Gen 2 additionally makes advantage of Arm’s updated Cortex-A510 tiny cores, which as of 2022 may be designed with 32-bit capability and have a 5% decrease in power consumption.

Ensuring legacy 32-bit support results in a unique CPU layout in the 8 Gen 2

The updated A510s from Qualcomm are in fact constructed with 32-bit compatibility, offering a total of five cores that can run legacy software. This should deliver an adequate level of performance for 32-bit programs that surpasses the four A510 core support observed in the Mediatek Dimensity 9200 when combined with the two A710 performance cores. It will be interesting to watch how more demanding older software performs as they won’t perform as well as 64-bit apps on this CPU, which can utilize all of the chip’s cores. Perhaps yet, considering the loss of one tiny efficiency core, 32-bit compatibility may be unnecessary for many Snapdragon users and even a terrible battery life trade-off. To address the problem, Qualcomm claims to have further tuned the performance cores.

See, from 2019, Google has required 64-bit application capability. Any software that has been updated recently on the Play Store is now 64-bit. However, the inclusion of the A710 and updated A510 cores guarantees that the Snapdragon 8 Gen 2 will function with both current and non-Android ecosystem software. Consider China or independent app marketplaces that are more behind in requiring 64-bit capability.

An extra middle core will boost multi-core workloads, but what about low-power use cases?

Along with the additional middle core, a powerful Arm Cortex-X3 completes the CPU clusters and contributes to the stated 35% performance gain. According to Qualcomm, efficiency has improved by up to 40% overall. Given the loss of one efficiency core, it’s still a remarkable number. The majority of this is attributable to the switch to TSMC’s 4nm process (Qualcomm wouldn’t confirm whether it is using the older N4 or newer N4P process, so we’re assuming the former). When Qualcomm switched production of the Snapdragon 8 Plus Gen 1 from Samsung to TSMC, we observed comparable advantages.

We don’t have complete cache information, which may have an impact on how well the efficiency and middle cores perform. However, Qualcomm has increased the shared L3 cache to 8MB from 6MB, which will help to maximize performance with the additional middle core in strongly multi-threaded applications.

Q. How fast is Snapdragon 895?

With the integrated X65 5G Modem, the new Snapdragon SoC will boast wireless download speeds of up to 10GB/s compared to the Snapdragon 888’s 7.5GB/s. The Snapdragon 895 will also use the Armv9 architecture, making it among the first SoC’s to do so.

Q. Which Snapdragon is the fastest?

  • The Snapdragon 8 series powers most high-end smartphones on the market today.
  • Qualcomm’s flagship GPUs are generally considered to be the best out of all Android chipmakers.
  • The Snapdragon 7 Gen 1 offers some flagship stylings, such as a powerful CPU and 4nm design.

Q. Is Snapdragon 870 5G good for gaming?

The fastest GPU in this series is this one. Fast enough to handle games like FREE FIRE and PUBG MOBILE is the Qualcomm Snapdragon 870. The GPU score is higher than the Qualcomm Snapdragon 870, so using this chipset will result in a more fluid gaming experience. The GPU runs at 675 MHz.
