Qualcomm Snapdragon Summit: What’s new with Snapdragon 8 Gen 3
Today at Snapdragon Summit, Qualcomm announced their 2024 flagship mobile chipset: Snapdragon 8 Gen 3. Below is our thoughts on what is significant and a recap of the main announcements.
Gen AI is being a popular marketing term and also a differentiating factor for a lot of consumer and enterprise products right now. Qualcomm is heavily pushing the local Gen AI movement. They announced a new AI Stack for developers to run on their local AI Engine, which will use the GPU, CPU, and CPU simultaneously to run these models. They claim 20 tokens per seconds of performance on the 7B parameter Llama 2 model and Stable Diffusion image generation in under 1 second. While these are both useful benchmarks, it’s unknown how Qualcomm partners are going to use this raw power and AI Engine in first party apps and services. We know the SoC can run these models locally, or hybrid locally, but not how they will provide value to consumers and enterprise.
Qualcomm is using the a new 1+5+2 core setup for the CPU, with 1 ARM Cortex X-4 prime core, 5 ARM Cortex A720 performance cores, and 2 ARM Cortex A520 efficiency cores. This is a pretty classic core setup, and early benchmarks put the single core performance slightly behind Apple’s A17 Pro with multi core performance right on par with A17 Pro. Apple does have a silicon advantage with TSMC’s 3nm node vs the TSMC 4nm node Qualcomm is using for Snapdragon 8G3. We’ll have to see how this performance plays out when devices with Snapdragon 8 Gen 3 start shipping, which will start with the Xiaomi 14 series in China in the coming weeks.
Google also announced that they had models meant for on device AI for their specific apps in the works, likely meaning the local Gen AI features from Pixel 8 series will not be exclusive to Pixel, but will roll out to high end flagship mobile phones in the future.
We’ll have to see how Qualcomm’s AI Stack, AI Engine, and performance stacks up to the competition as devices hit the market. We’re likely to see devices in Mainland China throughout October and November with global devices launching starting in December.
