Apple’s recently announced M3 and A17 Pro chips feature several significant improvements to parallel processing, which results in major performance gains for apps and games that utilize the Metal API.

In a developer talk (video), Apple explained that these new GPUs utilize Dynamic Caching, hardware-accelerated ray tracing, and hardware-accelerated mesh mapping to achieve improved performance.

Dynamic Caching allows the GPU to allocate exactly the right amount of register memory for every action it is taking. This frees up previously unavailable register memory, allowing for many more shader tasks to occur in parallel.

Flexible on-chip memory allows the GPU to utilize all of its on-chip memory for any memory type, rather than having fixed memory allocations for register, thread group, and tile memory. This means that actions that heavily rely on one type of memory can utilize the entire span of the on-chip memory, and even overflow actions into main memory.

Hardware-accelerated ray tracing and hardware-accelerated mesh shading take portions of the calculations for these tasks out of the GPU function, passing them to dedicated units. This allows for more parallel operations to occur, speeding up these tasks significantly.

What does this mean for developers?

Developers don’t need to make any changes to their apps to see performance improvements with M3 and A17 Pro. However, there are a few things they can do to maximize the benefits of these new features:

• Execute FP16 math in their programs, as the high-performance ALUs execute different combinations of integer, FP32, and FP16 in parallel.
• Use flexible on-chip memory to allocate the right amount of memory to each action.
• Design their apps to take advantage of hardware-accelerated ray tracing and mesh shading.

Apple went into more detail about their new silicon GPUs in their video presentation. You can watch it to learn more.

There’s been a spate of rumors related to the upcoming mobile chipsets including the new Apple A17 Bionic and Qualcomm Snapdragon 8 Gen 3. Multiple leaks relating to configuration details have already surfaced, and the recent benchmark test enabled us to compare both the chipsets’ performance. An alleged Geekbench listing has revealed the performance score of Apple’s 3nm-based A17 Bionic chipset.

According to X tipster @NaveenTechWala, the Apple A17 Bionic scored 3269 in the single-core and 7666 in the multi-core test. Meanwhile, the Snapdragon 8 Gen 3 for Galaxy with 1x Cortex-X4, 5X Cortex-A720 attained a score of 2223 in single-core and 6661 in multi-core. It is clear from these results that Apple A17 offers 47% improved performance in single-core test and 15.1% higher in multi-core with respect to Snapdragon 8 Gen 3.

The performance improvement by switching from a 4nm node to a 3nm node can be widely seen in the Geekbench results. However, a similar improvement is seen in the Graphics performance when Apple A17 garnered a score of 30669 in Geekbench’s Compute Benchmark. It registered an exciting improvement over the iPhone 14 Pro score of 23000 and the average iPhone 14 Score of ~15000.

However, the source has not provided a direct link to the Gekekbench results which results in some skepticism. We suggest taking this leak as a grain of salt in the ocean.

Along with the benefits of the new 3nm built Apple A17 Bionic, there could be a slight increase in the pricing for iPhone 15 Pro and Pro Max due to an expected upsurge in the chipset manufacturing costs.

The Geekbench results also confirmed a clock speed of 3.7GHz that matches previous data from leaks and rumors.

Increasing Competition

Apart from the Apple A17 Bionic and the Qualcomm Snapdragon 8 Gen 3, MediaTek Dimensity 9300 is also set to take on the competition and aims to outperform prior chipsets. The chipset is expected to launch in October with 8-core all-big-core architecture.
