Apple Silicon 13-inch MacBook Pro nearly as fast at machine learning training as 16-inch MacBook Pro

While Apple still needs to fully optimize the M1 processor and its software for the task, a 13-inch MacBook Pro with Apple Silicon performed nearly as well at a machine learning test as the 16-inch MacBook Pro with dedicated Radeon graphics.

Benchmarks for the M1 processor have been impressive so far with scores rivaling even the most expensive Intel MacBook Pro configurations. These are early days yet as software continues to be optimized for the processor, so some tasks and processes will see big speed jumps as developers take advantage of the hardware.

One space that the M1 processor should excel in is machine learning (ML) processes. As with Apple’s A-series chips like the A12Z Bionic, the M1 has a dedicated Neural Engine used for complex data processing and ML. Apple says the M1 Neural Engine can handle up to 11 trillion operations per second when in use.

This processor is not best in class in terms of machine learning however, as dedicated GPUs from companies like Nvidia boast even higher numbers for neural operations. The first generation of Macs running Apple Silicon only have the M1 processor to rely on— no additional GPU options are available.

The developers at Roboflow wanted to pit Apple’s new machines against the older Intel variants. The processor transition has only just begun for Apple, so tools like TensorFlow have not yet been optimized to run for a full benchmark test.

The testers chose to use Apple’s native tool called CreateML, which allowed developers to train a machine learning algorithm with object-based learning and no written code. The tool is available on the M1-based Macs, so the testers believe it should have been properly optimized to perform the test.

They chose to compare the 13-inch MacBook Pro with an M1 processor and 8GB of RAM to the 13-inch MacBook Pro with Intel Core i5 and 16GB of RAM which has a dedicated Intel Iris Plus Graphics 645 card. The 16-inch MacBook Pro with an Intel Core i9 processor, 64GB of memory, and a dedicated Radeon Pro 5500M was also tested.

The Roboflow team decided to run the test with a no code object recognition task. They used the 121,444 image Microsoft COCO object detection dataset, then exported the assets using…
