Raspberry Pi Foundation publishes benchmark results of Raspberry Pi 5, scoring more than twice that of the previous generation

Raspberry Pi 5 , announced at the end of September 2023, is equipped with Arm's CPU 'Cortex-A76' and independently developed I/O controller 'RP1', and the performance of the CPU and GPU is 2-3 times higher than that of Raspberry Pi 4. It is said to have doubled. The Raspberry Pi Foundation, which develops Raspberry Pi, has published the results of comparing benchmark scores with the previous generation Raspberri Pi 4 on its official blog.

First, the Raspberry Pi Foundation uses Geekbench 6 to measure benchmark scores. Rather than just crunching meaningless numbers, Geekbench runs tests based on common ways you use your computer, like loading websites, rendering PDFs, and adding filters to images. It is designed to.

Geekbench's CPU benchmark measures two types of performance: single-core and multi-core. However, due to the nature of benchmarks, Geekbench scores can also vary widely from run to run. Setting force_turbo=1 in the configuration file will make things a little better, but the Raspberry Pi Foundation says that it is still necessary to run it many times and average the results to get the correct measurement result.

Additionally, if you're running a 64-bit version of the Raspberry Pi OS, a 16KB page size is enabled, resulting in slightly better performance at the expense of compatibility with ARMv7 32-bit binaries. . Therefore, it seems that they are testing using both 16KB and 4KB page sizes on Raspberry Pi 5.

Below are the single core performance results. Performance measurements were performed over 100 times and averaged.

The multi-core performance results are as follows. Raspberry Pi 5 has more than twice the score of Raspberry Pi 4 in both single-core and multi-core.

The Raspbeery Pi Foundation also publishes the results of overclocking the Raspberry Pi 5. As a result of overclocking the CPU from 2.4GHz to 3.0GHz and the GPU from 800MHz to 1GHz, the single-core score improved by 1.2 times. However, multi-core tests showed little performance improvement. The Raspberry Pi Foundation believes that this is ``probably due to memory bandwidth constraints.''

The Raspberry Pi Foundation also shares the results of benchmark verification conducted by volunteers. Engineer

Jeff Gearing has published the benchmark results on GitHub below, and the Raspbeery Pi Foundation has found that the encryption performance of Raspberry Pi 5 is approximately 45 times faster than Raspbeery Pi 4. I'm taking it up.

Furthermore, Core Electronics, an Australian electronic parts mail order site, also publishes the results of benchmark verification as shown below. You can see that Raspberry Pi 5 outperforms Raspberry Pi 4 overall.

And the Raspberry Pi Foundation introduces

the benchmark by technology blog SeeedStudio as ``the most interesting benchmark.''

SeeedStudio is characterized by using ncnn, a deep learning inference framework for mobile. It is said that GPU acceleration is provided via the Vulkan API, and the graph below summarizes the results of testing on Raspberry Pi 5 and Raspberry Pi 4. The shorter the bar graph, the better the performance, and you can see that the score of Raspberry Pi 5 is higher than the score of Raspberry Pi 4 in both cases.

The Raspberry Pi Foundation says, ``The Raspberry Pi 4 released in 2019 was equipped with a 1.5GHz quad-core Arm Cortex-A72 processor, which was approximately 40 times faster than the original Raspberry Pi model in 2012.However, the 2.4GHz quad-core Equipped with an Arm Cortex-A76 processor, the Raspberry Pi 5 delivers 2x to 3x faster CPU and GPU performance, approximately 2x faster memory and I/O bandwidth, and is the first Raspberry Pi flagship device. We're proud of the performance improvements we've made, but what's even better is to see how much progress we've made over the past few years in real-world applications. It's something that people who are working in the industry can really feel.'
