Drafting: This technical assessment compares the computational performance and power efficiency of the original Raspberry Pi Pico (Cortex M0+) against the Raspberry Pi Pico 2 (Cortex M33 and RISC-V). Benchmarking was conducted using a single-core Pi approximation algorithm (100,000 iterations) on an Arduino-based platform. The results demonstrate that the Pico 2’s ARM Cortex M33 cores, equipped with a hardware floating-point unit (FPU), significantly outperform the original Pico in both speed and energy efficiency. Conversely, the Pico 2’s RISC-V implementation showed substantially lower performance in floating-point tasks compared to the original M0+. Overclocking tests further delineated the performance ceilings of both architectures, while power consumption analysis confirmed the Pico 2's superior efficiency when utilizing ARM cores.

0:01:48 - Benchmark Methodology: Single-core Arduino sketch calculating Pi via 100,000 iterations. Testing conducted at default frequencies and under overclocking conditions.
-
0:02:14 - Default Frequency Test (ARM): Pico 2 (M33) @ 150MHz finished in 3.6s; Original Pico @ 133MHz finished in 5.6s (~35% faster).
-
0:02:57 - Default Frequency Test (RISC-V): Pico 2 (RISC-V) @ 133MHz finished in 3.9s (~30% faster than original Pico's 5.6s).
-
0:03:51 - Overclocking Performance (ARM): Original Pico @ 240MHz (3.98s) vs. Pico 2 (M33) @ 300MHz (2.8s).
-
0:04:16 - Overclocking Performance (RISC-V): RISC-V @ 150MHz (8.8s) and @ 133MHz (9.9s) performed significantly slower than the original Pico's 5.6s. Overclocked RISC-V @ 240MHz reached 6.3s, still slower than the original Pico @ 240MHz (4s).
-
0:05:25 - Power Consumption Analysis: Original Pico (133MHz: 46mA; 240MHz: 60mA). Pico 2 (M33) (150MHz: 42mA; 300MHz: 55mA; 50MHz: 34mA). Pico 2 (RISC-V) draw is comparable to M33.
-
0:06:14 - Conclusion/Key Takeaways: Pico 2 M33 is superior for floating-point math due to FPU and improved architecture. RISC-V underperforms in this specific workload due to lack of FPU and immature compiler toolchains.
