The GD32F330RBT6 is powered by a 120 MHz ARM Cortex-M4 core, which significantly outperforms the STM32F103R8T6, which is based on a 72 MHz ARM Cortex-M3 core. The higher clock speed of the GD32F330RBT6 allows for faster execution of computational tasks, enhanced real-time processing capabilities, and better handling of complex algorithms in applications such as motor control, industrial automation, and data processing.

In terms of memory, the GD32F330RBT6 provides 512 KB Flash and 128 KB SRAM, allowing for larger code storage and smoother handling of memory-intensive operations. The STM32F103R8T6, on the other hand, offers only 128 KB Flash and 20 KB SRAM, which limits its ability to store more complex firmware and handle larger datasets effectively. This gives the GD32F330RBT6 a clear advantage in memory capacity, enabling more advanced applications without the need for external memory.

Additionally, the GD32F330RBT6 includes a comprehensive set of peripherals, such as SPI, I2C, USART, CAN, and multiple PWM channels, offering greater flexibility for various system designs. The STM32F103R8T6, while providing SPI, I2C, and USART, lacks some of the more advanced peripherals found in the GD32F330RBT6, limiting its versatility in certain applications.

GD32F330RBT6 vs. STM32F205RET6: Enhanced Memory and Peripheral Flexibility

Both the GD32F330RBT6 and STM32F205RET6 are based on the ARM Cortex-M3 core, running at 120 MHz. Despite similar core architectures and clock speeds, the GD32F330RBT6 offers superior memory capacity, with 512 KB Flash and 128 KB SRAM. The STM32F205RET6, while offering 512 KB Flash, only provides 64 KB SRAM, which can limit its performance in data-heavy applications. The GD32F330RBT6’s larger SRAM ensures smoother operation, especially when handling large data buffers or complex algorithms.

Moreover, the GD32F330RBT6 offers more advanced peripheral options, including CAN, SPI, I2C, USART, and multiple PWM channels, which are ideal for applications in industrial control, communication, and motor control. In comparison, the STM32F205RET6 offers CAN and a similar set of basic peripherals, but it lacks the variety and flexibility in PWM options that the GD32F330RBT6 provides.

From a cost-efficiency standpoint, the GD32F330RBT6 delivers more features at a competitive price, making it a more attractive option for developers looking for a high-performance solution without compromising on cost. The STM32F205RET6, while slightly more expensive, does not offer a significant performance gain in memory or peripherals.

GD32F330RBT6 vs. STM32F107RCT6: More Processing Power and Peripheral Integration

The STM32F107RCT6 runs on a 72 MHz ARM Cortex-M3 core, which is slower compared to the 120 MHz Cortex-M4 core in the GD32F330RBT6. This clock speed difference enables the GD32F330RBT6 to perform tasks more quickly and handle more complex operations, providing a substantial performance boost in applications requiring higher processing power, such as automated machinery and real-time data processing.

In terms of memory, the GD32F330RBT6 again leads with 512 KB Flash and 128 KB SRAM, compared to the STM32F107RCT6, which offers 512 KB Flash but only 64 KB SRAM. The extra SRAM in the GD32F330RBT6 allows for more efficient data management and a smoother operation in memory-intensive tasks.

Additionally, the GD32F330RBT6 offers a broader range of peripheral support, such as CAN, SPI, I2C, USART, and multiple PWM channels, allowing it to meet the needs of more sophisticated systems. The STM32F107RCT6, while providing similar peripherals, is more limited in terms of PWM capabilities and does not offer the same variety or flexibility as the GD32F330RBT6.
