Has anyone a good benchmark C# program to test TinyCLR running on the 216Mhz STM32F7 mcu?
It would be great if already exist results on othe mcu …
This chip is really flying …
The result on TinyCLR 0.9.0 are for 20 PI decimals:
STM32F429 (168 mhz) : 2.44 sec
STM32F746 (216 mhz) : 1.32 sec
On STM32F746, allocating heap on external SDRAM time goes up to 3.11 sec … weird!!!
Benchmark is compiled in Debug.

I have seen the same speed drop on Discovery429 with external ram.
I assume the issue might be the fact ram is being accessed using 16bit vs 32bit.

Is your stack located in internal ram?
