Its not really a clone its a different single board computer. A72 on pi4 is more powerful than the a55 on c4. GPU might be better on c4.

- adrian_b 6y agoCortex-A72 is faster than Cortex-A55, but only when it is well cooled, which will never happen on a credit-card-sized computer, unless you use either a noisy fan or a passive heatsink larger than the board. ODROID-C4, as delivered, with only a small passive heatsink, can run indefinitely with all cores at 2 GHz, without overheating. Therefore a Raspberry Pi 4 without improved cooling will be in many cases slower, due to throttling, despite the larger Cortex-A72 cores. Moreover, Cortex-A72 implements an obsolete instruction set, while Cortex-A55 implements the ARMv8.2-A instruction set, which for certain applications, e.g. for the synchronization of multiple threads (i.e. for atomic instructions), has significant improvements.
