That's almost certainly wrong information. Cortex A72 is an out-of-order CPU unlike Cortex A53 in RPI3. Also Graviton is running at 2.3 GHz vs 1.4 GHz for RPI 3b+.
You'd expect 16 core Graviton to outperform RPI3b's 4 core A53 by about 8-15x.
- Zenst 8y agoA little digging and it would appear this set of benchmarks are single threaded, so a 2x speed improvement given the clock speeds makes sense. I have looked at some other benchmarks, and it looks like this offering only pays off on certain tests (N-Queens being one), how that pans out with real-world usage is what we will find out over time. Though the aspect that even in a few tests that this stands out, makes it viable for some real-world usage. Time will tell and at least even if it pays of in 1 out of 10 tests, those tests will translate into real usage. But one shoes does not fit everybody, but always good to have a choice and for that, this is good.
