Wow, quite pathetic results.

The floating point results are suspiciously good compared to the rest of the results. I wonder if they have some good VLIW instructions for floating point or it’s just an error in the spreadsheet.

Linpack is a floating-point benchmark focused on linear algebra operations. Coremark has some floating-point-heavy benchmarks in its suite, although a common criticism is that the footprint is too small to exercise the memory system.

So yeah, the "Maximum MFLOPS" row looks suspicious.

VLIWs tend to do well for programs with predictable-at-compile-time memory access patterns which tends to correlate with floating point heavy code.

The 28nm lithography half-node is almost ten years behind the state-of-the-art.

Apple, Intel, AMD all have commercially available products based on 7nm now.

Is that bad thing? I mean, computers from 10 years ago still kick ass today.

For HPC it is a huge handicap, though. Intel's 10nm process offers about 10 to 12 times higher transistor density than their 32nm process, for example. So, if you want to be fair, you should take this into account when comparing chips.
