How to compute or test the Peak floating-point performance of Arria10?

In the product table of Arria10, I see the Peak floating-point performance of Arria10 GX1150 is 1366GFLOPS, the number of Hardened single-precision floating-point multiplers/adders is 1518. ​ So, i...

And @ 900MHz => 900*1518=1366GFLOPs. (I'm not saying the is how they spec'd it, just my observation).

Arria 10 will certainly run bits of logic at 900MHz but the practicalities of running 1518 multipliers at 900MHz is another, especially when the datasheet specifies 548MHz max speed for floating point multiplication in a grade 1 part.

Nothing concrete to go on I'm afraid. I'd put it down to the art of writing a spec.

Cheers,
