7985WX has a base clock frequency of 3.2 GHz and a maximum boost clock frequency of up to 5.1 GHz for a single core, depending on workload and thermal conditions.

Yes, I am using affine coordinates for batched addition, as it is more efficient for certain operations.

That's weird. I have over 17 MK/s per core on a Laptop CPU: i9 13900H and it's only running at 3 GHz.

This with a batch size of 512 constant elements, adding a single point (middle) left and right in a range of 1025. Higher batch sizes have diminishing returns, below measurable.

This is futile though, since the hashing is the bottleneck, it will never matter if the EC throughput increases.

Let's assume we can hash at 6 MH/s per core.

With 12 MK/s EC throughput/core, we end up with (12 * 6) / (12 + 6) = 4.0 M op/s
With 24 MK/s EC throughput/core, we end up with (24 * 6) / (24 + 6) = 4.8 M op/s
With 100 MK/s EC throughput/core, we end up with (100 * 6) / (100 + 6) = 5.66 M op/s

etc...
