AMD just announced Ryzen PRO with "Built-in AES 128-bit Encryption engine" so will that have any impact on mining?

I found the announcement, it would have been nice if you had posted the link.

It's all marketing speak so I have no idea what it means technically. AES_NI is already a 128 bit encryption
and decryption engine so I have no idea what improvements are implied, maybe a faster implementation.

Another implied improvement is the mention of low-latency cache. Intel cache performance is currently better
than AMD so maybe the're catching up. That combined with the larger-than-Intel cache size could further give
an edge to AMD in the CPU market.

With Ryzen they have pulled ahead of Intel with threads, price, cache size, HW SHA. Between Threadripper
(4 channel DDR4, more threads, even bigger cache) and whatever improvements come in the Ryzen Pro there's
not much left where Intel has an edge.

It's nice to see some real competition in the CPU market. It will be interesting to see how Intel will respond.

On a bit of a tangent...

I am still curious about AVX2 performance on Ryzen. I have read that their implementation isn't native but I haven't
seen any performance comparisons. If anyone has a Ryzen I would be interested in a performance comparison of
AVX vs AVX2 on algos that have AVX2 optimizations.

If you can list the algos you would like tested I can try it out on both Ryzen R7 1700X and R5 1600 CPUs. Possibly on Threadripper too towards the end of summer if I talk myself into getting one. Wink
