avxthrowaway: Thank you very much for joining the Intel® Processors communities.
In order to provide the most accurate response I will do further on this matter. As soon as I gather the information needed I will post all the details on this thread.
Any further questions, please let me know.
If the Core i7 Skylake X models do in fact have the full AVX512 throughput, I'm curious to know how all the pre-release reviews got it wrong. Where did they get their information from?
If you look at the detailed Skylake Server product pages, you can see that it is clearly marked whether they have 1 or 2 x FMA units: ("# of AVX-512 FMA Units")
- Intel® Xeon® Gold 5120 Processor (19.25M Cache, 2.20 GHz) Product Specifications
- Intel® Xeon® Gold 5122 Processor (16.5M Cache, 3.60 GHz) Product Specifications
But if you look at the product pages for the Skylake X parts, the "# of AVX-512 FMA Units" spec is missing.
- Intel® Core™ i7-7800X X-series Processor (8.25M Cache, up to 4.30 GHz) Product Specifications
- Intel® Core™ i9-7900X X-series Processor (13.75M Cache, up to 4.30 GHz) Product Specifications
I don't know whether it was intentionally left out or whether it was just an oversight.
I am still waiting for a comment on the original question. Can you please provide a link to the second datasheet for the Skylake-X processors? The first one is here for reference
I'm assuming since this product is released, you have the second datasheet and haven't updated your links to it?
I look forward to your response.
JeffHammond, thank you for your patience.
