If Intel can remove (or eliminate most of) the memory gap (via lowered latency of future Optane generations) that will affect how CPUs are designed.I . . . dunno about that, unless Intel wants to give up on the CPU business and just provide Optane memory/storage products for everyone.

Post #45If Intel can remove (or eliminate most of) the memory gap (via lowered latency of future Optane generations) that will affect how CPUs are designed.
In fact, speculative execution is a result of CPU design that compensates for memory gap.

Be that as it may (and I do not think Optane will do what you think it will; it eliminates the gap between storage and memory, not the gap between memory and cache), it's unclear how or why the CEO would have to be an Optane evangelist.If Intel can remove (or eliminate most of) the memory gap (via lowered latency of future Optane generations) that will affect how CPUs are designed.

The CPU performance is tied to the memory though......so if Intel can reduce the memory gap (even somewhat) that will make their future Xeons more efficient. Just think about reducing the need for speculative execution on performance per watt as one example.Right now, Intel's major source of revenue is the server room. They have to protect their Xeon market. The previous two CEOs have attempted to break into other markets with little success. The first order of business for any incoming CEO (not counting interim CEOs) is to execute on existing projects perfectly, so as to buy them enough time to recover from their current design/fab woes. In general, they have to move their server lineup onto Sapphire Rapids, and they have to move desktop onto Ice Lake. ASAP. As a logical extension, that means cleaning up the fab mess by hitting targets for 10nm+ and 7nm. Everything else is either a stop-loss measure or a side-project in comparison.
Once they have their core business stabilized, they can maybe shift focus to one of their other projects.
Optane is still considerably slower than DRAM.The CPU performance is tied to the memory though......so if Intel can reduce the memory gap (even somewhat) that will make their future Xeons more efficient.

So I think future versions of Optane ( a form of phase change memory) is not really separate from CPU. In fact, I have to wonder if it is through memory that Intel will functionally extend Moore's Law (ie, not literally, of course, but from a performance and efficiency standpoint).
This is why I think the next CEO will take a more integrated approach. (ie, treating future CPUs and future generations of Optane memory as something that needs to be thought of as one unit.)
Good question!I do wonder what will happen to BK's side projects when the new CEO comes in. Which ones will get binned in the great clear out? I suspect that at least a couple of the AI acquisitions will get "streamlined", and I don't know if dedicated GPUs will still get the support and funding they need to compete with NVidia.
Well hey, if you can get the job, maybe you can do something about that.So I think future versions of Optane ( a form of phase change memory) is not really separate from CPU.
Yup, it is. Last time I checked, the only real advantage it had over NVMe anything is in rapid small file transfers.Optane is still considerably slower than DRAM.
Yes, the current generation of Optane (which is used in the Apache Pass DIMM) is slower than DRAM.Optane is still considerably slower than DRAM.
