Do you happen to have any idea what happened with Intel's research into near threshold voltage operation? IIRC they were talking about this in the early 2010s, targeting voltages as low as 0.3v.
They just stopped talking about it.
That's why germanium transistors were the rage for a while because it had Vth of 0.3V but it's still not here. Also it's one thing for a single transistor, it's another thing for a whole CPU. Also what frequency will they run at? Low Vth and germanium is good, but not so much at 2GHz.
Advancements were made for sure for CPUs to reach 6GHz. Years ago they were talking about more resilient circuitry techniques for higher frequency operation and they might have been using that now. Those were the good old days of IDF.
Which brings us back to the subject at hand - Gelsinger and his legacy. This information, on high cost of Intel packaging is another piece of evidence how delusional Gelsinger was - in ignoring the costs. Probably thinking Intel would be so far ahead in performance and technology that Intel can charge whatever price they want, and customer will pay.
Gelsinger was likely betting more than that, such as the lockdown premiums continuing. When that stopped the demand plummetted.
There's a company that offers ebike renting service and they haven't been making much money either. The ones where they are randomly put in spots with only a phone needed to unlock, pay and use them. I think they are not far off from bankruptcy. They appeared around the same time period. So few companies also bet on that continuing. They were also way too expensive. But convenience beats not having debt for some people I guess.
Sorry, I shouldn't have used Apple and Qualcomm as examples there, since they use large shared caches to eliminate the need for an L3...
But L2 caches are usually counted as part of the core. Any core private cache usually is. Hence why the figure of "13mm2" without any context isn't very useful.
L2's aren't really private. It's easy to add, hence why we don't include them in the figures. Everybody can do them. But can they actually make a good CPU? The smarts are in the uarch, not the higher level caches.
Also unless the "private" cache is in the range of 10MB, vast majority of that 13mm2 is the core, and I doubt it was included.
AMD also beats Lion Cove substantially. Remember Zen 5 is on the older process.
