13.75 million kcal is 0.01598 GWh, not 58 GWh. So with the 5x multiplier, that's 0.08 GWh for a human.

The distance from Shenzhen to Long Beach is some 300 times the distance from Long Beach to Pasadena, depending on where exactly in Pasadena and which route you take. The CO2 emissions factor for a truck is some 10-100x that of a container ship. The exact ratio depends on what kind of truck, and what scope of emissions are being included. The more one accounts for, the more it will favor the boat. But overall, the emissions from the oceanic leg of the trip are probably anywhere from 1-3x those of the truck.

Global production of titanium is about 210,000 metric tonnes. [1] An iPhone 15 Pro Max has about 18 grams of titanium in it. [2]

Rounding 18 up to 20 for the slightly larger 16 Pro Max, Apples sells 231 million iPhones per year. (210,000,000,000 grams)/(20 grams/iPhone * 231,000,000 iPhones) = 50.72

Apple is using at most 2% of the world's titanium. Obviously many of their phone sales are of smaller or titanium un-endowed models.

Current Ryzen and EPYC processors have 8 core CCXs. The 6 core parts used to be as you described, but are now a single CCX. The Zen C dies have two CCXs, but they are still 8 core CCXs, and are always symmetrical in core count.

The big exception is that the new Zen 5 Strix Point chip has a 4 core CCX for the non-C cores. I think the Zen 4 based Z1 has a similar setup but don't remember and couldn't quickly find the actual information to confirm.

Nevada has no nuclear power plants, and gas accounts for 56% of its power. The Hoover Dam only provides about 4% of the state's energy. Partly because the power from the Hoover Dam is split up between the surrounding states, and Las Vegas only gets about a quarter of it.
