News Intel Quietly Launches Flagship Cascade Lake-SP CPU

"It should be noted, though, that Intel’s major customers don’t pay anything close to the list price."

Typically, anyone who buys in bulk from anyone negotiates a discount. There's nothing special about Intel.
 
"With a list price of $15,460, the 300 MHz higher base frequency come at a premium of almost $5,500 compared to the 8280’s $10,009. "

"And the 8284 is still not Intel’s most expensive chip. That dubious honor goes to the Platinum 8280. "

Umm, what??

lol, good catch.

There's three 8280 variants. The "L" variant is $17,000+
There's also an "M" variant and a regular - no letter designation variant. The article didn't reflect this.
